compiled with clang20 failed while clang18 passed for using a vector with runtime size #2137
Description
Here is the code,
double dprod(const std::vector& v) {
double r = 1;
for (int i = 0; i < v.size(); i++) {
r *= v[i];
}
return r;
}
double g2(double x, int n) {
std::vector v;
for (int i = 0; i < n; ++i) {
v.push_back(std::pow(x, i));
}
return dprod(v);
}
int main() {
double x = 3;
int n = 5;
double dg2_dx = __enzyme_autodiff((void*)g2, enzyme_out, x, enzyme_const, n);
printf("g2(%g, %d)=%g, dg2_dx=%g\n", x, n, g2(x,n), dg2_dx);
}
It works fine when built with clang18 with "-O3 -std=c++20", but it failed with clang20 with the same build/compilation options, here is the error message,
unknown tbaa call instruction user inst: %call.i = tail call noundef double @pow(double noundef %x, double noundef %conv.i) #12, !dbg !2031, !tbaa !2032 vdptr: {[]:Pointer, [-1]:Integer}
