[Qemu-devel] [PATCH V2] softfloat: Rename float*_is_nan() functions to f

From: Peter Maydell
Subject: [Qemu-devel] [PATCH V2] softfloat: Rename float*_is_nan() functions to float*_is_quiet_nan()
Date: Fri, 17 Dec 2010 15:56:06 +0000 
The softfloat functions float*_is_nan() were badly misnamed,
because they return true only for quiet NaNs, not for all NaNs.
Rename them to float*_is_quiet_nan() to more accurately reflect
what they do.

This change was produced by:
 perl -p -i -e 's/_is_nan/_is_quiet_nan/g' $(git grep -l is_nan)
(with the results manually checked.)

This is just a refresh of the first patch against current master;
the only difference is that the addition of float32_maybe_silence_nan()
meant that the context for the hunk in softfloat.h changing the
prototypes is slightly different. I've therefore retained the
reviewed-by/acked-by lines from the first time around.

Can this patch be applied? (There are more ARM/softfloat patches
in my queue which will break it again otherwise...)
