* coffread.c (coff_symtab_read): In the case of C_THUMBEXT |
C_THUMBEXTFUNC | C_EXT, sec will never ever be the index for
.rodata, because cs_to_section doesn't deal with .rodata. Fix test
accordingly.
* solib.c (symbol_add_stub): Remember the index and the name of
the section with the lowest address. Use this data (instead of
data from .text) to pass info into symbol_file_add.
* elfread.c (record_minimal_symbol_and_info): Use the section
where the symbol lives to get the index, instead of guessing.
Make Sparc a Multi-Arch target. Discard PARAMS macro (require ANSI).
* sparc-tdep.c: include arch-utils.h.
(SPARC_HAS_FPU, FP_REGISTER_BYTES, FP_MAX_REG NUM, SPARC_INTREG_SIZE,
DUMMY_REG_SAVE_OFFSET): provide multi-arch-compatible definitions.
(GDB_TARGET_IS_SPARC64): make into a runtime test.
(struct frame_extra_info): Define, use instead of the macro.
(Many places): Use alloca instead of statically allocated buffers
that depend on a multi-arch variable such as MAX_REGISTER_RAW_SIZE.
(sparc_extract_struct_value_address): Accept a pointer arg instead
of an array sized by REGISTER_BYTES.
(examine_prologue): Accept a pointer to an array of CORE_ADDR,
instead of the defunct struct frame_saved_regs. Recognize new
Sparc64 store instructions as part of the prologue. Ignore the
destination of a frame store when parsing the prologue (so long
as it's on the stack).
(sparc_push_dummy_frame): Fix incorrect buffer offset for PSTATE.
(sparc_frame_find_saved_regs): Accept a ptr to an array of CORE_ADDR
instead of the defunct struct frame_saved_regs.
(supply_gregset): Discard unnecessary 'zerobuf': just send NULL to
supply_register. Provide 4-byte offset to compensate for diff
between size of the prgreg_t elements on a 64-bit host and size
of the registers for a 32-bit target. Fill all inaccessible regs
with zero so they won't keep being requested again and again.
(fill_gregset): Handle 32/64 size difference between registers
and prgreg_t. Handle as many new 64-bit regs as possible.
(supply_fpregset, fill_fpregset): Attempt to handle 64-bit world.
(sparc_push_arguments): Rename to sparc32_push_arguments.
Copy arguments into registers as well as onto stack, so that the
CALL_DUMMY (code pushed onto the target stack) is not required.
(sparc_extract_return_value): Rename to sparc32_extract_return_value.
(sparc_store_return_value): Use memset instead of bzero.
Use write_register_gen instead of write_register_bytes.
(sparclet_store_return_value): New function.
(_initialize_sparc_tdep): Call register_gdbarch_init to activate
the gdbarch multi-architecture system.
(sp64_push_arguments): Rename to sparc64_push_arguments.
Extend to store arguments in general registers as well as on stack.
(sparc64_extract_return_value): Rename to sp64_extract_return_value.
Use as a private function, to be called by the new external function
sparc64_extract_return_value.
(sparclet_extract_return_value): New function.
(sparc32_stack_align, sparc64_stack_align, sparc32_register_name,
sparc64_register_name, sparc_print_extra_frame_info,
sparclite_register_name, sparclet_register_name,

sparc_coerce_float_to_double, sparc_call_dummy_address,
sparc_y_regnum, sparc_reg_struct_has_addr, sparc_intreg_size,
sparc_return_value_on_stack): New functions supporting multi-arch.
(sparc_gdbarch_init): New function; initialize multi-arch.
(struct gdbarch_tdep): Define, use for private multi-arch data.
* config/sparc/tm-sparc.h: Move definitions around, enclose with
#ifdef GDB_MULTI_ARCH tests, provide some multi-arch alternate
definitions. Add enums for register names, to help debugging gdb.
This header file must work for non-multi-arch and for multi-arch.
* config/sparc/tm-sp64.h: Add GDB_MULTI_ARCH configuration. Also add
AT_ENTRY_POINT definitions for CALL_DUMMY, for non-multi-arch case.
