Overview

A file-scope (global) variable declaration. type is the declared Rubycc::Type (int, char, a pointer, a one-dimensional array or a struct/union). At most one of two initializer fields is set: initializer_value is a plain scalar-integer initializer folded to a Ruby Integer on the spot (the common "int g = 1 + 2;" case, kept folded so nothing downstream re-evaluates it), while initializer_node carries a still-unfolded initializer the generator lowers itself — a brace initializer-list (AST::InitializerList) for an aggregate or scalar, a string literal for a char array, or an address constant for a pointer (a null pointer, "&other_global", a decayed global array name or a string literal). Both are nil for an uninitialized global, which lands in .bss. const and storage carry the same top-level const flag and storage-class specifier (nil/:static/:extern) as VariableDecl; the generator diagnoses writes against a const global but does not yet act on the storage class (Phase B). alignas carries the same _Alignas boundary VariableDecl does.
