* doc/gdbint.texinfo: Update GET_LONGJMP_TARGET, L_SET doc.
* irix4-nat.c, mips-nat.c (JB_ELEMENT_SIZE, get_longjmp_target):
Move from mips-tdep.c and tm-{irix3,mips}.h.
* mips-nat.c: Remove a bunch of code that was ifdef'd out of
native MIPS ports.
* nm-irix3.h, nm-mips.h (GET_LONGJMP_TARGET): Move from tm-irix3.h
and tm-mips.h.
* ultra3-nat.c (register_addr): Move from ultra3-xdep.c.
(fetch_core_registers): Fix bfd_seek arguments.
(OBS): Put version.o first, so Makefile rebuild happens early.
* command.h: Publicize prototype for not_just_help_class_command.
* command.c: Remove proto.
* maint.c: Mark "mt" as an abbrev, to avoid duplicated help
output. Move "maint info" from class info to class maintenance,
and improve text.
* infrun.c: Move "stop" to class_obscure, and give it a
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.
(elfstab_build_psymtabs): staboffset and stabstroffset args are
file_ptr's.
* dwarfread.c (struct dwfinfo): Convert dbfoff, lnfoff to file_ptr.
(scan_compilation_units): Punt unused filename arg. dbfoff,
lnoffset, and curlnoffset are file_ptr's now.
(dwarf_build_psymtabs): Drop desc and filename args; use
objfile. dbfoff and lnoffset are file_ptr's now.
(read_ofile_symtab): foffset is now file_ptr. Use L_SET in bfd_seek.
* elfread.c (struct elfinfo): dboffset and lnoffset are file_ptr's.
(elf_symfile_read): Skip desc and filename args to
dwarf_build_psymtabs. Pass file_ptr's to elfstab_build_psymtabs.
* gdb-stabs.h: Use file_ptr rather than off_t.
* mipsread.c (fixup_symtab): f_ptr is a file_ptr. Re-enable
compile-time debug check that someone turned off as "unused".
(read_the_mips_symtab): st_filptr is a file_ptr. Fix bfd_seek call.
* symfile.h: Update dwarf_build_psymtabs and
elfstab_build_psymtabs prototypes.
* xcoffread.c (init_stringtab, init_lineno, xcoff_symfile_read):
Use file_ptr offsets. bfd_seeks use L_SET.
symbol. #define MIPS_EFI_SYMBOL_NAME instead. Use different
value so that demangler won't be invoked. This greatly speeds up
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.

removed sun3-xdep.o.
* xm-sun3.h (ATTACH_DETACH, FETCH_INFERIOR_REGISTERS): moved to
nm-sun3.h.

run.
* defs.h (enum command_class): Add class_pseudo and comments.

* main.c (execute_user_command): Code extracted from execute_command.
(execute_command): If hooked, run the hook before the command.

* doc/gdb.texinfo: Document command hooks.
* Makefile.in (VERSION): Roll to 4.6.7.
* config/sun4os4.mh: Remove dup inftarg.o from NATDEPFILES.
* infrun.c (breakpoints_inserted): Make it static again.

* infptrace.c: include nm.h rather than nat.h.
* Makefile.in (TSOBS): removed corelow.o.
* infptrace.c: included nat.h.
* nat-trash.h: temporary header file. This should be removed once
all hosts have the native/host/target split.

* dbxread.c, partial-stab.h: Replace all #ifdef hp9000s800's with
GDB_TARGET_IS_HPPA's. This is a SERIOUS KLUDGE. The code needs to all
be ripped out and reimplemented right (see elfread.c).
* tm-hppa.h (GDB_TARGET_IS_HPPA): Define.

so, and what version.
ANSI compiler warnings.

operands to memory management instructions, from WRS.
Replace with simple default to C before processing any init

init files or executables, or expression parsing fails.
symfile.c. Fixup places where command files are processed to
be consistent in setting a default language if none has been
previously set.
* symfile.c (set_initial_language): Add code moved from

* mips-tdep.c (init_extra_frame_info): Only clobber the `frame'
(FP) value in the frame_info struct if it is zero (as from top of
execution stack).
(setup_arbitrary_frame): Implement FRAME_SPECIFICATION_DYADIC.
* mips-xdep.c (fetch_inferior_registers): ZERO_REGNUM always
comes back as zero. So does FP_REGNUM, as a trigger for

the program counter set before INIT_EXTRA_FRAME_INFO is run.
(INIT_FRAME_PC): Defined to null.

