[PATCH] Account for vector splat GPR->XMM move cost

2023-05-23 Thread Richard Biener via Gcc-patches
The following also accounts for a GPR->XMM move cost for splat operations and properly guards eliding the cost when moving from memory only for SSE4.1 or HImode or larger operands. This doesn't fix the PR fully yet. Bootstrapped and tested on x86_64-unknown-linux-gnu, OK? Thanks, Richard.
