[cfe-dev] Parse an ast file using compiler instance

[kwadwo amankwa]

Hi ,
I'm writing a small program that transforms  source into an AST file 
(for merging with other files later) . I am now trying to read the ast 
file , and parse the AST. I have been able to read the file into an 
ASTUnit object and am now  trying to parse the AST using a compiler 
instance .


I have already written a front-end action, ast consumer and a recursive 
visitor and have attempted to parse the ast using the method from the 
Recursive Visitor tutorial but to no avail. Can anyone show me how I 
would parse an ast  using the ASTUnit and Compiler Instance(If that is 
the right way)?
