Subject: [PULL 04/28] target/alpha: Handle SWCR_MAP_DMZ earlier
Date: Thu, 26 Sep 2019 19:35:29 +0100 [thread overview]
Message-ID: <20190926183553.13895-5-alex.bennee@linaro.org> (raw)
In-Reply-To: <20190926183553.13895-1-alex.bennee@linaro.org>
From: Richard Henderson <richard.henderson@linaro.org>
Since we're converting the swcr to fpcr format for exceptions,
it's trivial to add FPCR_DNZ to the set of fpcr bits overriden.
No functional change.
