5/8/96 to 7/25/96 Add an error check in ALIEN:DEF-ALIEN-ROUTINE for pointer-like types being used with :out or :in-out. It sort of worked with c-string, but ended up passing in a pointer to the string data, which is confusing to the uninitiated. Added UNIX:TIOCSIGSEND. Currently only on HP/Ux. Merged patch from PW that makes EXT:PRINT-DIRECTORY handle broken links better. Merge fix from Douglas Crosher to make ACOSH and ATANH return the right thing. Fixed tree-equal as per DTC's patch. Formerly the test would be randomly called on conses, and if it returned true, the result was true. My reading of the spec says that the test should never be called on non-atom values. I put in an additional test to insure this. Don't use SPECIAL as an internal function name, because SPECIAL is an external symbol. Fixed EXT:PROCESS-KILL to work on PTYs under HPUx by using TIOCSIGSEND. Now C-c c works in Hemlock shell mode. Fixed MAKE-SEQUENCE to not specify make-array initial-element when it is not specified in the arg so that (vector float) works (as per suggestion of DTC). Also fixed things to use type system operations so that they should be really robust in the presence of deftype types, etc. Merged DTC's patch to string<>=*-body which fixes various problems that arose when :start2 :end2 values were specified to string=, etc. Merged patch from PW that is supposed to fix decode universal time after 2000. Merge fix from tsm to allow (setf function) names as args to COMPILE. In the compiler, check if we have a funcallable instance before we check if we have an instance in SOURCE-TRANSFORM-INSTANCE-TYPEP. This way, typep of funcallable instance types should actually work. Fixes to motif destroy callbacks from TSM. Flushed redefinition of QUIT in Motif interface. Patch from Jeurgen Weiss to translate-key-event which makes it deal better with european keyboards. Merge debugger patch to print local var names as packaged symbols. Fix defmacro not to give bound-but-not referenced warning when we say &key with no keys. 8/23/95 to 5/8/96 Fixed some broken stuff with -batch switch. Attempt to deal with FINs that have FINs as their functions. Interesting because of PCL/byte-compiler interactions. Added a suite of signed byte output routines because the unsigned ones weren't type correct for signed operands, thus didn't consistently work. Fix parse-namestring of pathnames. On sparc move-to-word/integer, always do arithmetic shift on fixnums, since semantically they are always signed. If for some reason we are moving a negative fixnum to an unsigned reg, we presumably know what we are doing. 2/17/95 to 8/23/95 Added command line switch -batch to support batch mode where input is read from standard input and an error code of 0 is returned if an EOF is encountered, and 1 otherwise. Fix complex rational subtract. Hemlock: Add another call to internal-redisplay in editor-input-method-macro. It doesn't entirely fix the problem with shell output update, but makes it a lot better. In RCS commands, don't try to set write date on systems w/o times. 17f to 2/17/95 Code: In load-foreign use cmucl.orig, not lisp.orig, as the base file on hp-ux. Patch from TSM to make format able to print english numbers of up to nine hundred ninety-nine vigintillion, nine hunderd ninety-nine novemdecillion ... etc. Fix pprint-setq not to call LENGTH on what might be an improper list. Fix bogus simple-vector arg type in sub-output-array-guts. Got mach vs. non-mach conditional backwards in setting up Library:. Fixed broadcast streams to not close the component streams when the broadcast stream is closed. Revision 1.21 claimed to do this, but it lied in the case of broadcast streams. Hemlock: Changed the default for Slave Utility from lisp to cmucl. Motif stuff: Timeout support from Marco Antoniotti. 3/11/94 to 3/20/94 Code: -- Debugger Enhancement from Harris to not abort printing of a frame when printing one arg gets an error. -- In OUTPUT-INSTANCE, check for the layout being invalid before calling the print function, since the print function might error. -- Tweak read-line to work better on a non-persistent EOF (e.g. ^D on TTY) Compiler: -- In byte compilation, don't call valid-function-use on mv-combinations. Don't annotate mv-calls to inline functions or slot accessors as though they were non-mv calls. Tools: -- In inst-lisp, allow separate specification of source and destination releases. Hemlock: -- Deleted some setting of *hack-hunk-replace-line* to T, since we may want it explicitly disabled in the init file. PCL: -- Better handling of obsolete structure instances in generic function dispatch. 2/15/94 to 3/11/94 Code: Changed the default for library: under hpux to be /usr/local/lib/cmucl/lib. Bind *break-on-signals* to NIL even before doing the type test so that we don't wedge the error system if the type is malformed or undefined. Compiler: Changed return to return-from assert-definition-type. Changed assert-definition-type to quietly ignore non function-types. Allow stream arg to compile-file. Deleted incorrect type declaration in process-1-ftype-proclamation. Deleted test for function-type-p around call to assert-definition-type, since this is now folded into the function. Previously several calls weren't doing this necessary check. Do DFO-AS-NEEDED in BYTE-COMPILE-COMPONENT (as it is done in NATIVE-COMPILE-COMPONENT) to ensure that cleanup code has block numbers. Also added some MAYBE-MUMBLE calls for *COMPILE-PROGRESS*. PCL: Patch from Harris. Motif Interface: Don't byte-compile if not :small. Changed ~A to ~D when formatting socket file in case the base isn't 10. Added some fflushes to motifd. Add INVOKE-TTY-DEBUGGER. Don't try to invoke motif debugger if we didn't succeed in opening a connection. Print warning in status hook when server dies. Simplified boolen expression. 2/9/94 to 2/14/94 Profile: -- Fixed %report-times to not choak if any of the function names are not symbols (e.g. setf functions). -- Don't warn about &rest consing if we can't figure out what the argument signature is, because we don't use &rest anymore. -- GET-INTERNAL-RUN-TIME now works under hpux, so go ahead and use it. In cmucl, use &more instead of &rest to avoid consing the &rest arg list. Small runtime (w/o compiler) hacks: -- Add dummy stubs for EVAL:INTERNAL-EVAL, etc. which signal errors when the IR1 interpreter hasn't been loaded. -- Don't try to do verbose ROOM if it isn't loaded. -- Export EXT:PURIFY and remove the :CONSTANTS argument. -- Move environment compacting into PURIFY instead of doing it at top-level in worldload. Now users can do it too. -- Allow pretty-printer to work without compiler loaded. Code: -- Fixed TWO-ARG-GCD to correctly handle most-negative-fixnum. Was choaking because someone declared (- most-negative-fixnum) to be a fixnum. -- Fixed the warning in defpackage about no longer using some packages to actually work. -- Fixed COERCE to use subtypep to analyze the output type