; Verify that scalar integer conversions to FP compile successfully
; (at one time long double failed with avx512f), and that reasonable
; instruction sequences are selected based on subtarget features.
; Due to the plethora of reasonable sequences we just check for
; one key instruction, usually a cvt or fild, allowing the test
; to be relatively easily updated when sequences are improved.
