<p class="MsoNormal">This patch aims to improve compile time
performance by increasing the SCEV vector size in
LoopStrengthReduce. It is observed that the BaseRegs vector
size is 4 in most cases, and elements are frequently copied
when it is initialized as
<span style="font-size:10.5pt;mso-fareast-language:ZH-CN">SmallVector<const
SCEV *, 2> BaseRegs.<o:p></o:p></span></p>
<p class="MsoNormal"><span
style="font-size:10.5pt;mso-fareast-language:ZH-CN">Our
benchmark results show that the compilation time performance
improved by ~0.5%.</span></p>

Just an FYI that I think patches are supposed to be sent to
llvm-commits.<br>
