This patch fixes the search for function like __mcount() or gprof_start().
The issue existed for functions with function attribute (__attribute__()): Doxygen didn't parsed it properly. It fixes such warnings:
warning: documented symbol '__mcount' was not declared or defined.
After changing Doxygen configuration to fix it, new warnings appears. For example:
warning: explicit link request to 'PSP_VAUDIO_FORMAT_' could not be resolved
It's fixed by using the full name of the constants. By the way, it also fixes the link to the constants in the documentation.
