Any way to suppress Clang warnings? ("argument unused during compilation")

[vittorioromeo]

Hello, I am using hedron_compile_commands in a fairly large Bazel project that uses Clang as the main compiler. While it works, it spews a lot of warnings/errors, e.g.:

clang: error: argument unused during compilation: '-c' [-Werror,-Wunused-command-line-argument]
clang: error: argument unused during compilation: '-c' [-Werror,-Wunused-command-line-argument]
clang: error: argument unused during compilation: '-c' [-Werror,-Wunused-command-line-argument]
clang: error: argument unused during compilation: '-c' [-Werror,-Wunused-command-line-argument]
clang: error: argument unused during compilation: '-c' [-Werror,-Wunused-command-line-argument]
clang: warning: argument unused during compilation: '-c' [-Wunused-command-line-argument]
clang: error: argument unused during compilation: '-c' [-Werror,-Wunused-command-line-argument]
clang: warning: argument unused during compilation: '-c' [-Wunused-command-line-argument]
clang: error: argument unused during compilation: '-c' [-Werror,-Wunused-command-line-argument]
clang: warning: argument unused during compilation: '-c' [-Wunused-command-line-argument]
clang: warning: argument unused during compilation: '-c' [-Wunused-command-line-argument]
clang: warning: argument unused during compilation: '-c' [-Wunused-command-line-argument]

This is how I set up the LLVM toolchain:

bazel_dep(name = "toolchains_llvm", version = "1.3.0")

LLVM_COMMIT = "14eb90172b3c5f35bdb2699d006fe0f70e76aa24"

archive_override(
    module_name = "toolchains_llvm",
    sha256 = "d85f78a501d6050fa0f1fb74e1c5f971549cd6d0b9c9147857935c0346c070d0",
    strip_prefix = "toolchains_llvm-{commit}".format(commit = LLVM_COMMIT),
    url = "https://github.com/bazel-contrib/toolchains_llvm/archive/{commit}.tar.gz".format(commit = LLVM_COMMIT),
)

llvm = use_extension("@toolchains_llvm//toolchain/extensions:llvm.bzl", "llvm")
llvm.toolchain(
    name = "llvm_toolchain",
    cxx_standard = {
        "": "c++23",
    },
    llvm_versions = {
        "": "20.1.0",
    },
)
use_repo(llvm, "llvm_toolchain", "llvm_toolchain_llvm")

register_toolchains("@llvm_toolchain//:all")

This is how I set up the extractor:

bazel_dep(name = "hedron_compile_commands")

COMPILE_COMMANDS_COMMIT = "4f28899228fb3ad0126897876f147ca15026151e"

archive_override(
    module_name = "hedron_compile_commands",
    sha256 = "658122cfb1f25be76ea212b00f5eb047d8e2adc8bcf923b918461f2b1e37cdf2",
    strip_prefix = "bazel-compile-commands-extractor-{commit}".format(commit = COMPILE_COMMANDS_COMMIT),
    url = "https://github.com/hedronvision/bazel-compile-commands-extractor/archive/{commit}.tar.gz".format(commit = COMPILE_COMMANDS_COMMIT),
)

And this is how I set up the command:

refresh_compile_commands(
    name = "refresh_compile_commands",
    targets = {
        "//modules/...": "",
    },
)

Is there any way to suppress/resolve those warnings/errors?
