  • vast

    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.

  • ipr

    Compiler-neutral Internal Program Representation for C++

    • Project mention: Module interfaces for pre-built libraries | /r/cpp | 2023-04-26

    I'm not sure about clang or gcc. For VS, u/GabrielDosReis might be able to speak to the .ifc IPR stability/volatility. My wager (deferring to him to correct me) is that the IPR is still changing over time but will stabilize more over time.
