From fbdc200ac2d0d29e88ee6af9b77810c0f84265a6 Mon Sep 17 00:00:00 2001 From: Tom Musta Date: Mon, 30 Jun 2014 08:13:36 -0500 Subject: linux-user: Fix Stack Pointer Bug in PPC setup_rt_frame The code that sets the stack frame back pointer is incorrect for the setup_rt_frame() code; qemu will abort (SIGSEGV) in some environments. The setup_frame code was fixed in commit beb526b12134a6b6744125deec5a7fe24a8f92e3 but the setup_rt_frame code was not. Make the setup_rt_frame code consistent with the setup_frame code.
