Why shouldn't it turn off -mxsave? -mavx sets -mxsave too. I mean, otherwise if one does say on -m32 do -mavx -mno-avx, then won't that turn on -mxsave and not turn it off again? Or with target pragmas. I believe we generally want consistency, if option ABC turns automatically option DEF, then turning off option DEF explicitly disables option ABC.
