Mans Rullgard	5c5e1ea3cd	ARM: 4-byte align start of all asm functions Due to apprent bugs in the GNU assembler and/or linker, relocations can be incorrectly processed if the alignment of a Thumb instruction is changed in the output file compared to the input object. This fixes crashes in h264 decoding with Thumb enabled. No effect in ARM mode since everything is 4-byte aligned there. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago

Janne Grunau	e1e369049e	rv34: NEON optimised dc only inverse transform 30-50% faster than the C implementation, 0.5% overall speedup on bourne.rmvb.	13 years ago
Christophe GISQUET	98f24ecd6c	rv34: joint coefficient decoding and dequantization Perform dequantization while decoding coefficients instead of performing it on the entire coefficients buffer. Since quantized coefficients are very sparse, this usually causes a small speedup. Speedup of around 1% on Panda board compared to the removed here neon code. Global speedup is probably around 3%.

Mans Rullgard	00a856e3f9	dca: ARMv6 optimised decode_blockcode() This is a hand-tuned version of the code with impossible parts of the FASTDIV function ommitted. 2-5% faster overall on Cortex-A8. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	3a0b72dee0	ARM: remove needless .text/.align directives The 'function' macro already includes the appropriate directives. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	8ee2b4672f	ARM: add explicit .arch and .fpu directives to asm.S This prevents build errors when compiler and assembler default targets differ. Ideally each file would declare the highest level it requires. This is however not easily possible as it complicates assembling pre-armv6t2 code in Thumb-2 mode. HAVE_NEON is used as indicator for ARMv7-A since no other symbol exists for this and NEON is only available in this variant. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
