Extend MTE gdbstub tests to also run in system mode (share tests between user mode and system mode). The tests will only run if a version of GDB that supports MTE on baremetal is available in the test environment and if available compiler supports the 'memtag' flag (-march=armv8.5-a+memtag). For the tests running in system mode, a page that supports MTE ops. is necessary. Therefore, an MTE-enabled page is made available (mapped) in the third 2 MB chunk of the second 1 GB space in the flat mapping set in boot.S. A new binary, mte.S, is also introduced for the tests. It links against boot.S and is executed by QEMU in system mode.

This directory contains various interesting guest binaries for regression testing the Tiny Code Generator doing system and user-mode emulation. The multiarch directory contains shared code for tests that can be built for all guest architectures. Architecture specific code can be found in their respective directories. System mode tests will be under the "system" subdirectories. GDB scripts for exercising the gdbstub on specific tests will be found under the "gdbstb" subdirectories. See the developer guide for more instructions on "make check-tcg"
