From 5cd496e72773985590a7dfc003279459951c81d7 Mon Sep 17 00:00:00 2001 From: Jim Laskey Date: Sat, 4 Nov 2006 10:48:07 +0000 Subject: [PATCH] Live local variables are being dropped because the begin or end labels marking their scope are being deleted. Workaround is to widen scope to full function. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31454 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/DwarfWriter.cpp | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) diff --git a/lib/CodeGen/DwarfWriter.cpp b/lib/CodeGen/DwarfWriter.cpp index 40518eb2093..1c33cd85f1e 100644 --- a/lib/CodeGen/DwarfWriter.cpp +++ b/lib/CodeGen/DwarfWriter.cpp @@ -1862,9 +1862,10 @@ private: unsigned StartID = Scope->getStartLabelID(); unsigned EndID = Scope->getEndLabelID(); - // Throw out scope if block is discarded. - if (StartID && !DebugInfo->isLabelValid(StartID)) continue; - if (EndID && !DebugInfo->isLabelValid(EndID)) continue; + // Widen scope if label is discarded. + // FIXME - really need to find a GOOD label if a block is dead. + if (StartID && !DebugInfo->isLabelValid(StartID)) StartID = 0; + if (EndID && !DebugInfo->isLabelValid(EndID)) EndID = 0; DIE *ScopeDie = new DIE(DW_TAG_lexical_block); -- 2.34.1
