Subject: [Qemu-devel] [PATCH 07/34] target-ppc: use the softfloat min/max functions
Date: Thu,  4 Oct 2012 15:56:29 +0200	[thread overview]
Message-ID: <1349359016-13107-8-git-send-email-agraf@suse.de> (raw)
In-Reply-To: <1349359016-13107-1-git-send-email-agraf@suse.de>

From: Aurelien Jarno <aurelien@aurel32.net>

Use the new softfloat float32_min() and float32_max() to implement the
vminfp and vmaxfp instructions. As a bonus we can get rid of the call to
the HANDLE_NAN2 macro, as the NaN handling is directly done at the
softfloat level.
