- ; * 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:
