; Formatted Debug Output (FDO)
; Copyright (c) 2005-2006, mike.dld
; Created: 2005-01-29, Changed: 2006-11-10
;
; For questions and bug reports, mail to mike.dld@gmail.com
;
; Available format specifiers are: %s, %d, %u, %x (with partial width support)
;
; to be defined:
; __DEBUG__ equ 1
; __DEBUG_LEVEL__ equ 5
; MOV Immediate.
; Useful for things like movi eax,10:
; shorter than regular mov, but slightly slower,
; do not use it in performance-critical places.
