namespace v8 {
namespace internal {
// Test infrastructure.
//
// Tests are functions which accept no parameters and have no return values.
// The testing code should not perform an explicit return once completed. For
// example to test the mov immediate instruction a very simple test would be:
//
// TEST(mov_x0_one) {
// SETUP();
//
// START();
// __ mov(x0, Operand(1));
// END();
//
// RUN();
//
// CHECK_EQUAL_64(1, x0);
// }
//
// Within a START ... END block all registers but sp can be modified. sp has to
// be explicitly saved/restored. The END() macro replaces the function return
// so it may appear multiple times in a test if the test has multiple exit
// points.
//
// Once the test has been run all integer and floating point registers as well
// as flags are accessible through a RegisterDump instance, see
// utils-arm64.cc for more info on RegisterDump.
//
// We provide some helper assert to handle common cases:
//
// CHECK_EQUAL_32(int32_t, int_32t)
// CHECK_EQUAL_FP32(float, float)
// CHECK_EQUAL_32(int32_t, W register)
// CHECK_EQUAL_FP32(float, S register)
// CHECK_EQUAL_64(int64_t, int_64t)
// CHECK_EQUAL_FP64(double, double)
// CHECK_EQUAL_64(int64_t, X register)
// CHECK_EQUAL_64(X register, X register)
// CHECK_EQUAL_FP64(double, D register)
//
// e.g. CHECK_EQUAL_64(0.5, d30);
//
// If more advance computation is required before the assert then access the
// RegisterDump named core directly:
//
// CHECK_EQUAL_64(0x1234, core.xreg(0) & 0xFFFF);
#if 0 // TODO(all): enable.
