SOLIB_SYMBOLS_MANUAL code, cleanup of AIX shared library handling code.

if symbols are not yet loaded.

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.

only.

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.

and xcoffsolib.o.
* config/tc-ia64.c (struct unw_rec_list): Add slot_frag field.

section->contents set and location not equal to contents plus offset.

reference.
* obj.h (format_ops): Add the frob_file_before_adjust field.

value_assign which can longjump. Do not change varobj value if
assign fails.
From Steven Johnson <sbjohnson@ozemail.com.au>:
This set of changes add "hookpost-" as an expansion on the original
hooking of commands to GDB. A Hook may now be run "AFTER" execution of
a command as well as before.
* command.h (struct cmd_list_element): Changed elements hook and hookee
to hook_pre and hookee_pre respectively. Added hook_post and hookee_post
for the post hook command operation. Added hook_in so that an executing
hook can be flagged to prevent recursion.
* command.c (add_cmd): Changed initilization of cmd_list_element to
reflect above changes.
(delete_cmd): Remove both pre and post hooks.
(help_cmd): Notify that the command has pre and/or post hooks.
* infrun.c (normal_stop): Change references to hook_pre from hook.
* top.c (execute_command): Run both pre and post hooks.
(define_command): Allow definition of both pre and post hooks.
The definition of pre-hooks is done as before, with the "hook-"
prefix for backward compatibility.
t_double_values to initialize the FPU before inferior calls are made.
* gdb.base/callfuncs.exp: Test for register preservation after calling
inferior functions. Add tests for continuining, finishing and
returning from a stop in a call dummy.
* elf32-arm.h (elf32_arm_merge_private_bfd_data): Always permit
BFDs containing no sections to be merged, regardless of their flags.
2000-11-04 Philip Blundell <philb@gnu.org>
* elf32-arm.h (elf32_arm_relocate_section): Suppress error message
if a relocation for an undefined symbol also results in an
overflow.
* configure.in: Recognize alpha-*-freebsd*.
* configure: Regenerate.
I had this in my local tree for along time and had gotten approval for this
on Mon, 22 May 2000 15:45:01 -0700 but somehow managed to never commit it.

if calloc fails.
(htab_create): Update comment to cover memory allocation.
(htab_try_create): New.
