# Wrap up the aligned_alloc() tests with the different malloc libraries
# that make sense to test as this calls into their implementation of
# memalign. Currently we test libc, libumem, and libmtmalloc. mapmalloc
# is skipped because it doesn't implement memalign. libmtmalloc
# currently doesn't have an ENOMEM/EAGAIN test strategy.
