From a3437647dc6996499db4823c31242184c93e6e2e Mon Sep 17 00:00:00 2001 From: Argyrios Kyrtzidis Date: Wed, 20 May 2009 22:57:17 +0000 Subject: Introduce DebugScope which gets embedded into the machine instructions' DebugLoc. DebugScope refers to a debug region, function or block. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72191 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/MachineFunction.cpp | 18 +++++++++++++++++- 1 file changed, 17 insertions(+), 1 deletion(-) (limited to 'lib/CodeGen/MachineFunction.cpp') diff --git a/lib/CodeGen/MachineFunction.cpp b/lib/CodeGen/MachineFunction.cpp index cacfed1d9f..d1d782c825 100644 --- a/lib/CodeGen/MachineFunction.cpp +++ b/lib/CodeGen/MachineFunction.cpp @@ -403,8 +403,9 @@ unsigned MachineFunction::addLiveIn(unsigned PReg, /// source file, line, and column.
