* Partially revert "Fix png decoding on x86."Reimar Döffinger2012-02-10
| | | | | | This partially reverts commit 58dabf7bf2fdd08f79173da0df613127ff783028. It is no longer necessary to use unaligned mov. The swapped mov argument fix remains though.
* Fix png decoding on x86.Reimar Döffinger2012-02-03
| | | | | | | | | | | 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>
