# This test is used to acknowledge situation when spill register is killed
# in instruction after the spill occurs.
# Generated MIR is changed in order to test case when instruction after
# possible spill, say instruction B, kills register different than than
# the one that is used in possible spill, say instruction A. In that case
# the instruction A is not recognized as spill. Changed instructions are
# commented in MIR below.
#
# ...
# A - possible spill instruction with register R2
# B - instruction that kills R3