spec instead of checking for magic symbols. -- Changed vector to inherit from array before generic-vector. Fixed simple-string to list string in the inherits list. -- Add TTY-IXON mode for HPux. Compiler: -- Changed coerce-to-smallest-eltype to call coerce with a vector type specifier instead of an array type specifier. (necessitated by "fix" to coerce.) -- Tweak CONVERT-CALL-IF-POSSIBLE to not try to convert calls in top-level code which call code in another component (because we already failed to convert the call before.) -- In BYTE-COMPILING, always return T when :BYTE-COMPILE T was specified. This was causing byte-compiled PROGV to flame out. -- Add DELETE-IF-NO-ENTRIES to blow away components that can't be reached before we try to generate IR2. This avoids some internal errors when unreachable local functions are deleted. Tools: -- Changed worldload.lisp to use :RUNTIME feature to suppress loading everything, and to use the new maybe-byte-load and byte-load-over functions to load lots of byte code when RUNTIME is present. -- In worldcom, when NO-RUNTIME feature is absent, compile various subsystems byte-coded as well as native coded so that we can choose at system build time. Hemlock: -- Move the new_compiler branch onto the trunk. -- In READ-BUFFER-FILE, set BUFFER-WRITABLE to T before doing anything so that we don't get spurious read-only errors. -- Move all font name defhvars to rompsite and give them the actual default as their initial value. Change those defaults to be courier, flushing all mention of 8x13. -- Un-conditionalize TIOCSLTC ltchars hacks for HpUx, since they are needed to suppress dsusp. -- Turn off ^s/^q under tty for HPux with IXON off. PCL: Call UPDATE-LISP-CLASS-LAYOUT instead of REGISTER-LAYOUT, since the bare R-L doesn't update the inherits from the CPL. This caused LAYOUT-INHERITS to be left empty when a class was redefined. Motif: -- Added some extra protection against recursive invocation of the windowing debugger. -- Tried to make starting the Motif server more robust, or at least give some intelligible error message. 1/28/94 to 2/9/94 Changed step to set-step-breakpoint because step is supposed to be the exported step macro, not some internal routine. Default the name slot in defmacro-lambda-list-bind-errors to NIL. Added an executable-only optional to unix-namestring so that we can expand path:foo into the first executable in the path named foo, not just the first file. Changed run-program to only try to run executables, and to flame out if it can't be found in path:. Fixed defpackage to combine multiple use, export, and import options correctly. Fixed coerce to call type-expand so that people can coerce to deftypes. Changed the byte-function and byte-closure funcallable-instances to use &more args instead of a &rest arg. Changed main-entry to use etypecase instead of assuming that the arg is always either a lambda or an optional dispatch, because sometimes raw functionals get passed in. This way we will get a better error message. Give a sensible error message if we can't find the slave utility (e.g. lisp) to run. 1/6/94 to 1/28/94 Code: Re-frobbed fd-stream-read-n-bytes to preserve the property of returning less than the requested number of bytes when eof-error-p is NIL and that is what unix-read read. Startup C code: Use /usr/local/cmucl instead of /usr/misc/.cmucl on hpux. Hemlock: Restored the behavior of scribe-file to cd to the directory of the .mss file before running scribe. This was accidentally removed in an attempt to clean up some compiler warnings. 12/11/93 to 1/6/94 In read-n-bytes, only signal EOF when we read and got 0 bytes, not never read returns less than we wanted. Also, fix the case of small reads with an empty buffer not to leave garbled buffer pointers if we have to do more than one read. These changes affect primarily people who read form pipes, like Xlib and Motif. Added all of the ANSI CL features that seemed plausible, since we're closer to ANSI CL than any other version of CL. Any non-ANSI compliance is now a bug, not a feature... YES-OR-NO-P and Y-OR-N-P now force output. Added a derive-type defoptimizer for log. In propagate-local-call-args, don't do anything if there is an optional-dispatch specified. The last fixed entry point won't be referenced by the XEP, so we can't count on that providing a T type input. This caused bogus argument types to be inferred in byte-compiled code. In UNCONVERT-TAIL-CALLS, do ENSURE-BLOCK-START so that we can manipulate the use list. Fixes an assertion failure in the compiler. Call local-call-analyze whenever there's new-functions. This got lost when component-reanalyze-functions was added. Fixes an assertion failure in the compiler, and may result in better optimization. Fix LOAD-TN-CONFLICTS-IN-SC to work for multi-location SCs. Moved bind-to-nil of *LIVE-BLOCK* and *LIVE-VOP* into PACK-LOAD-TNS to better ensure the live-tns are invalidated between two packings of the same block (e.g. for repacking.) These problems showed up with the X86, but could possibly happen elsewhere. Add some hacks to PCL for coercing lisp:class objects to pcl:class. Export make-load-form-saving-slots, not make-load-form-dumping-slots. 12/2/93 to 12/11/93 The Hemlock commands "Typescript Slave Break", "Typescript Slave to Top Level", and other things that send out-of-band data to slaves running on the HP should now work. [That is, the slave will now notice them.] 11/16/93 to 12/2/93 Code: Fixed arg ordering for getf in MAKE-CONDITION. Picked up Miles' changes to apropos and apropos-list that allows one to supply NIL for the package, meaning all packages. Declare hi::%set-variable-value to be a function so that we don't get undefined warnings on loading into a non-hemlock lisp. Compiler: [Sparc] Fixed %more-arg-values to return the count instead of always returning 0. Increase *inline-expansion-limit* from 50 to 200. Change "inline expansion count exceeded" warning to be a note. Don't inline expand when *converting-for-interpreter*. Fixed SOURCE-TRANSFORM-NUMERIC-TYPEP to test against REAL instead of NUMBER when testing reals. Added a define-type-predicate for REAL, so SOURCE- TRANSFORM-NUMERIC-TYPEP can use it. Tools: Changed to make the release arg to inst-lisp useful. Hemlock: Changed from using sed to ul in the "Manual Entry" command, since this works better on HP, etc. Changed rcsci and rcsco to ci and co, which now work at CS, and also work in the rest of the world. Motif Stuff: Added an optional STYLE arg to the graphical inspector to make the function consistent with its doc string (as well as the old inspector). C Start-up Code: Compile -O Don't pass CFLAGS to the linker, since this may clash with the OS_LINK_FLAGS 9/14/93 to 11/16/93 Added breakpoint support and inverse hyperbolic trig functions for the HP. In the debugger, don't flame out on more-args, 'cause they exist now. In describe, fresh-line before calling describe-object method. Generalized