Mikhail Nitenko	756d2e087a	lavc/aarch64: move transpose_4x8H to neon.S transpose_4x8H was declared in vp9lpf_16bpp_neon, however this macro is not unique to vp9 and could be used elsewhere.

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

Michael Niedermayer	95b59bfb9d	Revert "avcodec/aarch64/neon.S: Update neon.s for transpose_4x4H" The change was not correct and broke H264 This reverts commit `cd83f899c9`.	9 years ago
zjh8890	c18176bd55	avcodec/aarch64/neon.S: Update neon.s for transpose_4x4H The transpose_4x4H is wrong which cost me much time to find this bug. The orders of r2 and r3 are wrong, this bug waste me much time while I make aarch64 arm instruction which used the function.	9 years ago
