CodeVisionAVR
There are the following predefined macros:
__CODEVISIONAVR__ the version and revision of the compiler represented as an integer,
example for V2.04.0 this will be 2040
__STDC__ equals to 1
__LINE__ the current line number of the compiled file
__FILE__ the current compiled file
__TIME__ the current time in hh:mm:ss format
__UNIX_TIME__ unsigned long that represents the number of seconds elapsed since midnight
UTC of 1 January 1970, not counting leap seconds
__DATE__ the current date in mmm dd yyyy format
__BUILD__ the build number
_CHIP_ATXXXXX_ where ATXXXXX is the chip type, in uppercase letters, specified in the
Project|Configure|C Compiler|Code Generation|Chip option
_MCU_CLOCK_FREQUENCY_ the AVR clock frequency specified in the Project|Configure|C
Compiler|Code Generation|Clock option, expressed as an unsigned long integer in Hz
_MODEL_TINY_ if the program is compiled using the TINY memory model
_MODEL_SMALL_ if the program is compiled using the SMALL memory model
_MODEL_MEDIUM_ if the program is compiled using the MEDIUM memory model
_MODEL_LARGE_ if the program is compiled using the LARGE memory model
_OPTIMIZE_SIZE_ if the program is compiled with optimization for size (Project|Configure|C
Compiler|Code Generation|Optimize for: Size option or #pragma optsize+)
_OPTIMIZE_SPEED_ if the program is compiled with optimization for speed
(Project|Configure|C Compiler|Code Generation|Optimize for: Speed option or #pragma optsize)
_WARNINGS_ON_ if the warnings are enabled by the Project|Configure|C
Compiler|Messages|Enable Warnings option or #pragma warn+
_WARNINGS_OFF_ if the warnings are disabled by the Project|Configure|C
Compiler|Messages|Enable Warnings option or #pragma warn_PROMOTE_CHAR_TO_INT_ON_ if the automatic ANSI char to int type promotion is enabled by
the Project|Configure|C Compiler|Code Generation|Promote char to int option or #pragma
promotechar+
_PROMOTE_CHAR_TO_INT_OFF_ if the automatic ANSI char to int type promotion is disabled
by the Project|Configure|C Compiler|Code Generation|Promote char to int option or #pragma
promotechar_AVR8L_CORE_ signals that the program is compiled using the reduced core instruction set,
used in chips like ATtiny10. No ADIW, SBIW, LDD and STD instructions are generated in this case.
_ENHANCED_CORE_ if the program is compiled using the enhanced core instructions available
in the new ATmega chips
_IO_BITS_DEFINITIONS_ if the Project|Configure|C Compiler|Code
Generation|Preprocessor|Include I/O Registers Bits Definitions option is enbaled
_HEAP_START_ the heap starting address
_HEAP_SIZE_ the heap size specified in the Project|Configure|C Compiler|Code
Generation|Heap size option
_UNSIGNED_CHAR_ if the Project|Configure|C Compiler|Code Generation|char is unsigned
compiler option is enabled or #pragma uchar+ is used
_8BIT_ENUMS_ if the Project|Configure|C Compiler|Code Generation|8 bit enums compiler
option is enabled or #pragma 8bit_enums+ is used
_ATXMEGA_USART_ specifies which ATxmega chip USART is used by the getchar and
putchar Standard C Input/Output Functions
_ATXMEGA_SPI_ specifies which ATxmega chip SPI controller is used by the SPI Functions
_ATXMEGA_SPI_PORT_ specifies which ATxmega chip I/O port is used by the SPI controller.
The #line directive can be used to modify the predefined __LINE__ and __FILE__ macros.
The syntax is:
#line integer_constant ["file_name"]
