e88bb567f0 Bug 548612. qcms: Reduce size of output lookup tables. r=bgirard
We currently use a larger output lookup table than we probably need. Switch to
a common define for the table size and lower it. The should also give a small
improvement to startup time because we have fewer lookup table entries to
compute.

929a12a259 qcms: Replace second green table release with release of blue table
Cut 'n' paste gone awry: green output table freed instead of blue.

That is, there exists a release for red, 2 releases for green, and none for
blue.

9c3353941f Bug 528322. qcms: Avoid unneeded precision during table creation. r=joe
Switch from pow() to powf() because it's faster and we don't need the
additional precision.  Also avoid unnecessary conversion to and from doubles by
using float constants instead of doubles.

4080919147 Bug 488800. qcms: accept ICCv4 profiles. r=bobbyholley
ICCv4 profiles are a superset of ICCv2 so it shouldn't hurt us to accept them and
just treat them the same way we do ICCv2 profiles.

6a4d539353 Bug 512865. qcms: Improve SSE2 performance, add SSE support. r=jrmuizel
This patch greatly improves the performance of QCMS transformations on x86 &
x86_64 systems.  Some notes:

0. On 32-bit x86 systems it does runtime selection between non-SIMD, SSE, and
SSE2 code paths.

1. On x86_64 systems the SSE2 code path is always taken.  The non-SIMD and SSE
code paths are left intact, but contemporary versions of the GCC and MSVC
compilers will see that they cannot be reached and optimize them away.

2. The execution of the SSE2 code path is reduced by 67%, relative to the
original Intel/Microsoft formatted ASM code.  The relative performance is seen
on a Pentium4 (Northwood) 2.4GHz CPU with DDR1 RAM.

3. The SSE code path provides a 80% reduction in execution time, relative to
the non-SIMD code path.  The relative performance is seen on a Pentium3
(Coppermine) 1.26GHz CPU with SDRAM.

4. The code has been split out into separate files so that it can be built
with different cflags (-msse, and -msse2) when using gcc.

5. Try to land again, this time with __attribute__((__force_align_arg_pointer__))
to avoid crashes on linux.
