From 3a2c48cfc97f9046abbd810f1efb1aa824bcfaf1 Mon Sep 17 00:00:00 2001 From: Anton Blanchard Date: Sat, 10 Jun 2006 20:18:39 +1000 Subject: [POWERPC] 64bit FPSCR support Forthcoming machines will extend the FPSCR to 64 bits. We already had a 64-bit save area for the FPSCR, but we need to use a new form of the mtfsf instruction. Fortunately this new form is decoded as an ordinary mtfsf by existing 64-bit processors.
