Add support for executables whose debug info has been separated
out into a separate file, leaving only a link behind.
* objfiles.h (struct objfile): New fields: separate_debug_objfile
and separate_debug_objfile_backlink.
(put_objfile_before): New declaration.
* symfile.c: #include "filenames.h".
(symbol_file_add_with_addrs_or_offsets): If this objfile has its
debug info in a separate file, read that, too. Save the addrs
argument, so we can use it again to read the separated debug info;
syms_from_objfile modifies the table we pass it.
(reread_symbols): After re-reading an objfile, call
reread_separate_symbols to refresh its separate debug info
objfile, if it has one.
(reread_separate_symbols, find_separate_debug_file,
get_debug_link_info, separate_debug_file_exists): New functions.
(debug_file_directory): New global var.
(_initialize_symfile): Initialize debug_file_directory, and
provide the new `set debug-file-directory' command to let the user
change it.
* objfiles.c (free_objfile): If this objfile has its debug info in
a separate objfile, free that one too. If this is itself a
separate debug info objfile, clear our parent's backlink.
(put_objfile_before): New function.
* utils.c (gnu_debuglink_crc32): New function.
* defs.h (gnu_debuglink_crc32): New declaration.
* Makefile.in (symfile.o): Note dependency on "filenames.h".
* configure.in: Handle --with-separate-debug-dir config option.
* acinclude.m4 (AC_DEFINE_DIR): New macro.
* acconfig.h (DEBUGDIR): New macro.
* configure, aclocal.m4, config.in: Regenerated.
gdb/doc/ChangeLog:
2003-01-23 Jim Blandy <jimb@redhat.com>
* gdb.texinfo (Separate Debug Files): New section.
AC_CHECK_FUNCS and remove the old check for pread64.
* acinclude.m4 (AC_GNU_SOURCE): New macro.
* acconfig.h (_GNU_SOURCE): Add.
(HAVE_PREAD64): Remove.
* configure, aclocal.m4, config.in: Regenerated.
gratuitious whitespace changes.
[!HAVE_SIGPROCMASK]: Call sigsetmask if HAVE_SIGSETMASK is defined.
* top.c: Remove redundant logic to define HAVE_SIGSETMASK.
(sigsetmask) Don't define macro.
(stop_sig) [HAVE_SIGPROCMASK]: Add bit of code snatched from
async_stop_sig from event-top.c.
[!HAVE_SIGPROCMASK]: Call sigsetmask if HAVE_SIGSETMASK is
defined.
* configure.in (AC_CHECK_FUNCS): Put functions in alphabetical
order. Add sigsetmask.
(AC_FUNC_VFORK, AC_FUNC_ALLOCA): Reorder such that they're in
alphabetical order.
* config/xm-aix4.h, config/alpha/xm-alphalinux.h,
config/i386/xm-cygwin.h, config/rs6000/xm-rs6000.h
(HAVE_SIGSETMASK): Remove.
* aclocal.m4, config.in, configure
(AC_FUNC_SETPGRP): Add.
* aclocal.m4, configure, config.in: Regenerated.
* inflow.c (gdb_setpgid): Get rid of NEED_POSIX_SETPGID and
SETPGRP_ARGS. Always use setpgid if it is available, fall back on
setpgrp if it isn't. Use SETPGRP_VOID (defined by autoconf) to
distinguish between the two setpgrp flavours.
* config/xm-sysv4.h, config/arm/xm-linux.h,
config/i386/xm-i386aix.h, config/i386/xm-sco.h,
config/i386/xm-linux.h, config/i386/xm-ptx.h,
config/m68k/xm-linux.h, config/powerpc/xm-linux.h,
config/sparc/xm-linux.h, config/sparc/xm-sun4sol2.h,
config/ia64/xm-linux.h (NEED_POSIX_SETPGID): Remove.
* config/rs6000/xm-rs6000.h (SETPGRP_ARGS): Remove.
* Makefile.in: Add GDBTK_CFLAGS - this is now used to hold
-fwritable-strings when compiling with Tk8.1.
* configure.in: Add GDBTK_CFLAGS, set it to -fwritable-strings for
Tcl/Tk8.1 & greater.
* acinclude.m4: Move the rest of the defines to find Itcl, Itk &
Tix from aclocal.m4 to here.
* aclocal.m4: regenerate.
* configure: regenerate.
* gdbtk-hooks.c (x_event): Tcl_ObjGetVar2 was removed from
Tcl8.1. Use Tcl_GetVar2 instead.
* gdbtk-hooks.c (gdbtk_trace_find): Fix up call to
Tcl_GlobalEvalObj for Tcl/Tk 8.1.
* gdbtk-hooks.c (gdbtk_trace_start_stop): Call to Tcl_EvalObj was
inefficient, replace with call to Tcl_GlobalEval.
* gdbtk.c: Don't swap out the Tcl_Alloc calls in gdbtk.c. We took
care of that in Tcl itself for 8.1.
