[LLVMdev] Operand constraints
...nforce this restriction on the register allocator?
And the other side of the question is now to inform register allocator that
mul instruction clobbers gr7? I see some support for getting "implicit
operands" in MachineInstr.cpp, but the only method which can set them:
MachineInstr::SetRegForImplicitRef
is marked as SPARC-specific and is not documented.

[LLVMdev] Operand constraints
On my target, the multiplication can involve all general purpose registers,
but there's are still some restrictions: the first and the second operand as
well as the result must be in different registers, and neither register can
be gr7. How can I enforce this restriction on the register allocator?
