[OpJumpFalse, OpAndJump, OpOrJump, OpJump], these four instructions have been changed to use 4 bytes to avoid precision loss and panic when the number of instructions exceeds the maximum of 16 bits (65535)

LGTM

Tests don't seem to be passing. Reverting for now....

@wlxwlxwlx can you look into the cause please?

[wlxwlxwlx]

Can you send me the test cases that failed? Let me see what the problem is.

If true {10}; 3333 An error was reported while executing this test case, and I tracked the code. On line 269 of compiler.go.

When [OpJumpFalse, OpAndJump, OpOrJump, OpJump] is changed to int32, each instruction becomes 4 bits (previously 2 bits), so when executing curPos:=len (c. currentInstructions()), curPos becomes 10 instead of 8. All subsequent test cases, as long as these 4 instructions are used, the value of curPos will be larger than before (the difference between the values of curPos in the fix/jump and master branches must be a multiple of 2). Therefore, if this pr is merged, the test cases need to be updated. I submitted an updated PR, please take a look.
