GCC11's behavior:
/opt/at15.0/bin//gcc test.c -mvsx -mcpu=power7
test.c: In function ‘test3’:
test.c:7:5: note: builtin ‘__builtin_vec_neg’ requires builtin
‘__builtin_altivec_neg_v2di’
7 | return vec_neg (x);
| ^~~~~~
In file included from test.c:2:
test.c:7:12: error: ‘__builtin_altivec_neg_v2di’ requires the ‘-mpower8-vector’
option
