; RUN: llc -verify-machineinstrs -mtriple=aarch64-none-linux-gnu -disable-post-ra --frame-pointer=all < %s | FileCheck %s

; The purpose of this test is to verify that frame pointer (x29)
; is correctly setup in the presence of callee-saved floating
; point registers.  The frame pointer should point to the frame
; record, which is located 16 bytes above the end of the CSR
; space when a single FP CSR is in use.
