Hi everyone, Jeff Garzik and myself have been hacking on LLVM backed for Sparse. The sources are available on Github: git clone git://github.com/penberg/sparse-llvm.git You can use sparse-llvm with the 'sparsec' shells script provided in the source tree. It has a GCC compatible command line interface and uses GCC for linking. For example, you can try to build sparse with sparse-llvm like this: make CC=sparsec Developers who are interested in looking at the LLVM output can use the 'sparse-llvm' command as follows: sparse-llvm foo.c | llvm-dis The backend is already capable of generating code for simple C code on various platforms. Supported C features include: * Function calls * Switch statements * if-else statements * Arithmetic operations * Bitwise operations * Floating point arithmetic There's many features that are not supported so if you see an error message such as this while compiling a C file: sparse-llvm: sparse-llvm.c:165: pseudo_type: Assertion `0' failed. don't panic because it simply means you're attempting to use an unsupported feature. Help implementing them is more than welcome!
