From 80da865f77a57c0dd923d6cea8a9619368e4e91b Mon Sep 17 00:00:00 2001 From: Alkis Evlogimenos Date: Thu, 12 Feb 2004 02:27:10 +0000 Subject: Change MachineBasicBlock's vector of MachineInstr pointers into an ilist of MachineInstr objects. This allows constant time removal and insertion of MachineInstr instances from anywhere in each MachineBasicBlock. It also allows for constant time splicing of MachineInstrs into or out of MachineBasicBlocks. llvm-svn: 11340 --- llvm/lib/CodeGen/MachineFunction.cpp | 30 +----------------------------- 1 file changed, 1 insertion(+), 29 deletions(-) (limited to 'llvm/lib/CodeGen/MachineFunction.cpp') diff --git a/llvm/lib/CodeGen/MachineFunction.cpp b/llvm/lib/CodeGen/MachineFunction.cpp index 6c15ad5c4d9..4de55f4596e 100644 --- a/llvm/lib/CodeGen/MachineFunction.cpp +++ b/llvm/lib/CodeGen/MachineFunction.cpp @@ -62,34 +62,6 @@ FunctionPass *llvm::createMachineFunctionPrinterPass(std::ostream *OS, return new Printer(OS, Banner); } -namespace { - struct Deleter : public MachineFunctionPass { - const char *getPassName() const { return "Machine Code Deleter"; } - - bool runOnMachineFunction(MachineFunction &MF) { - // Delete all of the MachineInstrs out of the function.
