From 270dbee10cd31b86f0a3a8a2691026bdb0b9a071 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Philippe=20Mathieu-Daud=C3=A9?= Date: Thu, 23 Jan 2025 14:09:19 +0100 Subject: [PATCH] gdbstub: Check for TCG before calling tb_flush() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Use the tcg_enabled() check so the compiler can elide the call when TCG isn't available, allowing to remove the tb_flush() stub.
