; This test checks that the cost of a splat-load shuffle is correctly detected
|
||||
; as 0, because the combined load + broadcast is lowered to a `ld1r` instruction.
|
||||
;
|
||||
; NOTE: The code in this test is a hack. Since TTI cannot currently detect a
|
||||
; proper broadcast pattern from a scalar load (like the one that follows),
|
||||
; we use a vector load as the shuffle's operand to trigger the pattern.
