  "message": "feat(go): add directives to set Go/C compiler and linker flags on generated rules (#2372)\n\nImplements #2371.\n\nAdds a family of Go directives that set string-list compiler/linker\nattributes on generated rules. The main motivation is applying flags to\nexternal dependencies generated by `go_deps`, which have no hand-written\nbuild files to edit — the directives flow through the existing\n`directives` channel of `go_deps.gazelle_default_attributes` /\n`gazelle_override`.\n\n| Directive | Attribute | Applied to | Gate |\n|---|---|---|---|\n| `# gazelle:go_gc_goopts` | `gc_goopts` | `go_library` / `go_binary` /\n`go_test` with sources | — |\n| `# gazelle:go_gc_linkopts` | `gc_linkopts` | `go_binary`, `go_test` |\n— |\n| `# gazelle:go_copts` | `copts` | cgo targets (`go_library`) | `cgo \u003d\nTrue` |\n| `# gazelle:go_cppopts` | `cppopts` | cgo targets (`go_library`) | `cgo\n\u003d True` |\n| `# gazelle:go_cxxopts` | `cxxopts` | cgo targets (`go_library`) | `cgo\n\u003d True` |\n| `# gazelle:go_clinkopts` | `clinkopts` | cgo targets (`go_library`) |\n`cgo \u003d True` |\n\n**Notes on design (per discussion in the issue):**\n- The C flags (`copts`/`cppopts`/`cxxopts`/`clinkopts`) are **merged**\nwith the flags Gazelle derives from `#cgo` comments, not overwritten.\n- `clinkopts` is set on `go_library`, matching where the source-derived\n`clinkopts` already go. Gazelle never generates a cgo\n`go_binary`/`go_test` (cgo isn\u0027t allowed in `_test.go`, and a cgo `main`\nbecomes a cgo `go_library` embedded by a plain `go_binary`), so in\npractice all C flags land on `go_library`.\n- `gc_goopts`/`gc_linkopts` are set directly (not derived from source);\n`gc_goopts` needs sources to compile, `gc_linkopts` applies to the\nlinking rules.\n- Values may be separated by whitespace and/or commas (`-N -l` is\nequivalent to `-N,-l`); an empty value resets the directive.\n\n**Tests**\n- Unit tests for directive parsing, reset, and inheritance\n(`config_test.go`).\n- A generate golden (`testdata/compiler_flags`) exercising emission, the\ncgo gate, the library-vs-linking gate, and merging with `#cgo`-derived\nflags.\n- `go test ./language/go/` passes; new/changed files are `gofmt`-clean.\n\n**Docs**\n- `language/go/reference.md` documents all six directives.\n\n*Drafted with Claude Code.*\n\n---------\n\nCo-authored-by: Claude Opus 4.8 \u003cnoreply@anthropic.com\u003e\nCo-authored-by: Jay Conrod \u003cjay@engflow.com\u003e",
