Subject: libsanitizer/mips: always build with largefile support
X-Git-Tag: upstream/13.1.0~1720
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e08835fd3a4a6559b79c26db9b18df0e838d943e;p=platform%2Fupstream%2Fgcc.git

libsanitizer/mips: always build with largefile support

-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 is always used for mips
when build libsanitizer in LLVM. Thus
   FIRST_32_SECOND_64((_MIPS_SIM == _ABIN32) ? 176 : 160, 216);
instead of
   FIRST_32_SECOND_64((_MIPS_SIM == _ABIN32) ? 160 : 144, 216);
in sanitizer_platform_limits_posix.h.

To keep sync with LLVM and to make the code simple, we use the
largefile options always.

libsanitizer/
	* configure.ac: set -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64
	always for mips*.
	* configure: Regenerate.
