OK, the attached patch adds FLAC__SSE*_SUPPORTED and also moves their
definitions to cpu.h.
It also adds GCC 4.9 support (http://gcc.gnu.org/gcc-4.9/changes.html:

PATCH: add FLAC__SSE_SUPPORTED and FLAC__SSE2_SUPPORTED
Currently the only way to compile FLAC using GCC w/o SSE support
is to disable asm optimizations (see configure.ac):
if test "x$asm_optimisation" = "xyes" ; then
XIPH_ADD_CFLAGS([-msse2])
fi
Also it's not possible to enable SSE4.1 intrinsic functions even
with -msse4.1 option. The patch fixes both problems.

PATCH for stream_encoder.c: change ifdefs order
Erik de Castro Lopo wrote:

Thanks. And btw, about reformatting: currently stream_encoder.c contains the following code:
#ifdef FLAC__SSSE3_SUPPORTED
if(encoder->private_->cpuinfo.ia32.ssse3)
aaaaa;
else
#endif
#ifdef FLAC__SSE2_SUPPORTED
bbbbb;
#endif
This code is correct because if FLAC__SSSE3_SUPPORTED is defined then
FLAC__SSE2_SUPPORTED is also defined (there are no compilers that support ssse3 but
don't support sse2), so there is no missing statement after 'else'. But imho
the following version is more easy to r...
