# need to turn it off for mangling to work. The test is currently a

# -fwrapv is needed for gcc to emit well-behaved code in the presence of
# integer wrap around. (Trac #952)
#
# -fno-unit-at-a-time or -fno-toplevel-reoder is necessary to avoid gcc
# reordering things in the module and confusing the manger and/or splitter.
