gdb/ChangeLog: 2003-01-23 Alexander Larsson <alexl@redhat.com> Jim Blandy <jimb@redhat.com> 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.
