None of these macro names can be the subject of a #define or a #undef preprocessing
directive. The values of these predefined macros (except for __LINE__ and __FILE__ )
remain constant throughout the translation unit.
The following additional macros are predefined by the Z8 Encore! C-Compiler:
All predefined macro names begin with two underscores and end with two underscores.
The following sections describe predefined macros:
•
Examples – see page 214
__TIME__ This macro expands to the compilation
time in the format “hh:mm:ss” (a string
literal).
__UNSIGNED_CHARS__ Defined if the type char is equivalent to the
type unsigned char.
__CONST_IN_RAM__ This macro is defined if the –const=ram command line
compilation option is used.
__CONST_IN_ROM__ This macro is defined if the –const=rom command line
compilation option is used.
__ENCORE__ This macro is defined and set to 1 for the Z8 Encore! compiler
and is otherwise undefined.
__EZ8__ This macro is defined and set to 1 for the Z8 Encore! compiler
and is otherwise undefined.
__FPLIB__ This macro is defined on all Zilog compilers and indicates
whether the floating-point library is available. If the floating-
point library is available, the macro expands to 1; otherwise, it
expands to 0.
__MODEL__ This macro indicates the memory model used by the compiler
as follows:
0Small model
3Large model
__ZDATE__ This macro expands to the build date of the compiler in the
format YYYYMMDD. For example, if the compiler were built on
May 31, 2006, then __ZDATE__ expands to 20060531. This
macro gives a means to test for a particular Zilog release or to
test that you are using a version of the compiler that was
released after a particular new feature has been added.
__ZILOG__ This macro is defined and set to 1 on all Zilog compilers to
indicate that the compiler is provided by Zilog.
