Linking errors when moving to LLVM 14.0.6

[kathlenehurt-sifive]

I'm attempting to update this library to use LLVM 14.0.6. I can compile the plugin and runtime library, but I encounter a linking error when attempting to build the easyjit-example test:

Undefined symbols for architecture arm64:
  "char* easy::layout::serialize_arg<char const*>(char const*)", referenced from:
      void* easy::layout::get_layout<char const*>() in camfilter.cpp.o
  "char* easy::layout::serialize_arg<unsigned char const*>(unsigned char const*)", referenced from:
      void* easy::layout::get_layout<unsigned char const*>() in camfilter.cpp.o
  "char* easy::layout::serialize_arg<unsigned char*>(unsigned char*)", referenced from:
      void* easy::layout::get_layout<unsigned char*>() in camfilter.cpp.o
  "char* easy::layout::serialize_arg<unsigned int>(unsigned int)", referenced from:
      void* easy::layout::get_layout<unsigned int>() in camfilter.cpp.o
ld: symbol(s) not found for architecture arm64

Is this repo still being maintained?

Hi!
Thank you so much for your effort. Unfortunately the library is not being maintained anymore since I didn't got much time to evolve it.

I'll book some time this week to finish moving it to LLVM 14 if that's ok.

Just out of curiosity, are you planning to use easy::jit for anything in particular?

@jmmartinez that would be GREATLY appreciated!

Yes, I'm developing a RISC-V functional model and am planning to use JIT to improve the simulator's performance.

@kathlenehurt-sifive I've advanced a bit but there is a ton of work to do (updating usage of llvm api's and cmake scripts). I'm going on vacations next week so I won't be able to advance soon.

Just in case, keep in mind that this project is a PoC and never reached "industrial" quality.
