Add auto-solib-add support for AIX, remove obsolete and unused SOLIB_SYMBOLS_MANUAL code, cleanup of AIX shared library handling code. * rs6000-nat.c (vmap_symtab): Do not try to modify offsets if symbols are not yet loaded. (vmap_add_symbols): New function to add symbols for a vmap entry. (add_vmap): Turn errors into warnings, return NULL vmap upon failure. Add symbols via vmap_add_symbols only if requested. (xcoff_relocate_core): Allow debugging of core files without an executable file. Handle NULL returns from add_vmap gracefully. * xcoffsolib.c (solib_add): Remove, no longer needed.

Add symbols for requested shared libraries via vmap_add_symbols. (_initialize_solib): Add `set auto-solib-add' command. * xcoffsolib.h (vmap_add_symbols): Add prototype declaration. * config/rs6000/tm-rs6000.h (PC_LOAD_SEGMENT): Move from here ... * config/rs6000/nm-rs6000.h: ... to here, this is an AIX native feature. * config/powerpc/tm-macos.h, config/powerpc/tm-ppc-eabi.h, config/powerpc/tm-ppc-nw.h, config/rs6000/tm-rs6000ly.h: Remove #undef PC_LOAD_SEGMENT. * config/powerpc/aix.mt, config/rs6000/aix4.mt, config/rs6000/rs6000.mt (TDEPFILES): Move xcoffsolib.o from here ... * config/powerpc/aix.mh, config/rs6000/aix4.mh, config/rs6000/rs6000.mh (NATDEPFILES): ... to here, xcoffsolib.o contains AIX native code only. * rs6000-tdep.c: Remove #include xcoffsolib.h, no longer needed. * xcoffsolib.h (xcoff_relocate_symtab_hook): Remove declaration. * rs6000-nat.c (_initialize_core_rs6000): Remove setting of xcoff_relocate_symtab_hook, no longer needed. * xcoffsolib.c (solib_info, sharedlibrary_command): Remove xcoff_relocate_symtab_hook indirection, call xcoff_relocate_symtab directly, as xcoffsolib.c is now compiled in native AIX configurations only. * Makefile.in: Update dependencies for rs6000-tdep.o, rs6000-nat.o and xcoffsolib.o.

(_initialize_som_solib): Ditto. * pa64solib.c (_initialize_pa64_solib): Add new set/show commands for auto-solib-limit variable. * somsolib.c (_initialize_som_solib): Ditto * pa64solib.c (add_to_solist): Check that auto_solib_add is set and use auto_solib_limit as the threshold size instead of auto_solib_add. * somsolib.c (som_solib_add): Ditto, and also change warning text about size threshold exceeded. doc/ChangeLog: 2001-10-28 Fred Fish <fnf@redhat.com> * gdb.texinfo (auto-solib-add): Change docs to match implementation change. (auto-solib-limit): Add docs for new variable.

If \"on\", symbols from all shared object libraries will be loaded\n\
automatically when the inferior begins execution, when the dynamic linker\n\
informs gdb that a new library has been loaded, or when attaching to the\n\
inferior. Otherwise, symbols must be loaded manually, using `sharedlibrary'.",
Add auto-solib-add support for AIX, remove obsolete and unused SOLIB_SYMBOLS_MANUAL code, cleanup of AIX shared library handling code. * rs6000-nat.c (vmap_symtab): Do not try to modify offsets if symbols are not yet loaded. (vmap_add_symbols): New function to add symbols for a vmap entry. (add_vmap): Turn errors into warnings, return NULL vmap upon failure. Add symbols via vmap_add_symbols only if requested. (xcoff_relocate_core): Allow debugging of core files without an executable file. Handle NULL returns from add_vmap gracefully. * xcoffsolib.c (solib_add): Remove, no longer needed. (solib_info): Do not check for new shared libraries if there is no inferior process. (sharedlibrary_command): Made static. Do not check for new shared libraries if there is no inferior process. Add symbols for requested shared libraries via vmap_add_symbols. (_initialize_solib): Add `set auto-solib-add' command. * xcoffsolib.h (vmap_add_symbols): Add prototype declaration. * config/rs6000/tm-rs6000.h (PC_LOAD_SEGMENT): Move from here ... * config/rs6000/nm-rs6000.h: ... to here, this is an AIX native feature. * config/powerpc/tm-macos.h, config/powerpc/tm-ppc-eabi.h, config/powerpc/tm-ppc-nw.h, config/rs6000/tm-rs6000ly.h: Remove #undef PC_LOAD_SEGMENT. * config/powerpc/aix.mt, config/rs6000/aix4.mt, config/rs6000/rs6000.mt (TDEPFILES): Move xcoffsolib.o from here ... * config/powerpc/aix.mh, config/rs6000/aix4.mh, config/rs6000/rs6000.mh (NATDEPFILES): ... to here, xcoffsolib.o contains AIX native code only. * rs6000-tdep.c: Remove #include xcoffsolib.h, no longer needed. * xcoffsolib.h (xcoff_relocate_symtab_hook): Remove declaration. * rs6000-nat.c (_initialize_core_rs6000): Remove setting of xcoff_relocate_symtab_hook, no longer needed. * xcoffsolib.c (solib_info, sharedlibrary_command): Remove xcoff_relocate_symtab_hook indirection, call xcoff_relocate_symtab directly, as xcoffsolib.c is now compiled in native AIX configurations only. * Makefile.in: Update dependencies for rs6000-tdep.o, rs6000-nat.o and xcoffsolib.o.
