MS demangle errors while building TAPA

[vkomenda]

How to bypass compilation of MicrosoftDemangle.cpp? I'm getting those errors again:

I suspect this is the same issue as https://github.com/facebook/hermes/issues/261; you need to add #include <cstdint> to the llvm/include/llvm/Demangle/MicrosoftDemangleNodes.h file.

Is it possible to upgrade the LLVM dependency? It's really old. Including cstdint doesn't fix all errors.

tapa/build/_deps/llvm-src/llvm/include/llvm/Demangle/MicrosoftDemangleNodes.h:241:8: error: ‘string’ in namespace ‘std’ does not name a type
  241 |   std::string toString(OutputFlags Flags = OF_Default) const;
      |        ^~~~~~

I tried LLVM 11 and 15. I think either can work. I'm only getting undefined references to Google logging. Not sure how to fix that right now.

Did you try #include <string>?

I'd be happy to merge if you can do another PR😁

LLVM is now compiled using reproducible toolchains with Bazel.
