# RUN: llc -mtriple=aarch64-none-linux-gnu -run-pass=prologepilog %s -o - | FileCheck %s
#
# Test allocation and deallocation of SVE objects on the stack,
# as well as using a combination of scalable and non-scalable
# offsets to access the SVE on the stack.
#
# SVE objects are allocated below the (scalar) callee saves,
# and above spills/locals and the alignment gap, e.g.
#
# +-------------+
# | stack arg |
# +-------------+ <- SP before call
# | Callee Saves|
# | Frame record| (if available)
# |-------------| <- FP (if available)
# | SVE area |
# +-------------+
# |/////////////| alignment gap.
# | : |
# | Stack objs |
# | : |
# +-------------+ <- SP after call and frame-setup
