From c6ae604573f9e9d7b7a15388bdba2d1dabecd131 Mon Sep 17 00:00:00 2001 From: Simon Marchi Date: Thu, 13 Apr 2023 16:18:34 -0400 Subject: [PATCH] gdb: add inferior_cloned observable The following patch makes the amdgpu port transfer a property from the original inferior to the new inferior when using the clone-inferior command. Add the inferior_cloned observable to help with this.
