Optimizer bug (*solved*)

[einar]

I found an error in ZX BASIC optimizer. Take a look at this test program:

Code:

GO TO 10 sub FASTCALL test(flag AS UBYTE) asm cp 1 jp m,45000 jp 50000 end asm end sub 10 POKE 50000,201: POKE 45000,201 test(1)

This program produces the expected result if you compile it as follows:

Code:

zxb.exe -t -O2 prog.bas

However it will refuse to compile if you use this instead:

Code:

zxb.exe -t -O3 prog.bas

In this latter case it will produce this error message:

Code:

C:>zxb.exe -t -O3 prog.bas Traceback (most recent call last): File "zxb.py", line 348, in <module> File "zxb.py", line 301, in main File "optimizer.pyc", line 2287, in optimize File "optimizer.pyc", line 1493, in update_goes_and_comes KeyError: '45000'

EDIT: Tested using latest ZX BASIC version 1.4.0s1898.

I think I've fixed it in the Lastest version, 1.4.0s1902. Can you download and check it, please?
