Subject: elf.h (DWARF2_DEBUG_INFO): Define.
X-Git-Tag: releases/gcc-3.1.1~162
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c4ecb1309544d1d30d8171d28d30757b54cfbd7b;p=thirdparty%2Fgcc.git

elf.h (DWARF2_DEBUG_INFO): Define.

        * config/mips/elf.h (DWARF2_DEBUG_INFO): Define.
        * config/mips/mips.c (mips_output_filename): Don't print a
        ".file" directive if we are using DWARF-2.
        (mips_output_function_prologue): Do not emit source file
        name for TARGET_GAS.
