From 7de8a7169e0e87c960d06c60570bc062416e681f Mon Sep 17 00:00:00 2001 From: Joakim Tjernlund Date: Mon, 23 Jul 2012 10:58:03 +0000 Subject: powerpc: Stack Pointer not properly aligned The code first aligns the SP to 16 then subtract 8, making it 8 bytes aligned. Furthermore the initial stack frame not quite correct either.
