<div dir="ltr">Thanks all. The documentation for TableGen in <a href="http://LLVM.ORG">LLVM.ORG</a> gives a detailed introduction of TableGen Tool, the matcher table produced by TableGen can be understood after analysing the source code. I hope get a paper introducing How target select its code and why. <br>

<div dir="ltr">Hi, all !<br>
I am doing some study about code generation in LLVM, It is a
pity that there is little introduction to it. Some paper
introduces that code generation in LLVM is based on Table
Driven, and i have referred paper "<a><font style="font-size:15px"><b>An experiment in <font color="#ff0000"><b>table</b></font> <font color="#ff0000"><b>driven</b></font> <font color="#ff0000"><b>code</b></font> <font color="#ff0000"><b>generation</b></font></b></font></a>",
But it has not given me any help. Can you give a help
understanding the code generation in LLVM. Thanks a lot.<br>

There is some documentation on the Code Generator infrastructure in
the LLVM documentation. Please see:<br>

If you have specific questions about the code generator
infrastructure, please feel free to ask on the mailing list or on
the IRC channel.<br>