Define GDB_MULTI_ARCH.
* config/sparc/tm-sparclet.h: Add GDB_MULTI_ARCH configuration.
Do not define GDB_MULTI_ARCH (bfd does not correctly identify target).
* config/sparc/tm-sparclite.h: Ditto.
* config/sparc/tm-sun4sol2.h: Define GDB_MULTI_ARCH.
* sparclet-rom.c (sparclet_regnames): Initialize explicitly, to
avoid using deprecated REGISTER_NAMES macro.
* Makefile.in: Let sparc-tdep.c depend on arch-utils.h.
* gdbarch.sh: Add FP0_REGNUM to list of multi-arched register numbers.
* gdbarch.c, gdbarch.h: Regenerate.
* core-regset.c: Change FP0_REGNUM to a runtime test.
* procfs.c: Ditto.
* sun3-nat.c: Ditto.
* sparc-tdep.c: Ditto.
* i386mach-nat.c: Remove unnecessary ifdef for FP0_REGNUM.
* ptx4-nat.c: Ditto.
* sol-thread.c (sol_thread_create_inferior): only add the thread
to the thread list if it is not already in there.
(prototypes for thread_db func ptrs): pretty up formatting.
* sol-thread.c (sol_thread_create_inferior): only add the thread
to the thread list if it is not already in there.
(prototypes for thread_db func ptrs): pretty up formatting.
with the version name.
* config/djgpp/djconfig.sh: Use more warning switches.
* config/djgpp/fnchange.lst: Replace the leading gdb-0222 with the
@V@ placebo.
* procfs.c: Cleanup of procfs tracing. Move defines and
prototypes to proc-utils.h
* proc-utils.h: Define tracing macros. Declare trace functions.
* proc-api.c: Make procfs tracing a runtime option.
(prepare_to_trace): New function, abstracted out of several
places. Open a trace file if one is required.
(ioctl_with_trace, write_with_trace, open_with_trace,
close_with_trace, wait_with_trace, lseek_with_trace):
Report errno if an error occurs in a system call.
(write_with_trace): Make 2nd arg void *, to agree with write.
* elfread.c (elf_symtab_read): The calculation of 'offset'
must be done for each symbol, not just once. The index
used must be the index of the section where 'sym' resides,
not .text.
* procfs.c (many functions): change int cmd; to long cmd;
Solaris /proc API calls this parameter a long, and requires it
for 64-bit hosts (where sizeof(long) != sizeof(int)). UnixWare
calls it an int, but on existing UnixWare hosts, int and long
are the same size. So long it must be. If a future UnixWare
version has problems with this, we'll have to use autoconf.
* proc-api.c (write_with_trace): use long instead of int.
* solib.c (elf_locate_base, info_sharedlibrary_command):
Look at the bfd to determine if it is elf32 or elf64, rather
than using an ifdef. This makes it runtime teststable and
multi-arch.
stepping out of a signal handler into its calling trampoline
ignore the value of step_frame_address.
(step_over_function): Only modify step_resume_breakpoint->frame if
the value of step_frame_address is non-zero.
TeX.
* gdb.texinfo: Add "@syncodeindex fn cp". Convert all entries
"@kindex f" into "@kindex f (foo)", otherwise we get index entries
like `n' and `s' which look weird. Convert some of the @kindex to
@vindex, when they refer to variables, not commands.
* procfs.c (comments): Eliminate "???" in comments, which GCC
wants to interpret as a trigraph. (fill_gregset, supply_gregset,
fill_fpregset, supply_fpregset): declare.
(procfs_wait): Sysargs is a long, change printf format to match.
(test-mapping, mapping_test, test_mapping_cmd) Remove (test only).
* gdb.base/call-ar-st.exp: Bail out if target is sparclet.
This test depends on parsing the printf output from the target.
Since the sparclet stub doesn't do stdio, this will never work.
* gdb.base/call-rt-st.exp: ditto.
* gdb.base/call-strs: ditto.
