Hey there 🤗, Welcome to my GSoC Journey

This is a series of blogs that I am writing to share my amazing GSoC 22 (Google Summer of Code 2022) Journey with you all.

Enabling LLVM Based WASM Backend and Build LFortran to WASM

Once we had testing enabled for the wasm-wat backends, our next goals were

  1. To Enable LLVM based WASM Backend
  2. To Compile LFortran to WASM

The LLVM based WASM backend is usefull for the release mode of LFortran, as it could generate a fast binary (although compilation may be slow). A Challenge here is to get the C runtime library working.

Enabling LLVM based WASM Backend was perviously tried at !1385. I tried exaclty the same steps as in the MR !1768, but no luck. After much trial and error of trying different tools and different commands for those tools, I found a way to use emscripten to achieve our target. Some test cases compile and run smoothly, where as, some throw a warning/error about mismatch in function signatures. More details about this is available on the same MR !1768

This phase was mostly/approximately from 05-06-2022 to 12-06-2022.

The MRs during this phase are as follows:

I also tried to build/compile LFortran to wasm during this phase. It seems to work. I am yet to make an official MR regarding the same. I will update here as soon as I make a MR.

Update: I made an official MR at !1796 WASM: Compile/Build LFortran to WASM (also updated in the above MRs list).

That’s all for this blog. Thank you for your time. We continue this series in the next blog.
