; A collection of regression tests to verify the load-narrowing part of
; TargetLowering::SimplifySetCC (and/or other similar rewrites such as
; combining AND+LOAD into ZEXTLOAD).
;
; Using both arm and armv7 to show that alignment restrictions are
; considered for the narrowed load (armv7 is a bit more relaxed when it
; comes to unaligned memory accesses).

;--------------------------------------------------------------------------
; Test non byte-sized types.
;
; As long as LLVM IR isn't defining where the padding goes we can't really
; optimize these (without adding a target lowering hook that can inform
; ISel about which bits are padding).
