From 870ab98bee4312caf0ced42999e295f741aba853 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Mon, 22 Aug 2022 15:12:29 +0100 Subject: [PATCH] target/xtensa: Honour -semihosting-config userspace=on MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Honour the commandline -semihosting-config userspace=on option, instead of always permitting userspace semihosting calls in system emulation mode, by passing the correct value to the is_userspace argument of semihosting_enabled(). Note that this is a behaviour change: if the user wants to do semihosting calls from userspace they must now specifically enable them on the command line. xtensa semihosting is not implemented for linux-user builds.
