* | [X86] Improve EmitLoweredSelect for contiguous CMOV pseudo instructions. | Michael Kuperstein | 2015-08-06 | 1 | -0/+267 |
This change improves EmitLoweredSelect() so that multiple contiguous CMOV pseudo instructions with the same (or exactly opposite) conditions get lowered using a single new basic-block. This eliminates unnecessary extra basic-blocks (and CFG merge points) when contiguous CMOVs are being lowered.
