; * the assembly routines are written in this separate .s file because EVC++ won't inline...
; *
; * Notes on APCS (ARM procedure call standard):
; *  - first four arguments are in r0-r3
; *  - additional argumets are pushed onto stack in reverse order
; *  - return value goes in r0
; *  - routines can overwrite r0-r3, r12 without saving
; *  - other registers must be preserved with stm/ldm commands
; * 
; * Equivalent register names:
; *
; * r0  r1  r2  r3  r4  r5  r6  r7  r8  r9  r10 r11 r12 r13 r14 r15
