Dave Yeo	197439c1ef	x86: pngdsp: Fix assembly for OS/2 The a.out object format does not allow aligning sections. On OS/2 LD aligns sections to 16 bytes. Signed-off-by: Diego Biurrun <diego@biurrun.de>	12 years ago
Reimar Döffinger	394d41ee30	Partially revert "Fix png decoding on x86." This partially reverts commit `58dabf7bf2`. It is no longer necessary to use unaligned mov. The swapped mov argument fix remains though.	13 years ago

Reimar Döffinger	58dabf7bf2	Fix png decoding on x86. Line sizes are only 8-byte aligned, so use unaliged loads for add_bytes_l2 pointers. Increasing the alignment requirement to 16 seemed a bit extreme (png may be used for rather small sizes). Also fix a mov that had its arguments swapped, leading add_bytes_l2 being applied on up to 8 bytes too few. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
KO Myung-Hun	c853124fb0	Use SECTION_TEXT instead of section .text for the compatibility aout does not support 'align='. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Ronald S. Bultje	af79a0c48a	png: add support for bpp>4 to paeth x86 SIMD code. This fixes playback of e.g. RGB48 (bpp=6) content on x86 CPUs. Fixes bug 214.	13 years ago
