### Built-in features
The following features are defined based on the chosen CPU and compilation options:
* `ARCH_6502` 1 if compiling for 6502, 0 otherwise
* `CPUFEATURE_65C02` 1 if compiling for 65C02-compatible processor, 0 otherwise
* `CPUFEATURE_65CE02` 1 if compiling for 65CE02-compatible processor, 0 otherwise
* `ARCH_I80` 1 if compiling for Intel 8080-like processor, 0 otherwise
* `CPUFEATURE_8080` 1 if compiling for Intel 8080-compatible processor, 0 otherwise
* `CPU_65C02`, `CPU_65CE02`, `CPU_65816`, `CPU_HUC6280`, `CPU_8080`, `CPU_GAMEBOY`, `CPU_Z80`
1 if compiling for the exact given processor, 0 otherwise
* `CPUFEATURE_GAMEBOY` 1 if compiling for Sharp LR35902-compatible processor, 0 otherwise
* `CPU_6502` 1 if compiling for any pre-65C02 6502-like processor, 0 otherwise
* `CPUFEATURE_Z80` 1 if compiling for Z80-compatible processor, 0 otherwise
* `CPUFEATURE_DECIMAL_MODE` 1 if decimal mode is enabled, 0 otherwise
* `CPUFEATURE_65C02`, `CPUFEATURE_65CE02`, `CPUFEATURE_HUC6280`, `CPUFEATURE_65816_EMULATION`, `CPUFEATURE_65816_NATIVE`,
`CPUFEATURE_8080`, `CPUFEATURE_GAMEBOY`, `CPUFEATURE_Z80`,
`CPUFEATURE_6502_ILLEGALS`, `CPUFEATURE_Z80_ILLEGALS` 1 if given instruction subset is enabled, 0 otherwise
* `OPTIMIZE_FOR_SIZE`, `OPTIMIZE_FOR_SPEED`, `OPTIMIZE_INLINE`, `OPTIMIZE_IPO`
1 if given optimization setting is enabled, 0 otherwise
* `SYNTAX_INTEL`, `SYNTAX_ZILOG` 1 if given assembly syntax is chosen, 0 otherwise; doesn't take this file's pragmas into account
* `USES_ZPREG` 1 if the zeropage pseudoregister is used, 0 otherwise
* `ZPREG_SIZE` size of the pseudoregister in bytes
* `USES_IX_STACK`, `USES_IY_STACK` 1 if given index register is used as a base pointer for stack-allocated variables, 0 otherwise
* `USES_SHADOW_REGISTERS` 1 if interrupts preserve old registers in the shadow registers, 0 otherwise
### Commonly used features
@ -52,12 +68,18 @@ You can also define feature values using the `-D` command line option.
* `CBM_64` 1 if the target is an 8-bit Commodore computer compatible with Commodore 64, 0 otherwise
* `CBM_264` 1 if the target is an 8-bit Commodore computer from the 264 line, 0 otherwise
* `KEYBOARD` 1 if the target has a keyboard, 0 otherwise
* `JOYSTICKS` the maximum number of joysticks using standard hardware configurations, may be 0
* `HAS_BITMAP_MODE` 1 if the target has a display mode with every pixel addressable, 0 otherwise
* `MOS_6510` 1 if the target uses a MOS 6510-compatible processor (with an I/O port at $0000/$0001)
* `CPM` 1 if the target is CP/M, 0 otherwise
### Built-in preprocessor functions and operators
The `defined` function returns 1 if the feature is defined, 0 otherwise.
