[cfe-dev] AST Writer

[Matthieu Brucher via cfe-dev]

It's odd though, because generating code on the fly would be easier on the
AST than on the IR tree, if the goal is JIT and also saving the code at the
same time.
It's probably also easier also to generate properly formatted code?

Regards,

Matthieu
