; This file provides a simple sanity check of float and double operations for
; RV32I and RV64I. This is primarily intended to ensure that custom
; legalisation or DAG combines aren't incorrectly triggered when the F
; extension isn't enabled.

; TODO: f32 parameters on RV64 with a soft-float ABI are anyext.
