This patch will optimize -(x != 0) on X86 FROM cmpl $0x01,%edi sbbl %eax,%eax notl %eax TO negl %edi sbbl %eax %eax In order to generate negl, I added patterns in Target/X86/X86InstrCompiler.td: def : Pat<(X86sub_flag 0, GR32:$src), (NEG32r GR32:$src)>; rdar: 10961709 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@156312 91177308-0d34-0410-b5e6-96231b3b80d8		2012-05-07 18:06:23 +00:00
