fc2512cfb727d49529d8ed99164db871f4829b73Robert Mustacchi * Basic tests for aligned_alloc(3C). Note that we test ENOMEM failure by
fc2512cfb727d49529d8ed99164db871f4829b73Robert Mustacchi * relying on the implementation of the current libc malloc. Specifically we go
fc2512cfb727d49529d8ed99164db871f4829b73Robert Mustacchi * through and add a mapping so we can't expand the heap and then use it up. If
fc2512cfb727d49529d8ed99164db871f4829b73Robert Mustacchi * the memory allocator is ever changed, this test will start failing, at which
fc2512cfb727d49529d8ed99164db871f4829b73Robert Mustacchi * point, it may not be worth the cost of keeping it around.
fc2512cfb727d49529d8ed99164db871f4829b73Robert Mustacchi * Alignment must be sizeof (void *) (word) aligned.
