From 472b24ce2b4f22363ec9a556e479be6ad5180727 Mon Sep 17 00:00:00 2001 From: Tom Musta Date: Tue, 22 Oct 2013 22:07:41 +1100 Subject: Add VSR to Global Registers This patch adds VSX VSRs to the the list of global register indices. More specifically, it adds the lower halves of the first 32 VSRs to the list of global register indices. The upper halves of the first 32 VSRs are already defined via cpu_fpr[]. And the second 32 VSRs are already defined via the cpu_avrh[] and cpu_avrl[] arrays.
