rs6000: Enable overlapped by-pieces operations
This patch enables overlapped by-piece operations by defining
TARGET_OVERLAP_OP_BY_PIECES_P to true. On rs6000, default move/set/clear
ratio is 2. So the overlap is only enabled with compare by-pieces.
gcc/
* config/rs6000/rs6000.cc (TARGET_OVERLAP_OP_BY_PIECES_P): Define.
gcc/testsuite/
* gcc.target/powerpc/block-cmp-9.c: New.
