; This test used to test vector spilling using vstmia/vldmia instructions, but
; the changes for PR:18825 prevent that spilling.

; VST1 and VLD1 are now used for spilling/restoring.
;
; TODO:
; I think more vldm should be generated, initial ones are used to load some
; elements and then a sequence of vldr are used:
; vldr  d15, [r1, #104]
; vldr  d13, [r2, #96]
; vldr  d9, [r1, #120]
; vldr  d11, [r2, #112]
; vldr  d14, [r1, #96]
; vldr  d12, [r2, #88]
; vldr  d8, [r1, #112]
; vldr  d10, [r2, #104]

; Also this patterns repeats several times which certainly seems like a vld1.64
; should be used to load the data:
; vldr  d16, [r1, #16]
; vldr  d17, [r1, #24]
; vst1.64 {d16, d17}, [lr:128]    @ 16-byte Spill
