That's not an appropriate change to the test; it's clear that test is deliberately about testing what happens with -funsafe-math-optimizations. Rather, any particular new pieces that won't work with -funsafe-math-optimizations should have #ifdef UNSAFE conditionals in tg-tests.h, like the existing conditionals there. -- Joseph S.
