+/*
+ * This is my modest contributon to OpenSSL project (see
+ * http://www.openssl.org/ for more information about it) and is
+ * a drop-in UltraSPARC ISA replacement for crypto/bn/bn_asm.c
+ * module. For updates see http://fy.chalmers.se/~appro/hpe/.
+ *
+ * Questions-n-answers.
+ *
+ * Q. How to compile?
+ * A. With SC4.x/SC5.x:
+ *
+ * cc -xarch=v8plus -c bn_asm.sparc.v8plus.S -o bn_asm.o
+ *
+ * and with gcc:
+ *
+ * gcc -mcpu=ultrasparc -c bn_asm.sparc.v8plus.S -o bn_asm.o
+ *
+ * or if above fails (it does if you have gas installed):
+ *
+ * gcc -E bn_asm.sparc.v8plus.S | as -xarch=v8plus /dev/fd/0 -o bn_asm.o
+ *
+ * Quick-n-dirty way to fuse the module into the library.
+ * Provided that the library is already configured and built
+ * (in 0.9.2 case with no-asm option):
+ *
+ * # cd crypto/bn
+ * # cp /some/place/bn_asm.sparc.v8plus.S .
+ * # cc -xarch=v8plus -c bn_asm.sparc.v8plus.S -o bn_asm.o
+ * # make
+ * # cd ../..
+ * # make; make test
+ *
+ * Quick-n-dirty way to get rid of it:
+ *
+ * # cd crypto/bn
+ * # touch bn_asm.c
+ * # make
+ * # cd ../..
+ * # make; make test
+ *
+ * Q. 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? In either case below is what I
+ * experience with crypto/bn/expspeed.c test program:
+ *
+ * v8plus module on U10/300MHz against bn_asm.c compiled with:
+ *
+ * cc-5.0 -xarch=v8plus -xO5 -xdepend +7-12%
+ * cc-4.2 -xarch=v8plus -xO5 -xdepend +25-35%
+ * egcs-1.1.2 -mcpu=ultrasparc -O3 +35-45%
+ *
+ * v8 module on SS10/60MHz against bn_asm.c compiled with:
+ *
+ * cc-5.0 -xarch=v8 -xO5 -xdepend +7-10%
+ * cc-4.2 -xarch=v8 -xO5 -xdepend +10%
+ * egcs-1.1.2 -mv8 -O3 +35-45%
+ *
+ * As you can see it's damn hard to beat the new Sun C compiler
+ * and it's in first place GNU C users who will appreciate this
+ * assembler implementation:-)
+ */
+
+/*
+ * Revision history.
+ *
+ * 1.0 - initial release;
+ * 1.1 - new loop unrolling model(*);
+ * - some more fine tuning;
+ * 1.2 - made gas friendly;
+ * - updates to documentation concerning v9;
+ * - new performance comparison matrix;
+ * 1.3 - fixed problem with /usr/ccs/lib/cpp;
+ * 1.4 - native V9 bn_*_comba[48] implementation (15% more efficient)
+ * resulting in slight overall performance kick;
+ * - some retunes;
+ * - support for GNU as added;
+ *
+ * (*) Originally unrolled loop looked like this:
+ * for (;;) {
+ * op(p+0); if (--n==0) break;
+ * op(p+1); if (--n==0) break;
+ * op(p+2); if (--n==0) break;
+ * op(p+3); if (--n==0) break;
+ * p+=4;
+ * }
+ * I unroll according to following:
+ * while (n&~3) {
+ * op(p+0); op(p+1); op(p+2); op(p+3);
+ * p+=4; n=-4;
+ * }
+ * if (n) {
+ * op(p+0); if (--n==0) return;
+ * op(p+2); if (--n==0) return;
+ * op(p+3); return;
+ * }
