| The set of targets whose <a href="${link make-variables}">Make variables</a> this target is |
| allowed to access. These targets are either instances of rules that provide |
| <code>TemplateVariableInfo</code> or special targets for toolchain types built into Bazel. These |
| include: |
| |
| <ul> |
| <li><code>@bazel_tools//tools/cpp:current_cc_toolchain</code> |
| <li><code>@bazel_tools//tools/jdk:current_java_runtime</code> |
| </ul> |
| |
| <p> |
| Note that this is distinct from the concept of |
| <a href="/docs/toolchains#toolchain-resolution">toolchain resolution</a> |
| that is used by rule implementations for platform-dependent configuration. You cannot use this |
| attribute to determine which specific <code>cc_toolchain</code> or <code>java_toolchain</code> a |
| target will use. |
