--- Comment #4 from Eric Botcazou <ebotcazou at gcc dot gnu.org> --- > I don't understand the comment "questionable optimization patterns". I don't see much value in optimizing a memcpy to initialize a variable, it's unlikely to be in a hot spot. I'd suggest adding 'const' to the testcase. > Optimizing for size should be controlled by -Os. It's just classical constant pool technique though and constant pools are not conditionalized on -Os in the compiler.
