For ARM target platform while using, ARM compiler, Use the following compiler directive around the target function to suppress "Warning[Pe177]: function declared but never referenced" warning messages:

#pragma diag_suppress=Pe177
void foo(void)
{
/* does something but is not being called for the current build */
}
