From b6bf44ba1b497f5cf654851f6c360313b05345f4 Mon Sep 17 00:00:00 2001 From: Alan Modra Date: Fri, 3 Aug 2001 01:11:21 +0000 Subject: * ld.texinfo (Input Section Basics): Clarify ordering of output sections. * ldlang.c (callback_t): Add wildcard_list param. (walk_wild_section): Remove "section" param. Rewrite for lang_wild_statement_type change. Remove unique_section_p test. (walk_wild_file): Remove "section" param. (walk_wild): Remove "section" and "file" params. (lang_gc_wild): Likewise. (wild): Likewise. Modify for lang_wild_statement_type change. (wild_sort): Likewise. Add "sec" param. (gc_section_callback): Likewise. (output_section_callback): Likewise. Do unique_section_p test. (map_input_to_output_sections): Modify call to wild. (lang_gc_sections_1): Likewise. (print_wild_statement): Modify for lang_wild_statement_type change. (lang_add_wild): Replace filename, filenames_sorted param with filespec. Replace section_name, sections_sorted, exclude_filename_list with section_list. * ldlang.h (lang_add_wild): Here too. (lang_wild_statement_type): Replace section_name, sections_sorted, and exclude_filename_list with section_list. * ldgram.y (current_file): Delete. (%union): Add wildcard_list.
