[llvm-dev] IsDead, IsKill

[Quentin Colombet via llvm-dev]

Hi Carl,

Look at the comments in include/llvm/CodeGen/MachineOperand.h for the documentation of the various flags.

IsDead means that a definition is never used.
IsKill means that this is the last use of a given register.

Cheers,
-Quentin
