; 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.
