LLAST provides multiple level representations of LLVM.
Usually abstract syntax trees constructed by users in the form of algebraic data types are transformed to LLVM IR.
For Windows users
Use cd LLAST && dotnet publish -c Release -r win10-x64 to create a executable which could compile a LISP dialect into LLVM IR.
See examples at examples/*.lisp.
A set of high level constructs are located at LLAST/Constructs.
