[LLVMdev] dragon egg + llvm for fortran to c translation

[Philipp Schwaha]

Thank you for your reply Dmitry!

It would not be too great a deal, if I need to use previous versions as
long as it would get the desired results :)
Would the code from the IR be portable to different C compilers? I
guess the resulting C code will not have too much resemblance to the input?

cheers
