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'.

Named Registers are named metadata pointing to the register name which will be read from/written to as an argument to the intrinsic @llvm.read/write_register.
So far, only the name is being passed down, but other options such as register type, allocation type or even optimization options could be passed down via the metadata node.
