/* The vmap struct is used to describe the virtual address space of
|
|
|
|
the target we are manipulating. The first entry is always the "exec"
|
|
|
|
file. Subsequent entries correspond to other objects that are
|
|
|
|
mapped into the address space of a process created from the "exec" file.
|
|
|
|
These are either in response to exec()ing the file, in which case all
|
|
|
|
shared libraries are loaded, or a "load" system call, followed by the
|
|
|
|
user's issuance of a "load" command. */

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.
