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.

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.

slow software emulation. Cortex-A8 does have this functionality
in hardware, but as it also has NEON, this function is not used

2011-05-10 08:44:49 -04:00
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.
