-"""Config settings for compilers identified by Bazel.
-
-Targets that require compiler-specific flags can use the config_settings defined
-in this package in their select() statements.
-
-*Note*: Before Bazel 6, gcc on Linux and clang on macOS would not match their
-specific config_setting, but only the fallback case of a select expression.
-
-Toolchains not shipped with Bazel are encouraged to use the same names to
-identify compilers as used below, but this is not enforced.
-
-Example:
-
- cc_binary(
- name = "foo",
- srcs = ["foo.cc"],
- copts = select({
- "@rules_cc//cc/compiler:gcc": [...],
- "@rules_cc//cc/compiler:clang": [...],
- "@rules_cc//cc/compiler:msvc-cl": [...],
- # Fallback case for an undetected compiler.
- "//conditions:default": [...],
- }),
- )
-
-If multiple targets use the same set of conditionally enabled flags, this can be
-simplified by extracting the select expression into a Starlark constant.
