No, it applies to *ALL* assembler code. Also inline blocks. The only
difference is, for blocks you can hint the compiler which registers you
use, so the compiler can also tailor code which improves the interaction
with your assembler code:
This is not true for pure assembler functions tho', for performance
reasons among others.