* gdbtk.c: Remove const from the script string since Tcl8.1 has
taken to scribbling sentinals into strings passed to it again...
* gdbtk-cmds.c (wrapped_call): Change declaration of 1st arg from
char * to PTR to eliminate warning.
* gdbtk-cmds.c (perror_with_name_wrapper): Ditto
* acinclude.m4: New file, containing the hand-written local macro
definitions that used to be in aclocal.m4. Don't sinclude
../bfd/aclocal.m4 any more; running aclocal in this directory will
get us the definitions we need. HOWEVER: Do sinclude
../bfd/acinclude.m4, because we need the definition of
BFD_NEED_DECLARATION.
* aclocal.m4: Regenerated by aclocal.
* configure: Regenerated by autoconf.
* configure.in: Add --enable-warnings.
Adjust whitespace of other --with and --enable options so that
configure --help lines up correctly.
* aclocal.m4: Ditto.
* Makefile.in (WARN_CFLAGS): Add. Set by configure.
* configure: Regenerated.
* aclocal.m4: add EXEEXT setting rule
* configure.in: call it
* configure: regenerate
* Makefile.in: pepper with EXEEXTs in appropriate places,
set SHELL = @SHELL@ for those lame hosts that don't have a /bin/sh
_WIN32.
(Tcl_Realloc, Tcl_Free): Likewise.
* configure.in: Check for cygwin32 environment. Define and
substitute WIN32LIBS and WIN32LDAPP. Always set configdir to
unix; setting it to win was for an old Tcl/Tk configuration
scheme.
* aclocal.m4 (CY_AC_LOAD_TKCONFIG): Substitute TK_BUILD_INCLUDES.
* Makefile.in (TK_CFLAGS): Add @TK_BUILD_INCLUDES@.
(WIN32LDAPP, WIN32LIBS): Define.
(CLIBS): Add $(WIN32LIBS).
(gdb): Use $(WIN32LDAPP).
* configure: Rebuild.
* Makefile.in, configure.in, aclocal.m4: Add Itcl, Tix, and
IDE configuration information.
* gdbtk.c (breakpoint_notify): Send address, linenumber and
filename when a breakpoint is set. Avoids call to bp_info.
(gdbtk_init): Call Tcl_FindExecutable(). Add code to handle
Itcl, Tix and IDE initialization.
* defs.h (init_ui_hook): Change prototype to accept one arg.
* main.c (gdb_init): Change prototype to accept one arg.
* top.c (gdb_init): Accepts one argument which it uses to
call (*init_ui_hook), which will be gdbtk_init(). This is
used for calling Tcl_FindExecutable().
* gdbtcl/breakpoint.tcl (gdbtk_tcl_breakpoint): Change to
accept variable number of args for compatibility with
cchanges in gdbtk.c.
* configure: Regenerated.
* gdbtcl/tclIndex: Regenerated.
* Makefile.in: Install gdbtcl dir instead of gdbtk.tcl.
* gdbtk.c: Added some ifdefs for Windows. Changed GDBTK_FILENAME
to GDBTK_LIBRARY, which is now a path to search.
(gdb_path_conv): New function. Convert Cygwin32 pathname to
DOS-style pathname.
* aclocal.m4, configure.in: Changes for Windows builds.
* configure: Rebuilt.
* configure.in: Add stdlib.h to AC_CHECK_HEADERS. Call
BFD_NEED_DECLARATION on malloc, realloc, and free.
* acconfig.h: Add NEED_DECLARATION_MALLOC,
NEED_DECLARATION_REALLOC, and NEED_DECLARATION_FREE.
* configure, config.in: Rebuild.
* defs.h: Include <stddef.h> and <stdlib.h> based on HAVE_*_H
rather than __STDC__. Only declare malloc, realloc, and free if
NEED_DECLARATION_* is defined.
* gdbtk.c (mainWindow): Deleted.
(cleanup_init): Don't destroy main window.
(gdbtk_init): Main window now created by Tk_Init.
* configure.in: Most X checks now handled automatically by Tk.
Use new macros to find Tcl/Tk.
* aclocal.m4: New version for new Tcl/Tk; from Don Libes.
* config.in, configure: Regenerated.
* Makefile.in (TCL, TCL_CFLAGS, TK, TK_CFLAGS, X11_CFLAGS,
X11_LDFLAGS, X11_LIBS): Changed for new Tcl and Tk.
config/m68k/m68kv4.mh, config/mips/{irix4.mh, irix5.mh,
mipsv4.mh}, config/sparc/sun4so2.mh (INSTALL): Removed, figured
out by autoconf.
* config/apollo68v.mh (RANLIB): Removed, figured out by autoconf.
* Makefile.in, configure.in: Converted to use autoconf
* aclocal.m4: New file, local autoconf macro definitions.
* configure: New file, generated with autoconf 2.3.
