Piotr Padlewski 04aee46779 Remove readnone from invariant.group.barrier ... Summary: Readnone attribute would cause CSE of two barriers with the same argument, which is invalid by example: struct Base { virtual int foo() { return 42; } }; struct Derived1 : Base { int foo() override { return 50; } }; struct Derived2 : Base { int foo() override { return 100; } }; void foo() { Base *x = new Base{}; new (x) Derived1{}; int a = std::launder(x)->foo(); new (x) Derived2{}; int b = std::launder(x)->foo(); } Here 2 calls of std::launder will produce @llvm.invariant.group.barrier, which would be merged into one call, causing devirtualization to devirtualize second call into Derived1::foo() instead of Derived2::foo() Reviewers: chandlerc, dberlin, hfinkel Subscribers: llvm-commits, rsmith, amharc Differential Revision: https://reviews.llvm.org/D31531 llvm-svn: 300101		2017-04-12 20:45:12 +00:00
