alpha and irix. The _sigtramp case has to be handled properly
in the tdep files if we have no ecoff debugging info.
* alpha-tdep.c (alpha_frame_saved_pc, alpha_frame_chain),
mips-tdep.c (mips_frame_saved_pc): Handle signal handler frames
without PC_REGNUM kludge.
* mdebugread.c (fixup_sigtramp), mips-tdep.c (read_next_frame_reg):
Clean up handling of mips sigtramp frames, improve comments.
* paread.c (pa_symtab_read): Update the "check_strange_names"
filter to match GCC's current output. Filter out section symbols
(which the HP linker sometimes puts in the wrong place).
* Makefile.in: Remove all references to sparcly-nat.c.
* Makefile.in (HFILES_NO_SRCDIR): Include dcache.h remote-utils.h
remote-sim.h directly, rather than via $(remote_utils_h). This avoids
duplicating serial.h and target.h.
* Makefile.in: Don't set M_INSTALL and M_UNINSTALL. These variables
are not used anywhere (a 5 Oct 1993 change removed the uses).
If the timeout is too big to fit in c_cc[VTIME], then do multiple reads
to achieve the desired timeout.
* serial.h (serial_t): Add field timeout_remaining.
with the old tm-m68k-em.h:
(GDBINIT_FILENAME, DEFAULT_PROMPT): Remove.
(HAVE_68881): Don't undefine; this #define is obsolete.
(REGISTER_NAMES): Don't muck with it; what tm-m68k.h has is fine.
Add FIXME regarding GET_LONGJMP_TARGET.
* remote-utils.c (usage): Fix message to be accurate and conform
more closely to normal conventions.
* remote-utils.c (gr_files_info): Have the exec_bfd test control
whether to show information about exec_bfd, and not control whether
to show information about device and speed.
* remote-utils.c (gr_open): If sr_get_device returns NULL, give
usage message, don't dump core.
* remote-bug.c (bug_write_memory): Use alloca, not GCC extension
for variable size array.
(bug_fetch_register, bug_store_register): Rename "value" to
"fpreg_buf" because some compilers don't like variables whose
names are the same as types.
(bug_store_register): Use a cast when converting char * to
unsigned char *.
full details on structure elements without names. This partially
reverts the changes of 1 Jul 1993 and 31 Aug 1993; I think this aspect
of those changes was accidental.
various miscellaneous things discovered in the process:
* printcmd.c, defs.h (print_address_numeric): New function.
* c-valprint.c (c_val_print), ch-valprint.c (chill_val_print)
breakpoint.c (describe_other_breakpoints, breakpoint_1, mention),
cp-valprint.c (cplus_print_value), infcmd.c (jump_command),
printcmd.c, stack.c, symfile.c, symmisc.c, valprint.c:
Use it.
* utils.c, defs.h (gdb_print_address): New function.
* expprint (dump_expression), gdbtypes.h: Use it.
* breakpoint.c (describe_other_breakpoints),
symmisc.c (dump_symtab, print_symbol):
Use filtered not unfiltered I/O.
(remove_breakpoints): Remove BREAKPOINT_DEBUG code. Might as well
just run gdb under a debugger for this (and it had problems with
printing addresses, how to print b->shadow, etc.).
* buildsym.c (make_blockvector), core.c (memory_error),
exec.c (print_section_info), maint.c (print_section_table),
mdebugread.c (parse_procedure), solib.c, source.c, symfile.c,
symmisc.c, symtab.c, valops.c, valprint.c, xcoffexec.c:
Add comments saying code is broken. Marked with "FIXME-32x64".
* dbxread.c (process_one_symbol), partial-stab.h (default),
remote-vx.c (vx_run_files_info):
Don't cast int being passed to local_hex_string.
* symmisc.c (print_symbol): Don't cast long being passed to %lx.
* symtab.h (general_symbol_info): Add comment about SYMBOL_VALUE
only being a long.
* symmisc.c (print_symbol): Print "offset" in message for LOC_ARG
and LOC_LOCAL.
* printcmd.c (print_address): Remove #if 0 code with ADDR_BITS_REMOVE.
* source.c: Include <sys/types.h> regardless of USG.
not OBJ_UNWIND_INFO. Assigning to a cast is a GCC-ism which
the HP compiler in ANSI mode doesn't like.
* main.c: When defaulting HAVE_SIGSETMASK based on USG, just do it
based on USG, rather than defining HAVE_SIGSETMASK to an expression
containing defined. This is for the HP compiler in ANSI mode.
passing them to print_387_status.
