# These options are called "multilib_flags" within the gcc test suite. Most
# architectures handle these options in a sensible way such that tests that
# are incompatible with the provided multilib are marked as UNSUPPORTED.
#
# Note: multilib flags are added to the compile command after the args
# provided by any test (through dg-options), CFLAGS_FOR_TARGET is always
# added to the compile command before any other args but is not interpted
# as options like multilib flags.
#
# i686, x86-64 and aarch64 are special, since most toolchains built for
# these targets don't do multilib the tests do not get correctly marked as
# UNSUPPORTED. More importantly the test suite itself does not handle
# overriding the multilib flags where it could (like other archs do). As
# such do not pass the target compiler args for these targets.
