[PATCH] D29672: [DebugInfo] Make legal and emit DW_OP_swap and DW_OP_xderef

[Adrian Prantl via Phabricator via llvm-commits]

aprantl added a comment.

I'd like to request one more feature:

isValid() should reject

  !DIExpression(DW_OP_swap)

because there is only one (implicit) element on the stack.
