# With -Os we default to -mpreferred-stack-boundary=2, which is not
# enough for proper operation with V4SImode when the architecture
# default enables SSE. Arguably setting -mpreferred-stack-boundary=2
# under this condition is incorrect. Finding the correct set of
# options such that we don't exchange a FAIL for an XPASS is hard;
# simply force the stack boundary we need and forget about it for now.
