Remove unused load statements from .bzl files

After transitive loads have been disabled in Blaze, unused load statements have
no effect (besides not useful memory consumption).

The CL has been created automatically by calling `buildifier --lint=fix --warnings=load` on all .bzl files.

The following additional command were run on all affected files to clean them up:

  * buildifier -a -v --lint=fix --warnings=load-on-top
    Moves all load statements to the top of a file
  * buildifier -a -v --lint=fix --warnings=same-origin-load
    Compresses all load statements from the same .bzl file to one load statement

C++ rules for Bazel

Build status

This repository contains Starlark implementation of C++ rules in Bazel.

The rules are being incrementally converted from their native implementations in the Bazel source tree.

For the list of C++ rules, see the Bazel documentation.

Getting Started

There is no need to use rules from this repository just yet. If you want to use rules_cc anyway, add the following to your WORKSPACE file:

load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")
http_archive(
    name = "rules_cc",
    urls = ["https://github.com/bazelbuild/rules_cc/archive/TODO"],
    sha256 = "TODO",
)

Then, in your BUILD files, import and use the rules:

load("@rules_cc//cc:defs.bzl", "cc_library")
cc_library(
    ...
)

Migration Tools

This repository also contains migration tools that can be used to migrate your project for Bazel incompatible changes.

Legacy fields migrator

Script that migrates legacy crosstool fields into features (incompatible flag, tracking issue).

TLDR:

bazel run @rules_cc//tools/migration:legacy_fields_migrator -- \
  --input=my_toolchain/CROSSTOOL \
  --inline

Contributing

Bazel and rules_cc are the work of many contributors. We appreciate your help!
