This looks like a good suggestion to me. These warnings should be
enabled/disabled with -W{no-}psabi, since they in fact are psABI warnings.
The patch could be as simple as adding OPT_Wpsabi as the first argument to:
warning (0, "AVX vector return without AVX enabled changes the ABI");
-Wpsabi is enabled by default, so there would be no user-visible default
changes.
HJ, what is your opinion?
