The code that builds the dependence graph assumes that two PseudoSourceValues don't alias. In a tail calling function two FixedStackObjects might refer to the same location. Worse 'immutable' fixed stack objects like function arguments are not immutable and will be clobbered. Change this so that a load from a FixedStackObject is not invariant in a tail calling function and don't return a PseudoSourceValue for an instruction in tail calling functions when building the dependence graph so that we handle function arguments conservatively. Fix for PR23459. rdar://20740035 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@236916 91177308-0d34-0410-b5e6-96231b3b80d8 |
