From 07931c5a08d4836e127b63762fe310982172e9fa Mon Sep 17 00:00:00 2001 From: David Wood Date: Wed, 23 Aug 2023 15:29:23 +0100 Subject: codegen_llvm: set DW_AT_accessibility Sets the accessibility of types and fields in DWARF using `DW_AT_accessibility` attribute. `DW_AT_accessibility` (public/protected/private) isn't exactly right for Rust, but neither is `DW_AT_visibility` (local/exported/qualified), and there's no way to set `DW_AT_visbility` in LLVM's API.
