From 6bbad7a91efe49b080391a45bc6305449050465a Mon Sep 17 00:00:00 2001 From: Tom Musta Date: Mon, 31 Mar 2014 16:04:01 -0500 Subject: [PATCH] target-ppc: Correct VSX FP to FP Conversions This change corrects the VSX double precision to single precision and single precision to double precisions conversion routines. The endian correct accessors are now used. The auxiliary "j" index is no longer necessary and is eliminated.
