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/MachineRegisterInfo.cpp | 9 +-------- 1 file changed, 1 insertion(+), 8 deletions(-) (limited to 'lib/CodeGen/MachineRegisterInfo.cpp') diff --git a/lib/CodeGen/MachineRegisterInfo.cpp b/lib/CodeGen/MachineRegisterInfo.cpp index b3fb33736f..7244d5f03a 100644 --- a/lib/CodeGen/MachineRegisterInfo.cpp +++ b/lib/CodeGen/MachineRegisterInfo.cpp @@ -210,15 +210,8 @@ MachineRegisterInfo::EmitLiveInCopies(MachineBasicBlock *EntryMBB, LiveIns.erase(LiveIns.begin() + i); --i; --e; } else { - DebugLoc DL; - // If there is a location for this live in then use it. - DenseMap::iterator DLI = - LiveInLocs.find(LiveIns[i].second); - if (DLI != LiveInLocs.end()) - DL = DLI->second; - // Emit a copy. - BuildMI(*EntryMBB, EntryMBB->begin(), DL, + BuildMI(*EntryMBB, EntryMBB->begin(), DebugLoc(), TII.get(TargetOpcode::COPY), LiveIns[i].second) .addReg(LiveIns[i].first); -- cgit v1.2.3-18-g5258
