|
* DESCRIPTION
|
|
* This test works as follows:
|
|
* 1. 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.
