; TODO: we can't pass half-precision arguments as "half" types yet. We do
|
||
|
|
; that for the time being by passing "float %f.coerce" and the necessary
|
||
|
|
; bitconverts/truncates. In these tests we pass i16 and use 1 bitconvert, which
|
||
|
|
; is the shortest way to get a half type. But when we can pass half types, we
|
||
|
|
; want to use that here.
