v1.9.0

Minimum bazel version: 7.0.0

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

bazel_dep(name = "toolchains_llvm", version = "1.9.0")

# Configure and register the toolchain.
llvm = use_extension("@toolchains_llvm//toolchain/extensions:llvm.bzl", "llvm")
llvm.toolchain(
   llvm_version = "16.0.0",
)

use_repo(llvm, "llvm_toolchain")
# use_repo(llvm, "llvm_toolchain_llvm") # if you depend on specific tools in scripts

register_toolchains("@llvm_toolchain//:all")

To directly use a commit from GitHub, add this block and replace commit with the commit you want.
