Subject: [Qemu-devel] [PATCH] Use float_relation_* constants
Date: Sat, 13 Dec 2008 17:31:26 -0800 [thread overview]
Message-ID: <20081214013126.GC23471@codesourcery.com> (raw)
(Apologies if this patch comes through multiple times; I've tried twice
already and haven't seen it come through on my end or in the list
archives.)
Use float_relation_* constants rather than magic numbers in
softfloat-native comparison routines.
