* random_seed: Only read /dev/*random if we have unistd.hRonald S. Bultje2012-06-29
| | | | | | | | 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>
* libm: Provide fallback definitions for isnan() and isinf()Martin Storsjö2012-06-27
| | | | Signed-off-by: Martin Storsjö <martin@martin.st>
* libm: provide fallback definition for cbrtf() using powf()Mans Rullgard2012-06-26
| | | | | | | | 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>
* log: Include io.h on windowsRonald S. Bultje2012-06-25
| | | | | | | 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>
* x86: cpu: whitespace (mostly) cosmeticsMans Rullgard2012-06-25
| | | | | | | | | 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>
* x86: place some inline asm under #if HAVE_INLINE_ASMRonald S. Bultje2012-06-25

* log: Only include unistd.h if configure found itMartin Storsjö2012-06-24
| | | | | | | 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>

* lavu: add av_usleep() functionMans Rullgard2012-06-22
| | | | | | | | | | | | | | | 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.

* lavu/file: include unistd.h only when availableMans Rullgard2012-06-21
| | | | | | | | 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>
* log: include unistd.h only when neededMans Rullgard2012-06-21
| | | | | | | | | 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>

* 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.

* mem: add support for _aligned_malloc() as found on WindowsRonald S. Bultje2012-06-19
| | | | | | | | The check uses check_func_header, since this function is conditionally available depending on the targeted MSVCRT version. Signed-off-by: Martin Storsjö <martin@martin.st>

* 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.
