Summary: We used to assume V->RAUW only modifies the operand list of V's user. However, if V and V's user are Constants, RAUW may replace and invalidate V's user entirely. This patch fixes the above issue by letting the caller replace the operand instead of calling RAUW on Constants. Test Plan: @nested_const_expr and @rauw in access-non-generic.ll Reviewers: broune, jholewinski Reviewed By: broune, jholewinski Subscribers: jholewinski, llvm-commits Differential Revision: http://reviews.llvm.org/D10345 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@239435 91177308-0d34-0410-b5e6-96231b3b80d8
