hlopko b308aae57f Add ctx argument to cc_common.configure_features 
In order to migrate C++ rules to platforms, we need the access to the C++
configuration fragment in Starlark APIs. All existing APIs have already access
to it, but cc_common.configure_features doesn't. This change adds a
ctx argument to configure_features.

This is the migration needed for
https://github.com/bazelbuild/bazel/issues/7793, and is part of the effort for
https://github.com/bazelbuild/bazel/issues/6516.

If the rule doesn't depend on cpp fragment yet, you will have to add `fragments
=['cpp']` argument to the rule() call.

Note that this behavior is only available in Bazel 0.25 (to be released this month).

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:rules.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
