[PATCH] D35994: Debug info for variables whose type is shrinked to bool

[Adrian Prantl via Phabricator via llvm-commits]

aprantl added a comment.

In fully-compliant mode we should just not emit any DWARF expression that ends with a DW_OP_stack_value in DWARF < 4. However, LLDB and GDB (at least the version Apple used to ship in Xcode) support a couple of expressions that are outside of the specification but do work in practice, so I'm reluctant to drop support for that by being stricter.
That said, Darwin has been using DWARF 4 for a while now, so an argument could be made that it is okay to regress on older deployment targets for the sake of correctness/standards compliance.
