From 61214be10b12d26d2ec7855d9a8681a155b0f953 Mon Sep 17 00:00:00 2001 From: Trevor Saunders Date: Mon, 14 Nov 2016 10:58:48 +0000 Subject: [PATCH] remove conditional compilation of HAVE_AS_LEB128 code gcc/ChangeLog: 2016-08-20 Trevor Saunders * acinclude.m4 (gcc_GAS_CHECK_FEATURE): Support doing an action if the feature isn't available. * configure: Regenerate. * configure.ac: define HAVE_AS_LEB128 to 0 when not available. * dwarf2asm.c (dw2_asm_output_data_uleb128): Always compile code for HAVE_AS_LEB128. (dw2_asm_output_data_sleb128): Likewise. (dw2_asm_output_delta_uleb128): Likewise. (dw2_asm_output_delta_sleb128): Likewise. * except.c (output_one_function_exception_table): Likewise. (dw2_size_of_call_site_table): Likewise. (sjlj_size_of_call_site_table): Likewise. * dwarf2out.c (output_loc_list): Likewise. (output_rnglists): Likewise.
