* | avcodec/x86/hpeldsp: fix crash on AMD K6-3+Mikulas Patocka2013-11-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are instructions pavgb and pavgusb. Both instructions do the same operation but they have different enconding. Pavgb exists in SSE (or MMXEXT) instruction set and pavgusb exists in 3D-NOW instruction set. livavcodec uses the macro PAVGB to select the proper instruction. However, the function avg_pixels8_xy2 doesn't use this macro, it uses pavgb directly. As a consequence, the function avg_pixels8_xy2 crashes on AMD K6-2 and K6-3 processors, because they have pavgusb, but not pavgb. This bug seems to be introduced by commit 71155d7b4157fee44c0d3d0fc1b660ebfb9ccf46, "dsputil: x86: Convert mpeg4 qpel and dsputil avg to yasm" Signed-off-by: Mikulas Patocka <mikulas@artax.karlin.mff.cuni.cz> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
