--- Comment #4 from Elliott M <ehem+gccbugs at m5p dot com> ---
I had guessed this was exposing internals, I had hopes those were the internals
from a score of years ago and could readily be resolved now.
This is valuable for interfacing with things which have calling conventions
distinct enough not to work with pure-C, but similar enough to only need 1-2
assembly instructions. Notably avoiding lvalues is valuable for things which
could otherwise fit into macros.
Jakub Jelinek, your example fails, `dummy` is an lvalue. Notably if this is
part of a `#define SOME_MACRO(foo)`, then `SOME_MACRO(dummy)` won't work.
