16 | * This is my modest contributon to OpenSSL project (see
|
---|
17 | * http://www.openssl.org/ for more information about it) and is
|
---|
18 | * a drop-in UltraSPARC ISA replacement for crypto/bn/bn_asm.c
|
---|
19 | * module. For updates see http://fy.chalmers.se/~appro/hpe/.
|
---|
20 | *
|
---|
21 | * Questions-n-answers.
|
---|
22 | *
|
---|
23 | * Q. How to compile?
|
---|
24 | * A. With SC4.x/SC5.x:
|
---|
25 | *
|
---|
26 | * cc -xarch=v8plus -c bn_asm.sparc.v8plus.S -o bn_asm.o
|
---|
27 | *
|
---|
28 | * and with gcc:
|
---|
29 | *
|
---|
30 | * gcc -mcpu=ultrasparc -c bn_asm.sparc.v8plus.S -o bn_asm.o
|
---|
31 | *
|
---|
32 | * or if above fails (it does if you have gas installed):
|
---|
33 | *
|
---|
34 | * gcc -E bn_asm.sparc.v8plus.S | as -xarch=v8plus /dev/fd/0 -o bn_asm.o
|
---|
35 | *
|
---|
36 | * Quick-n-dirty way to fuse the module into the library.
|
---|
37 | * Provided that the library is already configured and built
|
---|
38 | * (in 0.9.2 case with no-asm option):
|
---|
39 | *
|
---|
40 | * # cd crypto/bn
|
---|
41 | * # cp /some/place/bn_asm.sparc.v8plus.S .
|
---|
42 | * # cc -xarch=v8plus -c bn_asm.sparc.v8plus.S -o bn_asm.o
|
---|
43 | * # make
|
---|
44 | * # cd ../..
|
---|
45 | * # make; make test
|
---|
46 | *
|
---|
47 | * Quick-n-dirty way to get rid of it:
|
---|
48 | *
|
---|
49 | * # cd crypto/bn
|
---|
50 | * # touch bn_asm.c
|
---|
51 | * # make
|
---|
52 | * # cd ../..
|
---|
53 | * # make; make test
|
---|
54 | *
|
---|
55 | * Q. V8plus architecture? What kind of beast is that?
|
---|
56 | * A. Well, it's rather a programming model than an architecture...
|
---|
57 | * It's actually v9-compliant, i.e. *any* UltraSPARC, CPU under
|
---|
58 | * special conditions, namely when kernel doesn't preserve upper
|
---|
59 | * 32 bits of otherwise 64-bit registers during a context switch.
|
---|
60 | *
|
---|
61 | * Q. Why just UltraSPARC? What about SuperSPARC?
|
---|
62 | * A. Original release did target UltraSPARC only. Now SuperSPARC
|
---|
63 | * version is provided along. Both version share bn_*comba[48]
|
---|
64 | * implementations (see comment later in code for explanation).
|
---|
65 | * But what's so special about this UltraSPARC implementation?
|
---|
66 | * Why didn't I let compiler do the job? Trouble is that most of
|
---|
67 | * available compilers (well, SC5.0 is the only exception) don't
|
---|
68 | * attempt to take advantage of UltraSPARC's 64-bitness under
|
---|
69 | * 32-bit kernels even though it's perfectly possible (see next
|
---|
70 | * question).
|
---|
71 | *
|
---|
72 | * Q. 64-bit registers under 32-bit kernels? Didn't you just say it
|
---|
73 | * doesn't work?
|
---|
74 | * A. You can't address *all* registers as 64-bit wide:-( The catch is
|
---|
75 | * that you actually may rely upon %o0-%o5 and %g1-%g4 being fully
|
---|
76 | * preserved if you're in a leaf function, i.e. such never calling
|
---|
77 | * any other functions. All functions in this module are leaf and
|
---|
78 | * 10 registers is a handful. And as a matter of fact none-"comba"
|
---|
79 | * routines don't require even that much and I could even afford to
|
---|
80 | * not allocate own stack frame for 'em:-)
|
---|
81 | *
|
---|
82 | * Q. What about 64-bit kernels?
|
---|
83 | * A. What about 'em? Just kidding:-) Pure 64-bit version is currently
|
---|
84 | * under evaluation and development...
|
---|
85 | *
|
---|
86 | * Q. What about shared libraries?
|
---|
87 | * A. What about 'em? Kidding again:-) Code does *not* contain any
|
---|
88 | * code position dependencies and it's safe to include it into
|
---|
89 | * shared library as is.
|
---|
90 | *
|
---|
91 | * Q. How much faster does it go?
|
---|
92 | * A. Do you have a good benchmark? In either case below is what I
|
---|
93 | * experience with crypto/bn/expspeed.c test program:
|
---|
94 | *
|
---|
95 | * v8plus module on U10/300MHz against bn_asm.c compiled with:
|
---|
96 | *
|
---|
97 | * cc-5.0 -xarch=v8plus -xO5 -xdepend +7-12%
|
---|
98 | * cc-4.2 -xarch=v8plus -xO5 -xdepend +25-35%
|
---|
99 | * egcs-1.1.2 -mcpu=ultrasparc -O3 +35-45%
|
---|
100 | *
|
---|
101 | * v8 module on SS10/60MHz against bn_asm.c compiled with:
|
---|
102 | *
|
---|
103 | * cc-5.0 -xarch=v8 -xO5 -xdepend +7-10%
|
---|
104 | * cc-4.2 -xarch=v8 -xO5 -xdepend +10%
|
---|
105 | * egcs-1.1.2 -mv8 -O3 +35-45%
|
---|
106 | *
|
---|
107 | * As you can see it's damn hard to beat the new Sun C compiler
|
---|
108 | * and it's in first place GNU C users who will appreciate this
|
---|
109 | * assembler implementation:-)

113 | * Revision history.
|
---|
114 | *
|
---|
115 | * 1.0 - initial release;
|
---|
116 | * 1.1 - new loop unrolling model(*);
|
---|
117 | * - some more fine tuning;
|
---|
118 | * 1.2 - made gas friendly;
|
---|
119 | * - updates to documentation concerning v9;
|
---|
120 | * - new performance comparison matrix;
|
---|
121 | * 1.3 - fixed problem with /usr/ccs/lib/cpp;
|
---|
122 | * 1.4 - native V9 bn_*_comba[48] implementation (15% more efficient)
|
---|
123 | * resulting in slight overall performance kick;
|
---|
124 | * - some retunes;
|
---|
125 | * - support for GNU as added;
|
---|
126 | *
|
---|
127 | * (*) Originally unrolled loop looked like this:
|
---|
128 | * for (;;) {
|
---|
129 | * op(p+0); if (--n==0) break;
|
---|
130 | * op(p+1); if (--n==0) break;
|
---|
131 | * op(p+2); if (--n==0) break;
|
---|
132 | * op(p+3); if (--n==0) break;
|
---|
133 | * p+=4;
|
---|
134 | * }
|
---|
135 | * I unroll according to following:
|
---|
136 | * while (n&~3) {
|
---|
137 | * op(p+0); op(p+1); op(p+2); op(p+3);
|
---|
138 | * p+=4; n=-4;
|
---|
139 | * }
|
---|
140 | * if (n) {
|
---|
141 | * op(p+0); if (--n==0) return;
|
---|
142 | * op(p+2); if (--n==0) return;
|
---|
143 | * op(p+3); return;