(print_387_status): Don't subtract top from 7 before using it.
* i387-tdep.c: Remove comment about AIX wanting "top" subtracted
from 7; the above explains it.
cleanup chain, not directly.
* ser-unix.c (wait_for) [HAVE_TERMIO, HAVE_TERMIOS]: Make a timeout
of -1 mean forever, like in the HAVE_SGTTY case. Warn if we are
munging the timeout due to the limited range of c_cc[VTIME].
* procfs.c (procfs_create_inferior), inftarg.c (child_create_inferior),
m3-nat.c (m3_create_inferior): Pass it.
* procfs.c: Remove ptrace function. It was declared in a way which
conflicted with the prototype in unistd.h on Solaris.
step_resume_breakpoint for IN_SIGTRAMP cases.
* infrun.c (wait_for_inferior), breakpoint.h (struct bpstat_what),
breakpoint.c (bpstat_what): Move step_resume from its own field of
the struct bpstat_what into the main_action. Make it override
other breakpoints. This is a conservative change in the sense
that before the step resume breakpoint was a breakpoint.c
breakpoint, hitting the step resume breakpoint overrode even
calling bpstat_stop_status.
in case execution was stopped in the called function.
* stack.c (print_frame_info, frame_info): If backtracing through
a call dummy, handle the starting source line number on a line
boundary like backtracing through sigtramp.
* sparc-tdep.c (sparc_frame_find_saved_regs): Get frame address
for call dummy frame right. Remove old test for dummy frame,
it has been unused at least since gdb-3.5.
* sparc-tdep.c (sparc_push_dummy_frame): Set return address register
of the dummy frame.
reserved fields to hold a stub unwind entry type. Fix typo.
(stub_unwind_entry): New structure for raw stub unwind entries.
(stub_unwind_types): The types of stubs we may encounter.
(UNWIND_ENTRY_SIZE, STUB_UNWIND_ENTRY_SIZE): New defines.
* hppa-tdep.c (rp_saved): Use additional information provided
by linker stub unwind descriptors.
(frameless_function_invocation): Likewise.
(frame_chain_valid): Likewise.
* paread.c (compare_unwind_entries): New function for sorting
unwind table entries.
(read_unwind_info): Rewrite to remove dependency on host endianness.
Read in data from the $UNWIND_END$ subspace which contains linker
stub unwind descriptors. Merge that data into the basic unwind
table.
checking. Fix overflow check to use unsigned LONGEST, not
unsigned int.
* c-exp.y (parse_number): Make it so that integer constants are
builtin_type_long_long if builtin_type_long isn't big enough or if
an "LL" suffix is used. Properly handle "UL" or "LU" suffixes.
is on, call find_pc_function rather than relying just on the minimal
symbols (probably only matters for symbol readers which don't put
statics in the minimal symbols, but changing this strikes me as
not conservative enough).
Initialize name_location in all cases.
If no symbol and no msymbol, don't print anything symbolic.
symtabs for variables as well as functions. Add `set print
fast-symbolic-addr' and default it to fast (the old way).
Print line numbers for data items as well as functions.
* symtab.c (find_addr_symbol): Return the symtab and the symbol
address, if a symbol is found (take two more args pointing to
where to store these results).
* symtab.h (find_addr_symbol): Add prototype.
compiler generated tag names.
* mdebugread.c (parse_type): Handle cross references to qualified
aggregate types.
* valops.c (value_struct_elt): Improve error message if the
address of a method is requested from an object instance.
* valops.c (search_struct_method): Make name_matched non-static
to get it initialized correctly.
partial_symbol): Shrink the storage sizes of symbols, by making
enums into 1-byte bitfields when compiled __GNUC__, moving all the
enums and small ints to the end of each struct to improve
alignment, and switching the section number from int to unsigned short.
to [0,0] rather than [0, end of first source file]. This avoids
problems with other parts of GDB looking for linetables in the
_globals_ symtab. Eliminate variables num_object_files and
first_object_file_end.
Fixes PR gdb/4072.
(pop_frame): Restore PC2 and LR0 from dummy frames.
(push_dummy_frame): Save PC2 and LR0 into dummy frames.
(setup_arbitrary_frame): Handle 3 args and set up real frames.
* config/a29k/tm-a29k.h (FRAME_NUM_ARGS): Update comments.
