From f15758b1d3b81f90a8c2b18c0487056d049d9bd9 Mon Sep 17 00:00:00 2001 From: Hal Finkel Date: Thu, 12 Dec 2013 00:19:07 +0000 Subject: [PATCH] Add isBarrier to SDep SDep had is* functions for the other kinds of order dependencies (isMustAlias, isWeak, isArtificial, etc.), but not for barrier. Upcoming commits in the PowerPC backend will make use of this function. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@197098 91177308-0d34-0410-b5e6-96231b3b80d8 --- include/llvm/CodeGen/ScheduleDAG.h | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/include/llvm/CodeGen/ScheduleDAG.h b/include/llvm/CodeGen/ScheduleDAG.h index 66bf8c5dd77..c49a9a7f569 100644 --- a/include/llvm/CodeGen/ScheduleDAG.h +++ b/include/llvm/CodeGen/ScheduleDAG.h @@ -184,6 +184,12 @@ namespace llvm { || Contents.OrdKind == MustAliasMem); } + /// isBarrier - Test if this is an Order dependence that is marked + /// as a barrier. + bool isBarrier() const { + return getKind() == Order && Contents.OrdKind == Barrier; + } + /// isMustAlias - Test if this is an Order dependence that is marked /// as "must alias", meaning that the SUnits at either end of the edge /// have a memory dependence on a known memory location. -- 2.34.1
