[llvm-commits] [PATCH] optimization of max-like struct for x86

[Manman Ren]

This patch is intended to optimize the following cases for x86:
(b > a) ? (b-a) : 0
(a < b) ? (b-a) : 0
It will use cmovs in generated x86 code.

The patch modified one source file: lib/Target/X86/X86ISelLowering.cpp

Please review & provide feedback.
Thanks,
