(I had no idea what was an appropriate topic for this to go under, this seemed like the best option) just today I tried using polly with clang to compile something. I tried testing it first on a basic C file with only a main function and print, trying to compile it via

clang -O3 -mllvm -polly file.c

only returned an error saying llvm option parser couldn't recognize -polly. the llvm wiki says llvm and its tools have to all be built in the same revision in order for clang and polly to work together, I'd assume this was the case since llvm and its tools all come from one PKGBUILD in arch repos. am I doing something wrong or is this a known issue?
