Overview

Package plan9 scans Plan 9 assembly (Go's asm dialect) source for TEXT and GLOBL symbol definitions.

Plan 9 asm has no viable tree-sitter grammar: existing asm grammars target GAS/NASM, while Plan 9 uses TEXT ·name(SB), pseudo-registers (SB/FP/SP/PC) and the middle dot. We only need symbol definitions, so a line scanner is more robust and dependency-free.

This package is intentionally dependency-free (no graph/index/resolve imports): both internal/index (AsmParser, same-language nodes) and internal/resolve (Plan9AsmResolver, the Go<->asm EAsm edge) need this scanner, and internal/index already imports internal/resolve — a shared leaf package is the only way to give both sides the scanner without an import cycle.
