Enum SymbolBinding 

pub enum SymbolBinding {
    Local = 0,
    Global = 1,
    Weak = 2,
}

Symbol binding — the container-independent enum from synth_core, shared with the aarch64 object plan since #1180 (one definition of LOCAL/GLOBAL, one locals_first rule). Re-exported so every synth_backend::elf_builder::SymbolBinding path keeps working unchanged. Symbol BINDING — whether a symbol takes part in cross-object resolution (#656 ARM, #1180 / RQ-65-FUNCN aarch64).

This is a CONTAINER-INDEPENDENT concept, which is why it lives here and not in a writer: ELF spells it STB_LOCAL / STB_GLOBAL / STB_WEAK in st_info’s high nibble (the discriminants below are exactly those values), Mach-O spells Local as N_EXT CLEAR and Global as N_EXT SET on the nlist_64. The decision that a synth-invented name — a func_N call label, __synth_globals, __synth_func_table — is Local while a wasm export or import is Global is made ONCE, at the object PLAN, and every container reads it from there. Two independently compiled synth objects both define func_1; a Global binding made linking them into one program a duplicate symbol refusal, in every container (measured on ELF ld.lld and Mach-O Apple ld, #1180).

Variants

Local = 0

File-local: resolves relocations within its own object (they bind by symbol INDEX, not by name) and is invisible to every other object.

Global = 1

Visible to the link: the name an embedder calls, or the import it defines.

Weak = 2

Weak (ELF STB_WEAK); no synth writer emits it today.
