[llvm-dev] RFC: A binary serialization format for MemProf
Hi Andrey, The serialization format is language independent, though our focus is C/C++. Note that our instrumentation is based on the LLVM sanitizer infrastructure and should work for Rust (supports building with sanitizers [1]). We have not considered using the data profile for non-C/C++ codes.

I was going to respond similarly, and add a note that it isn't clear that gollvm (LLVM-based Go compiler) supports either PGO or the sanitizers, so that may be more difficult than Rust which does. As Snehasish notes, we are focused on C/C++, but this will all be done in the LLVM IR level and should be language independent in theory.
