From 41fc8a573ea61b2463606a0714a9e563494da329 Mon Sep 17 00:00:00 2001 From: Andreas Hansson Date: Fri, 19 Sep 2014 10:35:18 -0400 Subject: arch: Pass faults by const reference where possible This patch changes how faults are passed between methods in an attempt to copy as few reference-counting pointer instances as possible. This should avoid unecessary copies being created, contributing to the increment/decrement of the reference counters. --- src/cpu/inorder/resource.hh | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/cpu/inorder/resource.hh') diff --git a/src/cpu/inorder/resource.hh b/src/cpu/inorder/resource.hh index ef712d5c9..eaecc2824 100644 --- a/src/cpu/inorder/resource.hh +++ b/src/cpu/inorder/resource.hh @@ -104,7 +104,7 @@ class Resource { virtual void instGraduated(InstSeqNum seq_num, ThreadID tid) { } /** Post-processsing for Trap Generated from this instruction */ - virtual void trap(Fault fault, ThreadID tid, DynInstPtr inst) { } + virtual void trap(const Fault &fault, ThreadID tid, DynInstPtr inst) { } /** Request usage of this resource.
