2007-12-05- Mark last use of a split interval as kill instead of letting spiller track it.Evan Cheng
This allows an important optimization to be re-enabled. - If all uses / defs of a split interval can be folded, give the interval a low spill weight so it would not be picked in case spilling is needed (avoid pushing other intervals in the same BB to be spilled). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44601 91177308-0d34-0410-b5e6-96231b3b80d8

2007-12-03Rather than having special rules like "intrinsics cannotDuncan Sands
throw exceptions", just mark intrinsics with the nounwind attribute. Likewise, mark intrinsics as readnone/readonly and get rid of special aliasing logic (which didn't use anything more than this anyway). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44544 91177308-0d34-0410-b5e6-96231b3b80d8

2007-12-01Integrate the readonly/readnone logic more deeplyDuncan Sands
into alias analysis. This meant updating the API which now has versions of the getModRefBehavior, doesNotAccessMemory and onlyReadsMemory methods which take a callsite parameter. These should be used unless the callsite is not known, since in general they can do a better job than the versions that take a function. Also, users should no longer call the version of getModRefBehavior that takes both a function and a callsite. To reduce the chance of misuse it is now protected. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44487 91177308-0d34-0410-b5e6-96231b3b80d8
