I think it's time for you to move to using a separate .S file instead of
inline assembly. See x86.S for an example of how this is done for bcrypt.
However, if you choose to continue with inline assembly then I think
you'll find C preprocessor's ## operator handy, to enclose variable
names, indices, etc. in double-quotes.
