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.
is not defined.
(read_register_pid): Only needed when TARGET_READ_PC is not
defined.
* hppa-tdep.c (frame_saved_pc): Remove prototype.
* infptrace.c (udot_info): Prototype when CHILD_XFER_MEMORY is
not defined.
* config/xm-aix4.h (aix_resizewindow): Convert old style decl
to prototype.
* xcoffsolib.c (command.h): Include for needed prototypes.
* config/rs6000/rs6000.mh (NATDEPFILES): Move xcoffread.o ...
* config/rs6000/rs6000.mt (TDEPFILES): ... to here
* xcoffsolib.c (xcoff_relocate_symtab_hook): Define and initialize.
(solib_info): Call xcoff_relocate_symtab via the hook.
(sharedlibrary_command): Ditto.
* xcoffread.c: Remove all FAKING_RS6000 comments and defines.
(xcoff_add_toc_to_loadinfo_hook): Define and initialize here.
(xcoff_init_loadinfo_hook): Define and initialize here.
(scan_xcoff_symtab): Call xcoff_add_toc_to_loadinfo via the hook.
(xcoff_initial_scan): Call xcoff_init_loadinfo via the hook.
* xcoffsolib.h (xcoff_relocate_symtab_hook): Declare extern func.
* rs6000-tdep.c (_initialize_rs6000_tdep): Add initializations
of xcoff_add_toc_to_loadinfo_hook and xcoff_init_loadinfo_hook.
* rs6000-nat.c (_initialize_core_rs6000): Add initialization
of xcoff_relocate_symtab_hook.
* xcoffsolib.c (sharedlibrary_command): New command.
* xcoffsolib.c (solib_info): Call xcoff_relocate_symtab.
* xcoffsolib.c: Miscellaneous cleanups.
* partial-stab.h: Ignore symbol descriptor '-' (for local
variables with negative type numbers) without complaint.
* rs6000-nat.c (vmap_ldinfo): Use bfd_stat rather than our own
local emulation thereof. Remove unused variable ostart.
Change all references to stdout/stderr to gdb_stdout/gdb_stderr.
Replace all calls to stdio output functions with calls to
corresponding _unfiltered functions (`fprintf_unfiltered')
Replaced calls to fopen for output to gdb_fopen.
Added sufficient goo to utils.c and defs.h to make the above work.
The net effect is that stdio output functions are only directly used
in utils.c. Elsewhere, the _unfiltered and _filtered functions and
GDB_FILE type are used.
In the near future, GDB_FILE will stop being equivalant to FILE.
The semantics of some commands has changed in a very subtle way:
called in the right context, they may cause new occurences of
prompt_for_continue() behavior. The testsuite doesn't notice anything
like this, though.
Please respect this change by not reintroducing stdio output
dependencies in the main body of gdb code. All output from commands
should go to a GDB_FILE.
Target-specific code can still use stdio directly to communicate with
targets.
* xcoffread.c (retrieve_tracebackinfo): Move assignment out
of while condition.
* xcoffread.c (enter_line_range): complain() on bad endoffset.
xcoffread.c: Doc fixes.
Tue Mar 9 09:56:12 1993 Jim Kingdon (kingdon@cygnus.com)
* tm-rs6000.h (CORE_NEEDS_RELOCATION): Just call xcoff_relocate_core.
xcoffexec.c (xcoff_relocate_core): New function.
(text_adjustment): Removed.
(add_vmap): Return the vmap.
rs6000-tdep.c (add_text_to_loadinfo): No longer static.
Fri Mar 5 05:22:46 1993 Jim Kingdon (kingdon@cygnus.com)
* xcoffsolib.h: Add objfile member to struct vmap.
xcoff{exec,solib}.c: Use it, not lookup_objfile_bfd.
xcoffexec.c (add_vmap): Allocate objfiles here.
