This repository provides a toolchain for writing C++ macros using Racket's excellent macro facilities.
This requires building our fork of llvm / clang. See this page for help doing so, substituting the forks referenced by this repository where necessary. You'll also need to add the Cxx directory from this repository as a collection to your installation of racket. See this page for helping doing so.
Once you've done both, you can use compile-cxx.rkt to work with the toolchain. An example invocation is as follows:
compile-cxx.rkt -t -u -f -arch -f i386 -f -v -f -stdlib=libstdc++ -f --std=c++11 -f -L/Developer/NVIDIA/CUDA-7.5/lib -f -lcudart -f -lcudadevrt -S "SkelImpls" -@ Min Math.rkt -@ Repeat LexicalUnroll.rkt -@ CuFunc CuFunc.rkt -@ Reinclude Reinclude.rkt -b "llvm/build/Debug/bin/" -I /Developer/NVIDIA/CUDA-7.5/include -I includes/ test-params.json demos/reduce.skel
The -t flag instructs the toolchain to leave temporary files in place, so you can inspect intermediate products. This is useful for interactively debugging individual components in DrRacket.
