; PA-RISC 2.0 implementation of bn_asm code, based on the
|
|
; 64-bit version of the code. This code is effectively the
|
|
; same as the 64-bit version except the register model is
|
|
; slightly different given all values must be 32-bit between
|
|
; function calls. Thus the 64-bit return values are returned
|
|
; in %ret0 and %ret1 vs just %ret0 as is done in 64-bit
|
|
;
|
|
;
|
|
; This code is approximately 2x faster than the C version
|
|
; for RSA/DSA.
|
|
;
|
|
; See http://devresource.hp.com/ for more details on the PA-RISC
|
|
; architecture. Also see the book "PA-RISC 2.0 Architecture"
|
|
; by Gerry Kane for information on the instruction set architecture.
|
|
;
|
|
; Code written by Chris Ruemmler (with some help from the HP C
|
|
; compiler).
|
|
;
|
