instructions as function_frame_info does. Expand special case of
st r31,-4(r1) to be st r31,NUM(r1), since gcc can generate offsets
other than -4.
(pop_frame): Add 4 rather than sizeof (int) to avoid host

output. Move "maint info" from class info to class maintenance,
and improve text.

function so it will not be seen as a global help topic. FIXME,
it should be possible to set these attributes independently.
* core.c (core_command): Make nicer error message for no core support.
* dbxread.c (read_dbx_symtab): Use L_SET as bfd_seek arg.

objfile. dbfoff and lnoffset are file_ptr's now.

elfstab_build_psymtabs prototypes.
* xcoffread.c (init_stringtab, init_lineno, xcoff_symfile_read):
Use file_ptr offsets. bfd_seeks use L_SET.

stepping.
* mips-tdep.c (mips_pop_frame): Rewrite handling of
linked_proc_info so that it properly deallocates the appropriate
item after it is done with it instead of before.
* Don't pass bogus frame pointer to create_new_frame(). Just
leave it as zero so that lower level code will figure out the
correct value.
* xm-hppah.h: if __STDC__ is not defined, define
HPPA_COMPILER_BUG.
symtab.c (decode_line_1): avoid a bug in the HP9000/700 native
compiler; see the comment in the file.
Here's the comment from the file:
/* FIXME: The native HP 9000/700 compiler has a bug which appears
when optimizing this file with target i960-vxworks. I haven't
been able to construct a simple test case. The problem is that
in the second call to SKIP_PROLOGUE below, the compiler somehow
does not realize that the statement val = find_pc_line (...) will
change the values of the fields of val. It extracts the elements
into registers at the top of the block, and does not update the
registers after the call to find_pc_line. You can check this by
inserting a printf at the end of find_pc_line to show what values
it is returning for val.pc and val.end and another printf after
the call to see what values the function actually got (remember,
this is compiling with cc -O, with this patch removed). You can
also examine the assembly listing: search for the second call to
skip_prologue; the LDO statement before the next call to
find_pc_line loads the address of the structure which
find_pc_line will return; if there is a LDW just before the LDO,
which fetches an element of the structure, then the compiler
still has the bug. */
* nindy-share/nindy.c (coffstrip): Use that pathname, instead of searching for
a "bfd_strip" program. Also, fixed up arguments passed to that program.
* tm-nindy960.h (ADDITIONAL_OPTIONS): Use "-ser" rather than "-r", which is now
used for something else. Rewrite description of associated parameters to match
how gdb does it now.
(ADDITIONAL_OPTION_HELP): Fix message accordingly.
* m68k-pinsn.c (print_insn_arg): Handle new "`" operand type.
Specifically, the calling of inferiors methods is improved.
* value.h: New macros METHOD_PTR_IS_VIRTUAL,
METHOD_PTR_FROM_VOFFSET, METHOD_PTR_TO_VOFFSET to partially
hide the implementation details of pointer-to-method objects.
How to tell if the pointer points to a virtual method is
still very dependent on the particular compiler, but this
should make it easier to find the places to change.
* eval.c (evaluate_subexp [case OP_FUNCALL]), valprint.c
(val_print [case TYPE_CODE_PTR]): Use the new METHOD_PTR_*
macros, instead of a hard-wired-in code that incorrectly
assumed a no-longerused representation of pointer-to-method
values. And otherwise fix the relevant bit-rotted code.
* valprint.c (type_print_base [case TYPE_CODE_STRUCT]):
If there are both fields and methods, put a space between.
* stabsread.c (read_struct_type): Fix bug in handling of
GNU C++ anonymous type (indicated by CPLUS_MARKER followed
by '_'). (It used to prematurely exit the loop reading in
the fields, so it would think it should start reading
methods while still in the fields. This could crash gdb
given a gcc that can emit nested type information.)
* valops.c (search_struct_method): Pass 'this' value by
reference instead of by value. This provides a more
consistent interface through a recursive search where the
"bottom" functions may need to adjust offsets (due to multiple
inheritance).
* valops.c, value.h, values.c: Pass extra parameters to
value_fn_field and value_virtual_fn_field so we can
correctly adjust offset for multiple inheritance.
* eval.c (evaluate_subexp [case OP_FUNCALL]): Simplify
virtual function calls by using value_virtual_fn_field().
* values.c: New function baseclass_offset, derived from
baseclass_addr (which perhaps can be made obsolete?).
It returns an offset rather than an address. This is a
cleaner interface since it doesn't mess around allocating
new values.
* valops.c (search_struct_method): Use baseclass_offset
rather than baseclass_addr.
* remote-udi.c (udi_resume): Clean up.
* (udi_wait): Rewrite, leave out bugs.
* Add debugging code to print out all register fetches and stores.
* Straighten out target_ops.
* tm-29k.h (DUMMY_FRAME_RSIZE): Pad out to doubleword.
* remote-udi.c (udi_create_inferior): run with no arguments should
not pass the program name as an argument, since the UDI code
already handles that.
(udi_load): get the symbols from prog_name, not arg_string (the
load command should really use arg_string as the program name, not
prog_name, but at least the run command works now).
* am29k-tdep.c (_initialize_29k): Make it possible for the
user to set and query the address where function calls into the
inferior write a small scratch routine. `set call_scratch_address'
* inferior.h (PC_IN_CALL_DUMMY): Fix fencepost error.
* remote.c (remote_prepare_to_store): Only fetch regs if they are
not already cached validly.
* infptrace.c: remove #ifdef USG from around include ptrace.h.

(ATTACH_DETACH, FETCH_INFERIOR_REGISTERS): moved to nm-rs6000.h.
* config/rs6000.mh (XDEPFILES): removed rs6000-xdep.o.
infptrace.o and inftarg.o move to NATDEPFIES.
(NAT_FILE, NATDEPFILES): new macro for native support.
* config/sun3os3.mh, config/sun3os4.mh (NAT_FILE, NATDEPFILES):
new macros for native support.
(XDEPFILES): moved infptrace.o and inftarg.o to NATDEPFILES,
removed sun3-xdep.o.

field. Add new `hook', `hookee', and `cmd_pointer' fields.
* command.c (add_cmd): Initialize new fields, elim old.
(add_alias_cmd): Clone new fields.
(delete_cmd): Un-hook hookee if we're deleting hook.
(help_cmd): Tell user the command is hooked, if it is.
(lookup_cmd_1): Abbreviations return the original command
instead of themselves, so that hooks on the original cmd will be
run.
* defs.h (enum command_class): Add class_pseudo and comments.
* gdbcmd.h (execute_user_command): Add prototype.
* infrun.c (normal_stop): If the stop command is hooked,
run the hook whenever we stop.

* infptrace.c: include nm.h rather than nat.h.
* Makefile.in (TSOBS): removed corelow.o.

Briefly explain MIPS stacks in GDB.
Rich and I believe the "real problem" was that both single_step

followed by pointer into string being demangled, followed by
pointer to the string where the result is being stored, followed

and trigger a coredump.
* symtab.c (lookup_symbol, lookup_demangled_block_symbol,
lookup_demangled_partial_symbol,): Ask demangle_and_match to
match on complete demanglings, including argument lists for member
functions, rather than just accepting the first demangling that
matches the class and function name.

portion of the AT_comp_dir attribute string. Gdb doesn't know
what to do with them (FIXME).
