From 61b2e136db5a628cadcb4a1a5c68efbab4c8e2fb Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Alex=20Benn=C3=A9e?= Date: Thu, 2 Mar 2023 18:57:58 -0800 Subject: [PATCH] gdbstub: only compile gdbstub twice for whole build MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Now we have removed any target specific bits from the core gdbstub code we only need to build it twice. We have to jump a few meson hoops to manually define the CONFIG_USER_ONLY symbol but it seems to work.
