This program allows you to display information about the structure of an
Amiga executable file (or a link object). HunkFunc requires OS2.0 for work.
The first version of this program is made with help of HunkFunk utility
made by Olaf Barthel. But as Olaf's utility misses a lot of hunks and
other information, I made my own tool. This version knows a lot more
possible configurations and is shorter, as it uses Amiga functions instead
of ANSI-C.
Know hunk types are: HUNK_UNIT, HUNK_NAME, HUNK_CODE, HUNK_DATA, HUNK_BSS,
HUNK_(ABS)RELOC32, HUNK_(REL)RELOC16, HUNK_(REL)RELOC8, HUNK_EXT, HUNK_SYMBOL,
HUNK_DEBUG, HUNK_END, HUNK_HEADER, HUNK_OVERLAY, HUNK_BREAK,
HUNK_DREL32, HUNK_DREL16, HUNK_DREL8, HUNK_LIB, HUNK_INDEX,
HUNK_RELOC32SHORT, HUNK_RELRELOC32, HUNK_ABSRELOC16, HUNK_PPC_CODE,
HUNK_RELRELOC26.
The File has following argument line:
"FILE/M/A,SREL=SHOWRELOC/S,SSYM=SHOWSYMBOL/S,SEXT=SHOWEXTERN/S,
SEREF=SHOWEXTERNREF/S,SOVT=SHOWOVERLAYTABLE/S,STATS/S".
FILE You must pass at least one file name, but may pass a lot more.
Patterns are not supported.
SHOWRELOC displays all reloc entries (there may be really much of them!)
SHOWSYMBOL displays symbol names of HUNK_SYMBOL
SHOWEXTERN displays definitions of HUNK_EXT
SHOWEX-REF displays references of HUNK_EXT
SHOWOVERL. display data of overlay table
STATS show short statistics about file
Example output:
File 'C:AddDataTypes':
HUNK_HEADER
Numhunks = 2 (0 to 1)
Hunk 000 = 5560 ($0015B8) Bytes
Hunk 001 = 160 ($0000A0) Bytes
HUNK_CODE 5560 ($0015B8) Bytes
HUNK_RELOC32
Summary 5 entries to hunk 1
HUNK_END
HUNK_DATA 160 ($0000A0) Bytes
HUNK_RELOC32
Summary 14 entries to hunk 0
HUNK_END
- First line shows program name.
- HUNK_HEADER is the first hunk of an executable and lists all the hunks.
There may be additionally comments like CHIP, FAST, ADVISORY or MEMTYPE.
- HUNK_CODE and HUNK_DATA store information.
- HUNK_BSS store memory space, which is filled with 0 on startup.
- HUNK_RELOC32 (and other types) hold relocation information.
- HUNK_END ends an hunk entry.
- In HUNK_CODE, HUNK_DATA and HUNK_BSS the memory flags may be repeated
in first or second longword. The flags is displayed normally when in
second longword (size) and preceeded by a '_' (e.g. _CHIP), when in
first longword (hunk type).
- HUNK_DREL32EXE is in real a HUNK_RELOC32SHORT which uses wrong ID due
to a bug in OS V37.
