From 1f35b178858c693261b08ab41022f92e250e08b4 Mon Sep 17 00:00:00 2001 From: Devang Patel Date: Thu, 4 Aug 2011 20:02:18 +0000 Subject: [PATCH] We need to map DebugLoc. It leads to Fuction * (through subprogram entry node) which should be appropriately mapped. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136910 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Transforms/Utils/ValueMapper.cpp | 5 ++--- test/Linker/2011-08-04-DebugLoc.ll | 26 ++++++++++++++++++++++++++ test/Linker/2011-08-04-DebugLoc2.ll | 23 +++++++++++++++++++++++ 3 files changed, 51 insertions(+), 3 deletions(-) create mode 100644 test/Linker/2011-08-04-DebugLoc.ll create mode 100644 test/Linker/2011-08-04-DebugLoc2.ll diff --git a/lib/Transforms/Utils/ValueMapper.cpp b/lib/Transforms/Utils/ValueMapper.cpp index 973b105a1cb..fc2538db648 100644 --- a/lib/Transforms/Utils/ValueMapper.cpp +++ b/lib/Transforms/Utils/ValueMapper.cpp @@ -183,10 +183,9 @@ void llvm::RemapInstruction(Instruction *I, ValueToValueMapTy &VMap, } } - // Remap attached metadata.
