From 33b06b513e804ae64ebd5105fb703ec90bd7e173 Mon Sep 17 00:00:00 2001 From: Atsushi Nemoto Date: Mon, 18 Dec 2006 00:38:21 +0900 Subject: [PATCH] [MIPS] TX49: Fix use of CDEX build_store_reg() The commit a923660d786a53e78834b19062f7af2535f7f8ad accidently prevents TX49 from using CDEX. Use build_dst_pref() only if prefetch for store was really available.
