I looked at a way to start generating ASR using AST, but I would need some guidance to start off. I will be meeting with my mentor and starting to get some headway this week.
GSOC 2022 - LFortran - Implementing Generics Final report - Oshanath Rajawasam Mentors : Ondřej Čertík, Gagandeep Singh Overview This project was about implementing generics for LFortran. This project was implemented parallelly to the same project on LPython, so a lot of the same code is reused. The LPython counterpart was developed by Luthfan Lubis and it has progressed further than this project. Reason for the Project Functions and subroutines in Fortran have specific parameter types and return types associated with them. Since LFortran, at its core, is the same as Fortran, this is also the case for LFortran. This can be problematic when the application demands template-like structures. For example, when implementing a function to add 2 numbers, with current tools available, we would have to implement the same function for all data types it is intended to be used. But with templates, we can define the function once, and use it with any data type we w...
2022-07-22-progress report 6 I wrote code to generate ASR from AST this week. It is an initial implementation so it's not complete. I had to make some changes to the example "swap_m.f90" since I couldn't get the interface working. I will work on it in a future week. The general approach I took is I added a symbol table to the Template since it will contain functions and subroutines (program units) as well as derived types. I also ignored restrictions and TypeParameter for now. The first item of the Short term TODO list of this PR is now complete.
2022-08-19-progress report 10 This week I converted my PR Merging function and TemplatedFunction by Oshanath · Pull Request #90 · lfortran/lfortran (github.com) into a mergeable state by cleaning the history and updating the reference tests to reflect the changes to ASR and AST with instantiation. Then the PR was merged.