condition effective slot computation so that we can find slots with non-constant defaults and special-case them at MAKE-CONDITION time. Fixed format-time to deal with daylight savings time better. [i.e. actually use EDT instead of EST in the summer.] Fix SXMASH util for SXHASH to not be stupid. Fixed COUNT :TEST-NOT to actually negate the test. Flushed #+CLX in serve-event again (somehow reinserted during branchmerge), since we may load CLX even if it isn't loaded at compile time. Fixed decode-universal-time to correctly get the timezone info. Rewrote encode-universal-time to be sane and to correctly deal with timezones. Well, at least they are closer to dealing correctly with timezones. #-hpux'ed utimes, getreuid, and getregid 'cause HPUX doesn't have them. Fixed decoded-time routines to allow timezones of (rational -24 24) instead of (rational 0 (24)), 'cause negative timezones occur east of GMT. 9/13/93 to 9/14/93 Compiler: Fixed a bug in byte compiling in-core dylan code. (This happened when you use the ``Compile Defun'' Hemlock command.) Changed %more-arg-values (one of the companions of &more) to take a count of values to skip, so people don't have to do gross things like assume the context pointer is really a fixnum. Hemlock: Update FUN-DEFINED-FROM-PATHNAME to understand byte functions. 9/2/93 to 9/13/93 Added support for &more, a &rest replacement that just gives you a pointer to the args on the stack and a count instead of consing up a list. This should only be used by those up are in the know, as there are some tricky issues involved. 8/23/93 to 9/2/93 ... 8/16/93 to 8/23/93 Note: you need to recompile everything, because the debug-info structure has changed. Code: Moved lots of stuff around so that more stuff can be byte compiled. Fix from Mike Clarkson. In the alien type= method for function, call ALIEN-TYPE-= instead of calling ALIEN-TYPE-P with two args. Add :CALLERS option to PROFILE which counts the most common callers of each profiled function, and reduced the number of recompiled profile encapsulations. Added a ``DIRECT-SUPERCLASSES'' slot to CLASS so that Dylan can use it. Added support for describing byte-compiled functions. Add support for :EXECUTE keyword to EVAL-WHEN Bulletproof output-instance a bit. Wrote MAP-INTO. Fixed semantics of various type-classes (CL arrays, numbers, functions & alien-types) that have superclasses. This was especially problematic with the Dylan collection heterarchy, but some problems could arise with e.g. (subtypep `(member ,#'cons) '(function (t t) cons)) (not technically legal in CL, but used by the compiler on legal programs.) Compiler: Added direct support for Dylan module-variables. Recognize the new :keyword EVAL-WHEN keywords. Also allow the %coerce-to-function efficiency note in byte code. Enable funcall -> %funcall IR1 transform for byte compilation. Increment warning count after re-signalling so that we don't double-count undefined warnings (where the default handler can be multiply instantiated.) Don't load meta-vmdef and assemfile into the core. Instead, load them before we go to compile the compiler. Flushed call to count-vops (static statistics), since it doesn't work anymore, and isn't loaded. [HP only] Fixed the arg types on generic-eql-c/fixnum to restrict the constant to 9 bits, not 14, because we can only fit 11 bits in the compare-immediate instruction, and 2 are needed for the fixnum lowtag. Changed the stream arg to DISASSEMBLY to be a keyword arg, since it's non-standard, we can avoid option & keyword lossage. Fixed the byte-compiler to correctly handle arguments to local functions that have been deleted. Hemlock: Flush carefully-add-font-path call. If people want library:fonts/ in their font-path, they can put it there. PCL Changed structure-type-p to recognize funcallable structures too. Patch for getting slots of structure classes from Simon Leinen. Add hack to :METACLASS option so that we use the pcl:: (standard object) metaclass, and not the lisp: (structure object) class when we see STANDARD-CLASS or STRUCTURE-CLASS. Changed SPECIALIZER-FROM-TYPE to extract the specializer from LISP:CLASS objects. Fix to CONVERT-TO-SYSTEM-TYPE from Harris. Byte-compile defclass, defcombin, env, and iterate if :SMALL. Wrote stubs for MAKE-LOAD-FORM and MAKE-LOAD-FORM-SAVING-SLOTS. Make OLD-PCL and OLD-SLOT-ACCESSOR-NAME be nicknames during loading. Hacked READ-LOAD-DEFCLASS to return a LISP:CLASS, not a PCL::CLASS. Supply missing :INITIAL-ELEMENT NIL in MAKE-ARRAY call. New definition of NO-SLOT from Harris. Startup Code: Don't reference the various random symbols inside a static data structure, because the SunOS compiler is ``smart'' enough to remove it because it isn't referenced. CLM/Motif stuff: The server process will now call wait to clean up zombie children when running under Mach. There will be at most one process at any given time. Shadow CLASS-DIRECT-SUPERCLASSES because both kernel and pcl want to export it and we want to use them both. 8/4/93 to 8/16/93 Bug fixes: -- Fixed namestring of a stream to not flame out if there is no pathname for that stream. -- Fixed DO-SYMBOLS to iterate over the package-use-list instead of the package-tables, because package-tables gets reordered. Also, various miscellaneous tuning changes indicated by dynamic profiling of the compiler. Some only speed the compiler, but some optimizations are more general (new sequence transforms.) In particular, transform member, delete and assoc to memq, assq and delq when possible. Inline expand vector & list POSITION, vector FILL and list DELETE-IF. Instead of using symbolic links for motifd and site-init, copy them into the release area. This prevents problems with the release area being broken when things are changed in the build area. 7/22/93 to 8/4/93 Bug fixes: -- Fix default-structure-print to just call the accessor (so that it handles raw slots.) -- Pad double-float slot offsets w.r.t. DD-RAW-LENGTH, not DD-LENGTH. -- Changed %COMPILER-ONLY-DEFSTRUCT to be magically called by IR1tran, since eval-when doesn't do the right thing if nested in an another eval-when. -- fixed pprint-do to not flame out if one of the binding lists is NIL. -- (numeric-contagion single-float real) => float, not single-float -- Actually pass the byte-p argument to open-fasl-file so that it really does use the machine-independent byte-code fasl file implementation. Enhancements: -- Logical pathname changes. Pattern-matching on :WILD-INFERIORS is now implemented, but the Unix code treats it pretty much like :WILD. Detect more error cases in TRANSLATE-PATHNAME. Fixed some type declarations that didn't allow :UNSPECIFIC or :WILD when they should. :WILD now appears in the PATHNAME-{DIRECTORY,NAME,TYPE} slots, instead of a :MULTI-CHAR-WILD pattern always being used. -- If the argument to COMPILE-FILE is already absolute, then dump it in the debug-info as the source file, instead of always using the truename. This