This new pass eliminate identical move: MOV rA, rA This is particularly possible to happen when sub-register support enabled. The special type cast insn MOV_32_64 involves different register class on src (i32) and dst (i64), RA could generate useless instruction due to this. This pass also could serve as the bast for further post-RA optimization. Signed-off-by: Jiong Wang <jiong.wang@netronome.com> Signed-off-by: Yonghong Song <yhs@fb.com> llvm-svn: 327370 |
