9.51 attribute((weak)) function attribute

Functions defined with __attribute__((weak)) export their symbols weakly.

Functions declared with __attribute__((weak)) and then defined without __attribute__((weak)) behave as weak functions. This is not the same behavior as the __weak keyword.

Note

This function attribute is a GNU compiler extension that the ARM compiler supports.

Examples

extern int Function_Attributes_weak_0 (int b) __attribute__((weak));
