From d742533dbc43f54798becb48ed7d3a2d97cf8150 Mon Sep 17 00:00:00 2001 From: Jakob Stoklund Olesen Date: Tue, 18 Dec 2012 23:21:49 +0000 Subject: Use bidirectional bundle flags to simplify important functions. The bundle_iterator::operator++ function now doesn't need to dig out the basic block and check against end(). It can use the isBundledWithSucc() flag to find the last bundled instruction safely. Similarly, MachineInstr::isBundled() no longer needs to look at iterators etc. It only has to look at flags. llvm-svn: 170473 --- llvm/lib/CodeGen/MachineInstr.cpp | 10 ---------- 1 file changed, 10 deletions(-) (limited to 'llvm/lib/CodeGen/MachineInstr.cpp') diff --git a/llvm/lib/CodeGen/MachineInstr.cpp b/llvm/lib/CodeGen/MachineInstr.cpp index 3b83d02bb09..ce77d61460b 100644 --- a/llvm/lib/CodeGen/MachineInstr.cpp +++ b/llvm/lib/CodeGen/MachineInstr.cpp @@ -909,16 +909,6 @@ void MachineInstr::unbundleFromSucc() { Succ->clearFlag(BundledPred); } -/// isBundled - Return true if this instruction part of a bundle.
