; 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 f32->i64.

; CHECK-LABEL: f1:
; CHECK: cebr
; CHECK: sebr
; CHECK: cgebr
; CHECK: xihf
; CHECK: br %r14
  %conv = fptoui float %f to i64
  ret i64 %conv
}

; Test f64->i64.

; CHECK-LABEL: f2:
; CHECK: cdbr
; CHECK: sdbr

  ret i64 %conv
}

; Test f128->i64.
