Martin Storsjö	570d4b2186	x86: h264: Don't keep data in the redzone across function calls on 64 bit unix We know that the called function (ff_chroma_inter_body_mmxext) doesn't touch the redzone, and thus will be kept intact - thus, this doesn't fix any bug per se. However, valgrind's memcheck tool intentionally assumes that the redzone is clobbered on every function call and function return (see a long comment in valgrind/memcheck/mc_main.c). This avoids false positives in that tool, at the cost of an extra stack pointer adjustment. The other alternative would be a valgrind suppression for this issue, but that's an extra burden for everybody that wants to run libavcodec within valgrind.

Martin Storsjö	0776e0ef6b	adpcm: Write the proper predictor in trellis mode in IMA QT The actual predictor value, set by the trellis code, never was written back into the variable that was written into the block header. This was accidentally removed in `b304244b`. This significantly improves the audio quality of the trellis case, which was plain broken since `b304244b`. Encoding IMA QT with trellis still actually gives a slightly worse quality than without trellis, since the trellis encoder doesn't use the exact same way of rounding as in adpcm_ima_qt_compress_sample and adpcm_ima_qt_expand_nibble.
