2f0c136e1f Check whether IBM or Apple PPC assembler syntax is used 
This checks which assembler syntax is supported and defines macros
for register names accordingly.

59bebb11e0 mpegaudio: move compute_antialias_float() to mpegaudiodec_float.c 
Also put compute_antialias_integer() under !CONFIG_FLOAT and change
forward declarations to declare only the relevant one of these.

Fixes warnings about unused functions and pointer type mismatches.

35d597d556 mpegaudio: call ff_mpegaudiodec_init_mmx() only from float decoder 
The mmx code is floating-point only, and this function does not know
from which decoder it is called.  Without this change, the integer
decoder only "works" because the size of the context struct is smaller
in this case, and the mmx init function writes the function pointer
outside the allocated context.

Fixes issue 2054.

4148855ee4 Eliminate another redundant instruction in vp56/8 arithcoder 
Necessary because of this GCC bug:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44474
To do this, convert some, but not all (!) of the variables in VP56RangeCoder
into local variables.
If we convert c->high into a local variable, gcc gets the stupids and refuses
to use a conditional move for the unpredictable main branch.

TODO: dispense with this bullshit and write an asm version.

36d6b545a1 CMOV-ify vp56 arithcoder 
This incantation causes gcc 4.3 to generate cmov on x86, a vastly better option
than a completely unpredictable branch.
Hopefully this carries over to newer versions and other CPUs with conditionals.
~5 cycles saved per call on a Core i7.

dd8e127a4d rv40: make rv40_adaptive_loop_filter() always_inline 
This function is called from the rv40_[hv]_loop_filter() wrappers
with some arguments constant, so it really needs to be inlined.
