[llvm-commits] [PATCH] Execution domain support for VMOV and VLDR

Hi Anton,

Hmm. The conversion does feel particularly error-prone. I think the
transformations are probably too dissimilar to automate though, even
within a single target. We could almost certainly improve things so
that a BuildMI is used to make a fresh instruction in all cases. We
might be able to move the implicit operand transfer into generic code,
but that almost feels more fragile to me: it's just asking for a case
to slip through where the default behaviour is unacceptable but
because it's hidden away no-one realises.

What did you have in mind?

Tim.
