flac dev - Sep 2013 - PATCH: modify/add intrinsics code

The patch does the following:

1. splits lpc_x86intrin.c to lpc_intrin_sse.c and lpc_intrin_sse2.c

2. adds FLAC__lpc_compute_residual_from_qlp_coefficients_intrin_sse2()
    function to lpc_intrin_sse2.c

3. adds lpc_intrin_sse41.c with two ..._wide_intrin_sse41() functions
    (useful for 24-bit en-/decoding)

4. adds precompute_partition_info_sums_intrin_sse2() / ...ssse3() and
    disables precompute_partition_info_sums_32bit_asm_ia32_().
    SSE2 version uses 4 SSE2 instructions instead of 1 SSSE3 instruction PABSD
    so it is slightly slower.


MSVS 2005 doesn't support SSSE3 and SSE4, and GCC compiles
everything with -msse2, so I wrapped SSSE3/SSE4.1 code with
     #ifdef FLAC__SSEx_SUPPORTED ... #endif.
The code that defines FLAC__SSEx_SUPPORTED was added into share/compat.h
(anyone knows a better way to do it?)

(It writes LF in diffs for .c/.cpp/.h/ files and CRLF in diffs for .sln/.vcproj
files,
and then rejects the patch because of CRLF sequences. It accept this patch after
I replaced
all CRLF -> LF).

It looks like that patch was created with the 'git diff' command and
hence
cannot be applied using the 'git am' command. It does however apply
using
the patch command.

Have these patches that I apply look correct when you update your FLAC tree?

I modified the patch that adds ssse3/sse4.1 code:

trailing whitespaces removed;
code cleanup.

New patch attached.

Ooops, patch already applied and pushed when I saw this email.
