> tests crashes or make tnameserv crash
> Problem: Current implementation of superword optimization does not
> check for unsafe memory accesses. Since
> unsafe memory accesses could not be aligned appropriately without
> runtime checking, a un-aligned superword
> read/write could cause runtime failure.
> Solution: Simply disable superword for unsafe memory access whose base
> is top.
> Tests: Test case in 6852078
