I for one consider this a much more graceful approach. ASM is a
standard language, albeit cpu-specific. Apple's and GCC's hacks and
extensions on top of the C language are proprietary, incompatible, and
lock users into GCC in the long term or else force other compilers
that might compete to duplicate the same disgusting hacks.
Also, with GCC's notoriously bad code generation, hand-coded asm loops
will probably be measurably faster too.