allows search-lists or logical pathnames to be preserved in the defined-from info. -- PATHNAME of a FD-STREAM now returns the original, unresolved pathname. This preserves search-lists and logical pathnames. -- Add COMPILE-FILE-PATHNAME function. -- Motif: Add Herald display item. Add :MOTIF feature. Now clmcom loads PCL if not already loaded, so it should work in a compiler-only core. Hemlock: -- Fix initialization of print-representation attribute so that characters >127 don't cause text to mysteriously disappear. -- Added hpux support in setup-input and reset-input. -- Fixed "can't edit source" message not to throw you in the debugger when invoked from the command line. 7/4/93 to 7/22/93 The largest changes are: -- PCL port revamped to re-integrate PCL classes with the type system and to more efficiently dispatch on structure and built-in types. Some miscellaneous tuning. CLOS symbols are now exported from the LISP package, so you don't need to USE-PACKAGE PCL anymore. -- New version of CLX: R5.01 PCL notes: This PCL fixes a number of problems that were introduced in the changeover to the new structure format: -- The Lisp type system is now integrated with PCL (even better than before.) -- Structure-class slot-value now works again. Generic function dispatch should be significantly more efficient in this PCL, especially for built-in and structure classes. There should also be reduced run-time compilation (e.g. in the Motif inspector) due to less use of non-precompiled dispatch functions. TYPEP for PCL objects should be faster, and type system integration should be fairly complete. CLOS class names are recognized as "real" types by the compiler, not SATISFIES DEFTYPES. Note that LISP:CLASS is still not a PCL class, so PCL needs to shadow CLASS and STANDARD-CLASS. Misc enhancements: -- Build motif interface as a "library" file for easier distribution. -- Added stuff to allow compile-file and compile-from-stream to be used to compile dylan code. (Assuming you have the dylan to common-lisp converter loaded.) -- Tweeks to allow for compiling/evaling dylan code in a slave. -- Make compiler error functions use the condition system. This ANSI cleanup has two advantages: 1] compiler-warning and warn are now equivalent, so uses of WARN will be counted in the warning total and given source context. 2] user handlers can be defined to notice or suppress output. Misc bug-fixes: -- Do a BOUNDP check so that references to undefined types inside of a WITH-COMPILATION-UNIT but outside of the compiler won't cause undefined-variable errors. -- Set up a default for modules: search-list. -- [sparc,mips] Fixed a bug in default-unknown-values where it wouldn't default the first unsupplied value to nil if more then 6 values where supplied. -- Structure slot accessors are no longer constant-folded, because that was causing problems with some make-load-form hacks. -- Changed BACKQ-UNPARSE to check for improper lists instead of getting an internal error. Some meaningless backq forms will now pprint as "### illegal dotted backquote form ###". -- Added explicit error checking to the debugger so that we don't get an internal error (bus error in unsafe code, etc.) when attempting to display source from a file that has been excessively modified. -- Tweaked compilation of an incompatible defstruct definition to compare to the previously compiled layout, rather than the current run-time definition. -- Added SIMPLE-STYLE-WARNING, and spiffed up the simple-condition hacks so that (typep x 'simple-condition) works. -- Bind *BREAK-ON-SIGNALS* to NIL when we call BREAK in SIGNAL so that the debugger doesn't recurse on itself. -- In LOAD-FOREIGN, use unix-namestring on each file before passing it to the linker to get rid of search lists. -- Fixed a few bugs in DELETE-PACKAGE, and gratuitously rewrote it. Inline the call to MEMBER in DO-SYMBOLS so that we don't waste quite so much time dealing with shadowing symbols. -- Fix compiler-error proxy to not always say FORM as the error form. Class stuff: -- Made CLASS-TYPEP no longer an interface. Block compiled TYPEP. -- Add DIRECT-SUPERCLASSES slot to BUILT-IN-CLASS and initialize it. -- Add FIND-CLASS-CELL, CLASS-CELL-CLASS and CLASS-CELL-NAME to support forward references to redefinable or undefined classes. INFO TYPE CLASS is now a CLASS-CELL or NIL, and the class is actually in the CLASS-CELL-CLASS. -- Added some missing elements in the class-precedence lists of float and number. -- Add stuff to initialize the layout hash. -- Add standard-class and random-pcl-class for representing objects whose real class is a PCL class. Add class-pcl-class slot for tracking the PCL class of any class. -- Changed layout invalidating to set to :INVALID, not T, since PCL uses T to mean valid. -- Add transform for constant FIND-CLASS & change class TYPEP to use the CLASS-CELL make-load-form instead of LOAD-TIME-VALUE. 6/10/93 to 7/4/93 simple-condition-format-string -> simple-condition-format-control Implemented CONDITION-RESTARTS ANSI cleanup & WITH-CONDITION-RESTARTS macro. This provides a way to say that restarts are relevant only to a certain condition. Added style-warning and parse-error conditions. Added report method for end-of-file. Exported cell-error-name. Flushed storage-exhausted and stack-overflow conditions. Don't export hash-table-weak-p from the common-lisp package. Added PRINT-NOT-READABLE condition and made people use it. Renamed get-setf-method-multiple-value to get-setf-expansion and Export COMPILER-MACRO documentation kind. Changed EOF-OR-LOSE to signal the END-OF-FILE condition. special-form-p -> special-operator-p define-setf-method to define-setf-expander. The old names are also defined for compatibility. Made DYNAMIC-EXTENT declaration recognized & ignored. Nuked compiler-macroexpand[-1] because they didn't make it into the standard. Added degenerate versions of stream-external-format, file-string-length and the :external-format argument to open. Changed two-arg-= to use = instead of using eql so that (zerop -0.0) -> t [mips] Lots of tweeks in order to use NIL and 0 directly from the registers holding them instead of copying them into a new register and then using it. [mips] Changed generic-= and generic-/= to not assume that EQ implies =, because it doesn't in the case of NaNs. 6/1/93 to 6/10/93 Fixed clear-input on file descriptor streams to flush any unread chars. Few more minor inspector/describer fixes. Added checking for division by zero on the sparc. Fixed pcl::print-random-thing to flame out if *print-readably* is true. 5/25/93 to 5/31/93 Support for funcallable instances in describe and tty-inspect. Fix byte interpreter so that the fix to make Hemlock/MH work actually takes effect. In Hemlock delete-breakpoints-buffer-hook, if no wire (server died), then don't do anything. 