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"
