I noticed that gcc (at least on the i386) does not open code many of
quad_t operations, thus requiring function calls to perform those
Would there be any benifit in the kernel code for adding patterns to
gcc so it could open code those operations? ie. are there any loops
or other frequently executed code that uses quad_t's?
I could probably profile the kernel and figure this out by myself, but
I'd rather not if I don't have to.
