From: Jakob Stoklund Olesen Date: Wed, 9 Jan 2013 01:02:19 +0000 (+0000) Subject: Add a getBundleEnd() function to go with the existing getBundleStart(). X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=d700a2f9c54e3312d28c132663bf60f81662b7f7;p=oota-llvm.git Add a getBundleEnd() function to go with the existing getBundleStart(). This is easier implemented now that bundle flags are symmetric. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171927 91177308-0d34-0410-b5e6-96231b3b80d8 --- diff --git a/include/llvm/CodeGen/MachineInstrBuilder.h b/include/llvm/CodeGen/MachineInstrBuilder.h index a2d3d63bdbb..92c8da991ca 100644 --- a/include/llvm/CodeGen/MachineInstrBuilder.h +++ b/include/llvm/CodeGen/MachineInstrBuilder.h @@ -18,6 +18,7 @@ #define LLVM_CODEGEN_MACHINEINSTRBUILDER_H #include "llvm/CodeGen/MachineFunction.h" +#include "llvm/CodeGen/MachineInstrBundle.h" #include "llvm/Support/ErrorHandling.h" namespace llvm { @@ -391,11 +392,7 @@ public: /// Create an MIBundleBuilder representing an existing instruction or bundle /// that has MI as its head. explicit MIBundleBuilder(MachineInstr *MI) - : MBB(*MI->getParent()), Begin(MI) { - MachineBasicBlock::iterator I = MI; - ++I; - End = I.getInstrIterator(); - } + : MBB(*MI->getParent()), Begin(MI), End(getBundleEnd(MI)) {} /// Return a reference to the basic block containing this bundle.
