Dear Andrew and the Group,

I’m trying come up with a SchedMachineModel for the AMD bulldozer  [http://en.wikipedia.org/wiki/Bulldozer_(microarchitecture)](http://en.wikipedia.org/wiki/Bulldozer_(microarchitecture)).

The model is not exist for the same .Please correct me if am i wrong here.

I was going through your reference @ https://llvm.org/svn/llvm-project/llvm/trunk/include/llvm/Target/TargetSchedule.td .

But I couldn’t model some of the your definitions in the reference like

a)Subtargets

b)SchedReadWrite and SchedReadAdvance

c) per-operand

to the processor architecture instance .

I will be glad if you give me some instance example on the above definitions

Thanks in Advance

Hi Umesh,

You should send patches to llvm-commits@cs.uiuc.edu, also each patch
should be its own plain-text attachment.
