Another possible change might be moving the initialized filed outside the __gmpn_cpuvec struct. I mean: if we have a global __gmpn_cpuvec_initialized variable, instead of the field __gmpn_cpuvec.initialized of a global struct, we can easily hide it with a local declaration. E.g: all the code calling toom3 checks the thresholds before calling, so we can safely assume that _cpuvec is intitialised when we are inside the function. I.e: a simple "const int __gmpn_cpuvec_initialized = 1;" in toom33_mul.c can safely reduce branches and code size for fat builds. Please tell me if this can be too dangerous or I can try the trick.
