Subject: [PATCH 2/3] powerpc e500: set -mfloat-gprs=double
Date: Tue, 27 Mar 2012 14:51:08 -0500 [thread overview]
Message-ID: <1332877869-12195-2-git-send-email-kergoth@gmail.com> (raw)
In-Reply-To: <1332877869-12195-1-git-send-email-kergoth@gmail.com>
From: Christopher Larson <chris_larson@mentor.com>
Use of FPRs instead of GPRs is incompatible with e500/SPE, so let's be
explicit about the use of GPRs to avoid potential errors. For example, with
the Sourcery G++ toolchain, one can hit: conftest.c:1:0: error: E500 and FPRs
not supported.
