Arm has officially sunset the Transactional Memory Extension (TME) for the AArch64 architecture due to a lack of implementations. In line with this, GCC is beginning a deprecation cycle for TME. This involves removing mentions from documentation, issuing warnings when the TME option is used during compilation, and removing associated test cases.
