Please see https://godbolt.org/z/K6bM5qfx3 and compare the gcc and clang output
The compiler is able to calculate the `pow` results at compile time, however it still issues a __cxa_guard_acquire/__cxa_guard_release pair just to move those values around in memory. Meanwhile, gcc is able to use the .rodata section directly.
