Subject: [Qemu-devel] [PATCH 04/14] target-ppc: Replace isden by float64_is_zero_or_denormal
Date: Thu,  5 Jan 2017 16:56:09 +0530	[thread overview]
Message-ID: <1483615579-17618-5-git-send-email-nikunj@linux.vnet.ibm.com> (raw)
In-Reply-To: <1483615579-17618-1-git-send-email-nikunj@linux.vnet.ibm.com>

From: Bharata B Rao <bharata@linux.vnet.ibm.com>

Replace isden() by float64_is_zero_or_denormal() so that code in
helper_compute_fprf() can be reused to work with float128 argument.
