Michael Niedermayer	fbc472da29	avutil/mem: simplify av_reallocp_array() by using av_realloc_f() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Martin Storsjö	fc962d4e7a	mem: Add av_realloc_array and av_reallocp_array These help avoiding overflows and simplify error handling. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Michael Niedermayer	636c2dd438	avutil/sha: reorder Maj arguments about 1% speedup Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Diego Biurrun	f0ce1d9909	cpu: Restructure code to avoid pointless ret variable indirection libavutil/cpu.c:133:9: warning: unused variable ‘ret’ [-Wunused-variable]	12 years ago
Michael Niedermayer	09d6beee24	avutil/sha512: Reshuffle Maj() operands This reduces dependancy chains and improves speed by about 2% Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
James Almer	682b2273e8	lavu: Add SHA-2 512 hashing Signed-off-by: James Almer <jamrial@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
James Almer	c485c835fe	avutil/crc: Dont limit CRC32 standard tables Currently, standard tables like AV_CRC_32_IEEE and such are being generated (or provided in case the user compiles with hardcoded tables) with only 257 elements. We're missing a considerable boost in performance by not making them with a size of 1024 elements instead. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	887d74c47e	av_d2q: Add a special case for \|value\| > MAX and \|value\| < 1/MAX Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Reimar Döffinger	4c2b3f4738	Add AV_HASH_MAX_SIZE. Makes it easier to use static allocation for the result buffer. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	12 years ago
Martin Storsjö	be7952b5c3	arm: Only output eabi attributes if building for ELF This matches the other eabi attribute in the same file. This is required in order to build for arm/hardfloat with other object file formats than ELF. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago

Michael Niedermayer	de7d290631	av_d2q: Fix infinity check The old check would fail on huge but not infinite values and the later code could then fail to handle them correctly in some cases. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Clément Bœsch	cf6ed1f129	lavu/opencl: remove semi-colon from macro. Fixes compilation when the macros are empty and the label above ends up containing no statement. Also makes usage of these macro consistent (some already have a semi colon, some others don't). Fixes Ticket #2603	12 years ago
Anton Khirnov	2a6eaeaa85	Move get_logical_cpus() from lavc/pthread to lavu/cpu. It will be useful in lavfi, and could conceivably be useful to the user applications as well.	12 years ago

Michael Niedermayer	9c49d5908d	avutil/hmac: silence pointer type warnings Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Giorgio Vazzana	d0a34aeedf	md5: optimize second round by using 4-operation form of G() 4-operation form is preferred over 3-operation because it breaks a long dependency chain, thus allowing a superscalar processor to execute more operations in parallel. The idea was taken from: http://www.zorinaq.com/papers/md5-amd64.html AMD Athlon(tm) II X3 450 Processor, x86_64 $ for i in $(seq 1 4); do ./avutil_md5_test2; done size: 1048576 runs: 1024 time: 5.821 +- 0.019 size: 1048576 runs: 1024 time: 5.822 +- 0.019 size: 1048576 runs: 1024 time: 5.841 +- 0.018 size: 1048576 runs: 1024 time: 5.821 +- 0.018 $ for i in $(seq 1 4); do ./avutil_md5_test2; done size: 1048576 runs: 1024 time: 5.646 +- 0.019 size: 1048576 runs: 1024 time: 5.646 +- 0.018 size: 1048576 runs: 1024 time: 5.642 +- 0.019 size: 1048576 runs: 1024 time: 5.641 +- 0.019 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
