Bumps toolchains_llvm from 1.12.0 to 1.13.0.

Release notes

Sourced from toolchains_llvm's releases.

v1.13.0

Minimum bazel version: 7.0.0

See the changelog for changes in this release. In 1.13.0, first / latest prerelease selection requires llvm_version_allow_prereleases = True, or linker_version_allow_prereleases = True for catalogued linkers. Exact pins are unchanged. Read the 1.13.0 migration guide for configuration changes, range choices, and SemVer RC ordering.

If you're using bzlmod, add the following to MODULE.bazel:

bazel_dep(name = "toolchains_llvm", version = "1.13.0")
Configure and register the toolchain.
llvm = use_extension("@​toolchains_llvm//toolchain/extensions:llvm.bzl", "llvm")
llvm.toolchain(
llvm_version = "23.1.5",
)
use_repo(llvm, "llvm_toolchain")
use_repo(llvm, "llvm_toolchain_llvm") # if you depend on specific tools in scripts
register_toolchains("@​llvm_toolchain//:all")

These examples use the linker bundled with LLVM 23.1.5; its macOS linker does not require the LLVM 23.1.0–23.1.2 SDK/TAPI workaround. LLVM 23.1.5 has no macOS x86_64 archive; Intel Mac users must select another available LLVM version through llvm_version or llvm_versions.

1.13.0

Migration required for prerelease selectors

• first / latest prerelease selection now requires an explicit opt-in; specifying an RC in a requirement no longer suffices. Exact pins are unchanged. See the 1.13.0 migration guide for the required flags, range choices, and changed RC ordering under SemVer.

Version selection

• Shared expression-based LLVM and linker version selectors, including major, minor, and patch constants, function expressions, wildcards, and compatible-release comparisons. Candidates must have an artifact for the execution platform before version selection.
• Environment-derived linker versions through getenv(NAME,fallback), matching LLVM version selection.
• Independent prerelease policies in feature overrides; linker-only policy changes can reuse the base LLVM archive.

LLVM distributions

• Add checksum-pinned LLVM 23.1.5 archives for Linux ARM64/x86_64, macOS ARM64, and Windows ARM64/x86_64. Both xz and zstd metadata are retained; automatic selection continues to use xz. Existing LLVM and mold entries are preserved.

Dependencies and publishing

• WORKSPACE dependencies: rules_cc 0.2.27, apple_support 2.11.0, and bazel_features 1.54.1.
• Test dependencies, including rules_python 2.4.6, rules_go 0.65.0, rules_foreign_cc 0.17.0, rules_rust 0.75.0, BoringSSL 0.20261020.0, and WORKSPACE aspect_bazel_lib 3.8.0.
• BCR publishing workflow to publish-to-bcr 1.6.0.
