[PATCH] D79306: llvm rejects DWARF operator DW_OP_push_object_address.

[Adrian Prantl via Phabricator via llvm-commits]

aprantl added a comment.

Can you explain in more detail how flang is going to use this? In LLVM DIExpressions expressions we currently never refer to the SSA values that are bound to the expression via a dbg.value/dbg.declare from within the expression. We've had discussions about how to do this in the past (see https://reviews.llvm.org/D70642 and the discussions preceding it) and I would like to make sure that this fits well into the design.

It would be particularly helpful if you could post example LLVM IR that would be produced by flang to make use of this feature and the DWARF that should be generated from it.
