ChangeLog objfiles.c objfiles.h symfile.c target.c main.c
Makefile.in configure.in
Added Files:
os9kread.c os9kstab.c remote-os9k.c
* os9kread.c: New file to read os9000 style symbo table.
* os9kstab.c: new file to read os9000 style stabs.
* remote-os9k.c: remote protocol talking to os9000 rombug monitor.
* objfiles.c (find_pc_objfile): new function to search objfile
from pc.
* objfiles.c (objfile_relocate_data): new function to relocate
data symbols in symbol table.
* objfiles.h: Add two aux fields in struct objfile to handle
multiple symbol table files situation like in os9000.
* symfile.c: Change so 'symbol-file' command can handle multiple
files. Also call target_link() to get relocation infos.
* target.c (target_link): new function to get relocation info when
a symbol file is requested to load.
* main.c (quit_command): take out 'inferior_pid != 0' condition,
because in cross mode there's no inferior pid, bit they need to
be detached.
Makefile.in: add os9kread.c os9kstab.c and .o's.
configure.in: add i386os9k target.
config/i386/i386os9k.mt: new add.
config/i386/tm-i386os9k.h: new add.
