* mathematics.h: remove a couple of math definesJanne Grunau2012-06-20
| | | | | | | | While these defines are not defined by the C standard they are standardized as X/Open System Interfaces Extension. We use the appropiate _XOPEN_SOURCE define to make them available. They seem to be available on all FATE configs since the constants are used in files where mathematics.h is not included.

* mips: intreadwrite: fix inline asm for gcc 4.8Mans Rullgard2012-05-09
| | | | | | | | | Just like gcc 4.6 and later on ARM, gcc 4.8 on MIPS generates inefficient code when a known-unaligned location is used as a memory input operand. This applies the same fix as has been previously done to the ARM version of the code. Signed-off-by: Mans Rullgard <mans@mansr.com>
* mips: intreadwrite: remove unnecessary inline asmMans Rullgard2012-05-09
| | | | | | | | GCC actually handles unaligned accesses correctly in all cases except, absurdly, 32-bit loads on mips64. The remaining asm is thus not needed, and removing it results in better code. Signed-off-by: Mans Rullgard <mans@mansr.com>

* arm: intreadwrite: revert 16-bit load asm to old version for gcc < 4.6Mans Rullgard2012-05-03
| | | | | | | | Commit adebad0 "arm: intreadwrite: fix inline asm constraints for gcc 4.6 and later" caused some older gcc versions to miscompile code. This reverts to the old version of the code for these compilers. Signed-off-by: Mans Rullgard <mans@mansr.com>
* arm: intreadwrite: disable inline asm for gcc 4.7 and laterMans Rullgard2012-05-02
| | | | | | | | Starting with version 4.7, gcc properly supports unaligned memory accesses on ARM. Not using the inline asm with these compilers results in better code. Signed-off-by: Mans Rullgard <mans@mansr.com>
* arm: intreadwrite: fix inline asm constraints for gcc 4.6 and laterMans Rullgard2012-05-02
| | | | | | | | | | | | | | | | | | | | With a dereferenced type-cast pointer as memory operand, gcc 4.6 and later will sometimes copy the data to a temporary location, the address of which is used as the operand value, if it thinks the target address might be misaligned. Using a pointer to a packed struct type instead does the right thing. The 16-bit case is special since the ldrh instruction addressing modes are limited compared to ldr. The "Uq" constraint produces a memory reference suitable for an ldrsb instruction, which supports the same addressing modes as ldrh. However, the restrictions appear to apply only when the operand addresses a single byte. The memory reference must thus be split into two operands each targeting one byte. Finally, the "Uq" constraint is only available in ARM mode. The Thumb-2 ldrh instruction supports most addressing modes so the normal "m" constraint can be used there.

* avutil: add av_parse_cpu_flags() functionMans Rullgard2012-04-25

* avutil: change default buffer size alignment for sample buffer functionsJustin Ruggles2012-04-23
| | | | | Aligning nb_samples will give both correct plane pointer alignment and enough padding for SIMD-optimized functions.
* ARM: allow runtime masking of CPU featuresMans Rullgard2012-04-22
| | | | | | | This allows masking CPU features with the -cpuflags avconv option which is useful for testing different optimisations without rebuilding. Signed-off-by: Mans Rullgard <mans@mansr.com>

* mem: Consistently return NULL for av_malloc(0)Martin Storsjö2012-04-10
| | | | | | | | | | | | | | | | | Plain POSIX malloc(0) is allowed to return either NULL or a non-NULL pointer. The calling code should be ready to handle a NULL return as a correct return (instead of a failure) if the size to allocate was 0 - this makes sure the condition is handled in a consistent way across platforms. This also avoids calling posix_memalign(&ptr, 32, 0) on OS X, which returns an invalid pointer (a non-NULL pointer that causes crashes when passed to av_free). Abort in debug mode, to help track down issues related to incorrect handling of this case. Signed-off-by: Martin Storsjö <martin@martin.st>
