From c152f3a44dca47acd7c1b4e32deee766ed615469 Mon Sep 17 00:00:00 2001 From: Glenn Washburn Date: Tue, 21 Feb 2023 12:28:48 -0600 Subject: [PATCH] gdb: If no modules have been loaded, do not try to load module symbols This prevents load_all_modules from failing when called before any modules have been loaded. Failures in GDB user-defined functions cause any function which called them to also fail.
