Freestanding Support #272

Open Immortalin opened 7 years ago

Immortalin commented 7 years ago

Hi! Is it possible to add support for freestanding compilation target? i.e. bare metal. This would make it possible to run Fortran on many embedded and real time systems

What do you have in mind?

Immortalin commented 6 years ago

Many embedded systems don't have full POSIX access. Would be nice if flang allows manual definition of primitives etc. in a separate file. Rust and C address this issue pretty well.
