Added opcode BUNDLE 2. Taught MachineInstr class to deal with bundled MIs 3. Changed MachineBasicBlock iterator to skip over bundled MIs; added an iterator to walk all the MIs 4. Taught MachineBasicBlock methods about bundled MIs git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145975 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/TailDuplication.cpp | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) (limited to 'lib/CodeGen/TailDuplication.cpp') diff --git a/lib/CodeGen/TailDuplication.cpp b/lib/CodeGen/TailDuplication.cpp index 3a6211a0f3..adfce863d0 100644 --- a/lib/CodeGen/TailDuplication.cpp +++ b/lib/CodeGen/TailDuplication.cpp @@ -561,8 +561,7 @@ TailDuplicatePass::shouldTailDuplicate(const MachineFunction &MF, // Check the instructions in the block to determine whether tail-duplication // is invalid or unlikely to be profitable. unsigned InstrCount = 0; - for (MachineBasicBlock::const_iterator I = TailBB.begin(); I != TailBB.end(); - ++I) { + for (MachineBasicBlock::iterator I = TailBB.begin(); I != TailBB.end(); ++I) { // Non-duplicable things shouldn't be tail-duplicated. if (I->getDesc().isNotDuplicable()) return false; -- cgit v1.2.3
