GCC doesn't have constraints for registers %r8 .. %15. As D

r10 in the instruction string.

Thank you! This will do the trick! Do you happen to know if D
plans to add "registers" in the future or if it has been
suggested but was rejected?
Also, how can I see the D specific options for GDC? Thinks like
how to set "versions", options like the "-fno-druntime" and other
specific D stuff as I'll I'm seeing in the "--help" message are
options that are general and the output is in general the same as
GCC.