5/20/93 to 5/25/93 Code: Fixed function-debug-function to work on closures. When we tail-call native code from byte code for multiple values, we must un-negate the return PC. Now that +0.0 and -0.0 are no longer eql, fixed atan to deal with them correctly. Added weak hash-table support. Compiler: Fixed the handling of +/- 0.0: - = is no longer converted to EQL, but is directly handled by the backend. - EQL is converted into a raw comparison of the bits. Added LOAD-TIME-VALUE support to the byte-compiler. 5/4/93 to 5/20/93 The largest number of changes are related to the use of byte-compilation for space reduction and the debugging of byte-compilation so that this works. Together with assembly optimization, this has reduced the size of the full MIPS core by 26% and the full sparc core by 14%. Byte compilation overview: The decision to byte-compile or native compile can be done on a per-file or per-code-object basis. COMPILE-FILE now has a :BYTE-COMPILE argument. If T, we byte-compile everything and create a machine-independent fasl file (dependent only on byte order, file type "bytef" or "lbytef".) If :MAYBE (the default, from EXT:*BYTE-COMPILE-DEFAULT*), things are byte-compiled when speed = 0 and debug <= 1. Top-level forms are byte-compiled by default (controlled by ext:*byte-compile-top-level*.) Byte compilation is roughly twice as fast native compilation. Byte compiled code runs 50x--200x slower than native code, and is 6x more dense. This is about 10x faster than the IR1 interpreter, which is itself considered fast in comparison to other Common Lisp interpreters. Historical perspective: this is about as fast as Spice Lisp on a PERQ. Bug fixes: -- Fixed atan to handle zeros better. It still isn't right because the compiler thinks that +0.0d0 and -0.0d0 are similar as a constant. [William has a fix not yet checked in.] -- Fixed PCL not to clobber define-compiler-macro with a NO-OP. -- Changed save to pad the core file out to CORE_PAGESIZE bytes, so that when we mmap it back it, we won't get bus errors if the real page size is less then the CORE_PAGESIZE. -- Use ~C instead of ~A when printing float exponent marker so that print-readable doesn't mess things up. -- Really really fixed get-setf-method-multiple-value for local macros. Also, in the recursive calls, people were not propagating the environment through, and in some places were not recursing with the multiple-value version. -- Added FLOAT-RATIO for precise ratio floating (as need by the float reader.) This avoids roundoff error by doing an integer division. Gratuitous changes: -- Don't load code/inspect if we are loading clm. -- Removed (setf weak-pointer-value) and made make-weak-pointer itself the compiler primitive in order to simplify the gengc port. -- Protect vm:code-breakdown against the debug-source being missing (shouldn't happen but does if compilation is interrupted or something) and against random values being in the debug-info slot (byte compiled code.) -- Added stuff to fake scavenger hooks in the non-gengc system. -- Changed pathname code not to use %primitive to make/access/set value-cells. -- Fixed string and simple-string to include generic-string and vector in their inherits lists. Fixed built-in class creation stuff to use -1 for the inheritance depth if any of the supertypes have -1 for the inheritance depth. Tuning: -- Use an auxiliary function to make the condition for macro arg count errors to save space in macro definitions. -- Byte compile the expander functions for all macros except those in code/ (those may come later.) -- Compile PCL's guts unsafe when #+SMALL. -- Byte-compile most Hemlock commands. -- Some gratuitous RANDOM tuning. Random double floats are now much, much faster. Added transforms for RANDOM to type-specific functions (which can then be inline-expanded). Compiler: Enhancements: Assembly optimization is now enabled, giving large speed/space improvements on MIPS and some on SPARC. This optimization is done when speed > compilation-speed (i.e. not by default) since it significantly slows compilation. Bug fixes: -- When iterating over the lamdba-calls in unconverting tail calls, have to ignore any deleted lambda. -- [mips] removed immediate lognor stuff, because the nor inst can't handle immediate. -- [mips] Added :cost 0 to instructions that were 0 but were defaulting to 1 (for profiler.) -- Fixed instruction scheduler to correctly deal with having a load-word in a branch delay slot. -- Fixed assembler cost incrementer to work with the new block numbering (for profiler.) -- When computing block numbering for debug info/profiling, don't increment until after all references on that iteration... Added a symbol-hash slot to symbols under the gengc system. When symbols are created, this is filled in with a random value. Things that want a fast hashing of symbols but don't want to depend on the address can use this value. Byte compilation: -- If debug-info for a code object is a string, print it (for byte code) instead of assuming it is a debug-info. -- Changed byte-function loading to use funcallable instances. Added support for loading machine-independent fasl files. Made *load-print* do its thing for byte functions. -- Byte interpreter fixes: -- Fixed stack-copy to deal with overlapping upward copies. -- Fixed some index &stack-pointer declarations for indices that could be negative to be FIXNUM. -- Added a comment explaining what the keyword parsing code is doing. Fixed exit test on the keyword parsing loop. -- Made current-stack-pointer a macro so that we won't blow out the inline expansion limit. -- Fixed byte-apply to compute the arglist in forward order when nargs >=8. -- Fixed to potentially grow the eval stack when allocating a frame. -- Byte interpreter enhancements: -- Add system-constants support for fdefinition objects. -- Call different :interpreter-function for inline op if specified. -- Define safe %byte-symbol-value, %byte-car and %byte-cdr operations. -- Add two-arg-stringXXX stubs. -- Moved definition of *eval-stack* here so that we can use byte code w/o the IR1 interpreter (and compiler) loaded. -- Changed byte functions to be funcallable instances. This gives them a recognizable type and allows them to print nicely. -- Moved definitions of byte-functions (formerly byte-xep) here from byte-comp so that we can use them w/o the compiler loaded. Changed byte-functions to have simple and hairy subtypes to save space for the common fixed-arg case. Added a name slot for debugging. -- Byte compiler fixes: -- In PROGV ir1 convert, also use %PROGV for byte compiled code. -- If any top-level vars are closed over, and *byte-compile* is :maybe, then choose native compilation for everything. This ensures that we won't reference a native closure in a byte-compiled top-level form, or vice-versa. -- Have to clear the constant info between compiling each byte-component too. -- Fixed various problems with fasl-dumping byte code: Eliminated some redundant stack/table checking operations. Have to add in vm:code-constants-offset when computing byte-component entry and