* gdb.base/miscexprs.exp: make sizeof long array test portable.
* gdb.base/ending-run.exp: After connecting to a remote target,
but before running, the target will appear to be in a random
location. Specify both a file and a line for breakpoints.
Also, the function that calls main may be called 'init'
rather than 'start'.
(SET_TEXINPUTS): Add $(GDBMI_DIR).
(SFILES_DOC): Add $(GDBMI_DIR)/gdbmi.texinfo.
(gdbmi.texinfo): New target, for texi2roff.
(gdb.me, gdb.ms, gdb.mm): Depend on gdbmi.texinfo.
(gdb.info, gdb_toc.html): Add "-I ${GDBMI_DIR}".
* gdb.texinfo (Top): Add GDB/MI to the main menu and @include
gdbmi.texinfo.
(Mode Options): Add xref to GDB/MI docs and remove a FIXME
comment.
* gdbmi.texinfo: Lots of changes, to include this document as part
of the GDB manual.
* TODO, NEWS: Update due to inclusion of gdbmi.texinfo in the GDB
manual.
run-time test for STACK_ALIGN_P.
* gdbarch.sh: Add support for function and variable predicates.
(STACK_ALIGN): Add. Implement with predicate - STACK_ALIGN_P.
* gdbarch.h, gdbarch.c: Re-generate.
void*.
From Philippe De Muyter <phdm@macqel.be>:
* printcmd.c (print_address_symbolic): Call `make_cleanup' with
`(free_current_contents, &x)', not `(free, x)'.
* utils.c (free_current_contents): Do not `free (NULL)'.
* printcmd.c (print_address_symbolic): Cleanup after a failed
call to build_address_symbolic.
(mempool): Just free any buffer prior to reuse. Don't bother with realloc.
(flag_single_step): New function.
(skip_message): Detect "helpful" Windows CE messages and skip sending them to
the host.
(wait_for_debug_event): Use skip_message to avoid sending debug messages to the
host.
(dispatch): Prelimary implementation of single step detection.
* wince.c: Rework SH single stepping code to be more consistent with other
wince targets.
(handle_output_debug_string): Allow first chance exceptions to come through
since they seem to be all that we get on some versions of Windows CE.
(check_for_step): New function, conditionally compiled based on target.
(regptr): Delete obsolete function.
(handle_exception): Detect illegal instructions.
(get_child_debug_event): Return success only if event code matches target.
(child_create_inferior): Reflect change to get_child_debug_event arguments.
suspended threads.
(safe_symbol_file_add_stub): New function.
(safe_symbole_file_add_cleanup): New function.
(safe_symbol_file_add): New function.
(handle_load_dll): Use wrapper to add DLL symbol information to avoid bogus
errors from non-stabs DLLs.
(handle_exception): Add work around for detection of first exception breakpoint
which does not seem to occur on W2K. Detect more "signals" that can be
effectively passed to the debuggee. Reorganize to eliminate continue_status
global.
(child_continue): Reorganize to eliminate continue_status global.
(child_wait): Ditto.
(child_resume): Ditto.
(get_child_debug_event): Ditto. Recognize when an a breakpoint exception
should be ignored. Change method for signalling when an important event has
occured to the caller.
(child_create_inferior): Use new method for noticing when get_child_debug_event
has found something interesting.

Since nobody had made any changes to i386v-nat.c on sourceware since
the repository was started, we were still getting the version from the
vendor branch. (If you don't understand how the vendor branch works,
treasure your innocence.) I naively assumed that, to see what changes
had been introduced in version 1.2, one should diff it with 1.1,
as they say in TV Guide, "with hilarious results".
This change simply restores i386v-nat.c to what it used to be before I
started bungling around. The text of this revision should be
identical to that of revision 1.1.1.3, which was the former head of
the trunk. (Yes, 1.1.1.3 was the head of the trunk. As I said,
treasure your innocence.)
* symfile.h (struct section_addr_info ): Remove fields for special
treatment of .text, .data and .bss sections.
