We autodetect the presence of FPRCVT in the test cross compiler, which is a recent feature in GCC and not supported by many distros yet. If this is in place, we compile the existing fcvt.c test with an extra compiler flag which uses the new SIMD instructions; the output from the test is unchanged. The existing [US]CVTF instructions do not have a test, so no new tests are added for the SIMD versions. They have been tested manually to check the new SIMD versions produce the same numerical results as the existing versions.

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"
