From 761e3c10881b5f521b19b713cf8d16c72c47affb Mon Sep 17 00:00:00 2001 From: Matheus Branco Borella Date: Tue, 29 Aug 2023 17:15:24 +0100 Subject: gdbstub: fixes cases where wrong threads were reported to GDB on SIGINT MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This fix is implemented by having the vCont handler set the value of `gdbserver_state.c_cpu` if any threads are to be resumed. The specific CPU picked is arbitrarily from the ones to be resumed, but it should be okay, as all GDB cares about is that it is a resumed thread.
