I had been a novice user of LLVM in 2013–2014 as a Rust contributor but since then I have not worked on LLVM-related projects. I completed Kaleidoscope and had little experience on platform-specific things but was not an LLVM expert at all.
Recently, my interest in LLVM has revived thanks to MLIR and CIRCT. However, as they are especially new topics, no user guides or such are available on them. (I have to relearn LLVM in general, too.)
Would you suggest some pointers to catch up with the current landscape of the LLVM ecosystem? LLVM Weekly is of course an excellent resource, but I want to know if anyone has additional recommendations.
