Compilation:

g++ faust-llvm.cpp /usr/local/lib/libfaust.a `llvm-config --ldflags --libs all` -lz -lcurses -o faust-llvm-static
g++ faust-llvm.cpp -lfaust -L /usr/local/lib `llvm-config --ldflags --libs all` -lz -lcurses -o faust-llvm-shared

Usage (possibly with explicit parameters given to the compiler) : 

./faust-llvm-static karplus.dsp
./faust-llvm-static -vec -lv 1 karplus.dsp
./faust-llvm-static -double -vec -lv 0 -vs 64 karplus.dsp
