1 ;
2 ; PA-RISC 2.0 implementation of bn_asm code, based on the
3 ; 64-bit version of the code. This code is effectively the
4 ; same as the 64-bit version except the register model is
5 ; slightly different given all values must be 32-bit between
6 ; function calls. Thus the 64-bit return values are returned
7 ; in %ret0 and %ret1 vs just %ret0 as is done in 64-bit
8 ;
9 ;
10 ; This code is approximately 2x faster than the C version
11 ; for RSA/DSA.
12 ;
13 ; See http://devresource.hp.com/ for more details on the PA-RISC
14 ; architecture. Also see the book "PA-RISC 2.0 Architecture"
15 ; by Gerry Kane for information on the instruction set architecture.
16 ;
17 ; Code written by Chris Ruemmler (with some help from the HP C
18 ; compiler).
19 ;
20 ; The code compiles with HP's assembler

30 ; Some information about HP's runtime architecture for 32-bits.
31 ;
32 ; "Caller save" means the calling function must save the register
33 ; if it wants the register to be preserved.
34 ; "Callee save" means if a function uses the register, it must save
35 ; the value before using it.
36 ;
37 ; For the floating point registers
38 ;
39 ; "caller save" registers: fr4-fr11, fr22-fr31
40 ; "callee save" registers: fr12-fr21
41 ; "special" registers: fr0-fr3 (status and exception registers)
42 ;
43 ; For the integer registers
44 ; value zero : r0
45 ; "caller save" registers: r1,r19-r26
46 ; "callee save" registers: r3-r18
47 ; return register : r2 (rp)
48 ; return values ; r28,r29 (ret0,ret1)
49 ; Stack pointer ; r30 (sp)
50 ; millicode return ptr ; r31 (also a caller save register)
