#LLVM codegen and native runtime for Idris 2

This is a (work in progress) backend to generate native executables from Idris code, using the LLVM compiler infrastructure. Code is generated via LLVM IR (i.e. not via generated C source code).

The source folder rts/ contains a primitive runtime system with a relocating semi-space garbage collector.

#Prerequisites

LLVM 11 needs to be installed and the binaries available in your $PATH. To check if that is the case, try the following command:

$ opt --version
LLVM (http://llvm.org/):
  LLVM version 11.1.0

  Optimized build.
  Default target: x86_64-pc-linux-gnu
  Host CPU: znver2

GMP needs to be installed (libgmp-dev on Debian).

#Compiling

$ make
$ make test

#Using

# compile the included "Hello world" example
./build/exec/rapidc --cg llvm -o hello samples/Hello.idr
# run the compiled binary
./build/exec/hello
