[Qemu-ppc] [PATCH v1 05/14] target-ppc: Rename helper_compute_fprf to he


From: Nikunj A Dadhania
Subject: [Qemu-ppc] [PATCH v1 05/14] target-ppc: Rename helper_compute_fprf to helper_compute_fprf_float64
Date: Fri, 6 Jan 2017 11:44:47 +0530

From: Bharata B Rao <address@hidden>

Since helper_compute_fprf() works on float64 argument, rename it
to helper_compute_fprf_float64(). Also use a macro to generate
helper_compute_fprf_float64() so that float128 version of the same
helper can be introduced easily later.
