; This is a very contrived test case to trick the legalizer into splitting the
|
||
|
|
; v16i1 masks in the select during type legalization, and in so doing extend them
|
||
|
|
; into two v8i64 types. This lets us ensure that the lowering code can handle
|
||
|
|
; both formulations of vselect. All of this trickery is because we can't
|
||
|
|
; directly form an SDAG input to the lowering.
