Thanks to all for the info!
(Summary for the assembler list, since the action was all on IBM-MAIN: It won't
hurt; might affect optimization slightly, but probably not worth worrying
about.)
It may have a minor effect on optimisation. Variables may now be in
storage when they were optimized into registers. But this is likely to be
less than 1% difference.
You might want to use Jump instructions rather than Branch, so you do not
have to worry about addressability

Doh, I of course meant -qasm not -dasm.

(Cross-posted to IBM-MAIN and the assembler list)
When compiling C programs with XLC, you need to specify the -dasm flag to have
inline assembler code recognized as such. I can see PoE arguments for requiring
that option; what isn't clear is whether there's any downside to it beyond the
