[New-bugs-announce] [issue45388] Use JUMP_FORWARD for all forward jumps.

[Mark Shannon]

New submission from Mark Shannon <mark at hotpy.org>:

Python has two unconditional jumps, JUMP_ABSOLUTE and JUMP_FORWARD.

The bytecode compiler should ensure that all forward jumps use JUMP_FORWARD and all backwards jumps use JUMP_ABSOLUTE.

That way, the interpreter will know that JUMP_ABSOLUTE jumps are backwards and won't need to check.
