The following GCC function attributes are supported:
The following additional TI-specific function attribute is supported:
For example, this function declaration uses the alias attribute to make "my_alias" a function alias for the "myFunc" function:
void my_alias() __attribute__((alias("myFunc")));
The format attribute is applied to the declarations of printf, fprintf, sprintf, snprintf, vprintf, vfprintf, vsprintf, vsnprintf, scanf, fscanf, vfscanf, vscanf, vsscanf, and sscanf in stdio.h. Thus when GCC extensions are enabled, the data arguments of these functions are type checked against the format specifiers in the format string argument and warnings are issued when there is a mismatch. These warnings can be suppressed in the usual ways if they are not desired.
See Section 7.9.21 for more about using the interrupt function attribute.
The malloc attribute is applied to the declarations of malloc, calloc, realloc and memalign in stdlib.h.
The retain attribute has the same effect as the RETAIN pragma (Section 7.9.31). That is, the section that contains the function will not be omitted from conditionally linked output even if it is not referenced elsewhere in the application.
