From 3d548a532dd74f9bf5f2033541f0b504d96baf04 Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Mon, 30 Dec 2013 20:34:16 -0700 Subject: move the "main" data into the per-BFD object This adds the "main"-related data into the per-BFD. This is needed because once symbol sharing across objfiles is complete, computing the main name as a side effect of symbol reading will no longer work -- the symbols simply won't be re-read. After this change, set_main_name is only used by the main_name machinery itself, so this patch makes it static. 2014-01-15 Tom Tromey * dbxread.c (process_one_symbol): Use set_objfile_main_name. * dwarf2read.c (read_partial_die): Use set_objfile_main_name. * objfiles.c (get_objfile_bfd_data): Initialize language_of_main. (set_objfile_main_name): New function. * objfiles.h (struct objfile_per_bfd_storage) : New fields. (set_objfile_main_name): Declare. * symtab.c (find_main_name): Loop over objfiles to find the main name and language. (set_main_name): Now static. (get_main_info): Add comment. * symtab.h (set_main_name): Don't declare. --- gdb/objfiles.c | 15 +++++++++++++++ 1 file changed, 15 insertions(+) (limited to 'gdb/objfiles.c') diff --git a/gdb/objfiles.c b/gdb/objfiles.c index c3f6e18..eccb44a 100644 --- a/gdb/objfiles.c +++ b/gdb/objfiles.c @@ -152,6 +152,7 @@ get_objfile_bfd_data (struct objfile *objfile, struct bfd *abfd) obstack_init (&storage->storage_obstack); storage->filename_cache = bcache_xmalloc (NULL, NULL); storage->macro_cache = bcache_xmalloc (NULL, NULL); + storage->language_of_main = language_unknown; } return storage; @@ -186,6 +187,20 @@ set_objfile_per_bfd (struct objfile *objfile) objfile->per_bfd = get_objfile_bfd_data (objfile, objfile->obfd); } +/* Set the objfile's per-BFD notion of the "main" name and + language. */ + +void +set_objfile_main_name (struct objfile *objfile, + const char *name, enum language lang) +{ + if (objfile->per_bfd->name_of_main == NULL + || strcmp (objfile->per_bfd->name_of_main, name) != 0) + objfile->per_bfd->name_of_main + = obstack_copy0 (&objfile->per_bfd->storage_obstack, name, strlen (name)); + objfile->per_bfd->language_of_main = lang; +} + /* Called via bfd_map_over_sections to build up the section table that -- cgit v1.1
