From 65547233e04b32e087f74f8f5e9d3ffb6fe2c198 Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Thu, 13 Jul 2017 15:03:27 -0600 Subject: [PATCH] Make gdb.lookup_typename work for Rust types PR rust/21763 points out that gdb.lookup_typename does not work properly for (some) Rust types. I tracked this down to a missing case in symbol_matches_domain.
