 Currently we are in a very early stage, trying to cross compile the AOSP codebase
 using the RISC-V official GNU toolchain. The following is the project progress log (time in reverse order).
 
+- 2021-11-30 For AOSP 12 ported to RV64, the implementation of `mmm bionic/libc/ --skip-soong-tests` was successfully built, we now have libc/libm/libdl. The relevant changes have been submitted to the repositories. The details are as follows (here, some PRs are created on gitee, all commits are pushed both on github & gitee):
+  - toolchain for AOSP：
+    - Rust for Android:
+      - compiler: add riscv64gc-linux-android target (Tier 3): <https://github.com/aosp-riscv/rust/commit/8397a76b895b586dcfc8637e98908f65df1af1f9>
