From c75df6f96c59beed8632e3aced5fb4faabaa6c5b Mon Sep 17 00:00:00 2001 From: Michael Neuling Date: Mon, 25 Jun 2012 13:33:10 +0000 Subject: powerpc: Fix usage of register macros getting ready for %r0 change Anything that uses a constructed instruction (ie. from ppc-opcode.h), need to use the new R0 macro, as %r0 is not going to work. Also convert usages of macros where we are just determining an offset (usually for a load/store), like: std r14,STK_REG(r14)(r1) Can't use STK_REG(r14) as %r14 doesn't work in the STK_REG macro since it's just calculating an offset.
