# Test normal conditional branches in cases where block alignments cause
# some branches to be out of range.
# RUN: python %s | llc -mtriple=s390x-linux-gnu -align-all-blocks=8 | FileCheck %s
# Construct:
#
# b0:
# conditional branch to end
# ...
# b<N>:
# conditional branch to end
# b<N+1>:
# conditional branch to b0
# ...
# b<2*N>:
# conditional branch to b0
# end:
#
# with N == 256 + 4. The -align-all-blocks=8 option ensures that all blocks
# are 256 bytes in size. The first 4 blocks and the last 4 blocks are then
# out of range.
