[cfe-dev] main functions of clang

[eyasu getahun]

Hello James,

Thanks a lot for your help and sorry for my late reply. Your information is
helpful, however what I want to know is the main method of clang that calls
the printpretty() function. As you mentioned, lets have S
->printpretty(context). We can see this at StmtPrinter.cpp  class as I
mentioned earlier. My question is which main method of clang this function
is called. As we know at run time there is at least on main method that
calls other functions. Assume we want to print the source code of AST. We
will run clang on command line. we will use a command(I don't know the
command) that calls the print pretty function. Hope you get my idea. So,
which main method/function of clang is calling this function? Thanks again.