XEP patch offsets. Bind *unparse-function-type-simplify* to T when getting the type specifier for :type-predicate fixups, since we don't want to check against complex function type specs. -- Actually compute the NUM-MORE-ARGS slot in functions with more args. -- don't add uninteresting BLOCK continuations to the consumes. -- At NLX EP, annotate the stack as empty (ignoring any stuff pushed earlier in the ENTRY block), since they aren't going to be live; UWP NLX EPs are only called when we unwind, and then restoring the stack is someone else's problem. -- Need to annotate the mv-bind continuation as fixed-values. Also, when doing a multiple call for fixed values, must tell canonicalize-values that there are unknown values on the stack. -- Removed byte-output-length. Instead we explicitly finalize the segment so that we have the correct offsets for the entry labels. -- When annotating tail-local calls, make sure the successor is the callee. -- Fixed byte-continuation numbering to be global and to be done for all the continuations referenced in ssets. -- Subtract out the right set in stack flow analysis. -- When moving set args into locals, remember that we number args backwards. -- If block ends in a tail call, don't emit any jump. -- Byte compiler enhancements: -- When byte-compiling, don't do any inline expansion, and suppress many transforms. This speeds up byte code as well as saving space. -- Allow fdefinition system constants. Add some popular functions to system constants. -- Add INTERPRETER-FUNCTION and SAFE slots to INLINE-FUNCTION-INFO to support type-checking inline ops. Put inline funs in a hashtable. -- Add %negate/fixnum, /fixnum, safe-car, safe-cdr, length/list, cons, two-arg list and three-arg list*. -- Add byte-code specific IR1 transforms for EQL/FIXNUM and CHAR=. -- Add two-arg string=, string>, string<. Flushed use of cons-unique-tag. -- Moved byte disassembler here from byte-interp. Enhanced disassembler so that it can dump disassembly in trace file. -- Add pseudo-backend operations which use the byte-order to determine what machine-independent fasl format to use. 4/4/93 to 5/4/93 Initial cut at making PCL work again w/ the new class support. We just shadow find-class, etc. Motif interface and inspector back, and have been fixed to work with the new structure format. Some past changes in the inspector/debugger sources will now be visible: see below. Changed core saving to no longer save the stacks. Instead, when the core is restored, a (supplied) initial function is invoked which can do whatever kind of setup it wants. This makes a saved lisp totally independent of the location of the C stack. [fixing the sun4m sunos problem] Save-lisp must now be called with an init function, and after it finishes, it terminates the saving lisp process, instead of returning. In addition to the change in the save-lisp interface, the main user-visible difference is that there are fewer junk frames on the stack in saved cores. Added the built-in-class REAL. Added the read-only collection built-in-classes needed by dylan. Compiler: -- Don't do assumed function stuff if we have a :NOTINLINE function. This was breaking an assertion. -- Changed FIN-FUNCTION special form to be a new kind of LAMBDA so that we can COMPILE them. -- Moved def-source-context for DEFMETHOD to PCL sources. -- [MIPS only] Fixed unbind-to-here to not dereference past the end of the binding stack. Interface: The debugger will now reuse old debugging panes rather than creating new ones all the time. In addition, the stack backtrace is no longer displayed by default. Replaced uses of Motif gadgets with corresponding widgets. This also fixes the problem with warnings about 'alignment' not being a valid resource. Invoking LISP-CONTROL-PANEL from the TTY now works correctly and QUIT will kill off any Motif servers that you have started. The "Edit Source" button now works. A new button, "Dump Backtrace" has been added. This is for dumping a copy of the stack backtrace for use in bug reports. At the moment, it just prints a copy of the backtrace on the standard output stream. Added support for deleting all active inspection panes. Added comments and descriptions on how to implement inspector display methods for view customization. 4/3/93 to 4/4/93 Added serveral new classes needed to bootstrap dylan. There should be no user visable changes, except that you might have to recompile stuff if something depends on the superclasses of sequence. The loader will tell you if so. 3/15/93 to 4/3/93 [no PCL or CLM] Compiler: Fixed call to CONTINUATION-DERIVED-TYPE to be CONTINUATION-TYPE so that we don't choke on values types in the functional position. Fixed FREEZE-TYPE to seal all subclasses. Profile.lisp updated for new assembler and block-compiler ir1opt. Fixed sparc GET-TYPE vop. Purify: Fixed ptrans_instance to actually return the result of calling ptrans_boxed instead of relying on the result still being in the correct register. 3/1/93 to 3/15/93 [PMAX only, no PCL] New & improved support for funcallable instances so that we can easily define generic function classes for Dylan & CLOS. Also, fixed some bugs in the new structure type stuff: -- Redefinition failing or resulting in spurious errors, # is not a FOO errors, etc. -- Fixed BOA constructors to ignore package when determining if a slot appears as an arg. -- Fixed CIRCLE-SUBST to not bother looking down the instance-layout slot so that splicing structures into the read input doesn't result in CIRCLE-SUBST searching though the entire type system for places to fix up #n#'s. Fixed a bug introduced by tuning (was breaking TTY redisplay): -- Fixed type decls in FILE-POSITION to allow :START and :END for positions. Misc bug fixes: -- Fixed FORMAT-EXP-AUX to correctly handle variable width fields when the argument is negative. -- Fixed info-hash to work again on weird (not SETF) lists. Misc enhancements: -- Improved usefulness of VM:CODE-BREAKDOWN :HOW :FILE by subdividing the files by package. -- Most of the support for Sean's block-counting profiler is in this core, but it's not all there yet. Compiler: -- Fixed a bug in type inference which seems to have generally prevented anything from being inferred about function result types of user-defined functions. -- CTYPE-OF now extracts the function type from function objects, rather than just returning FUNCTION. -- Added FUNCTIONAL-PLIST slot for adding random annotations to functions within the compiler (such as this function is destined to be a funcallable instance.) -- Improved type predicate compilation for sealed classes in general (not just structure classes.) 