If that's the case, then we need to test every single LLVM version between 10 - 18. I was hoping we could perhaps skip some, but I guess we cannot.

I think this is fine. I am happy to adjust the required tests. Shouldn't we remove the number of tests, or do you want to do it later?

Currently I see 31 total tests. We should disable Appveyor also. See https://github.com/symengine/symengine/issues/2020, we should only do around 10 tests or so, if possible. Do you see ways to reduce...

This issue is a hard issue, as it involves figuring out what we should do. It's a very low priority one. I recommend choosing some other one.

This is an internal error, the 19 is an ASR node, in this case an `expr` (I think), counted from here: https://github.com/lfortran/lfortran/blob/576604da7068bcd5c7ae191ff61a0edcc35be5ca/src/libasr/ASR.asdl#L79, so if I count correctly, it's `UnsignedIntegerBitNot` that...

@harperjf awesome, thanks for this!

Possibly. For constants we do compile time evaluation of the intrinsics, so perhaps there is a bug in it.

@michaelwcl the best request in this case is to send a PR with the implementation. :) Thanks for using SymEngine. If you find other issues, please report them, and if...

The linking used to work, so you have to go back to the last working state and figure out if it was a workaround or an LFortran commit that caused...

Then go to a previous LFortran commit and find one that works. Then use bisection to figure out which commit broke it.
