Yes, but please also add:

Hi,
So, something like the patch attached?
* config/i386/i386.c (ix86_option_override_internal): Turn
on all -mavx target flags by default as they are dependent
on AVX anyway.
Thanks

Actually -mred-zone seems right, but stuff like -msseregp

Hi,
Inlining sse* functions into avx is broken? Here is an example:
__attribute__((always_inline,target("sse3")))
inline int callee ()
{
return 0;
}
__attribute__((target("avx")))
inline int caller ()
{
return callee ();
}
main ()
{
return caller ();
}
$ g++ -O2 foo.cc
error: inlining f
