| # Creates a symlink from root_build_dir/target_name to |binary_label|. This rule |
| # is meant to be used within if (current_toolchain == default_toolchain) blocks |
| # and point to targets in the non-default toolchain. |
| # Note that for executables, using a copy (as opposed to a symlink) does not |
| # work when is_component_build=true, since dependent libraries are found via |
| # relative location. |
| # |
| # Args: |
| # binary_label: Target that builds the file to symlink to. e.g.: |
| # ":$target_name($host_toolchain)". |
| # binary_output_name: The output_name set by the binary_label target |
| # (if applicable). |
| # output_name: Where to create the symlink |
| # (default="$root_out_dir/$binary_output_name"). |
| # |
| # Example: |
| # if (current_toolchain == host_toolchain) { |
| # executable("foo") { ... } |
| # } else if (current_toolchain == default_toolchain) { |
| # binary_symlink("foo") { |
