VAST is an experimental compiler pipeline designed for program analysis of C and C++. It provides a tower of IRs as MLIR dialects to choose the best fit representations for a program analysis or further program abstraction.

Most languages target C or LLVM, and C and LLVM have a fundamentally lossy compilation processes.
To get around this, you'd need a hodge podge of pre compiler directives, or take a completely different approach.
I found a cool project that uses a "Tower of IRs" that can restablish source to binary provenance, which, seems to me, to be on the right track:

I'd definitely like to see the compilation processes be more transparent and easy to work with.
