; Test conversion of floating-point values to unsigned i32s (z10 only).
;
; RUN: llc < %s -mtriple=s390x-linux-gnu -mcpu=z10 | FileCheck %s

; z10 doesn't have native support for unsigned fp-to-i32 conversions;
; they were added in z196 as the Convert to Logical family of instructions.
; Promoting to i64 doesn't generate an inexact condition for values that are
; outside the i32 range but in the i64 range, so use the default expansion.
