Comment (by simonmar):
Interesting. Geoff's accidental change to the calling convention
''almost'' worked, it was just the generic apply functions that were still
using the old convention because that code has its own implementation of
the calling conventions (`utils/genapply`). So that's why reproducing the
bug relied on not inlining something, thus using the generic apply code.
The reference to `D1` is correct, because that's part of the ''return''
convention, which always uses `D1` regardless of whether it's a real
register or not.
