New Revision: 274802<br>
<br>
URL: <a href="http://llvm.org/viewvc/llvm-project?rev=274802&view=rev" rel="noreferrer" target="_blank">http://llvm.org/viewvc/llvm-project?rev=274802&view=rev</a><br>
Log:<br>
Recommit r274692 - [X86] Transform setcc + movzbl into xorl + setcc<br>
<br>
xorl + setcc is generally the preferred sequence due to the partial register<br>
stall setcc + movzbl suffers from. As a bonus, it also encodes one byte smaller.<br>
This fixes PR28146.<br>
<br>
The original commit tried inserting an 8bit-subreg into a GR32 (not GR32_ABCD)<br>
which was not appreciated by fast regalloc on 32-bit.<br>
