From d9d07780ff0d393a34cbd57cd2b85bdd8c947a04 Mon Sep 17 00:00:00 2001 From: Matthijs Kooijman Date: Mon, 13 Oct 2008 12:41:46 +0000 Subject: [PATCH] * Make TargetLowering not crash when TargetMachine::getTargetAsmInfo() returns null. This assumes that any target that does not have AsmInfo, does not support "LocAndDot". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57438 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/SelectionDAG/TargetLowering.cpp | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/lib/CodeGen/SelectionDAG/TargetLowering.cpp b/lib/CodeGen/SelectionDAG/TargetLowering.cpp index 7e17daaa0f6..05edb6348d6 100644 --- a/lib/CodeGen/SelectionDAG/TargetLowering.cpp +++ b/lib/CodeGen/SelectionDAG/TargetLowering.cpp @@ -473,7 +473,8 @@ TargetLowering::TargetLowering(TargetMachine &tm) InitCmpLibcallCCs(CmpLibcallCCs); // Tell Legalize whether the assembler supports DEBUG_LOC. - if (!TM.getTargetAsmInfo()->hasDotLocAndDotFile()) + const TargetAsmInfo *TASM = TM.getTargetAsmInfo(); + if (!TASM || !TASM->hasDotLocAndDotFile()) setOperationAction(ISD::DEBUG_LOC, MVT::Other, Expand); }
