[LLVMdev] PBQP & register pairing
...d hook for inserting passes in that location, but it may make sense for PBQP to offer such a hook since it can support many strange constraints.

[LLVMdev] PBQP & register pairing
Hi All,
My target has some instructions requiring register pairs. I decided to give a try to the PBQP allocator : it is working fine in 99% of the cases, but I am stumbling on the following issue.
Instruction 'MPQD' takes 3 register operands inputs, with the constraint that operands 0 and 2 must be consecutive registers. Operand 1 has no particular constraint. It has no output register.