2/27/93 to 3/1/93 [PMAX only, no PCL] Fixed load to not always consider files with NIL type to be source files. If the file exists as specified, then look at the header instead of trying to default the type. If :CONTENTS is specified, then don't try defaulting types. Replaced ISQRT with the fast version discussed on the net many moons ago. Removed ROOM's load-time dependence on the compiler. Add LIST-ALLOCATED-OBJECTS and LIST-REFERENCING-OBJECTS for finding out why stuff isn't being GC'd. Fixed type system to recognize the codes for internal BUILT-IN-CLASSes such as CODE-COMPONENT. Ripped out NS-BOOT conditionals. Load the byte compiler and interpreter. They don't really work yet, but will be easier to debug if they're in the core. The compiler now has an event counter for compiling a MAKE-VALUE-CELL op. Reduced the size of static space (and the total core) by 1meg by clobbering the hash-table vectors of the obsolete VOLATILE-INFO-ENVs in worldload.lisp. For some reason (probably residual stack or register pointers), the VOLATILE-INFO-ENV doesn't get reclaimed by purify. This meant that much static space was being wasted by the unused SIMPLE-VECTORs and alists, even though the compact version was the one actually being referenced. This was exacerbated by the change to multiple purifies, but has always been present in the new-compiler systems. Also, the Hemlock/CLX info environment wasn't being compacted before the purify at all. 2/9/93 to 2/26/93 [PMAX only, no PCL] New structure format and class support in the type system. Some I/O tuning. New fasl file format (you must recompile.) This core does not contain PCL or the GUI (which depends on PCL.) The old core and startup code are in /afs/cs/project/clisp-3/alphas/olisp.core, olisp. Structures & classes: ANSI changes: -- Default defstruct keyword constructors can no longer reference argument values in slot init forms. BOA constructors can still do this, so defining a BOA constructor with all keyword args will have the old effect. -- Class objects are now implemented, see FIND-CLASS, CLASS-NAME, TYPEP, CLASS-OF. TYPE-OF is now based on CLASS-OF, and returns slightly different results than before. -- STRUCTURE-CLASSes now exist. See also the STRUCTURE-OBJECT type. -- BUILT-IN-CLASSes also exist. In some cases CLASS-OF (legally) returns non-standard subclasses of the standard class, e.g. for a float vector, the result is KERNEL::SIMPLE-ARRAY-SINGLE-FLOAT. STANDARD-CHAR and KEYWORD are now DEFTYPEs. Bug fix: -- Typed structures now have the correct (though rather odd) semantics of :offset and :named when inclusion is done. Raw slots: -- Structure slots of subtypes of SINGLE-FLOAT, DOUBLE-FLOAT and (UNSIGNED-BYTE 32) are now allocated in non-descriptor storage, and can be read/written without number-consing overhead. Type tests: -- The default (non-frozen) structure type predicate is now significantly more faster (no function call) in the case where the argument is a structure of another type or the type is a supertype of the object's type. The code is also somewhat smaller. Redefinition: -- Handing of structure redefinition is now much more comprehensive. -- Definitions are only considered incompatible when slots have moved or been added, slot types are changed to a type that is not a subtype of the old type, or the inheritance structure has changed. Previously any change at all would produce a warning. -- When a change is compatible, the default restart (CONTINUE) invalidates old instances, constructors and predicate uses. When speed <= safety, a LAYOUT-INVALID error will be signalled when obsolete instances are passed to a type test (e.g. for type checking.) Use of old code on new instances or old instances when speed > safety > 0 will result in type errors. Other restarts allow you to ignore the redefinition or to clobber the existing information, preserving the old code (in case the change is really compatible.) -- If the structure length or inheritance structure has changed, an error is signalled when you load code that was compiled with a different structure definition than the one currently in effect. Internals: -- VM:STRUCTURE-USAGE renamed to VM:INSTANCE-USAGE. Internally, the structure type and accessors have also been renamed, e.g. STRUCTURE-REF => %INSTANCE-REF. -- The non-standard STRUCTURE type has become has become EXT:INSTANCE. To (portably) test whether something is really a structure object, do (TYPEP X 'STRUCTURE-OBJECT) Misc changes: ANSI changes: -- #S readed no longer forces keywords into the keyword package. (ANSI) -- Added OPEN-STREAM-P. Added EXT:DO-HASH. Stream internals: -- Deleted read-line methods. For simplicity, this rather unimportant operation is now implemented using read-char. -- READ-N-BYTES eof-error-p nil is now mostly non-blocking (it only reads what is in the buffer, or what unix-read returns if the buffer is empty.) To be sure it won't block, you must guard it with a LISTEN. Misc bug-fixes: Compiler: -- Weaken (not (component-new-functions component)) assertion to allow deleted functions. -- Fixed LET* to correctly use the internal policy (not the interface policy) for all bindings, not just the first. -- Fixed a problem with functions losing their type declaration info when there is an inline expansion available. -- In local call VOPs, must load CALLEE-NFP with MAYBE-LOAD-STACK-TN, since it might not be in a register. [mips] Debugger: -- Changed HANDLE-BREAKPOINT to allow breakpoints that nobody wants. This can happen if a function-end breakpoint was deactivated while the function was on the stack, because there is no way to convert the bogus-lra back into the real lra. Misc: -- Fixed a type error in DEFPACKAGE's detection of defining a package which is really a nickname. Improved handling of deleted packages (most operations signal an error.) Tuning: -- Added declarations from efficiency notes in load, package, reader, char and hash. -- Revived the support for FAST-READ-CHAR and the STREAM-IN-BUFFER, which allows READ-CHAR and READ-BYTE to be done with 0 function calls rather than 2. -- Because of above two changes, both the reader and the fasloader are now significantly faster (reader 2x.) -- Default (non-frozen) structure type tests are now significantly faster (no function calls), and somewhat smaller. This and the reader improvement have sped up the compiler somewhat. -- Many debug-info and compiler data structures are now annotated as pure, alloing them to be put in read-only space. This reduces the amound of stuff in static space, speeding GC. -- Real-valued hash-table parameters (rehash-threshold etc.) are canonicalized to single-floats. -- serve-event now uses UNIX-FAST-SELECT, so it can can handle >32 file descriptors and is more efficient. -- Changed UNIX-FAST-SELECT to a macro so that it can be efficient. Changed FD-SET stuff to be efficiently compilable. 