Re: LLVM from a Go Perspective
#2Hmm, not sure I agree that LLVM has little documentation. My experience using it has been pretty smooth.
Regardless, compiling functions from a language you know to LLVM IR is a good way to learn how IR works. You can do this for C(++) with the clang --emit-llvm switch. In addition, many optimizers in LLVM are geared towards the IR patterns clang emits.

The TinyGo project is interesting, but it is not a new language developed by a single person as Go is not a new language.
Wondering is there any such single person project implementing a compiler for a new language using LLVM and delivering close to C performance?

If you're working at the IR level, then there's usually pretty good documentation in terms of the doxygen and various pages explaining things.
But if you start venturing down into the backend, a lot of gotchas are never documented anywhere, just somehow learned through osmosis from another backend author or looking up code snippets from another implemented backend.

xtlang is one; ML meets C with S-expressions and hot reloading.

Sure; the article was about building compilers rather than backends. FWIW I looked briefly into building a LLVM backend (IR subset) for a DSP chip, and gave up partly for the reasons you mentioned.

As far as I know, it's mostly Andrew Kelley[1] working on Zig, though it seems to be growing quickly now!

Any reference for C-like performance?

Not a new language, as it’s based on/similar to Ruby syntax, but the latter is interpreted while this one is built from the ground up for compilation/LLVM:
