43da8f147c Change non-function symbol vp8_ prefixes to vp9_. 
For local symbols, make them static instead.

c5f890af2c Use local labels for jumps/loops in x86 assembly. 
Prepend . to local labels in assembly code.  This
allows non unique labels within a file.  Also
makes profiling information more informative
by keeping the function name with the loop name.

4a2b684ef4 modify SAVE_XMM for potential 64bit use 
the win64 abi requires saving and restoring xmm6:xmm15. currently
SAVE_XMM and RESTORE XMM only allow for saving xmm6:xmm7. allow
specifying the highest register used and if the stack is unaligned.

70f30aa95d store quant_shift as an unsigned char 
in encodframe.c, quant_shift is set to 0 or 1 in vp8cx_invert_quant

only use 8 bits to store this, instead of 16. will allow saving an
xmm register in an updated version of the regular quantize

c32e0ecc59 use asm_offsets with vp8_fast_quantize_b_sse2 
on the same order as the regular quantize change: ~2%

8520b5c785 tweak vp8_regular_quantize_b_sse2 
rather than look up rc in the zig zag table, embed it in the macro. this
also allows us to shuffle some values in the macro and keep *d in rsi

gains of about the same order as the obj_int_extract implementation: ~2%

8edaf6e2f2 use asm_offsets with vp8_regular_quantize_b_sse2 
remove helper function and avoid shadowing all the arguments to the
stack on 64bit systems

when running with --good --cpu-used=0:
~2% on linux x86 and x86_64
~2% on win32 x86 msys and visual studio
more on darwin10 x86_64
significantly more on
x86_64-win64-vs9

15f9bea73b update sse2 regular quantizer 
about ~5% gain on 32bit. disabled for 64bit

unset executable bit on ssse3 version (cosmetic)

e0cf330cde vp8 fast quantizer sse2 optimizations for eob. 
Changed the end of block computation to use pmaxw.  Removed
additional pushing and popping of registers that was not needed.

1dc0ca1340 Fix compiler warning about vp8_fast_quantize_b_impl_ssse2. 
Typo had function defined as _ssse2 and prototyped as _sse2.

d860f685b8 Added vp8_fast_quantize_b_sse2 
Moved vp8_fast_quantize_b_sse from quantize_mmx.asm into
quantize_sse2.asm and renamed.  Updated the assembly code to
match the C version.

c2140b8af1 Use WebM in copyright notice for consistency 
Changes 'The VP8 project' to 'The WebM project', for consistency
with other webmproject.org repositories.

Fixes issue #97.

c8134bc54a nasm: use OWORD vs DQWORD 
nasm knows only OWORD.  yasm knows both OWORD and DQWORD.

Provide nasm compatibility.  No binary change by this patch with yasm on
{x86_64,i686}-fedora13-linux-gnu.  Few longer opcodes with nasm on
{x86_64,i686}-fedora13-linux-gnu have been checked as safe.

48c84d138f sse2 version of vp8_regular_quantize_b 
Added sse2 version of vp8_regular_quantize_b which improved encode
performance(for the clip used) by ~10% for 32 bit builds and ~3% for
64 bit builds.

Also updated SHADOW_ARGS_TO_STACK to allow for more than 9 arguments.
