From fb31da1306e414e4101b84c89c3a6553efa48aff Mon Sep 17 00:00:00 2001 From: Adrian Prantl Date: Mon, 22 May 2017 20:47:09 +0000 Subject: Don't generate line&scope debug info for meta-instructions. MachineInstructions that don't generate any code (such as IMPLICIT_DEFs) should not generate any debug info either. Fixes PR33107. https://bugs.llvm.org/show_bug.cgi?id=33107 This reapplies r303566 without any modifications. The stage2 build failures persisted even after reverting this patch, and looking back through history, it looks like these tests are flaky. llvm-svn: 303575 --- llvm/lib/CodeGen/AsmPrinter/DebugHandlerBase.cpp | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'llvm/lib/CodeGen/AsmPrinter/DebugHandlerBase.cpp') diff --git a/llvm/lib/CodeGen/AsmPrinter/DebugHandlerBase.cpp b/llvm/lib/CodeGen/AsmPrinter/DebugHandlerBase.cpp index 826162ad47c..27ae77b18cd 100644 --- a/llvm/lib/CodeGen/AsmPrinter/DebugHandlerBase.cpp +++ b/llvm/lib/CodeGen/AsmPrinter/DebugHandlerBase.cpp @@ -223,9 +223,9 @@ void DebugHandlerBase::endInstruction() { return; assert(CurMI != nullptr); - // Don't create a new label after DBG_VALUE instructions. - // They don't generate code. - if (!CurMI->isDebugValue()) { + // Don't create a new label after DBG_VALUE and other instructions that don't + // generate code. + if (!CurMI->isMetaInstruction()) { PrevLabel = nullptr; PrevInstBB = CurMI->getParent(); } -- cgit v1.2.3
