[LLVMdev] [RFC] Extending MachineInstr.Flags

[Anton Korobeynikov]

Hello

While the use of Flags looks really easy approach I don't think it
should be used for this purpose.
You might want to check the "MachinInstr bundle" thread for discussion
on different approaches for VLIW-like MI representations.
