I am not too sure about that: In my opinion, your description of
the problem would be accurate if some compiler implemented asm
{}, but with a different syntax or different semantics. But GDC
simply does not (resp. will not) implement D-style inline
assembly at all. From my point of view, this is not necessarily a
problem spec-wise, as it is not guaranteed to be available – if
it was, there would be no reason to have D_InlineAsm_X86 at all.
Needless to say, inline assembly is sometimes a very convenient
feature to have, but if it is the only issue stopping GDC from
being merged to mainline GCC, I'd say the only sensible choice is
to yank it, at least it for the time being. If, at a later point,
somebody comes up with a clever way to implement it given the
constraints imposed by the GCC infrastructure, or manages to
convince the GCC maintainers to accept the »dirty« solution, it
could still be added in again.