(FRAME_SPECIFICATION_DYADIC): Ask for two args in frame command.
Briefly explain MIPS stacks in GDB.
Rich and I believe the "real problem" was that both single_step
and target_resume were issuing PT_CONTINUE calls. This would
cause the second PT_CONTINUE to sometimes fail because the process
was already running.
* infptrace.c (child_resume): Remove AIX_BUGGY_PTRACE_CALL kludge.
* infptrace.c (child_resume): Don't deal with NO_SINGLE_STEP
here; it is dealt with at a gdb-target-independent level.
* rs6000-tdep.c (single_step): Don't call ptrace, we are a
high toned routine. Fix return type to void.
before printing anything, and again afterward. Fix comments.

(full_filename): Don't prepend dirname if filename begins with /.
(breakpoint_notify, kernel_dispatch): Deal with DynamicLoad
messages properly!!
(getpty (NCR)): Lotsa bug fixes...
(kernel_dispatch (case StopRType)): Use kill() instead of
killpg() so we can deal with losing systems...
(wait_for_events): Work around NCR select() lossage. It doesn't
zero out readfds when select() returns zero.
(energize_initialize): Use I_SETSIG to get SIGIO interrupts. Use
getcwd() instead of getwd() (NCR getwd() seg faults).
(energize_wait): Use sigaction() for NCR. Their version of signal()
is unreliable by default.
places where we must notify kernel of where the given pc is.
(cplus_demangle): Put single-quotes around demangled names.
(energize_call_command): Call send_location() after doing up,
down, and frame commands.

* config/sun4.{mh,mt}: Remove (use identical sun4os4.*).
sub-variants of SunOS, e.g. sunos4* to match sunos4.1.1.

typedefs for C++ classes, structs, unions, and enumerations.
* dwarfread.c (scan_compilation_units): Call set_cu_language
to record language for current compilation unit.

for TAG_enumeration_types, rather than in add_partial_symbol.
* dwarfread.c (add_partial_symbol): Combine TAG_enumeration_type
case with class, struct, and union type cases, now that they are
the same. Remove tests for non-NULL name attributes, now done
by callers.
* gdbtypes.h (TYPE_CODE_CLASS): Add type for C++ classes, but
treat as alias for TYPE_CODE_STRUCT for now.
(supply_gregset, fill_gregset, supply_fpregset, fill_fpregset):
Use "regi" for local indexing through register numbers, reserving
"regno" for the name of a specific register passed as an input
parameter. Fix bug propagated through all versions that sometimes
used regno as an index when it should have been regi, thus using
-1 as an index in some cases.

* Makefile.in: Remove demangler stuff.
* Makefile.in (depend): Pass -I../readline (needed for main.c).
* demangle.c (_initialize_demangler): Tell demangler which
CPLUS_MARKER to assume.
follow the consistent pattern of struct work_stuff pointer first,
followed by pointer into string being demangled, followed by
pointer to the string where the result is being stored, followed
by other args. Also generally replace most variables of name
"type" with "mangled" for consistency. They all pointed to the
same string but half were one name and half the other.

* cplus-dem.c (demangle_qualified): Rewrite to clean up and allow
use whenever a qualified name is being demangled.

read_range_type): Use TYPE_ALLOC.
symtab if one is not currently selected.
* utils.c (query): Call wrap_here before building the output
query string, to turn off wrapping and flush any buffered output.
Otherwise our query may end up in the wrap buffer and never be
seen by the user.
* eval.c (evaluate_subexp): Report error when attempting to
evaluate subscript for types without a target type, rather
than dumping core by using the NULL pointer.
* symfile.c (symbol_file_command): Forget current_source_symtab
and current_source_line when discarding symbol table.
work. (remote_wait): Change 'T' message parser to deal with new
improved format which allows stub to send an arbitrary bunch of
registers.
* sparc-stub.c: General cleanups. (trap_low, handle_exception):
make all this re-entrant by storing all state on the stack. Clean
up memory error trapping. (computeSignal, set_debug_traps):
make it all table driven. Make a start at a baud rate setting command.
* remote-vx.c: redefine malloc to avoid buggy declaration on
RS/6000 <rpc/types.h>.
xm-rs6000.h: include <sys/select.h> to define fd_set for
<rpc/svc.h> on RS/6000.

