// These simulator tests check instruction behaviour against a trace taken from
// real AArch64 hardware. The same test code is used to generate the trace; the
// results are printed to stdout when the test is run with
// --generate_test_trace.
//
// The input lists and expected results are stored in test/traces. The expected
// results can be regenerated using tools/generate_simulator_traces.py. Adding a
// test for a new instruction is described at the top of
// test-simulator-traces-aarch64.h.
