From 548c96095dae2af37c4145ff11f0d010c43e2be2 Mon Sep 17 00:00:00 2001 From: Alex Bennée Date: Thu, 2 Mar 2023 18:57:43 -0800 Subject: includes: move tb_flush into its own header MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This aids subsystems (like gdbstub) that want to trigger a flush without pulling target specific headers.
