From 224f9fd4191feaf104965d8feb814f7303923a47 Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Wed, 30 Apr 2014 13:56:50 -0700 Subject: tcg-ppc: Merge cache-utils into the backend As a "utility", it only supported ppc, and in a way that other tcg backends provided directly in tcg-target.h. Removing this disparity is easier now that the two ppc backends are merged.
