Dan Gohman 8ca83b4111 Remove the folding rule ... getelementptr (i8* inttoptr (i64 1 to i8*), i32 -1) to inttoptr (i64 0 to i8*) from the VMCore constant folder. It didn't handle sign-extension properly in the case where the source integer is smaller than a pointer size. And, it relied on an assumption about sizeof(i8). The Analysis constant folder still folds these kinds of things; it has access to TargetData, so it can do them right. Add a testcase which tests that the VMCore constant folder doesn't miscompile this, and that the Analysis folder does fold it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94750 91177308-0d34-0410-b5e6-96231b3b80d8		2010-01-28 18:08:26 +00:00
