* thread-db.c: Various comment fixes and additions.
Include "bfd.h", "symfile.h" and "objfiles.h".
(keep_thread_db): New variable.
(find_new_threads_callback): Remove prototype.
(thread_db_find_new_threads): New prototype.
(thread_db_push_target, thread_db_unpush_target): Remove
functions.
(deactivate_target): New function.
(thread_db_new_objfile): If OBJFILE == NULL, force deactivation of
target vector. Activate target vector directly instead of calling
thread_db_push_target. Set keep_thread_db if thread library is
detected in the main symbol file. Only enable thread event
reporting if there actually is a child process. Likewise for
detecting new threads, done by calling thread_db_find_new_threads
instead of iterating over the threads ourselves.
(thread_db_detach): Call deactivate_target instead of
thread_db_unpush_target.
(thread_db_wait): Bail out early if we're not debugging the
multi-threaded child process yet.
(thread_db_post_startup_inferior): New function.
(thread_db_mourn_inferior): Call deactivate_target instead of
thread_db_unpush_target.
(init_thread_db_ops): Add thread_db_post_startup_inferior to
thread_db_ops.
(i386_extract_return_value): Return directly after issuing the
warning and filling *VALBUF with zeroes if we cannot get at the
floating-point registers.
(i386_store_return_value): New function.
* config/i386/tm-i386.h (STORE_RETURN_VALUE): Simply call
i386_store_return_value.
Add prototype for i386_store_return_value.
* Makefile.in (UIOUT_CFLAGS): New macro. CFLAGS needed for uiout code
to be compiled. Defines UI_OUT.
(SUBDIR_MI_CFLAGS): Defines MI_OUT, not UI_OUT.
(INTERNAL_WARN_CFLAGS): Also include UIOUT_CFLAGS.
* configure.in (UIOUT_CFLAGS): New configuration variable.
(--with-uiout): New configuration option. Causes uiout code to
be compiled, instead of the old *printf one.
* configure: Regenerate.
* top.c (print_gdb_version): Test for and print MI_OUT, not UI_OUT.
* testsuite/lib/mi-support.exp (mi_gdb_start): Test for MI_OUT,
not UI_OUT.
* complaints.c (complain): Call warning_hook if defined, instead of
writting to gdb_stderr.
(clear_complaints): Do not write anything to gdb_stderr if warning_hook
is defined.
* sh-tdep.c (sh_generic_show_regs, sh3_show_regs, sh3e_show_regs,
sh3_dsp_show_regs, sh4_show_regs, sh_dsp_show_regs): SR_REGNUM is
now part of gdbarch_tdep structure.
(sh_gdbarch_init): Initialize SR_REGNUM.
* config/sh/tm-sh.h (struct gdbarch_tdep): Add field SR_REGNUM.
* sh-tdep.c (sh_do_pseudo_register): Indent properly. Call
do_dr_register_info() only for DR registers.
(sh_sh4_register_name): Add comments with numbers.
(_initialize_sh_tdep): Move assignment to disassemble printing
function from here...
(sh_gdbarch_init):...to here. Move some more general settings to
before the architecture is recognized.
* Makefile.in (CONFIG_LOBS): New macro. Configured to the files
that must be added to the gdblib itself.
(DEPFILES): Use CONFIG_LOBS, not CONFIG_OBS.
(INIT_FILES): Include CONFIG_OBS.
(gdb$(EXEEXT)): Depend on CONFIG_OBS and link with it.
(kdb): Ditto.
* configure.in (CONFIG_LOBS): New variable. Object files that must
be added to gdblib for the specific configuration.
* configure: Regenerate.
* Makefile.in (SUBDIR_GDBTK_OBS, SUBDIR_GDBTK_SRCS,
SUBDIR_GDBTK_DEPS, SUBDIR_GDBTK_INITS, SUBDIR_GDBTK_LDFLAGS,
SUBDIR_GDBTK_CFLAGS): New macros. For gdbtk subdir.
* configure.in: Fix typo. It is CONFIG_OBS not CONFIG_OJS.
Use the SUBDIR_GDBTK_* macros instead of hard coded file names.
* configure: Regenerate.
* configure.in: Fix a couple of typos in the handling of the
enable_gdbcli option. Make it check enableval for the result
of AC_ARG_ENABLE.
* configure: Regenerate.
* gdb.base/break.exp (test_clear_command): Use a marker function
rather than 'main' for the test function. Also move this
test to an execution point where the marker function names are
guaranteed to be bound to functions. (Executing tests after a
'finish' from main runs into name conflicts with local names
in __libc_start_main).
* dwarf2read.c (DWARF2_REG_TO_REGNUM): New macro. Provide default
definition. Will be used to translate between the compiler's
register numbering and GDB's (for register variables etc).
(new_symbol): Use DWARF2_REG_TO_REGNUM to translate register ids.
* gdb.base/finish.exp: New test for gdb's "finish" command.
* gdb.base/return2.exp: New test for gdb's "return" command.
* gdb.base/return2.c: New source file for above.
* config/sh/tm-sh.h (struct gdbarch_tdep): Rename fields
{FP15,DR14,FV12}_REGNUM to {FP,DR,FV}_LAST_REGNUM.
* sh-tdep.c (sh_sh3e_register_virtual_type,
sh_sh4_register_virtual_type, sh_do_registers_info,
sh_gdbarch_init, sh_sh4_register_byte, sh_sh4_register_raw_size,
sh_sh4_register_convertible, sh_sh4_register_convert_to_virtual,
sh_sh4_register_convert_to_raw, sh_fetch_pseudo_register,
sh_store_pseudo_register, sh_do_pseudo_register): Ditto.
* sh-tdep.c (sh_gdbarch_init): Use a function pointer to set the
disassembly print function.
(_initialize_sh_tdep): Initialize tm_print_insn using the function
pointer.
