Considering all possible features are known by the linker during compile-time, we can create arrays on the stack instead of dynamically allocating hash maps. We use a simple bitset to determine whether a feature is enabled or not, and from which object file it originates. This allows us to make feature validation slightly faster and use less runtime memory. In the future this could be enhanced further by having a single array instead with a more sophisticated bitset.
