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.

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.

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.

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.
* config/sh/tm-linux.h: New file. Include generic tm-linux.h,
plus tm-sh.h, then define SVR4_FETCH_LINK_MAP_OFFSETS to use
the sh target function instead of the default link map offsets.
* config/sh/sh.mt: Add solib.o and solib-svr4.o to TDEPFILES.
Use sh/tm-linux.h instead of sh/tm-sh.h.
* sh-tdep.c (sh_linux_svr4_fetch_link_map_offsets):
New function. Construct target-specific link map offsets.
* i386-linux-tdep.c (i386_linux_svr4_fetch_link_map_offsets:
New function. Construct target-specific link map offsets.
* config/i386/tm-linux.h: Use above function instead of default.
2000-10-30 Michael Snyder <msnyder@cleaver.cygnus.com>
* config/i386/tm-linux.h: Remove definition of SVR4_SHARED_LIBS,
and inclusion of solib.h. Move up into ../tm-linux.h.
config/tm-linux.h: Define SVR4_SHARED_LIBS, include solib.h.
* ax-gdb.c (gen_struct_ref): while generating data code, cases of
"collect p1->p2->data" where not covered if p2 is a 'typedefed'
type. this simple fix should forward the type pointer to the real
type.
set_gdbarch_from_file): Fix spelling error.
* v850-tdep.c (v850_target_architecture_hook): Likewise.
* gdbarch.sh: Fix spelling errors in comment.
* gdbarch.c, gdbarch.h: Regenerate.
* ppcnbsd-nat.c (fetch_core_registers, fetch_inferior_registers,
store_inferior_registers): Support older NetBSD/powerpc systems
from before fp reg support was added. Adapt to register number
changes caused when powerpc target was multi-arched.
* stabsread.c (define_symbol): Update comment.
2000-10-26 Pierre Muller <muller@ics.u-strasbg.fr>
* stabsread.c (define_symbol): Set the type_name of the type
of the new symbol to the symbol name for type symbol, if the
language is Pascal.
* symtab.h (SYMBOL_INIT_DEMANGLED_NAME): Initialize the symbol language to auto
instead of unknown, so it will try to demangle the symbol.
* symtab.h (OPNAME_PREFIX_P): Change operator prefix to correct value.
* symtab.c (gdb_mangle_name): Properly handle C++ operators.
* config/gdbserver.exp: Rewritten from the ground up, to make it
compatible with the current dejagnu tree, and to make it work with
the new "gdbserver" in libremote.
* lib/gdb.exp (gdb_skip_float_test): New proc. Skip test if
no floating point support.
(gdb_skip_stdio_test): New proc. Skip test if no stdio support.
* gdb.base/call-ar-st.exp: Use above procs to skip tests.
* gdb.base/call-rt-st.exp: Ditto.

Adjust call_dummy_breakpoint_offset, so that `finish' after a stop
in a call dummy works.
(sparc_gdbarch_init): Fix setting of pc_in_call_dummy, it depends
on SPARC32/64_CALL_DUMMY_ON_STACK, not DO_CALL_DUMMY_ON_STACK.
* remote.c (putpkt_binary): Call read_frame, not getpkt. Log message.
(read_frame): Do not call error() on communication error when
reading checksum, but return failure instead and log message.
* varobj.c (type_changeable): Arrays are not changeable.
Trying to check for updates was causing an error if the array lived
in a register as gdb value_equal() cannot handle that case yet.
* varobj.c (varobj_update): Prevent uninitialized error code to be
returned on type_changed. Also, prevent value_equal() to be called
for the types we do not want to test for updates.
From Grant Edwards <grante@visi.com>
This keeps the GUI alive while running an RDI target and lets the
STOP button be used to stop the target.
* remote-rdi.c (arm_rdi_stop): New function. Implements target_stop.

waits while target is executing. Initialize and reset stop_request.

From Daniel Berlin <dberlin@redhat.com> :
* symtab.h (SYMBOL_INIT_DEMANGLED_NAME): Initialize the symbol
language to auto instead of unknown, so it will try to demangle
the symbol.
* symtab.h (OPNAME_PREFIX_P): Change operator prefix to correct value.

* symtab.c (lookup_symbol_aux): New function. Renamed from
lookup_symbol. Move code to do demangling/case sensitivity to
lookup_symbol().
(lookup_symbol): Now wrapper for lookup_symbol_aux, so we can
perform case sensitivity/demangling without leaking memory. Move
code to do demangling/case sensitivity from old_lookup_symbol to
here.
(lookup_partial_symbol): Use SYMBOL_SOURCE_NAME instead of
SYMBOL_NAME.
(lookup_block_symbol): Use SYMBOL_SOURCE_NAME instead of
SYMBOL_NAME. Don't do linear search in case of C++.
* symfile.c (compare_symbols): Use SYMBOL_SOURCE_NAME instead of
SYMBOL_NAME.
(compare_psymbols): Same here.
for call dummy instead of accessing stop_stack_dummy, which does
not work if we `return' from a stop in a call dummy.
(rs6000_gdbarch_init): Use generic_save_dummy_frame_tos for
dummy_frame_tos function to make PC_IN_CALL_DUMMY work.
OLD_CANNOT_FETCH_REGISTER): New definitions for accessible registers
when accessing the registers via the U area.
(fetch_register, store_register): Use them.
(cannot_fetch_register, cannot_store_register): New functions,
all registers should be accessible if we have GETREGS support.
