[llvm-dev] Adapting and open-sourcing PGI's Fortran frontend for LLVM

[douglas miles (PGI) via llvm-dev]

Hi Chad - We have a functional Fortran compiler, with the PGI front-end bridged directly to LLVM, all of our Fortran runtime libraries integrated, and the Clang driver adapted for use with the Fortran compiler.  We're working with a few users at DOE who are trying to compile big applications with a binary version of the compiler.  Work is ongoing to migrate the source code into an LLVM-style repository, build infrastructure, documentation and web pages.  All of the compiler and runtime source is now built with Clang or the Fortran front-end with LLVM.  Much work remains on source code refactoring and documentation;  we expect that work to accelerate once all the infrastructure work is done.

Doug

Hi Chad,

I can tell you that progress is being made on PGI's side; I'll let Doug/Rob provide more detailed updates.
