[llvm-dev] [NPM] Register target specific pass with opt

[Chen, Yuanfang via llvm-dev]

 Hi Ankit,

Testing target specific passes using opt+NPM is not currently supported. The work is still work-in-progress. What is the motivation for doing this?

Subject: [llvm-dev] [NPM] Register target specific pass with opt

Hello LLVM community,

I was trying to port a target specific loop transformation pass (HexagonVectorLoopCarriedReusePass) to the New Pass Manager. However, I could not figure out a way to register this pass with opt. I can see that llvm/lib/Passes/PassRegistry.def is the registry for target independent passes. Can anyone point me to an example/API which can help me in registering this pass so that I can use it -passes option in opt?

Thanks
Ankit
