Posting-number: Volume 6, Issue 38
Submitted-by: alex@umbc3.umbc.edu (Alex S. Crain)
Archive-name: 68kdisasm/patch01
These patches are for the 68K COFF dissassembler that passed through
here some time ago. It makes the dissassembler pretty specific to AT&Ts
UNIX-PC, but if you have one of those, it does some pretty neat stuff. See
the ChangeLog file for details.

BTW: some of this code is copyrighted to various people. I didn't
remove any copyrights, but I don't think that I added any here, and at this
point, if you can pull a profit off this sucker, you diserve the bread you
get. Course, you've gotta maintain it :-).

X
X * constant.c [lookp_address ()] - change to return a value for any
X legal shlib address (0x300000 -> 0x380000), instead of the first &
X last symbols.
X
X * kernal.h - fill this file with interesting addresses.
X
X * alloc.c [mkdref ()] allow for addresses to point to objects of
X length 0.
X
XTue Jan 17 11:14:21 1989 Alex (alex at nerwin)
X
X * main.c [doopts ()] - added two globals, kernal and dup_error,
X which are turned on with -k and -D respectively, to turn on kernal
X symbol lookup and DUP??? symbol names (and errors).
X
X * robj.c [dosymb ()] - added a test for dup_error in the case of
X duplicate symbols. If dup_error is not set, duplicate symbols are
X simply ignores.
X
XMon Jan 16 23:53:26 1989 Alex (alex at nerwin)
X
X * constant.c [replaces syms.c] - instead of syms.c, generate
X shlib.h in the same manner. include this file, along with kernal.h
X into constants.c which contains the lookup code. lookup_address ()
X looks up an address in he shared library symbols (shlib.h) and
X returns a symbol and option offset in a single string.
X lookup_kernal_address () is simular but does not calculate an
X offset, retunring 0 if the address is not found.
X
X * iset.c - many small changes
X [prea ()] - output a '&' before a constant hex address.
X [pmovc ()] - format MOVEC as MOV
X [pcs2 ()] - movm becomes mov.m, ouput a '%' before dest register name.
X
XSun Jan 15 22:37:48 1989 Alex (alex at nerwin)
X
X * syms.c [lookup_address()] - this now returns either:
X a) a symbol name
X b) a symbol name + an offset as a single string ("%s+0x%x")
X c) (char *) 0 if the given address is greater then the larest
X known symbol value.
X
X
XMon Jan 9 00:08:25 1989 Alex (alex at nerwin)
X
X * parseifile.c [new file] - generate a file containing a sorted,
X initialized array of shared library symbols that can be loaded
X into the disassembler.
X
X * syms.c [new file] - generated by parseifile.
X
X * iset.c [paddr()] - try to resolve unknown hex addresses by
X first looking them up in the initialized array with
X lookup_address(). If this doesn't work, try to generate a label
X for the address with mkdlab(). At this point we are only printing
X absolute address that don't exist in the text or data areas, and
X arn't referenced in /lib/shlib.ifile.
X
X * prin.c [pdata(), pbss()] - teach the print routines about 0
X length objects. We handle these by searhingthrough memory to find
X the next object, and using the difference as the size of the
X current one.
X
X * prin.c [ptext()] - add a _start symbol to the beginning of the
X text area. Don't verify the entry point, though.
