From d9df5017040489303acb57bdd8697ef0f8bafc08 Mon Sep 17 00:00:00 2001 From: Bob Wilson Date: Thu, 9 Apr 2009 17:16:43 +0000 Subject: Fix pr3954. The register scavenger asserts for inline assembly with register destinations that are tied to source operands. The TargetInstrDescr::findTiedToSrcOperand method silently fails for inline assembly. The existing MachineInstr::isRegReDefinedByTwoAddr was very close to doing what is needed, so this revision makes a few changes to that method and also renames it to isRegTiedToUseOperand (for consistency with the very similar isRegTiedToDefOperand and because it handles both two-address instructions and inline assembly with tied registers). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68714 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/LiveIntervalAnalysis.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'lib/CodeGen/LiveIntervalAnalysis.cpp') diff --git a/lib/CodeGen/LiveIntervalAnalysis.cpp b/lib/CodeGen/LiveIntervalAnalysis.cpp index cb08fe759f..3bc05a9b9a 100644 --- a/lib/CodeGen/LiveIntervalAnalysis.cpp +++ b/lib/CodeGen/LiveIntervalAnalysis.cpp @@ -469,7 +469,7 @@ void LiveIntervals::handleVirtualRegisterDef(MachineBasicBlock *mbb, // must be due to phi elimination or two addr elimination.
