* 4:4:4 H.264 decoding supportJason Garrett-Glaser2011-06-13
| | | | Note: this is 4:4:4 from the 2007 spec revision, not the previous (now deprecated) 4:4:4 mode in H.264.

* ARM: jrevdct_arm: use push/pop mnemonicsMans Rullgard2011-06-13
| | | | | | | Use push/pop instead of stmdb/ldmia for stack operations. This is the preferred syntax. Signed-off-by: Mans Rullgard <mans@mansr.com>

* ARM: remove MUL64 and MAC64 inline asmMans Rullgard2011-06-06
| | | | | | | | | | | | | Current GCC versions know how to generate these instructions properly and avoiding inline asm gives better code. The MULH function for ARMv5 uses the same instruction and is also not needed any more. The MLS64 macro remains since negating an input would normally not be allowed as it would fail for INT_MIN. In our uses, the inputs never have this value and thus negating is safe. Signed-off-by: Mans Rullgard <mans@mansr.com>
* ARM: remove MULL inline asmMans Rullgard2011-06-04
| | | | | | Reasonable gcc versions get this one right on their own. Signed-off-by: Mans Rullgard <mans@mansr.com>

* ARM: fix MUL64 inline asm for pre-armv6Mans Rullgard2011-05-31
| | | | | | | | | | | Prior to ARMv6, the destination registers of the SMULL instruction must be distinct from the first source register. Marking the output early-clobber ensures it is allocated unique registers. This restriction is dropped in ARMv6 and later, so allowing overlap between input and output registers there might give better code. Signed-off-by: Mans Rullgard <mans@mansr.com>

* ARM: enable UAL syntax in asm.SMans Rullgard2011-05-29
| | | | | | | This enables UAL syntax for all asm files instead of only those which happen to be incompatible with the old, deprecated syntax. Signed-off-by: Mans Rullgard <mans@mansr.com>

* ac3enc: modify mantissa bit counting to keep bap counts for all values of bapJustin Ruggles2011-05-28
| | | | | | instead of just 0 to 4. This does all the actual bit counting as a final step.
* ARM: aacdec: fix constraints on inline asmMans Rullgard2011-05-28
| | | | | | | This adds output operands for modified memory allowing the volatile qualifiers to be dropped. Signed-off-by: Mans Rullgard <mans@mansr.com>

* ARM: disable ff_vector_fmul_vfp on VFPv3 systemsMans Rullgard2011-05-27
| | | | | | | | | | This function uses old-style vector operations deprecated in VFPv3. Some implementations, e.g. Cortex-A9, support them only through slow software emulation. Cortex-A8 does have this functionality in hardware, but as it also has NEON, this function is not used there regardless. Signed-off-by: Mans Rullgard <mans@mansr.com>
* multiple inclusion guard cleanupDiego Biurrun2011-05-21
| | | | | Add missing multiple inclusion guards; clean up #endif comments; add missing library prefixes; keep guard names consistent.

* Adds 8-, 9- and 10-bit versions of some of the functions used by the h264 ↵Oskar Arvidsson2011-05-10
| | | | | | | | | | | | | | | | | decoder. This patch lets e.g. dsputil_init chose dsp functions with respect to the bit depth to decode. The naming scheme of bit depth dependent functions is <base name>_<bit depth>[_<prefix>] (i.e. the old clear_blocks_c is now named clear_blocks_8_c). Note: Some of the functions for high bit depth is not dependent on the bit depth, but only on the pixel size. This leaves some room for optimizing binary size. Preparatory patch for high bit depth h264 decoding support. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>

* Rearrange MpegEncContext to simplify access from asmMans Rullgard2011-01-29
| | | | | | | | | This moves the fields needed by asm near the top, before any structs or other members which complicate the offset calculation. Modifying other structs will no longer require updating the offsets, and the asm code is slightly simpler due to the smaller offsets. Signed-off-by: Mans Rullgard <mans@mansr.com>
