Am I the only one thinking this is a compiler bug, rather than correct
behaviour?

The macro definition is not an assembly block as such, but rather just
that: a macro definition which is supposed to be evaluated at compile
(or assemble) time.  To reorder it on the source level seems completely
out of the scope of LTO.

Am I missing something or should this be fixed in GCC?
