This mirrors the existing `//cc/compiler` package for compilers.\n\nCovered libcs: `glibc`, `musl`, `uclibc`, `bionic`, `macosx` (Apple\u0027s libSystem, using the historical value set by toolchains for all Apple platforms), `freebsd`, `netbsd`, `openbsd`, `msvcrt`, `ucrt`, `msys`, `newlib`, `picolibc`, `llvm-libc`, and `wasi-libc`. Toolchains not shipped with Bazel are encouraged to use the same canonical names.\n\nSince Bazel documents `target_libc` as \"the libc version string (e.g. `glibc-2.2.2`)\", `libc_flag` strips a version suffix (everything from the first `-` followed by a digit) before matching, so versioned values still match their family\u0027s setting while names like `wasi-libc` and `llvm-libc` are preserved.\n\nThe following changes make the new constraints usable:\n* the auto-configured Unix toolchain detects the default libc via preprocessor macros and `-dumpmachine`\n* the `target_libc` values emitted by the bundled Windows and BSD toolchain configs are changed to the correct values\n* rule-based `cc_toolchain`s can declare their `target_libc` or fall back to a reasonable default\n\nCloses #792\n\nCOPYBARA_INTEGRATE_REVIEW\u003dhttps://github.com/bazelbuild/rules_cc/pull/792 from fmeum:libc-settings 7215a9ced75b2d01816d25b87e76c8387b0eee34\nPiperOrigin-RevId: 970542238\nChange-Id: Id569a70de73fc51ca8c69ca74169b8ba44cdc1bf\n" }, { "commit": "aff544134bc9d29006f27adbe63d824dfe1436f6", "tree": "6901387e5f951a83fff05f96132dff48049ffe37", "parents": [ "e895a9562763230e961b90c658651c98a7313bcf" ], "author": { "name": "Corentin Kerisit", "email": "corentin.kerisit@gmail.com", "time": "Sat Aug 22 04:18:28 2026 -0700" }, "committer": { "name": "Copybara-Service", "email": "copybara-worker@google.com", "time": "Sat Aug 22 04:19:17 2026 -0700" }, "message": "Honor object extensions for ThinLTO merged artifacts (#853)\n\nThe ThinLTO merged object is hard-coded with an `.o` suffix even when the toolchain configures `.obj` for object files.

Since the generated module map file is declared by that very target, the name can be derived on demand from the file\u0027s owner label, which the `File` object already retains. The `name` field of the module map struct becomes optional, with `None` meaning \"named after the label of the target that generated the module map file\", and two central helpers (`get_module_map_name`, `get_module_map_label`) derive the string form and the `Label` form where needed.\n\nThis fixes the round-trip bug originally addressed in https://github.com/bazelbuild/rules_cc/pull/633, but avoids the memory regression that caused it to be rolled back in b81b6e4 (because retaining `Label` objects increased memory usage overall). Deriving the name on demand retains nothing extra as the owner label is already retained by the `File` and all name materializations are transient only (such as in `map_each` callbacks).\n\nNames are now the unambiguous canonical label string, except that main repository labels drop the leading `@@` (`//pkg:lib`), keeping the traditional module name format.
