[OpenRISC] Instruction scheduler for llvm-or1k

[Ziqiang Patrick Huang]

Hi,

I'm looking at the source code of the port of LLVM for the OpenRISC 1000
architecture under
https://github.com/openrisc/llvm-or1k/tree/master/lib/Target/OR1K

It seems like right now this implementation does not have an instruction
scheduler which reorders instructions after instruction selection stage.

I'm wondering if anyone has come up with an instruction scheduler or is
working on that ?
Any suggestion is appreciated.

Thanks,
Ziqiang
