Adhemerval Zanella	6f0993a638	powerpc: Simplify bcopy default implementation ... This patch simplify the default bcopy symbol for powerpc64 by just using memmove instead of implementing using the default bcopy. Since the symbol is deprecated, it trades speed by code size.	2015-02-09 06:42:28 -05:00

Adhemerval Zanella	17762f6625	PowerPC: optimized memmove for POWER7/PPC64 ... This patch adds an optimized memmove optimization for POWER7/powerpc64. Basically the idea is to use the memcpy for POWER7 on non-overlapped memory regions and a optimized backward memcpy for memory regions that overlap (similar to the idea of string/memmove.c). The backward memcpy algorithm used is similar the one use for memcpy for POWER7, with adjustments done for alignment. The difference is memory is always aligned to 16 bytes before using VSX/altivec instructions.	2014-07-07 15:41:21 -05:00
