; The tables are readonly, put them into the rodata segment
.rodata
; The following 256 byte wide table specifies attributes for the isxxx type
; of functions. Doing it by a table means some overhead in space, but it
; has major advantages:
;
; * It is fast. If it were'nt for the slow parameter passing of cc65, one
; could even define macros for the isxxx functions (this is usually
; done on other platforms).
;
; * It is highly portable. The only unportable part is the table itself,
; all real code goes into the common library.
;
; * We save some code in the isxxx functions.