(DUMMY_FRAME_RSIZE): Add 2 longwords for PC2 and LR0.
(SETUP_ARBITRARY_FRAME): Define.
there.]
* sparc-tdep.c (sparc_pop_frame): Pop the fsr and csr (float and
coprocessor status regs) when popping a frame. This fixes
float exceptions that occur after calling inferior functions.
* sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
Read and write the fsr (float status register) to/from the child
process along with the float regs. Remove Peter Schauer's change
of May 24 '93, which has higher overhead and doesn't solve the
real problem (which was that FSR wasn't being set).
Read and write the fsr (float status register) to/from the child
process. This avoids random float exceptions when running under
GDB, and probably obsoletes Peter Schauer's change of May 24 '93
(which remains for safety).
stack overflow check isn't right after the register stack
adjustment instruction. Metaware R2.3u compiler moves other
things in front of it. This fix isn't perfect but is what's
running.
config/vax/tm-vax.h (CALL_DUMMY_BREAKPOINT_OFFSET): Define.
* mdebugread.c (parse_symbol): Handle enum sh.type produced by
DEC c89.
* mdebugread.c (add_line): Handle zero linenos produced by DEC c89.
printing to gdb_stderr.
* remote-udi.c (udi_kill): Don't close the connection, just set
inferior_pid to zero.
(udi_mourn): Call remove_breakpoints.
* remote-udi.c: Remove obsolete need_artificial_traps comment.
* target.c (store_waitstatus): Add CHILD_SPECIAL_WAITSTATUS hook.
* infrun.c (wait_for_inferior): Replace SIGTRAP_STOP_AFTER_LOAD with
code which looks for those two waitkinds. Use switch statement.
* config/rs6000/tm-rs6000.h: Replace SIGTRAP_STOP_AFTER_LOAD with
CHILD_SPECIAL_WAITSTATUS.
struct target_waitstatus. Change status argument to target_wait to
be struct target_waitstatus * instead of int *.
* target.h, infrun.c, all targets: Change type of signal arguments
to resume(), proceed(), and target_resume() from int to enum
target_signal.
* All targets (*_wait, *_resume): Change accordingly.
* infcmd.c (program_info, signal_command), throughout infrun.c,
* fork-child.c, solib.c, hppa-tdep.c, osfsolib.c: Use this stuff.
* convex-xdep.c, convex-tdep.c: Add FIXME's (getting the Convex
signal code stuff right with the new signals would be non-trivial).
* inferior.h (stop_signal): Make it enum target_signal not int.
* target.c, target.h (target_signal_to_string, target_signal_to_name,
target_signal_from_name): New functions.
* inftarg.c, target.h (target_signal_to_host, target_signal_from_host,
store_waitstatus): New functions.
* procfs.c (procfs_notice_signals): Use them.
* i960-tdep.c (i960_fault_to_signal): New function, to replace
print_fault.
* config/i960/tm-i960.h: Don't define PRINT_RANDOM_SIGNAL.
mips_receive_packet.
(callers): pass in mips_receive_wait except mips_initialize (where
we use it to clean up the kludge where we had been changing
mips_receive_wait temporarily) and mips_wait (where we pass in
-1 for no timeout).
* remote-mips.c: Use it instead of error() most places.
* remote-mips.c (mips_receive_packet): New arg throw_error.
(mips_initialize): Use it not catch_errors.
* defs.h: Declare error_pre_print and warning_pre_print here...
* main.c: ...not here.
change caused "p (...)0" to dump core.
* gdbtypes.c (check_stub_method): Don't pass "..." to
parse_and_eval_type. This should fix the bug which Kung was
trying to fix.
two symbols, don't just ignore the second (LOC_REGISTER) one.
* printcmd.c (print_frame_args): If we have a LOC_ARG and a
LOC_REGISTER, use the LOC_ARG not the LOC_REGISTER.
ChangeLog stabsread.c
* stabsread.c (read_type): fix problem when reading static member
of a class. caused by change to allow :: inside template
instantiated name.
from here . . .
* symtab.h: . . . to here.
* dbxread.c (record_minimal_symbol): Move check for gcc{,2}_compiled.
and __gnu_compiled* from here . . .
* minsyms.c (prim_record_minimal_symbol_and_info): . . . to here.
* minsyms.c (prim_record_minimal_symbol): Call
prim_record_minimal_symbol_and_info rather than duplicating code.
stabs-in-elf.
