Dear Stefanos,

Thanks a lot. I have one more question. If an optimization pass is attempted on a source code and assume the pass is buggy, is it worthwhile to find out which optimization (e.g., code motion, scalar replacement, etc) is responsible for the bug ?

Thanks again for your help.

I find the course by Adrian Sampson useful

Hi Sudakshina,

First of all, a pass is not supposed to be buggy. However, if some pass is in fact buggy, finding which one, is worth it depends on your motive.
For example, if you want to help the LLVM community, yes that would be worth it.

Best,
Stefanos
