[LLVMdev] LSR pass

[Richard Osborne]

LSR queries TargetLowering::isLegalAddressingMode() to find out if a 
particular addressing mode is legal:

/// isLegalAddressingMode - Return true if the addressing mode 
represented by
/// AM is legal for this target, for a load/store of the specified type.
/// The type may be VoidTy, in which case only return true if the addressing
/// mode is legal for a load/store of any legal type.

You'll need to implement this hook in your target.
