#
# $ clang -S -fbasic-block-sections=all llvm-symbolizer-bbsections-test.cc
# Manually reororder the sections to place them in this order:
# _Z1fi
# main.__part.4
# _Z1gi
# main
# _Z1hi
# main.__part.5
# (rest)
# Strip the .section .text directives to have all the functions in the same
# section.
# This ensures the basic blocks are reordered non-contiguous exactly like
# how a linker would do it.
