Hmmm... maybe I'm thinking of some older compiler, then.  Oh well.

Yup, much clearer.

It sounds like the optimization (or at least part of it) belongs in
gcc, then, but gas doesn't even have a way to manually specify compact
insns.  You'd need linker branch relaxing to get it right 100% of the
time, though, and even then it's tricky.


Patch OK.
