5e826fd65e ARM: set Tag_ABI_align_preserved in all asm files
All our ARM asm preserves alignment so setting this attribute
in a common location is simpler.  This removes numerous warnings
when linking with armcc.

e6cd698955 ARMv6: vp8: fix stack allocation with Apple's assembler

9829a81bcd ARM: vp56: allow inline asm to build with clang
The clang integrated assembler does not support pre-UAL syntax,
while gcc requires pre-UAL syntax for ARM code.  A patch[1] for
clang to support the old syntax as well has been ignored since
January.

This patch chooses the syntax appropriate for each compiler,
allowing both to build the code.  Notably, this change allows
building for iphone with the latest Apple Xcode update.

272b252c01 rv40dsp: implement prescaled versions for biweight.
Quite often, the original weights are multiple of 512. By prescaling them
by 1/512 when they are computed (once per frame), no intermediate shifting
is needed, and no prescaling on each call either.

The x86 code already used that trick.

21c6512542 ARM: remove MUL64 and MAC64 inline asm
Current GCC versions know how to generate these instructions
properly and avoiding inline asm gives better code.  The MULH
function for ARMv5 uses the same instruction and is also not
needed any more.

The MLS64 macro remains since negating an input would normally
not be allowed as it would fail for INT_MIN.  In our uses, the
inputs never have this value and thus negating is safe.

c51695dbf6 ARM: fix MUL64 inline asm for pre-armv6
Prior to ARMv6, the destination registers of the SMULL instruction
must be distinct from the first source register.  Marking the
output early-clobber ensures it is allocated unique registers.

This restriction is dropped in ARMv6 and later, so allowing overlap
between input and output registers there might give better code.

b27b54de31 arm/h264pred: add missing argument type. 2011-05-10 08:44:49 -04:00
Oskar Arvidsson
19a0729b4c Adds 8-, 9- and 10-bit versions of some of the functions used by the h264 decoder.
This patch lets e.g. dsputil_init chose dsp functions with respect to
the bit depth to decode. The naming scheme of bit depth dependent
functions is <base name>_<bit depth>[_<prefix>] (i.e. the old
clear_blocks_c is now named clear_blocks_8_c).

Note: Some of the functions for high bit depth is not dependent on the
bit depth, but only on the pixel size. This leaves some room for
optimizing binary size.

Preparatory patch for high bit depth h264 decoding support.

4693b031a3 Move H264 dsputil functions into their own struct
This moves the H264-specific functions from DSPContext to the new
H264DSPContext.  The code is made conditional on CONFIG_H264DSP
which is set by the codecs requiring it.

The qpel and chroma MC functions are not moved as these are used by
non-h264 code.
