Subject: [PULL 09/11] target/nios2: Honour -semihosting-config userspace=on
Date: Wed, 14 Sep 2022 14:23:06 +0100 [thread overview]
Message-ID: <20220914132308.118495-10-richard.henderson@linaro.org> (raw)
In-Reply-To: <20220914132308.118495-1-richard.henderson@linaro.org>
From: Peter Maydell <peter.maydell@linaro.org>
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.
nios2 semihosting is not implemented for linux-user builds.
