* [AArch64] Reverting recent optimized memset().Marcus Shawcroft2015-07-151-184/+191

* [AArch64] Optimized memset.Wilco Dijkstra2015-07-131-191/+184
| | | | | | | | | | | This is an optimized memset for AArch64. Memset is split into 4 main cases: small sets of up to 16 bytes, medium of 16..96 bytes which are fully unrolled. Large memsets of more than 96 bytes align the destination and use an unrolled loop processing 64 bytes per iteration. Memsets of zero of more than 256 use the dc zva instruction, and there are faster versions for the common ZVA sizes 64 or 128. STP of Q registers is used to reduce codesize without loss of performance.
* [AArch64] Optimized memcpy.Wilco Dijkstra2015-07-131-134/+161
| | | | | | | | | | This is an optimized memcpy for AArch64. Copies are split into 3 main cases: small copies of up to 16 bytes, medium copies of 17..96 bytes which are fully unrolled. Large copies of more than 96 bytes align the destination and use an unrolled loop processing 64 bytes per iteration. In order to share code with memmove, small and medium copies read all data before writing, allowing any kind of overlap. On a random copy test memcpy is 40.8% faster on A57 and 28.4% on A53.
* [AArch64] Optimized memmove.Wilco Dijkstra2015-07-131-282/+108
| | | | | | | This is an optimized memmove for AArch64. All copies of up to 96 bytes and all backward copies are done by the new memcpy. The only remaining case is large forward copies which are done in the same way as the memcpy loop, but copying from the end rather than the start.
