* 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
|
1999-07-25 12:34:30 +00:00
|
|
|
* (in 0.9.2 case with no-asm option):
|
1999-05-04 20:35:18 +00:00
|
|
|
*
|
|
|
|
|
* # 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...
|
1999-05-04 20:35:18 +00:00
|
|
|
* 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?
|
2013-06-12 23:22:32 +00:00
|
|
|
* A. You can't address *all* registers as 64-bit wide:-( The catch is
|
1999-05-04 20:35:18 +00:00
|
|
|
* 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?
|
1999-05-05 11:27:56 +00:00
|
|
|
* A. What about 'em? Just kidding:-) Pure 64-bit version is currently
|
1999-05-04 20:35:18 +00:00
|
|
|
* under evaluation and development...
|
|
|
|
|
*
|
1999-05-05 11:27:56 +00:00
|
|
|
* Q. What about shared libraries?
|
1999-05-04 20:35:18 +00:00
|
|
|
* A. What about 'em? Kidding again:-) Code does *not* contain any
|
|
|
|
|
* code position dependencies and it's safe to include it into
|
1999-05-05 11:27:56 +00:00
|
|
|
* shared library as is.
|
1999-05-04 20:35:18 +00:00
|
|
|
*
|
1999-05-05 11:27:56 +00:00
|
|
|
* Q. How much faster does it go?
|
1999-05-04 20:35:18 +00:00
|
|
|
* 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
|
1999-05-05 11:27:56 +00:00
|
|
|
* and it's in first place GNU C users who will appreciate this
|
1999-05-04 20:35:18 +00:00
|
|
|
* assembler implementation:-)

|
|
|
|
|
* }
|
|
|
|
|
* I unroll according to following:
|
|
|
|
|
* while (n&~3) {
|
|
|
|
|
