fixed-point number could be stored in LLVM first class integer types. i cannot see the problem now. but to be type-safe, there should be a first class 'fixed'. some llvm extensions required to mapping dsp-c lanaguages could be implemented as qualifiers. 1. _sat qualifier Saturate the result within [0.0, +1.0> or [-1.0,+1.0> (unsigned/singed). sat signed fixed a; sat signed fixed
