to automatically dereference a function pointer for printing
if necessary.
(c_val_print): Use print_function_pointer_address when printing
function pointer addresses.
(sources_info): Replace use of no_symtab_msg with the string
itself.
* linespec.c (no_symtab_msg): Remove declaration.
(decode_line_1): Replace uses of no_symtab_msg with the string
itself.
* regcache.c (read_register_bytes): Failing to set register_valid
is not necessarily an error, if the register is a pseudo-register.
Some pseudo-registers are never marked as valid, so that they will
be read anew every time. Determining if a pseudo-register is valid
(or should be marked invalid) may be difficult, whereas just
recomputing it may be cheap.
step_over_calls.
* infcmd.c (step_over_calls): Change definition.
(step_1): Use new enum values in relation to step_over_calls.
(step_once): Ditto.
(until_next_command): Ditto.
* infrun.c (clear_proceed_status): Ditto.
(handle_inferior_event): Ditto.
* inferior.h (step_stop_if_no_debug): New variable.
* infrun.c (step_stop_if_no_debug): Declare.
(handle_inferior_event): Stop the step command if we entered a function without
line info.
(_initialize_infrun): New command 'set step-mode' to control the step command.
* infcmd.c (step_once): Switch to stepi mode if there is no line info
(and switching is enabled).
* target.c (do_xfer_memory): Only perform a single memory transfer
instead of iterating to tranfer the entire region. Higher layers
are expected to call this function multiple times for partial
transfers.
(target_xfer_memory_partial): Remove unused local variables.
2000-11-10 Nick Duffek <nsd@redhat.com>
* target.c (target_xfer_memory_partial): Return bytes transferred
instead of 0.
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.
* wrapper.c (gdb_value_assign): New function. Longjump-free
version of value_assign.
(wrap_value_assign): New function. Wrapper for value_assign.
* wrapper.h: Add declaration for the above.
* varobj.c (varobj_set_value): Use gdb_value_assign, not
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.
* 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.
