From d0aa0cdbc6fee00f2b2019633a9b9d00d301ac68 Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Mon, 28 Oct 2002 05:30:46 +0000 Subject: Change MachineBasicBlock's to not be Annotations, instead they are kept as part of a linked list tracked by MachineFunction. MachineBasicBlock::get is now linear time instead of constant time, and thus is deprecated! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4337 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/MachineFunction.cpp | 15 +++++++++++++++ 1 file changed, 15 insertions(+) (limited to 'lib/CodeGen/MachineFunction.cpp') diff --git a/lib/CodeGen/MachineFunction.cpp b/lib/CodeGen/MachineFunction.cpp index b9c017a459..15036a4d07 100644 --- a/lib/CodeGen/MachineFunction.cpp +++ b/lib/CodeGen/MachineFunction.cpp @@ -72,6 +72,21 @@ Pass *createMachineCodeDestructionPass() { } +// get - This deprecated static method returns the MachineBasicBlock object +// for the specified BasicBlock. +// +MachineBasicBlock& MachineBasicBlock::get(const BasicBlock *BB) { + const Function *F = BB->getParent(); + MachineFunction &MF = MachineFunction::get(F); + + for (MachineFunction::iterator I = MF.begin(), E = MF.end(); I != E; ++I) + if (I->getBasicBlock() == BB) + return *I; + assert(0 && "MachineBasicBlock object not found for specified block!"); + return get(BB); +} + + //===---------------------------------------------------------------------===// // MachineFunction implementation //===---------------------------------------------------------------------===// -- cgit v1.2.3-18-g5258
