 Reasons for Non-Reproducible Builds
 -----------------------------------
@@ -46,6 +47,7 @@ ESP-IDF achieves reproducible builds using the following measures:
     - Path to the project is replaced with ``/IDF_PROJECT``
     - Path to the build directory is replaced with ``/IDF_BUILD``
     - Paths to components are replaced with ``/COMPONENT_NAME_DIR`` (where ``NAME`` is the name of the component)
+    - Path to the toolchain is replaced with ``/TOOLCHAIN``
 
 - Build date and time are not included into the :ref:`application  metadata structure <app-image-format-application-description>` and :ref:`bootloader metadata structure <image-format-bootloader-description>` if :ref:`CONFIG_APP_REPRODUCIBLE_BUILD` is enabled.
 - ESP-IDF build system ensures that source file lists, component lists and other sequences are sorted before passing them to CMake. Various other parts of the build system, such as the linker script generator also perform sorting to ensure that same output is produced regardless of the environment.

     - 替换项目路径为 ``/IDF_PROJECT``
     - 替换构建目录的路径为 ``/IDF_BUILD``

 - 如果启用 :ref:`CONFIG_APP_REPRODUCIBLE_BUILD`，则不会将构建日期和时间包括在 :ref:`应用程序元数据结构 <app-image-format-application-description>` 和 :ref:`引导加载程序元数据结构 <image-format-bootloader-description>` 中。
 - ESP-IDF 构建系统在将源文件列表、组件列表和其他序列传递给 CMake 之前会对其进行排序。构建系统的其他各个部分，如链接器脚本生成器，也会先排序，从而确保无论环境如何，输出都一致。
