[cfe-dev] AST Writer

[Ridwan Shariffdeen via cfe-dev]

Hi Madhur,

Thank you for the reply.
I am currently working on AST mutation and need this feature to insert
custom nodes. If I have to use IR I will have to translate the AST
mutations into IR level code and redo. Or is there a tool which I can use
to translate AST diff into IR instructions?



Regards
