What do you think would be the proper way to detect the cpu features, and add support for runtime reconfiguration? Maybe there should be some kind of call, like jit_get_cpu_features(), that one should call before generating code, so that the macros jit_sse_p(), jit_i686_p(), etc, could actually be runtime flags. Also, it may be desirable to allow changing these flags, mainly for testing purposes.
Looks like a good idea. I still haven't reviewed the branch though. Paolo
