[LLVMdev] [PATCH] Split LoopUnroll pass into mechanism and policy

[Matthijs Kooijman]

Hi All,

new patch is attached. There was a small logic error, which is now fixed by
making getSmallConstantTripMultiple return 1 when it doesn't have any useful
result (instead of 0). Makes more sense, since the trip count is always a
multiple of 1 :-)

This only leaves one failing test case (test/CodeGen/X86/vec_set-5.ll), but I
don't think it's related to this patch.

Gr.
