| | | | | | | | - Drop support for X >u 0, it's equivalent to X != 0 and should be canonicalized into the latter. - Add X < 1 -> unlikely, which is what instcombine canonicalizes X <= 0 into. - Add X > -1 -> likely, which is what instcombine canonicalizes X >= 0 into. llvm-svn: 139110

* Fix a truly heinous bug in DAGCombine related to AssertZext.Owen Anderson2011-09-031-7/+6
| | | | | | | If we have a chain of zext -> assert_zext -> zext -> use, the first zext would get simplified away because of the later zext, and then the later zext would get simplified away because of the assert. The solution is to teach SimplifyDemandedBits that assert_zext demands all of the high bits of its input, rather than only those demanded by its users. No testcase because the only example I have manifests as llvm-gcc miscompiling LLVM, and I haven't found a smaller case that reproduces this problem. Fixes <rdar://problem/10063365>. llvm-svn: 139059

* Pseudo CMOV instructions don't clobber EFLAGS.Jakob Stoklund Olesen2011-09-023-19/+9
| | | | | | | | | | | | | | The explanation about a 0 argument being materialized as xor is no longer valid.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. llvm-svn: 139057
* Check for EFLAGS live-out before clobbering it.Jakob Stoklund Olesen2011-09-021-8/+10
| | | | | | | It is only allowed to clobber EFLAGS at the end of a block if it isn't live-in to any successor. llvm-svn: 139056
