No, the "=" means that. Well to be precise, it means GCC should copy
the output of the asm code into `size' if it needs it.
According to the GCC documentation... "&" means it's an earlyclobber
register, meaning it can be clobbered before all the inputs have been
consumed.
Personally I would have declared "ecx" in the list of clobbered
registers and not had any output operands at all. Conceptually, the
code doesn't output anything. Does that work, or are there
GCCisms/EGCSisms I don't know about?
