# Expected results:
#
# Due to the Mappings section, all six of these library directories should
# match the command-line flag --target=thumbv7em-none-unknown-eabi.
#
# The two "non_exclusive" directories, which don't have an ExclusiveGroup at
# all, should both be selected. So should the two "own_group", each of which
# specifies a different value of ExclusiveGroup. But the three "exclusive",
# which have the _same_ ExclusiveGroup value, should not: the third one wins.
# So we expect five of these seven directories to show up in the clang-cc1
# command line, but not testdir1_exclusive or testdir2_exclusive.
