Martin Storsjö	cdb1665f70	aarch64: Make transpose_4x4H do a regular transpose Previously, ff_h264_idct_add_neon (originally in the arm version) used a non-regular transpose in order to be able to use more instructions that deal with registers as 128 bit register pairs. The aarch64 translation doesn't do it to the same extent, but brought along the same structure since it was a straight translation. This reshuffles ff_h264_idct_add_neon, bringing it closer to the C implementation, making the transpose_4x4H macro do a regular transpose, usable for other algorithms as well. Previously, the third and fourth output from transpose_4x4H were swapped, and prior to `cc29d96d5a`, the same inputs as well. In addition to just swapping the outputs, also renumber the intermediate registers for better readability (making the register order match transpose_4x8B). This runs with the same number of cycles as before. Signed-off-by: Martin Storsjö <martin@martin.st>	9 years ago

Janne Grunau	a0fc780a20	arm64: int32_to_float_fmul neon asm 3% faster dts decoding on a cortex-a57. cortex-a57 cortex-a53 int32_to_float_fmul_array8_c: 1270.9 4475.6 int32_to_float_fmul_array8_neon: 328.6 569.2 int32_to_float_fmul_scalar_c: 928.5 4119.6 int32_to_float_fmul_scalar_neon: 309.1 524.1	9 years ago
Janne Grunau	705f5e5e15	arm64: port synth_filter_float_neon from arm ~25% faster dts decoding overall.

Janne Grunau	ac6b95dbc0	aarch64: add ',' between assembler macro arguments where missing llvm's integrated assembler does not accept spaces as macro argument delimiter when targeting darwin. Using a explicit delimiter is a good idea in principle since it makes case like 'macro 4 -2' vs 'macro 4 - 2' clear.	11 years ago

Janne Grunau	dfe224f377	aarch64: get_cabac inline asm Based on the x86 branchless get_cabac asm. get_cabac_noinline() gets approximately 20% faster (no cycle counts available) compared to clang from Xcode 5.1 beta5. More than 6% faster overall. A part of the overall speedup might be explained by additional inlining of get_cabac().	11 years ago
