Mans Rullgard	e897a633cd	ARM: factor some repetitive code into macros Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Jason Garrett-Glaser	c90b94424c	4:4:4 H.264 decoding support Note: this is 4:4:4 from the 2007 spec revision, not the previous (now deprecated) 4:4:4 mode in H.264.	14 years ago
Mans Rullgard	9776e25db9	ARM: jrevdct_arm: simplify stack usage Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	13743c7ab0	ARM: jrevdct_arm: use push/pop mnemonics Use push/pop instead of stmdb/ldmia for stack operations. This is the preferred syntax. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	77cdfde73e	ARM: jrevdct_arm: misc cleanup - use 'const' macro to define coeff table - add missing endfunc - remove superflous directives Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	5c46ad1da0	ARM: optimised mpadsp_apply_window_fixed Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	21c6512542	ARM: remove MUL64 and MAC64 inline asm 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>	14 years ago
Mans Rullgard	594fbe42c6	ARM: remove MULL inline asm Reasonable gcc versions get this one right on their own. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	8e112df409	ARM: ac3dsp: optimised update_bap_counts() Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	c51695dbf6	ARM: fix MUL64 inline asm for pre-armv6 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>	14 years ago
Mans Rullgard	6bb70dfd74	ARM: simplify inline asm with 64-bit operands Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	371266daa3	ARM: enable UAL syntax in asm.S 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>	14 years ago
Mans Rullgard	edfa89b260	ARM: unbreak build Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Justin Ruggles	6ca23db9cc	ac3enc: modify mantissa bit counting to keep bap counts for all values of bap instead of just 0 to 4. This does all the actual bit counting as a final step.	14 years ago
Mans Rullgard	7d8c17b5f6	ARM: aacdec: fix constraints on inline asm This adds output operands for modified memory allowing the volatile qualifiers to be dropped. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	84e4804ad0	ARM: remove unnecessary volatile from inline asm Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	5726ec171b	ARM: add "cc" clobbers to inline asm where needed Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	79aeade6f6	ARM: disable ff_vector_fmul_vfp on VFPv3 systems 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>	14 years ago

Ronald S. Bultje	b27b54de31	arm/h264pred: add missing argument type.	14 years ago
Oskar Arvidsson	19a0729b4c	Adds 8-, 9- and 10-bit versions of some of the functions used by the h264 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>	14 years ago

Mans Rullgard	d461a47317	Rearrange MpegEncContext to simplify access from asm 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>	14 years ago
