From 5456788db7982938db6600d6308fd2f449b40d5c Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Tue, 25 Mar 2014 08:32:04 -0700 Subject: [PATCH] tcg-ppc64: Fix TCG_TARGET_CALL_STACK_OFFSET The calling convention reserves space for the 8 register parameters on the stack, so using only 6*8=48 as the offset was wrong. We never saw this bug because we don't have any helpers with more than 5 parameters.
