/*
What are those keeper functions?
The problem: gcc doesn't know that the assembler routines call
static functions so gcc may not emit the definition (i.e., the
code) for these functions. In gcc 3.1 and up
"__attribute__ ((used))" exists and solves the problem.
For older gcc versions it's not so easy. One could use the
-fkeep-inline-functions but that keeps a surprising number of
functions which bloats the compiled library. It seems otherwise
harmless, though. Alternatively, one could use
-fno-inline-functions which works right now but might cause a
slowdown under some circumstances. The problem with these methods
is that they do not automatically adapt to the compiler used.
The best solution seems to be to create dummy functions that
reference the appropriate static functions. It's then necessary
to "use" these functions in a way that gcc will not optimize
away. The keeper functions use assembly code to confuse gcc.
One drawback is that the keeper functions are externally visible
so they shouldn't do anything harmful.
With the right linker, one could make the keeper functions local
so they wouldn't be visible.
