From ac8c6e56b9bb1503e26b770080785ba36e3f5dd4 Mon Sep 17 00:00:00 2001 From: Jim Blandy Date: Thu, 23 Jan 2003 23:03:32 +0000 Subject: gdb/ChangeLog: 2003-01-23 Alexander Larsson Jim Blandy 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 * gdb.texinfo (Separate Debug Files): New section. --- gdb/objfiles.h | 11 +++++++++++ 1 file changed, 11 insertions(+) (limited to 'gdb/objfiles.h') diff --git a/gdb/objfiles.h b/gdb/objfiles.h index 39ae44029c8..4dcb6e8c61b 100644 --- a/gdb/objfiles.h +++ b/gdb/objfiles.h @@ -414,6 +414,15 @@ struct objfile ExportEntry *export_list; int export_list_size; + /* Link to objfile that contains the debug symbols for this one. + One is loaded if this file has an debug link to an existing + debug file with the right checksum */ + struct objfile *separate_debug_objfile; + + /* If this is a separate debug object, this is used as a link to the + actual executable objfile. */ + struct objfile *separate_debug_objfile_backlink; + /* Place to stash various statistics about this objfile */ OBJSTATS; }; @@ -505,6 +514,8 @@ extern struct objfile *allocate_objfile (bfd *, int); extern int build_objfile_section_table (struct objfile *); +extern void put_objfile_before (struct objfile *, struct objfile *); + extern void objfile_to_front (struct objfile *); extern void unlink_objfile (struct objfile *); -- cgit v1.2.1
