; Test conversion of floating-point values to unsigned i64s (z10 only).

; RUN: llc < %s -mtriple=s390x-linux-gnu -mcpu=z10 | FileCheck %s

; z10 doesn't have native support for unsigned fp-to-i64 conversions;
; they were added in z196 as the Convert to Logical family of instructions.
; Convert via signed i64s instead.

; Test f16->i64. Converted to signed as the max float value is smaller than
; the signed integer range.
