; PA-RISC 64-bit implementation of bn_asm code |
|
; |
|
; 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). |
|
; |
|
; The code compiles with HP's assembler |

; "Caller save" means the calling function must save the register |
|
; if it wants the register to be preserved. |
|
; "Callee save" means if a function uses the register, it must save |
|
; the value before using it. |

|
; For the floating point registers |
|
