5.22 Inline functions and removal of unused out-of-line functions at link time
The linker cannot remove unused out-of-line functions from an object unless you place the
unused out-of-line functions in their own sections using one of the following methods:
• --split_sections
• #pragma arm section [section_type_list]
• linker feedback.
--feedback is typically an easier method of enabling unused function removal.