(pastab_build_psymtabs): Likewise.
* hppa-tdep.c: Change all comments to reference %r3 or frame pointer
rather than %r4.
(frame_chain, skip_prologue, dig_rp_from_stack): Handle %r3 as the
frame pointer.
* config/pa/tm-hppa.h (FP_REGNUM): Define as %r3.
(FIND_FRAME_SAVED_REGS): Handle %r3 as frame pointer.
(CALL_DUMMY): Likewise.
* infrun.c (wait_for_inferior): Remove confusing and inaccurate
stuff about subroutine calls, return, etc., from comment which
says "We've wandered out of the step range.".
Sun Dec 26 09:18:10 1993 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
* infrun.c (wait_for_inferior): When checking whether the line has
changed, check the symtab as well.
complain() not warning() if the TYPE_CODE isn't one we know how to
deal with gracefully. Use builtin_type_int not
lookup_fundamental_type (the objfile we passed to
lookup_fundamental_type was sometimes NULL).
The old way (using #undef in tm.h) was ugly and asking for
trouble, because it makes it possible for some file to use the
wrong definition. Move definition of HOST_CHAR_BIT after definition
of TARGET_CHAR_BIT.
* config/alpha/tm-alpha.h, config/h8300/tm-h8300.h,
config/h8500/tm-h8500.h, config/z8k/tm-z8k.h: Don't undef TARGET_*_BIT
before defining them.
* ch-lang.c (chill_is_varying_struct), ch-lang.h: New function.
* ch-lang.c (chill_printstr): Use double quotes, not single quotes.
* ch-typeprint.c (chill_type_print_base): Handle TYPE_CODE_BITSTRING.
Improve printing of TYPE_CODE_STRING, TYPE_CODE_SET, and
TYPE_CODE_STRUCT (including checking chill_is_varying_struct).
Print TYPE_DUMMY_RANGE by printing its TYPE_TARGET_TYPE.
Handle TYPE_CODE_ENUM.
* ch-valprint.c (chill_val_print): Handle TYPE_CODE_BITSTRING.
For TYPE_CODE_STRING, never print address. Handle VARYING strings.
* gdbtypes.c (force_to_range_type): New.
* gdbtypes.c (create_set_type): Make work, following Chill layout.
* gdbtypes.h (TYPE_LOW_BOUND, TYPE_HIGH_BOUND, TYPE_DUMMY_RANGE): New.
* stabsread.c (read_type): Distinguish string and bitstring from
char-array and set.
* valarith.c (value_subscript), valops.c (value_coerce_array):
Handle STRINGs as well as ARRAYs.
* valarith.c (value_bit_index): Fix think. Use new macros.
(DECP_PC_AFTER_BREAK): Now is 0.
* config/h8500/tm-h8500.h (REGISTER_BYTES, REGISTER_BYTE,
REGISTER_NAMES): update to new view. (INIT_EXTRA_FRAME_INFO): No
extra frame info now.
* config/sh/sh.h (NOP): Define NOP insn.
* config/z8k/tm-z8k.h (BIG): is now sim_z8001_mode.
* config/z8k/z8ksim.mt (TDEPFILES): Add remote-sim.o to list.
(go32_readchar): Special handling for faster polling. (async
structure): Volatile.
* h8300-tdep.c (print_register_hook): Allocate and use the right
number bytes for the raw register.
* h8500-tdep.c (regoff, frame_find_saved_reg, examine_prologue):
deleted. (h8500_register_size, h8500_register_virtual_type, ):
Use new way of counting registers.
* remote-e7000.c (echo_index): deleted. (expect): Better handling
of user interrupts. (expect_prompt): Remove never used log file
support. (want, want_nopc): Add support for H8/300H.
(fetch_regs_from_dump): Treat \r and \n as whitespace.
(e7000_drain): Send an "end" command before waiting for output to
stop. (e7000_wait): Cope with H8/300H, better handling of user
interrupts. (why_stop, expect_n, sub2_from_pc): New function.
* remote-utils.c (gr_load_image): call fflush and QUIT more regularly.
* utils.c (notice_quit): New function for polling for user interrupts.
without interpreting that to mean "adjustable."
* ch-valprint.c (chill_val_print): Handle RANGE types.
* ch-typeprint.c (chill_type_print_base): Handle BOOL.
Handle variant records. Handle RANGE types.
* config/mips/idtl.mt: Use tm-idtl.h instead of tm-mips.h.
