Predefined macros

The compiler preprocessor has predefined macros (some refer to these as predefined

symbols). The compiler simulates variable definitions that describe the compile-time

environment and properties of the target processor.

This chapter lists the predefined macros that all eTPU build tools compilers make available.

__COUNTER__

Preprocessor macro that expands to an integer.

Syntax

__COUNTER__

Remarks

The compiler defines this macro as an integer that has an initial value of 0 incrementing by 1

every time the macro is used in the translation unit.

The value of this macro is stored in a precompiled header and is restored when the

precompiled header is used by a translation unit.

15.2

__cplusplus

Preprocessor macro defined if compiling C++ source code.

__cplusplus
