gmung960 Munger

The gmung960 utility modifies text section and/or data section load address(es) in an object file.

gmung960 is useful when you need to load text and/or data at an address other than where it was linked. A common case is where code must copy its data to RAM before execution. In this case, the data will be linked at the RAM address, but it must be loaded at a ROM address from where it will be copied.

The invocation command is:

gmung960 [ -option ]... file

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

file identifies the object file to be "munged." It must be a linked, executable file.

• D [ addr ]
  Changes the load address of file's data section to addr. addr is interpreted as a decimal number, unless preceded by 0x (hex indicator). If addr is omitted, the load address is the first available address following a previously specified address. (See the T [ addr ] option, below.)
• h
  Gives a help message.
• T [ addr ]
  Changes the load address of file's text section to addr. addr is interpreted as adecimal number, unless preceded by 0x (hex indicator). If addr is omitted, the load address is the first available address following a previously specified address. (See the D [ addr ] option, above.)
• v960
  Writes gmung960 version information to stdout and exits without doing anything.

Note that the section specification options T and D are processed in the order they appear in the invocation.
