-# Test normal conditional branches in cases where the sheer number of
-# instructions causes some branches to be out of range.
-# RUN: python %s | llc -mtriple=s390x-linux-gnu | FileCheck %s

-# Construct:
-#
-# before0:
-# conditional branch to after0
-# ...
-# beforeN:
-# conditional branch to after0
-# main:
-# 0xffd8 bytes, from MVIY instructions
-# conditional branch to main
-# after0:
-# ...
-# conditional branch to main
-# afterN:
-#
-# Each conditional branch sequence occupies 8 bytes if it uses a short branch
-# and 10 if it uses a long one. The ones before "main:" have to take the branch
-# length into account -- which is 4 bytes for short branches -- so the final
-# (0x28 - 4) / 8 == 4 blocks can use short branches. The ones after "main:"
-# do not, so the first 0x28 / 8 == 5 can use short branches. However,
-# the conservative algorithm we use makes one branch unnecessarily long
-# on each side.
