llvm dev - Feb 2021 - matchertable document

hi,
I want to understand how instruction is matched, but I could not find
any document about martchertable by googling.

Is there any document about how it is generated by tablegen and how it
works for instruction selection?

Thanks

Janboe

Hi Janboe,

As far as I know, there is no such document. The closest thing I have found 
which explains how the matchtable works is a blog post: 
https://eli.thegreenplace.net/2013/02/25/a-deeper-look-into-the-llvm-code-generator-part-1

It's dated, but the core of it is still applies today.

Cheers,
Gabriel
