From 5a96b3dad2f634c9081c8b2b6c2575441dc5a2bd Mon Sep 17 00:00:00 2001 From: Evan Cheng Date: Wed, 7 Dec 2011 07:15:52 +0000 Subject: Add bundle aware API for querying instruction properties and switch the code generator to it. For non-bundle instructions, these behave exactly the same as the MC layer API. For properties like mayLoad / mayStore, look into the bundle and if any of the bundled instructions has the property it would return true. For properties like isPredicable, only return true if *all* of the bundled instructions have the property. For properties like canFoldAsLoad, isCompare, conservatively return false for bundles. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146026 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/MachineSink.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'lib/CodeGen/MachineSink.cpp') diff --git a/lib/CodeGen/MachineSink.cpp b/lib/CodeGen/MachineSink.cpp index 29cfb49953..8a34237789 100644 --- a/lib/CodeGen/MachineSink.cpp +++ b/lib/CodeGen/MachineSink.cpp @@ -291,7 +291,7 @@ bool MachineSinking::isWorthBreakingCriticalEdge(MachineInstr *MI, if (!CEBCandidates.insert(std::make_pair(From, To))) return true; - if (!MI->isCopy() && !MI->getDesc().isAsCheapAsAMove()) + if (!MI->isCopy() && !MI->isAsCheapAsAMove()) return true; // MI is cheap, we probably don't want to break the critical edge for it. -- cgit v1.2.3-70-g09d2