2/4/93 to 2/9/93: Code: Moved foreign-segment-{start,size} from mumble-os.lisp into foreign.lisp, and changed it on the sparc to no longer conflict with read-only space. Changed software-version to use /usr/bin/uname instead of stringing the kernel. [SunOS only] Don't try the (SETF (APPLY ...)) hack for functions with non-fixed args, since it doesn't do anything useful (just converts to a call to the (SETF FUNCTION). Compiler: Fixed listify-rest-arg. It was leaving a tagged pointer to unallocated memory in a descriptor register, which would confuse the garbage collector if this value was still around. Added all the info for the scheduler to the instruction files. Redefined li on the sparc with define-instruction-macro. This allows the schedular to do a better job because the li gets broken up into the seperate component instructions earlier. Fixed make-array-header on the pmax to not seg fault. Fixed the call to note-assembler-routine on the pmax. This was breaking DISASSEMBLE. Changed more occurrences of function-header-code-offset to function-code-offset. (should have them all by now...) PCL: Changed definition of *subtypep to speed up method definition using code provided by Richard Harris. Updated definition of *pcl-system-date* as recommended by Richard Harris. Changed the definition of force-cache-flushes by removing unnecessary call to update-constructors, as suggested by Richard Harris. HP support: Fixed the stuff to emulate the ``addit imm,ALLOC,ALLOC'' instruction at the end of pseudo-atomic to use all 11 bits of the immediate field instead of just 5. Graphical Interface: The inspector/debugger was not behaving properly in the absence of the DISPLAY environment variable. It now correctly senses the lack of X and quietly uses the TTY. 2/2/93 to 2/4/93: Compiler: Fixed VALIDATE-CALL-TYPE to correctly handle calls where there is no function type guarding the call (for example, calls to lambdas). In this case, we still want to call RECOGNIZE-KNOWN-CALL, since it will figure out what leaf we are referencing, and might also do something else interesting: inline expansion, etc. Replaced the FORMAT transform with one that uses FORMATTER for more complete handling of format directives. Fixed make-array-header to not seg fault. Changed more references to function-header-code-offset to function-code-offset. Motif Stuff: Fixed things up so that the StringTable.h file gets written out properly with all the other header files. The debugger should now notice the absence of the Motif server and print an error message to that effect. 1/13/93 to 2/2/93: Code: Fixed COMPUTE-CALLING-FRAME to not try using %CODE-DEBUG-INFO on things that arn't code components. This broke backtracing in the debugger. Don't deftype POSITION, because it is a CL symbol. Compiler: Changed internal error signaling vops to be :translates instead of being accessed via %primitive. Fixed a problem with ASSERT-DEFINITION-TYPE when we have a keyword arg with a non-constant default. Added (values) to the end of %verify-argument-count so it matched the defknown. Changed the defknown for %verify-argument-count to be more precise. Chagned make-xep-lambda to declare the number of supplied arguments as an index instead of a fixnum, because it cannot be negative. Changed def-source-transform to work with setf functions also. Removed source-transforms for internal error things, because we just :translate to them now. Removed header-ref and %string-char-p source- transforms, because we don't need them anymore. Startup Code: Allocate, but protect against reading or writing, the page following each of the heaps or stacks. This keeps os_allocate from deciding to use one of those pages for something else. 12/5/92 to 1/13/93 Code: Backed out the new LOOP, because it breaks something which causes the compiler to generate bad code. Export ARRAY-DISPLACEMENT from the CL package. Changed kernel:code-debug-info to kernel:%code-debug-info. Changed several uses of %primitive to eqv functions now that eqv functions exist. Added COPY-STRUCTURE. Changed %function-header-mumble to %function-mumble. Exported FLOATING-POINT-INEXACT from CL, and renamed & exported FLOATING-POINT-INVALID-OPERATION. Changed di::code-debug-info to kernel:%code-debug-info. Added DO-HASH Export FILE-STREAM from LISP as a synonym for FD-STREAM. Add :INTERACTIVE-P misc method. Call *setf-fdefinition-hook* before we check for encapsulation, since the hook might change the encapsulation. Changed (code-header-ref component vm:code-debug-info-slot) to (%code-debug-info component). Added a #.vm:dylan-function-header-type branch to OUTPUT-FUNCTION. Also added a T branch that prints "Unknown Function" so we get some output when we stumble across unknown functions. Added :cmu17 to the features list so that PCL can tell if it is in a version 16 or a version 17 series core. Fixed a bug in pprint-let that caused to to barf on (let (nil) ...). Added support for dylan funciton subtypes. Changed %print-request-server to use print-unreadable-object to get rid of a spelling error in the old version from pre-puo days. Weaken type declaration on third SELECT result, since it can be NIL if we get an error. Delete #+CLX conditional on HANDLE-QUEUED-CLX-EVENT, since we want to be able to load-time conditionalize whether CLX is present. Exported various slot accessors of streams now part of the standard. Made these read-only slots. Added open-stream-p and interactive-stream-p. Fixed GENTEMP to use its own counter, instead of *gensym-counter*. Added pretty-printer directives to trace so that arg lists and results print better. Fixed untrace-1 not to flame out when untracing untraced functions. Added module.lisp back in, because ANSI added provide and require back in. Compiler: Re-worked the way allocation and primitive slot access are compiled, which should (hopefully) reduce the size of the backend. Fixed defknown of %verify-argument-count to have * for the result type instead of nil. Extended INFO to take the env-list as an optional fourth argument so that we don't have to re-bind *info-environment* to get at info environemnts other then the regular one. In FINALIZE-XEP-DEFINITION, if not the current global definition, just leave the defined type alone, instead of clobbering it with FUNCTION. A benefit of this is that COMPILE doesn't trash the function type. Allow non-keyword keyword names when the &key keyword is specified separately from the variable. Prevent recursive opportunistic inline expansion during IR1 conversion by temporarily clearing the DEFINED-FUNCTION-INLINE-EXPANSION when doing the conversion. Changed the make-closure vop to take the length as an info argument because it is always known at compile time. Changed the set vop to not have a result because we don't want it. Added ANNOTATE-FUNNY-CALL for use with new define-primitive-object stuff. Startup code: Increased the size of the sparc's heap. Changed "environment too big" message to suggest probably a sparc 10. PCL: September-16-92-PCL-e has been incorporated into the CMUCL sources thanks to Rick Harris. 11/23/92 to 12/5/92: Code: Minor fixes to LOOP and DELETE-PACKAGE. Low level support for various subtypes of function for use with Dylan. Pre 12/5/92: For the release notes corresponding to releases prior to 12/5/92, please see the file: alpha-notes-thru-92.txt
