I learned a lot about LLVM by looking at the compiler output from Clang:

  clang -emit-llvm -S sample.cpp

The article mentions Clang's AST, which can also be emitted:

  clang -Xclang -ast-dump -fsyntax-only sample.cpp

And for checking compiler outputs across lots of languages and implementations, there's always Matt Godbolt's Compiler Explorer:
