rnk added a comment. This isn't sufficient, GlobalDCE will remove the internal constant. It's also unlikely that the constant will survive `--gc-sections / -fdata-sections`. A better solution would be to add a new attribute (`__attribute__((nondiscardable))`? too close to `nodiscard`?) that adds the global in question to `@llvm.used` and excludes it from -fdata-sections.
