2013-08-05mpegts: Remove one 64-bit integer modulus operation per packetBen Avison
The common case of the pointer having increased by one packet (which results in no change to the modulus) can be detected with a 64-bit subtraction, which is far cheaper than a division on many platforms.

2012-08-09Move MASK_ABS macro to libavcodec/mathops.hMans Rullgard
This macro is only used in two places, both in libavcodec, so this is a more sensible place for it. Two small tweaks to the macro are made: - removing the trailing semicolon - dropping unnecessary 'volatile' from the x86 asm Signed-off-by: Mans Rullgard <mans@mansr.com>

2011-10-13mathops: remove undefined behaviour from sign_extend()Mans Rullgard
This function intentionally overflows the signed range on the left shift. Using this type-punning avoids errors from the overflow checker without disabling this test globally. Signed-off-by: Mans Rullgard <mans@mansr.com>
