* Rather than having special rules like "intrinsics cannotDuncan Sands2007-12-031-1/+1
| | | | | | | | | | 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
* Integrate the readonly/readnone logic more deeplyDuncan Sands2007-12-011-1/+1
| | | | | | | | | | | | | | | | 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
