* exec.c (ignore): Return 0.
* stack.c (return_command): Fetch lazy value directly, not via
VALUE_CONTENTS, to avoid "value computed is not used".
* inflow.c (new_tty): Move osigttou inside #if.
* remote.c (remote_fetch_registers): If remote reply is short, just
note that fact and keep going (reading extra registers as all bits 0).
(remote_store_registers): Send number of registers that were found
by remote_fetch_registers.
* m68k-tdep.c, config/m68k/tm-m68k.h, config/m68k/tm-*.h: Remove
HAVE_68881. Define CANNOT_STORE_REGISTER if ptrace() can't write
floating registers.

Include sys/types.h regardless of USG.
* configure.in: Fix typo (delta88r4 -> delta88v4).

to make this work on SVR4 before SVR4 had its own configuration,
and it breaks SVR3.

* config/m88k/xm-m88k.h: New file, with HOST_BYTE_ORDER,
MAKEVA_END and MAKEVA_ARG.

Revise comments re linetable sorting.
* buildsym.c (compare_line_numbers): Sort by pc, not by line.
* coffread.c: Tell end_symtab to sort the line table.
* coffread.c: Re-work a lot of the coff-specific stuff to use stuff
in buildsym.c. This includes coff_finish_block, coff_context_stack,
coff_local_symbols, coff_file_symbols, coff_global_symbols,
coff_end_symtab and coff_add_symbol_to_list.
(read_enum_type): Deal with it now that we have a "struct pending"
not a "struct coff_pending".
* buildsym.c (end_symtab): Don't realloc subfile->linetable.
is unambigous. Patch from ptf@delcam.co.uk (Paul Flinders).
* mipsread.c (ecoff_symfile_info): New struct to hold the global
pending_list.
* mipsread.c (mipscoff_symfile_init, parse_partial_symbols):
Allocate the global pending list and link it to the objfile.
* mipsread.c (is_pending_symbol, add_pending): Use global pending
list from objfile. Allocate pending list entries from the
psymbol_obstack.
* mipsread.c (free_pending): Remove. The pending list is now
freed when the psymbol_obstack is freed.
* mipsread.c (psymtab_to_symtab1): Remove pending list allocation,
the global pending list is used now.
* mipsread.c (parse_partial_symbols): Skip only the first
file indirect entry when building the dependency list.
show < 0. The only case where we had been distinguishing is that
show = 0 used to print "struct " or "enum " instead of
"struct {...}" or "enum {...}" which seems clearly wrong.
was empty and thrown away.
* mipsread.c (parse_partial_symbols): Do not add empty psymtabs to
dependency list, skip self dependencies.
* mipsread.c (parse_fdr): Removed, obsolete.
* mipsread.c (parse_lines): Check for cbLine being zero, not
cbLineOffset.
* mipsread.c (struct symloc): Add pst_language.
* mipsread.c (parse_partial_symbols): Set up proper language for header
files, save it in pst_language for psymtab_to_symtab_1.
* mipsread.c (psymtab_to_symtab_1): Use pst_language.
besides the dummy, return 1 rather than calling error().
Let caller print the error message. Remove name argument.
* valops.c (call_function_by_hand): Deal with changes to calling
sequence of run_stack_dummy. Discard restore_inferior_status cleanup
if run_stack_dummy returns 1.
support to use LOC_BASEREG rather than SYMBOL_BASEREG_VALID.
* dwarfread.c: Use LOC_BASEREG where appropriate.
* Various: Support LOC_BASEREG and LOC_BASEREG_ARG.
* stabsread.h: Group together dbxread.c functions.
Move elfstab_build_psymtabs here from symfile.h.
Declare pastab_build_psymtabs.
* elfread.c, paread.c: Include stabsread.h (for stabsread_new_init
declaration, etc).
(double_scan, multi_scan): generalize double_scan into a scan
for multiple patterns. Rename to multi_scan.
(bug_wait, bug_write_inferior_memory): adapt to use the new
multi_scan in order to catch and represent target bus errors.
(bug_scan): currently unused, so comment out.
(bug_quiet): removed. Replaced with a standard user settable boolean.
Set language for psymtab and symtab.
* mipsread.c (new_symbol): Set language and initialize demangled
name for symbol.
* symmisc.c (print_symbol): Use SYMBOL_SOURCE_NAME when printing
the symbol type.
* symtab.c (decode_line_1): Inhibit coredumps with cfront executables.
it conditionalized on 4.3 vs. 4.4.
* config/m68k/nm-hp300bsd.h: Move REGISTER_U_ADDR out of 4.3 and
4.4 sections; it was identical and now works for 4.4.
non-existent files nm-delta.h, etc.
* config/m68k/tm-delta68.h: Define CANNOT_STORE_REGISTER.
* delta68-nat.c: Add "[0]" in offsetof argument.
* delta68-nat.c (_initialize_kernel_u_addr): Don't try to set up
nl with initializer, just assign to it. Check n_scnum field on
return.
(FP_REGNUM): define in terms of SP_REGNUM
rather than by absolute number. Also clearly comment that this
is a convenient lie in order to decrease future confusion.
(ACTUAL_FP_REGNUM): new macro for FP.
(FRAME_CHAIN_VALID): removed. Standard default works fine.
* m88k-tdep.c (frame_chain_valid): redundant, so removed.
(NEXT_PROLOGUE_INSN): removed unused fourth arg, fixed all
callers.
(read_next_frame_reg): declare static.
(examine_prologue): removed unused variabel insn2, rename insn1
to insn, rewrote comment about finding fp, sp, etc. set frame_fp
based on ACTUAL_FP_REGNUM rather than FP_REGNUM which is
actually a scammed alias for SP_REGNUM on m88k.
the saved pc from sigcontext on the stack for BSD signal handling.
* config/i386/tm-i386bsd.h (SIGTRAMP_START, SIGTRAMP_END, FRAME_CHAIN,
FRAMELESS_FUNCTION_INVOCATION, FRAME_SAVED_PC, SIGCONTEXT_PC_OFFSET):
Define to make backtracing through sigtramp work.
* config/vax/tm-vax.h (SIGTRAMP_START, SIGTRAMP_END, TARGET_UPAGES,
FRAME_SAVED_PC, SIGCONTEXT_PC_OFFSET): Ditto.
Use the function name when calling IN_SIGTRAMP.
* config/m68k/tm-m68k.h (SIG_PC_FP_OFFSET, SIG_SP_FP_OFFSET):
Define for correct handling of bachtraces through _sigtramp.
* m68k-tdep.c (m68k_find_saved_regs): Adjust saved sp for fake
sigtramp frames.
* mipsread.c (parse_type): Handle corrupt TIR info with complaint
instead of core dump.
* mipsread.c (parse_partial_symbols): Put static symbols into the
mimimal symbol table, use proper mst_types for all minimal symbols.
* stack.c (frame_info, print_frame_info): Use the starting source
line number on a line boundary if backtracing through sigtramp.
