Forgotten JP

[einar]

NIRVANA demo code ends like this:

Code:

DO
        ...
        FOR sprite = 0 TO 7
            ...
        NEXT sprite
    LOOP
btiles:
    asm
        incbin "nirvana.btile"
    end asm

Previous versions of ZX BASIC compiled it correctly. Latest version 1.4.0s1964 now compiles it incorrectly, as follows:

Code:

__LABEL47:
    ld a, 7
    ld hl, (_sprite - 1)
    cp h
    jp c, __LABEL2
__LABEL__btiles:
#line 132
    incbin "nirvana.btile"
#line 133

It's now forgetting to generate the last JP corresponding to the DO..LOOP statement!

If you would like to compile it yourself, source code is available here:

This is another serious bug based on the optimizer change after version s1935.
Can you download ZXBasic Version 1.4.0s1967 and tell me if it works now, plz? :roll:
