From f44c99607a46484c52f03aed373e3a3a194af721 Mon Sep 17 00:00:00 2001 From: Blue Swirl Date: Sat, 14 May 2011 17:06:56 +0000 Subject: TCG/Sparc64: use stack for TCG temps Use stack instead of temp_buf array in CPUState for TCG temps. On Sparc64, stack pointer is not aligned but there is a fixed bias of 2047, so don't try to enforce alignment.
