- Override <memcopy.h> so we use full 8-byte word copies on tilegx32 for memmove, then use op_t in memcpy instead of the previous locally-defined word_t just to avoid proliferating identical types. - Fix bug in memcpy prefetch that caused us to never prefetch past the first cache line. - Optimize misaligned memcpy by inlining _wordcopy_fwd_dest_aligned instead of just doing a dumb word-at-a-time copy. - Make memcpy safe for forward copies by doing all the loads from a given cache line prior to doing a wh64 (cache line zero-fill) on the destination. Remove now-redundant src == dst check. - Copy and optimize the generic wordcopy.c routines to use the tile "double align" instruction instead of the MERGE macro; to avoid offset addressing mode (which tile doesn't have) by rewriting the pointer math to load and store with a zero index; and to use post-increment addresses in the inner loops to improve scheduling. |
