Mans Rullgard	6308729e68	ARM: check for inline asm 'y' operand modifier support The inline asm added in `bf5d46d` uses the 'y' modifier which is only supported from gcc 4.5. This check allows building with older compilers. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago

Mans Rullgard	fce1e43410	ARM: workaround for bug in GNU assembler Some versions of the GNU assembler do not handle 64-bit immediate operands containing arithmetic. Writing the value out in full works correctly. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	3824ef08e0	ARM: allow unaligned buffer in fixed-point NEON FFT4 This function is called with only 8-byte alignment from imdct for size 16. The fft4 function is not called for the larger FFT or MDCT sizes, so this has no impact on typical uses. 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	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	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
