* arm: check if AS supports .dnJanne Grunau2014-06-03
| | | | | | | | | | | | Move the GNU as check before the arch specific asm checks since the .dn check requires gas compatible assembler. Disable the VC-1 motion compensation NEON asm which is the only part using that directive. The integrated assembler in the upcoming clang 3.5 does not support .dn/.qn without plans to change that. Too much effort to implement it while it is rarely used. http://llvm.org/bugs/show_bug.cgi?id=18199.

| | | | | | | | The function is assigned to a function pointer that does not have the restrict keyword for that parameter. This fixes compilation for MSVC builds that don't recognize "restrict", broken since ed9625eb62.

* armv6: vp8: use explicit labels in motion compensation asmJanne Grunau2014-03-12
| | | | | The integrated arm assembler in clang-503.0.38 (Xcode-5.1) fails to assemble a branch to 'label + offset' in thumb mode.
* arm: get_cabac inline asmJanne Grunau2014-03-09
| | | | | | | | | | Based on the aarch64 asm. CPU cycle counts on cortex-a9 compared to gcc 4.8.2: before: 475 decicycles in get_cabac_noinline, 67106035 runs, 2829 skips after: 393 decicycles in get_cabac_noinline, 67106474 runs, 2390 skips Overall speedup is above 2%. Code generated by clang 3.4 is slower on the same hardware and the relative change is a little larger.

| | | | | | | | The overread avoidance fix in cbddee1cca0ebd01e8c5aa694d31228eb4de4b41 broke the computation for the last row since it prevented the safe reading from the height+1-th row. CC: libav-stable@libav.org

* arm: dcadsp: implement decode_hf as external NEON asmJanne Grunau2014-02-28

* dcadec: simplify decoding of VQ high frequenciesChristophe Gisquet2014-02-28
| | | | | | | | | | | | | | | | | | | The vector dequantization has a test in a loop preventing effective SIMD implementation. By moving it out of the loop, this loop can be DSPized. Therefore, modify the current DSP implementation. In particular, the DSP implementation no longer has to handle null loop sizes. The decode_hf implementations have following timings: For x86 Arrandale: C SSE SSE2 SSE4 win32: 260 162 119 104 win64: 242 N/A 89 72 The arm NEON optimizations follow in a later patch as external asm. The now unused check for the y modifier in arm inline asm is removed from configure.

* dcadsp: split lfe_dir casesChristophe Gisquet2014-02-07
| | | | | | | | | The x86 runs short on registers because numerous elements are not static. In addition, splitting them allows more optimized code, at least for x86. Arm asm changes by Janne Grunau. Signed-off-by: Janne Grunau <janne-libav@jannau.net>
* dcadsp: add int8x8_fmul_int32 to dsp contextChristophe Gisquet2014-02-07
| | | | | | | | | | | | | | It is currently declared as a macro who is set to inlinable functions, among which a Neon and a default C implementations. Add a DSP parameter to each inline function, unused except by the default C implementation which calls a function from the DSP context. On an Arrandale CPU, gain for an inlined SSE2 function vs. a call: - Win32: 29 to 26 cycles - Win64: 25 to 23 cycles Signed-off-by: Janne Grunau <janne-libav@jannau.net>

* arm: Allow overriding the alignment set in the function macroMartin Storsjö2014-01-07
| | | | | | | | | | | | | | | The function macro always sets .align 2 before declaring the function label (since 5c5e1ea3) and always sets the section to .text (since 278caa6a). The .align 5 before certain functions, added in fc252eba, were added before .text and .align were added to the function macro and thus became useless/unused when the function macro got them. This restores the original intention, to align the loop entry points. Signed-off-by: Martin Storsjö <martin@martin.st>
