  "message": "Pass fission flags to ThinLTO backend actions (#837)\n\nFix interaction between `--fission` and `--features\u003dthin_lto`. Without this, every LTO backend action fails:\n\n```\nERROR: output \u0027prog.lto/bazel-out/k8-opt/bin/_objs/prog/a.dwo\u0027 was not created\nERROR: LTO Backend Compile prog.lto/bazel-out/k8-opt/bin/_objs/prog/a.o failed:\n       not all outputs were created or valid\n```\n\nFixed by adding `ACTION_NAMES.lto_backend` to the `per_object_debug_info` flag_set in\n`cc/private/toolchain/unix_cc_toolchain_config.bzl` and `cc/private/toolchain_config/legacy_features.bzl`.\n\nAdds a test that uses the real Linux `cc_toolchain_config` since that wasn\u0027t covered by the existing test, and was broken.\n\nCloses #837\n\nCOPYBARA_INTEGRATE_REVIEW\u003dhttps://github.com/bazelbuild/rules_cc/pull/837 from akonradi:abakon/fission-flags-for-lto-backend c033aba8813345a9c84a3f48cf11fb9bf970774d\nPiperOrigin-RevId: 964562193\nChange-Id: I09f0c92967f5d148dfa24edca0533e306a2647bb\n",
