Crain) Lines: 1941 Approved: allbery@uunet.UU.NET (Brandon S. Allbery - comp.sources.misc) 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. :alex Alex Crain Systems Programmer alex@umbc3.umbc.edu (NEW DOMAIN!) Univ Md Baltimore County nerwin!alex@umbc3.umbc.edu 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 :-). ------------------------------ snip,snip,snip --------------------------------- #!/bin/sh # shar: Shell Archiver (v1.22) # # Run the following text with /bin/sh to create: # ChangeLog # DIFFS # Makefile # README.diffs # constant.c # kernal.h # parseifile.h # parseifile.y # sed 's/^X//' << 'SHAR_EOF' > ChangeLog && XWed Jan 18 00:45:24 1989 Alex (alex at nerwin) 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.
