Enumeration Type Documentation

ConstantEmissionKind

enum ConstantEmissionKind

Can we constant-emit a load of a reference to a variable of the given type?

This is different from predicates like Decl::mightBeUsableInConstantExpressions because we do want it to apply in situations that don't necessarily satisfy the language's rules for this (e.g. C++'s ODR-use rules). For example, we want to able to do this with const float variables even if those variables aren't marked 'constexpr'.
