From 68e6beeccc0b9ac2e8d3687a8a5b7d4b172edca1 Mon Sep 17 00:00:00 2001 From: Devang Patel Date: Mon, 21 Feb 2011 23:21:26 +0000 Subject: Revert r124611 - "Keep track of incoming argument's location while emitting LiveIns." In other words, do not keep track of argument's location. The debugger (gdb) is not prepared to see line table entries for arguments. For the debugger, "second" line table entry marks beginning of function body. This requires some coordination with debugger to get this working. - The debugger needs to be aware of prolog_end attribute attached with line table entries. - The compiler needs to accurately mark prolog_end in line table entries (at -O0 and at -O1+) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126155 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/MachineFunction.cpp | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-) (limited to 'lib/CodeGen/MachineFunction.cpp') diff --git a/lib/CodeGen/MachineFunction.cpp b/lib/CodeGen/MachineFunction.cpp index 85532407ca..962362761f 100644 --- a/lib/CodeGen/MachineFunction.cpp +++ b/lib/CodeGen/MachineFunction.cpp @@ -396,8 +396,7 @@ void MachineFunction::viewCFGOnly() const /// addLiveIn - Add the specified physical register as a live-in value and /// create a corresponding virtual register for it. unsigned MachineFunction::addLiveIn(unsigned PReg, - const TargetRegisterClass *RC, - DebugLoc DL) { + const TargetRegisterClass *RC) { MachineRegisterInfo &MRI = getRegInfo(); unsigned VReg = MRI.getLiveInVirtReg(PReg); if (VReg) { @@ -406,7 +405,6 @@ unsigned MachineFunction::addLiveIn(unsigned PReg, } VReg = MRI.createVirtualRegister(RC); MRI.addLiveIn(PReg, VReg); - MRI.addLiveInLoc(VReg, DL); return VReg; } -- cgit v1.2.3-18-g5258
