     1.4 +SH4 instruction set tests.
     1.5 +Each core instruction has its own set of tests that are assembled into the
     1.6 +main test executable.
     1.7 +
     1.8 +Note: Since each instruction's tests obviously depends on other
     1.9 +instructions, its possible for multiple bugs to cancel each other out.
    1.10 +However the tests are structured as much as possible to prevent this.
    1.11 +
    1.12 +Each test loops repeatedly for a constant number of times (currently 1000)
    1.13 +to a) ensure that dynamic recompilation kicks in and recompiles the block,
    1.14 +and b) allow the code to be timed (to a first approximation anyway).
