From a1b34d156a85f8c93af66a3677e75a132bfcc54a Mon Sep 17 00:00:00 2001 From: Yao Qi Date: Tue, 26 Aug 2014 21:02:49 +0800 Subject: [PATCH] Remove dwarf_decode_lines argumewant_line_info Hi, dwarf_decode_lines is called in two functions, dwarf2_build_include_psymtabs and handle_DW_AT_stmt_list, in which, 1 is passed to argument 'want_line_info' and 'want_line_info' is a conditional variable in dwarf_decode_lines. We can simplify it by removing 'want_line_info' and propagating the constant 1 into dwarf_decode_lines. This is what this patch does. This patch also remove one line comment about WANT_LINE_INFO in handle_DW_AT_stmt_list, as handle_DW_AT_stmt_list doesn't have such argument. gdb: 2014-08-28 Yao Qi * dwarf2read.c (dwarf_decode_lines): Update declaration. (handle_DW_AT_stmt_list): Remove comment about WANT_LINE_INFO. (dwarf_decode_lines): Remove argument want_line_info. Remove condition check on want_line_info.