* config/mipos/tm-idt.h, config/mips/tm-idtl.h: New files; use
different BREAKPOINT value for IDT.
* configure.in (mips-sgi-irix5*): New host and target. Use irix5
for both.
* config/mips/irix5.mh, config/mips/irix5.mt,
config/mips/xm-irix5.h, config/mips/nm-irix5.h,
config/mips/tm-irix5.h, irix5-nat.c: New files for Irix 5 support.
* mdebugread.c: New file, split out of mipsread.c. Added
elfmdebug_build_psymtabs routine. Added some checks on external
symbols. Changed code to keep ecoff_debug_info and
ecoff_debug_swap structs in the psymtab and in global pointers
rather than retrieving them from the bfd. Also changed to keep
the pending list with the psymtab rather than the objfile (each
psymtab for a single objfile points to the same pending list).
* mipsread.c: Bulk of file moved into mdebugread.c, leaving just
the sym_fns.
* Makefile.in (SFILES): Added mdebugread.c.
(OBS): Added mdebugread.o.
(mdebugread.o): New target.
* symfile.h: Declare mdebug_build_psymtabs and
elfmdebug_build_psymtabs.
* elfread.c (struct elfinfo): Added mdebugsect field.
(elf_locate_sections): Remember location of .mdebug section.
(elf_symfile_read): Call elfmdebug_build_psymtabs on .mdebug
section.
* infrun.c (AT_FUNCTION_START): Set to 0 if not already defined.
(wait_for_inferior): Use AT_FUNCTION_START if it is defined to see
if PC is at the start of a function.
* mips-tdep.c (read_next_frame_reg): Use SIGFRAME_REG_SIZE, and
give it a default definition.
(mips_skip_prologue): Skip instructions which initialize $gp
register.
(in_sigtramp): New procedure, moved in from mipsread.c.
* config/mips/tm-mips.h: Declare in_sigtramp.
coredep.o to this list.
* gdb/m88k-nat.c (m88k_register_u_addr): Avoid error when passed
the number for an M88110 extended register by just returning the
address of r0.
ChangeLog symtab.c
* symtab.c(decode_line_1): fix the inconsistency of setting
breakpoint with '' or without them. The '' is needed when you
want name completion.
ChangeLog valops.c
* valops.c(search_struct_method): to use unified search so type
conversion operator works in calling method. (this file should be
checked in with last commit, I missed it).
* valprint.c (val_print_string): When looking for a null
terminator compare current bufsize to fetchlimit to determine
when to stop, instead of computing buffer+fetchlimit which
may overflow for very large limits (like "unlimited").
ChangeLog eval.c valarith.c
* eval.c(evaluate_subexp): to use unified search so type conversion
operator works in calling method.
* valarith.c(value_x_binop, value_x_unop): same as above.
ChangeLog eval.c valops.c
* valops.c (typecmp): improve prototype matching when calling
a method. Make 'p (*(ostream *) &cout) << "lll" ' to work.
* eval.c(evalute_subexp): fix operator search problem when call
like p x.'operator+'(i).
* Makefile.in: (HFILES,TAGFILES): Split into _WITH_SRCDIR and
_NO_SRCDIR versions.
(TAGS): Only add srcdir to TAGFILES_NO_SRCDIR.
(This is part of a long saga involving me putting srcdir on
everything (perhaps for now-obsolete reasons, I forget), Rich
removing the srcdir from everything, Stu putting it back some
places for Sun make, and me just now getting around to fixing
`make TAGS' again).
* gdbtypes.c (check_stub_type): On TYPE_FLAG_TARGET_STUB, do
what cleanup_undefined_types does for arrays, except we clear
TYPE_FLAG_TARGET_STUB if we fix up the type.
* stabsread.c (cleanup_undefined_types): Add comments about how
doing arrays here is no longer the clean way to do it.
(read_array_type): Set TYPE_FLAG_TARGET_STUB as well as calling
add_undefined_type.
* c-typeprint.c, ch-typeprint.c: Move call to check_stub_type
outside switch so it happens for all type codes.
* cp-valprint.c (cp_print_value_fields): Recurse to val_print,
instead of c_val_print, so that check_stub_type gets called.
* gdbtypes.h, gdbtypes.c, m2-lang.c, ch-lang.c, c-lang.c: Remove
TYPE_FLAG_SIGNED. It was inconsistently set, never checked
(except in recursive_dump_type), and is pointless.
