Yesterday support for _Bool (and via stdbool.h bool) has been added to the Z80 port. This is the most complete support for bool in any sdcc port for now. bool should work just like the standard requires, including support for arrays of bool and using bool inside a struct.
Support for _Bool/bool is enabled when compiling using --std-c99 or --std-sdcc99. Developers that have been using another type of variable (e.g. unsigned char) for condition variables are encouraged to try the new bool. sdcc can generate faster, more compact code when using bool (e.g. negation is implemented as a simple xor with 1). Another example: Conditional jumps if(x) for x of type unsigned char: xor a,a or a,4 (ix) jr Z,somewhere if(x) for x of type bool: bit 0,4 (ix) jr Z,somewhere Should you encounter cases where using bool increases code size please post sample code to the list or open a feature request with sample code.
