4 ; Character specification table.
7 ; The tables are readonly, put them into the rodata segment
11 ; The following 256 byte wide table specifies attributes for the isxxx type
12 ; of functions. Doing it by a table means some overhead in space, but it
13 ; has major advantages:
15 ; * It is fast. If it were'nt for the slow parameter passing of cc65, one
16 ; could even define macros for the isxxx functions (this is usually
17 ; done on other platforms).
19 ; * It is highly portable. The only unportable part is the table itself,
20 ; all real code goes into the common library.
22 ; * We save some code in the isxxx functions.
30 ; 3 - Hex digit (both, lower and upper)
31 ; 4 - Control character
32 ; 5 - The space character itself
33 ; 6 - Other whitespace (that is: '\f', '\n', '\r', '\t' and '\v')
34 ; 7 - Space or tab character
40 .repeat 2 ; 2 times for normal and inverted
