GDC generates invalid assembly around fiber yield operations (Not re-reading data from clobberedd memory to registers)

[Liran Zvibel via D.gnu]

I’m trying to port a 120k loc fiber based application from dmd to gdc, so applying this work around is not a good option for me (also, there are many engineers that will continue generating code…)

Thanks
