Comment (by pdziepak):
The best solution would be to use inline assembly in C code and let GCC
take care of calling convention. Moreover, many of such asm functions
should be inlined wherever possible since they usually contain only few
instructions. Use of GCC builtins also should be considered as it would
allow some compile time optimizations, e.g. when changing byte order of
the value that is known at compile time.
