-; 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
-;
-
- .level 2.0W
- .space $TEXT$
- .subspa $CODE$,QUAD=0,ALIGN=8,ACCESS=0x2c,CODE_ONLY
-
-;
-; Global Register definitions used for the routines.
-;
-; Some information about HP's runtime architecture for 64-bits.
-;
-; "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
-;
-; "caller save" registers: fr4-fr11, fr22-fr31
-; "callee save" registers: fr12-fr21
-; "special" registers: fr0-fr3 (status and exception registers)
-;
-; For the integer registers
-; value zero : r0
-; "caller save" registers: r1,r19-r26
-; "callee save" registers: r3-r18
-; return register : r2 (rp)
-; return values ; r28 (ret0,ret1)
-; Stack pointer ; r30 (sp)
-; global data pointer ; r27 (dp)
-; argument pointer ; r29 (ap)
