Does anyone know how to parse LLVM instruction tables?

[Inori]

I had tried to convert GCN instruction tables in LLVM project to GPCS4's instruction table month ago,
but failed because that it really really complicated....Orz...
Currently I have to fix the table as development goes, which is to say, once I meet a new instruction,
I go to the table then fill the fields correspond to the instruction..
This is really annoying and waste a lot of time.
I believe the GCN table in llvm project is the most detailed and accurate which could be found on the internet.
If the conversion could be done, it would be really nice.
