2011-09-02Pseudo CMOV instructions don't clobber EFLAGS.Jakob Stoklund Olesen
The explanation about a 0 argument being materialized as xor is no longer valid. Rematerialization will check if EFLAGS is live before clobbering it. The code produced by X86TargetLowering::EmitLoweredSelect does not clobber EFLAGS. This causes one less testb instruction to be generated in the cmov.ll test case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139057 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-02Check for EFLAGS live-out before clobbering it.Jakob Stoklund Olesen
It is only allowed to clobber EFLAGS at the end of a block if it isn't live-in to any successor. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139056 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-02Thumb2 parsing and encoding of B instruction.Jim Grosbach
Tweak handling of IT blocks a bit to enable this. The differentiation between B and Bcc needs special sauce. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139049 91177308-0d34-0410-b5e6-96231b3b80d8
