From: Wesley Peck Date: Wed, 24 Feb 2010 20:16:27 +0000 (+0000) Subject: Adding function "lookupGCCName" to MBlazeIntrinsicInfo X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=173c5c40f6cda11fa7f10a3ecf93c204f85a9495;p=oota-llvm.git Adding function "lookupGCCName" to MBlazeIntrinsicInfo Adding the function "lookupGCCName" to the MBlazeIntrinsicInfo class to support the Clang MicroBlaze target. Additionally, minor fixes which remove some unused PIC code (PIC is not supported yet in the MicroBlaze backend) and removed some unused variables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97054 91177308-0d34-0410-b5e6-96231b3b80d8 --- diff --git a/lib/Target/MBlaze/MBlazeISelLowering.cpp b/lib/Target/MBlaze/MBlazeISelLowering.cpp index 0acbe3fec6e..7790248669f 100644 --- a/lib/Target/MBlaze/MBlazeISelLowering.cpp +++ b/lib/Target/MBlaze/MBlazeISelLowering.cpp @@ -470,7 +470,6 @@ LowerCall(SDValue Chain, SDValue Callee, CallingConv::ID CallConv, SmallVectorImpl &InVals) { MachineFunction &MF = DAG.getMachineFunction(); MachineFrameInfo *MFI = MF.getFrameInfo(); - bool IsPIC = getTargetMachine().getRelocationModel() == Reloc::PIC_; // Analyze operands of the call, assigning locations to each operand.
