LFortran Intrinsic Functions

This project delves into the intricate landscape of intrinsic functions within LFortran, evaluating their current status and proposing strategic enhancements. To enhance efficiency, certain functions require migration from the old runtime and compile-time libraries to become intrinsic functions, while others need to be developed anew. Additionally, there are intrinsic functions that fall outside the scope of this project; they will be flagged with an error message indicating their non-implementation status. The methodology to implement an intrinsic function from scratch is also elucidated, outlining a structured approach to integrate new functionalities. Ideas related to design improvements and enhancing performance has also been proposed.
