--- Comment #4 from Hongtao Liu <liuhongt at gcc dot gnu.org> ---
int sum() {
int ret = 0;
for (int i=0; i<8; ++i) ret +=(0==v[i]);
return ret;
}
int sum2() {
int ret = 0;
auto m = v==0;
for (int i=0; i<8; ++i) ret += m[i];
return ret;
}
For sum, gcc tries to reduce for an {0/1, 0/1, ...} vector, for sum2, it tries
to reduce {0/-1,0/-1,...} vector. But LLVM tries to reduce {0/1, 0/1, ... }
vector for both sum and sum2. Not sure which is correct?
