* Print `ReturnLoc`, `ReturnVal`, and `ThisPointeeLoc` if applicable. * For entries in `LocToVal` that correspond to declarations, print the names of the declarations next to them. I've removed the FIXME because all relevant fields are now being dumped. I'm not sure we actually need the capability for the caller to specify which fields to dump, so I've simply deleted this part of the comment. >From e65a6325a8d8f85a69926db51499656d62e1c032 Mon Sep 17 00:00:00 2001 From: Martin Braenne <mboe...@google.com> Date: Tue, 30 Jan 2024 11:18:51 +0000 Subject: [PATCH] [clang][dataflow] Extend debug output for `Environment`. * Print `ReturnLoc`, `ReturnVal`, and `ThisPointeeLoc` if applicable. * For entries in `LocToVal` that correspond to declarations, print the names of the declarations next to them. I've removed the FIXME because all relevant fields are now being dumped.
