Overview of Work Done

Hi All,

I’m Anutosh, a core developer on clang/clang-repl and part of Project Jupyter. Previously I was a member at another LLVM-based Fortran compiler, LFortran .

I had presented the above idea in the previous flang biweekly meeting and was advised to frame a RFC for the same.

Problem Statement

The Fortran ecosystem still lacks a modern, interactive workflow—something equivalent to a REPL or an Interpreter that many other LLVM-based languages now support. This limits rapid prototyping, teaching, exploratory numerical work, and smooth integration with tools like Jupyter.

	#include <libasr/pass/replace_symbolic.h>
	#include <libasr/pass/pass_utils.h>
	#include <libasr/pass/intrinsic_function_registry.h>

	#include <vector>

	So I've made enough progress and I currently have enough understanding of what's
	happening to share it with you. I can't invest more time on this than what I've
	already be doing, hopefully this is going to put you on track.

	= Why do we have this -isystem /usr/include?

	emcmake passes a toolchain file (cmake/Modules/Platform/Emscripten.cmake) to
	cmake that informs it about the toolchain. In the process it sets
	CMAKE_CROSSCOMPILING=ON.
