Robert's point is a good one. Aviod inline assembler where possible. I've
often found that GCC's optimization was better than I would've come up with
anyway. I've only used inline assembly in a few cases where I needed the
absolute best performance, which involved using instructions that it was
hard to get GCC to emit. It seems that you're using a pseudo-opcode that
might not even be recognized by the GCC compiler. Regarding inline assembly
syntax in general, it seems that you're missing some syntax concepts that
can be found here:

http://www.ibiblio.org/gferg/ldp/GCC-Inline-Assembly-HOWTO.html#s2

Then, if you really need to get in deep you can check out your GCC version's
manual section entitled "Constraints for asm operands", which will also have
target-specific bits. But again, as recommended by Robert, stay away from
inline assembly, unless absolutely
necessary.<http://gcc.gnu.org/onlinedocs/gcc-4.0.1/gcc/Constraints.html#Constraints>
