Ronald S. Bultje	96c9cc1094	x86inc: sync to latest version from x264.	12 years ago
Justin Ruggles	79687079a9	x86: add support for fmaddps fma4 instruction with abstraction to avx/sse	12 years ago
Ronald S. Bultje	02ac28229a	eval: fix printing of NaN in eval fate test. This fixes "make fate-eval" on MSVC builds. Without this, the test outputs "-1.#NaN" instead of "nan" on MSVS 2010.	12 years ago

Martin Storsjö	620b1e7e98	mem: Don't abort on av_malloc(0) in debug mode This makes the behaviour consistent between debug and release mode. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago

Loren Merritt	2cd1f5cadc	x86inc: modify ALIGN to not generate long nops on i586 Signed-off-by: Diego Biurrun <diego@biurrun.de>	13 years ago
Samuel Pitoiset	983db9b2b4	xtea: Make the count parameter match the documentation Previously it was interpreted as number of bytes, while the documentation stated that it was the number of 8 byte blocks. This makes it behave similarly to the existing AES code. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Samuel Pitoiset	e4a7fb3da3	blowfish: Make the count parameter match the documentation Previously it was interpreted as number of bytes, while the documentation stated that it was the number of 8 byte blocks.

Luca Barbato	f6687bf5f8	xtea: invert branch and loop precedence Should slightly improve performance depending on the compiler used.	13 years ago

Diego Biurrun	1a068bfefd	cosmetics: Consistently use C-style comments with multiple inclusion guards	13 years ago
Reinhard Tartler	22662ca560	attributes: add av_noreturn Also use it in the declaration of the various exit_program implementations in avtools. inspired by a clang-scan report.	13 years ago
Reinhard Tartler	a1641e9540	attributes: drop pointless define guards the av_-prefixed attributes must not be defined outside of this file	13 years ago
Ronald S. Bultje	ff8f8dfb79	intfloat: Don't use designated initializers in the public headers intfloat.h is a public header, and is now (since `a1245d5ca`) included by mathematics.h, which many external callers include. This fixes building third party applications that include mathematics.h in a language that doesn't support designated initalizers. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Martin Storsjö	3893feeccd	opt/eval: Include mathematics.h for NAN/INFINITY These files use NAN/INFINITY but didn't include mathematics.h to get the fallback definitions if the system lacks the macros. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Ronald S. Bultje	a1245d5ca1	mathematics: Don't use division by zero in NAN/INFINITY macros Some compilers, MSVC among them, don't recognize the divisions by zero as meaning infinity/nan. These macros should, according to the standard, expand to constant expressions, but this shouldn't matter for our usage. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Mans Rullgard	889c1ec4cc	x86: cpu: clean up check for cpuid instruction support This adds macros for accessing the EFLAGS register and uses these instead of coding the entire check in inline asm. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	62634158b7	ARM: generate position independent code to access data symbols This creates proper position independent code when accessing data symbols if CONFIG_PIC is set. References to external symbols should now use the movrelx macro. Some additional code changes are required since this macro may need a register to hold the GOT pointer. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Ronald S. Bultje	4f2c846d96	attributes: Add a definition of av_always_inline for MSVC Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Ronald S. Bultje	f985113075	random_seed: Only read /dev/random if we have unistd.h unistd.h is used for open/read/close, but if this header does not exist, there's probably no use in trying to open /dev/random at all. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Martin Storsjö	46df708b45	libm: Provide fallback definitions for isnan() and isinf() Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Mans Rullgard	153335625c	libm: provide fallback definition for cbrtf() using powf() This adds a fallback for cbrtf() using powf(x, 1/3). Since powf() with a non-integer exponent requires a non-negative base, special handling of negative inputs is needed. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Ronald S. Bultje	246154a9af	log: Include io.h on windows This is required for isatty, which exists on MSVC and is found by configure, but is provided by io.h instead of unistd.h. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Mans Rullgard	963cdf39b4	x86: cpu: whitespace (mostly) cosmetics This adds whitespace around operators, aligns line continuation backslashes, and breaks long lines. Also fixes an ifdef halfway through a statement. The one line of duplication this saved is not worth the ugliness. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Ronald S. Bultje	8123e0901f	x86: place some inline asm under #if HAVE_INLINE_ASM Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Martin Storsjö	145a8096d5	log: Only include unistd.h if configure found it MSVC has isatty (in io.h), but not unistd.h. (isatty isn't called at all for windows, since there's a special case block for that.) Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Diego Biurrun	65345a5a30	x86: Add CPU flag for the i686 cmov instruction	13 years ago
Mans Rullgard	d3d3a32c9d	lavu: add av_usleep() function This function implements a delay using the first available of the following functions: - nanosleep() - usleep() - Sleep() (Windows) The conditional #includes in time.c are simplified by including unistd.h and windows.h whenever they are available rather than having these lines triggered by specific functions. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Diego Biurrun	a5a93fa8f5	cosmetics: do not use full path for local headers	13 years ago
Mans Rullgard	d11baad055	lavu/file: include unistd.h only when available The unistd.h header is only needed for the close() declaration. If this header is not available, the close() declaration may be provided by another header, e.g. io.h. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	539df61193	log: include unistd.h only when needed The only symbol this file uses from unistd.h is isatty(). By including the header only when this function is used, the file can be built on systems without unistd.h (which presumably also lack isatty). Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	dc7e336cae	lavf, lavu: version bumps and APIchanges for av_gettime() move Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
