From: Bill Wendling Date: Tue, 3 Feb 2009 00:55:04 +0000 (+0000) Subject: Create DebugLoc information in FastISel. Several temporary methods were X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=9bc96a57206cbebaa9b0ba9979f949eb10c1592c;p=oota-llvm.git Create DebugLoc information in FastISel. Several temporary methods were created. Specifically, those BuildMIs which use "DebugLoc::getUnknownLoc()". I'll remove them soon. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63584 91177308-0d34-0410-b5e6-96231b3b80d8 --- diff --git a/include/llvm/CodeGen/FastISel.h b/include/llvm/CodeGen/FastISel.h index 8c048480694..1c26b3fd763 100644 --- a/include/llvm/CodeGen/FastISel.h +++ b/include/llvm/CodeGen/FastISel.h @@ -16,6 +16,7 @@ #include "llvm/ADT/DenseMap.h" #include "llvm/ADT/SmallSet.h" +#include "llvm/CodeGen/DebugLoc.h" #include "llvm/CodeGen/SelectionDAGNodes.h" namespace llvm { @@ -55,28 +56,33 @@ protected: MachineRegisterInfo &MRI; MachineFrameInfo &MFI; MachineConstantPool &MCP; + DebugLoc DL; const TargetMachine &TM; const TargetData &TD; const TargetInstrInfo &TII; const TargetLowering &TLI; public: - /// startNewBlock - Set the current block, to which generated - /// machine instructions will be appended, and clear the local - /// CSE map. + /// startNewBlock - Set the current block to which generated machine + /// instructions will be appended, and clear the local CSE map. /// void startNewBlock(MachineBasicBlock *mbb) { setCurrentBlock(mbb); LocalValueMap.clear(); } - /// setCurrentBlock - Set the current block, to which generated - /// machine instructions will be appended. + /// setCurrentBlock - Set the current block to which generated machine + /// instructions will be appended. /// void setCurrentBlock(MachineBasicBlock *mbb) { MBB = mbb; } + /// setCurDebugLoc - Set the current debug location information, which is used + /// when creating a machine instruction. + /// + void setCurDebugLoc(DebugLoc dl) { DL = dl; } + /// SelectInstruction - Do "fast" instruction selection for the given /// LLVM IR instruction, and append generated machine instructions to /// the current block.
