Basically, besides what you've already found out, what needs tuning is provide some basic support for inline assembly in cln/src/base/cl_low.h. That probably looks worse than it actually is. It can either be guessed by looking at GCC's .md file or maybe be lifted from GMP or Pari. At least the mulu64 macro needs to be implemented. If possible, more. Defining mulu64 for ia64 gave approximately a factor two speedup on itanic. Defining all the ones that are defined for x86_64 gave a factor three or more, on that architecture. There's a lot of hidden potential here. Also, I'ld like to ask some basic quality questions. Does it work with: * configure --disable-shared and --disable-static * configure --without-gmp and default with gmp and are the sizes of the basic types in intparam.h the same in both cases? If not, maybe something should be fixed. * CXXFLAGS set to "-fno-exceptions -O2" and "-O1". Does make check work with some or possibly all of the 2^3 combinations of the above? You could start answering the last question. If you're daring, feel free to tackle the other ones. Otherwise, I'ld need access to a machine. Regards -richy. -- Richard B.
