[llvm-dev] matchertable document

[Gabriel Hjort Åkerlund via llvm-dev]

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

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
