Subject: [PATCH v2 15/17] target/arm: Move 'env' argument of recps_f32 and rsqrts_f32 helpers to usual place
Date: Tue, 12 May 2020 17:39:02 +0100 [thread overview]
Message-ID: <20200512163904.10918-16-peter.maydell@linaro.org> (raw)
In-Reply-To: <20200512163904.10918-1-peter.maydell@linaro.org>
The usual location for the env argument in the argument list of a TCG helper
is immediately after the return-value argument. recps_f32 and rsqrts_f32
differ in that they put it at the end.
Move the env argument to its usual place; this will allow us to
more easily use these helper functions with the gvec APIs.
