At least when building with recent LLVM trunk (towards LLVM 22) on macOS 15.6 (24G84) against Xcode 16.4 (16F6):
```
$ cat test.cc
#include <complex>
#include <iostream>
std::complex<double> div(std::complex<double> a, std::complex<double> b) {
return a / b;
}
int main() {
std::cout << div({1, 2}, {3, 4}) << '\n';
}
```
```
$ ~/llvm/inst/bin/clang++ -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX15.5.sdk test.cc
Undefined symbols for architecture arm64:
"___divdc3", referenced from:
std::__1::complex<double> std::__1::operator/[abi:de220000]<double, 0>(std::__1::complex<double> const&, std::__1::complex<double> const&) in test-c3cfce.o
ld: symbol(s) not found for architecture arm64
clang++: error: linker command failed with exit code 1 (use -v to see invocation)
```
