Generates random proper list of following JVM instructions: * -Integer constants: ICONST_M1, ICONST_0, ICONST_1, ICONST_2, ICONST_3, ICONST_4, ICONST_5 * -Integer arithmetics: IADD, ISUB, IMUL, IAND, IOR, IXOR, ISHL, ISHR, INEG * -Stack operations: DUP, SWAP * -NOP * (If loadFrom command line option is setted, test will be use instruction sequence from file. * It is useful for reproducing failures.) * 2. Executes this sequence in to ways: with TinyInstructionsExecutor and HotspotInstructionsExecutor. * 3. Checks that results of execution are equals. * For generation instructions test using right parentheses sequence. Open parenthesis "(" is correspondent to * stack increasing instructions, ")" is corresponded stack decreasing instructions. * * @library /vmTestbase * /test/lib * @run driver jdk.test.lib.FileInstaller . . * @run main/othervm vm.compiler.coverage.parentheses.Parentheses */
