Is there some road map about torch_glow's JIT developing?

[edimetia3d]

Hi,

I am trying to implement a cusomt torchscript jit backend, and have got some info at pytorch forum. https://discuss.pytorch.org/t/is-there-some-document-about-adding-a-custom-jit-backend/128247/2

Follwing advice there, I am trying to implement a jit compiler by adding a "custom post pass", like torch_glow did, and I think this solution is good enough for me now.

However, I noticed that torch_glow marked the pass as enableFusionPass_DO_NOT_USE_THIS, and implement a new torch::jit::backend<TorchGlowBackend>("glow").

After some googling, I havn't found any information about this, so I came here to try to find some help.

1. Why torch_glow mark the enableFusionPass_DO_NOT_USE_THIS.
2. When should I implement a torch::jit::backend? Is there some roadmap about the jit backend?

Sincerely
