what do all those __attribute__(()) mean?
I have been looking into the document of gcc, and did not find any thing of using __attribute__ as follows
__attribute__((safe))
__attribute__((bitwise))
__attribute__((force))
i actually find those above when i read kernel source code. And i just can not figure them out with gcc manual.
what are the meanings ?
or it is kind of usage of __attribute__ with any word that just to keep a note or what?
thank you first
