From: Tom Tromey Date: Mon, 21 May 2018 05:28:39 +0000 (-0600) Subject: Move the using directives to buildsym_compunit X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6cccc9a89160455aab634784c231af4590d943f3;p=binutils-gdb.git Move the using directives to buildsym_compunit This moves the globals local_using_directives and global_using_directives to be members of buildsym_compunit, and adds the necessary accessors. gdb/ChangeLog 2018-07-16 Tom Tromey * dwarf2read.c (using_directives, read_func_scope) (read_lexical_block_scope): Update. * cp-namespace.c (cp_scan_for_anonymous_namespaces): Update. * buildsym.h (local_using_directives, global_using_directives): Don't declare. (get_local_using_directives, set_local_using_directives) (get_global_using_directives): Declare. * buildsym.c (struct buildsym_compunit) : New members. (finish_block_internal, prepare_for_building) (reset_symtab_globals, end_symtab_get_static_block) (push_context): Update. (get_local_using_directives, set_local_using_directives) (get_global_using_directives): New functions.
