* parseutils: fix parsing of invalid alpha valuesMans Rullgard2012-10-06
| | | | | | | | | | An alpha specifier outside the valid range results in a conversion from double to long with undefined result. Range-checking the double and only converting it after it passes avoids this. Fixes fate-parseutils errors on some systems. Signed-off-by: Mans Rullgard <mans@mansr.com>
* Give all anonymously typedeffed structs in headers a nameDiego Biurrun2012-10-06
| | | | Anonymous structs cannot be forward declared and have no benefit.
* parseutils-test: Drop random colors from parsing testDiego Biurrun2012-10-06
| | | | This guarantees stable output for comparing test results.
* x86: get_cpu_flags: add necessary ifdefs around function bodyDiego Biurrun2012-10-04
| | | | | | | ff_get_cpu_flags_x86() requires cpuid(), which is conditionally defined elsewhere in the file. Surrounding the function body with ifdefs allows building even when cpuid is not defined. An empty cpuflags mask is returned in this case.
* x86: Drop CPU detection intrinsicsDiego Biurrun2012-10-04
| | | | | | Now that there is CPU detection in YASM, there will always be one of inline or external assembly enabled, which obviates the need to fall back on CPU detection through compiler intrinsics.
* x86: Add YASM implementations of cpuid and xgetbv from x264Diego Biurrun2012-10-04
| | | | | This allows detecting CPU features with builds that have neither gcc inline assembly nor the right compiler intrinsics enabled.

* samplefmt: make av_samples_alloc() initialize the data to silence.Anton Khirnov2012-10-04
| | | | Right now the buffer is zeroed, which does not represent silence for U8(P).

* Allow use of strncpy()Mans Rullgard2012-10-03
| | | | | | | | There are cases where strncpy() does exactly what is required. A blanket ban forces more convoluted solutions to be used in those cases and has been a cause of bugs. Signed-off-by: Mans Rullgard <mans@mansr.com>

* ARM: use numeric ID for Tag_ABI_align_preservedMans Rullgard2012-10-03

* ARM: bswap: drop armcc version of av_bswap16()Mans Rullgard2012-10-02
| | | | | | | This function causes several versions of armcc to miscompile code, and the performance impact is small. Signed-off-by: Mans Rullgard <mans@mansr.com>
* ARM: set Tag_ABI_align_preserved in all asm filesMans Rullgard2012-10-02
| | | | | | | | All our ARM asm preserves alignment so setting this attribute in a common location is simpler. This removes numerous warnings when linking with armcc. Signed-off-by: Mans Rullgard <mans@mansr.com>
* ARM: fix Thumb PIC on AppleMans Rullgard2012-10-02
| | | | | | | LDR with register offset and PC as base register is not available in the Thumb instruction set so the addition must be done separately. Signed-off-by: Mans Rullgard <mans@mansr.com>

* ARM: use 2-operand syntax for ADD Rd, PC in Apple PIC codeMans Rullgard2012-09-21
| | | | | | | The Apple assembler refuses to assemble the 3-operand form in Thumb2 even though it is valid syntax. Signed-off-by: Mans Rullgard <mans@mansr.com>
* ARM: align PIC offset pools to 4 bytesMans Rullgard2012-09-21
| | | | | | | | | When building Thumb2 code, the end of a function, where the PIC offsets are placed, need not be aligned. Although the values are only accessed with instructions allowing unaligned addresses, keeping them aligned is preferable. Signed-off-by: Mans Rullgard <mans@mansr.com>
* ARM: swap source operands in some add instructionsMans Rullgard2012-09-20

* x86: remove FASTDIV inline asmMans Rullgard2012-08-22
| | | | | | | | | | | | | | | | | | | GCC 4.3 and later do the right thing with the plain C code. Earlier versions in 32-bit mode generate one extra instruction, needlessly zeroing what would be the high half of the shifted value. At least two gcc configurations miscompile the inline asm in some situations. In 64-bit mode, all gcc versions generate imul r64, r64 followed by shr. On Intel i7 and later, this imul is faster 32-bit mul. On older Intel and all AMD, it is slightly slower. On Atom it is much slower. Considering where the FASTDIV macro is used, any overall negative performance impact of this change should be negligible. If anyone cares, they should file a bug against gcc and get the instruction selection fixed. Signed-off-by: Mans Rullgard <mans@mansr.com>
* configure: Drop fastdiv optionDiego Biurrun2012-08-22
| | | | | | There is no point in having the user disable any fastdiv macros. Besides the condition implementation was broken and only disabled the C implementation, but no platform specific assembly versions.
