From 00e6fd3e03b8df5553c6ea02bd95630549b0e2d1 Mon Sep 17 00:00:00 2001 From: Tom Musta Date: Wed, 12 Nov 2014 15:46:02 -0600 Subject: [PATCH] target-ppc: Fully Migrate to gen_set_cr1_from_fpscr Eliminate the set_rc argument from the gen_compute_fprf utility and the corresponding (and incorrect) implementation. Replace it with calls to the gen_set_cr1_from_fpscr() utility.
