V8plus achitecture? What kind of beast is that? + * A. Well, it's rather a programming model than an architecture... + * It's actually v9-compliant, i.e. *any* UltraSPARC, CPU under + * special conditions, namely when kernel doesn't preserve upper + * 32 bits of otherwise 64-bit registers during a context switch. + * + * Q. Why just UltraSPARC? What about SuperSPARC? + * A. Original release did target UltraSPARC only. Now SuperSPARC + * version is provided along. Both version share bn_*comba[48] + * implementations (see comment later in code for explanation). + * But what's so special about this UltraSPARC implementation? + * Why didn't I let compiler do the job? Trouble is that most of + * available compilers (well, SC5.0 is the only exception) don't + * attempt to take advantage of UltraSPARC's 64-bitness under + * 32-bit kernels even though it's perfectly possible (see next + * question). + * + * Q. 64-bit registers under 32-bit kernels? Didn't you just say it + * doesn't work? + * A. You can't adress *all* registers as 64-bit wide:-( The catch is + * that you actually may rely upon %o0-%o5 and %g1-%g4 being fully + * preserved if you're in a leaf function, i.e. such never calling + * any other functions. All functions in this module are leaf and + * 10 registers is a handful. And as a matter of fact none-"comba" + * routines don't require even that much and I could even afford to + * not allocate own stack frame for 'em:-) + * + * Q. What about 64-bit kernels? + * A. What about 'em? Just kidding:-) Pure 64-bit version is currently + * under evaluation and development... + * + * Q. What about shared libraries? + * A. What about 'em? Kidding again:-) Code does *not* contain any + * code position dependencies and it's safe to include it into + * shared library as is. + * + * Q. How much faster does it go? + * A. Do you have a good benchmark?