* Makefile.in: added FLAGS_TO_PASS variable, and passed it to
recursive invocations of make. Always create installation
directories.
application, and it will speak GDB remote protocol!
* remote.c (remote_wait): Change 'T' (expedited reply) message to
deal with arbitrary registers. Needed for sparc-stub,
use throughout, in place of compile time constant CPLUS_MARKER.
* cplus-dem.c (ARM_VTABLE_STRING, ARM_VTABLE_STRLEN): Add.
* cplus-dem.c (cfront_special): New function, as suggested
by pfieland@stratus.com.
* cplus-dem.c (forget_types): New function.
* cplus-dem.c (cplus_demangle): Call gnu_special, moved from
demangle_prefix().
* cplus-dem.c (mop_up): Call forget_types().
* cplus-dem.c (AUTO_DEMANGLING, GNU_DEMANGLING, LUCID_DEMANGLING):
Use throughout, instead of checking current_demangling_style.
* cplus-dem.c (demangle_signature): When finding an explicit
start of function args, forget all remembered types for
lucid/cfront style demangling.
* cplus-dem.c (demangle_prefix): In a sequence of two or more
underbar characters, use last pair as the delimiter. Hoist
gnu_special() call up to cplus_demangle(). Call cfront_special()
when appropriate.
* cplus-dem.c (cplus_special): Fix virtual table name demangling
for inherited classes.
* cplus-dem.c (demangle_args): Document quirks of numbered
references to previously seen types.
* dbxread.c (read_ofile_symtab, process_one_symbol):
Use AUTO_DEMANGLING rather than explicitly checking
current_demangling_style.
* demangle.h: Add some comments.
* demangle.h (AUTO_DEMANGLING, GNU_DEMANGLING, LUCID_DEMANGLING,
CFRONT_DEMANGLING): New macros.
* dwarfread.c (LCC_PRODUCER): Remove trailing space, which is
not found in the actual producer string produced by lcc.
* dwarfread.c (handle_producer): Use AUTO_DEMANGLING rather
than explicitly checking current_demangling_style.
disable_longjmp_breakpoint, set_longjmp_resume_breakpoint):
Check for duplicate breakpoints at the same address. Bug report
and preliminary fix from Dave Morrison, <drmorris@us.oracle.com>.
NULL under non-error conditions.
* dwarfread.c (read_file_scope): Guard against dereferencing NULL
returned from end_symtab for empty compilation units.
* am29k-tdep.c: Lint from DECstation compiler.
* mem-break.c: Restore test of BREAKPOINT size that Fred removed.
As the man page says, "Sometimes you just can't get lint to shut
up". That doesn't mean you should blow away the code it won't
shut up about.
* mips-xdep.c: Revise stubbing-out of code until Rich cleans
it up over the next few weeks. Make mips x 29k build.
* tm-29k.h (CALL_DUMMY): Make it work on cross-endian hosts.
(FIX_CALL_DUMMY): Comment in the patching of the breakpoint,
but leave it as a comment because the breakpoint instruction
is not easily accessible at this moment (it's static, and if
we define one here, it goes into every file compiled).
* dwarfread.c (scan_partial_symbols): Skip over DIE's within
function scopes when building partial symbol tables.
* objfiles.c (open_existing_mapped_file): Make it clear in
warning message that out of date mapped files are ignored.
* symtab.c (lookup_symtab_1, lookup_symbol): Print compilation
unit source file name in error message.
* dwarfread.c (struct_type): In absence of AT_byte_size for
bitfield, use size of object of member's type for the size of
the anonymous object containing the bit field.
* dwarfread.c (completedieinfo): Set has_at_byte_size when
an AT_byte_size attribute is seen.
* mipsread.c (psymtab_to_symtab_1): Fix misspelled cast to
union aux_ext (was aux_ent).
* i386-pinsn.c (print_insn): Cast 2'nd arg to read_memory from
unsigned char* to char*, for Lucid compiler.
* i386-tdep.c (codestream_fill): Fix cast of 2'nd arg to read_memory
to be correct type (from unsigned char* to char*).
* valprint.c (type_print_derivation_info): Minor tweak to placement
of commas in derived class printing.
* xcoffread.c (builtin_type): Fix misspelling in fatal message.
* serial.c (find_source_lines): if LSEEK_NOT_LINEAR is defined
then work out the lseek positions of newlines by running through
the file and `tell'ing. This makes source file listing work on
OS's where the relationship between physical position in file and
canonical position is indeterminate, eg VMS and DOS.
