From fa3872e7ad06f2959f61eba4f0a5c91be7133091 Mon Sep 17 00:00:00 2001 From: Matthias Braun Date: Mon, 18 May 2015 20:27:55 +0000 Subject: MachineInstr: Change return value of getOpcode() to unsigned. This was previously returning int. However there are no negative opcode numbers and more importantly this was needlessly different from MCInstrDesc::getOpcode() (which even is the value returned here) and SDValue::getOpcode()/SDNode::getOpcode(). llvm-svn: 237611 --- llvm/lib/CodeGen/PrologEpilogInserter.cpp | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) (limited to 'llvm/lib/CodeGen/PrologEpilogInserter.cpp') diff --git a/llvm/lib/CodeGen/PrologEpilogInserter.cpp b/llvm/lib/CodeGen/PrologEpilogInserter.cpp index e4f359c213c..76583f0de88 100644 --- a/llvm/lib/CodeGen/PrologEpilogInserter.cpp +++ b/llvm/lib/CodeGen/PrologEpilogInserter.cpp @@ -248,12 +248,12 @@ void PEI::calculateCallsInformation(MachineFunction &Fn) { bool AdjustsStack = MFI->adjustsStack(); // Get the function call frame set-up and tear-down instruction opcode - int FrameSetupOpcode = TII.getCallFrameSetupOpcode(); - int FrameDestroyOpcode = TII.getCallFrameDestroyOpcode(); + unsigned FrameSetupOpcode = TII.getCallFrameSetupOpcode(); + unsigned FrameDestroyOpcode = TII.getCallFrameDestroyOpcode(); // Early exit for targets which have no call frame setup/destroy pseudo // instructions. - if (FrameSetupOpcode == -1 && FrameDestroyOpcode == -1) + if (FrameSetupOpcode == ~0u && FrameDestroyOpcode == ~0u) return; std::vector FrameSDOps; @@ -864,8 +864,8 @@ void PEI::replaceFrameIndices(MachineBasicBlock *BB, MachineFunction &Fn, const TargetInstrInfo &TII = *Fn.getSubtarget().getInstrInfo(); const TargetRegisterInfo &TRI = *Fn.getSubtarget().getRegisterInfo(); const TargetFrameLowering *TFI = Fn.getSubtarget().getFrameLowering(); - int FrameSetupOpcode = TII.getCallFrameSetupOpcode(); - int FrameDestroyOpcode = TII.getCallFrameDestroyOpcode(); + unsigned FrameSetupOpcode = TII.getCallFrameSetupOpcode(); + unsigned FrameDestroyOpcode = TII.getCallFrameDestroyOpcode(); if (RS && !FrameIndexVirtualScavenging) RS->enterBasicBlock(BB); -- cgit v1.2.3
