Subject: [PATCH 0/7] target/alpha: Fix linux-user exception for CVTTQ
Date: Fri, 20 Sep 2019 21:32:49 -0700 [thread overview]
Message-ID: <20190921043256.4575-1-richard.henderson@linaro.org> (raw)
Alex's new float_convs test dies with SIGFPE for alpha-linux-user.
This is fixed in patch 6, where I mask the exception similar to how
the kernel would, when passed through the software completion handler.
Patches 2 & 3 fix bugs that I noticed in the process; the rest are
simple cleanup, trying to make the code better or easier.
