ghist960 Statistical Profiler

The ghist960 statistical profiler facilitates statistical analysis of the execution behavior of programs containing debug information. To use ghist960, compile your program with the g (Debug) option and link it with the libhis profiling library. Executing the program with representative inputs causes a profile data file to be created. Specify this file when invoking ghist960.

The ghist960 invocation command is:

ghist960 [ -option ]... program [ data_file ]

Each option must be preceded by a - character. (On DOS, you can also use a / character.) The options are listed below.

program identifies your application.

data_file identifies the execution profile data file (ghist.dat by default).

• a
  Print all buckets with one or more hits. Normally, ghist960 prints only buckets with 1% or greater of the total hits.
• d
  Prints a complete dump of ghist960's internal symbol table in addition to the standard data.
• f
  Tallies the number of hits for each of the line numbers of the functions in the application, and associates them with the function itself.
• h
  Writes help information to stdout and exits without doing anything.
• n
  Prints the absolute number of hits for each bucket in addition to the standard data.
• s
  Suppresses printing of miscellaneous header and footer information and format lines.
• V
  Writes version information to stdout and continues.
• v960
  Writes version information to stdout and exits without doing anything.
