--- Comment #23 from nightstrike <nightstrike at gmail dot com> ---
Given that Comment #1 clearly shows g++ 4.8 working, I think this should
qualify as a regression. Moreover, g++ 6.2 works correctly, so this was fixed
at some point between 4.9 and 6.2:
$ cat > a.cc
void f() {
int i __attribute__((vector_size(2*sizeof(int))))={2,3};
__builtin_shuffle(i,i);
}
$ g++ -c a.cc -Wunused-value
a.cc: In function 'void f()':
a.cc:3:3: warning: value computed is not used [-Wunused-value]
__builtin_shuffle(i,i);
^~~~~~~~~~~~~~~~~
