Can you set it to false for MSVC2005?
No, FLAC__AVX_SUPPORTED is 0 (initially it's undefined, then inside cpu.h it's defined as 0). MSVC cannot discard unused references in debug builds and when LTCG is on, for example: <http://lists.ffmpeg.org/pipermail/ffmpeg-devel/2016-April/193437.html> And currently LTCG is enabled for release builds. _______________________________________________ flac-dev mailing list [email protected] http://lists.xiph.org/mailman/listinfo/flac-dev
