Bug in Propeller Tool 1.05.7?

edited 2007-11-18 22:28 in Propeller 1
When I try to compile the following spin file in 1.05.7 I get a "Expression is too complex" error. This error does NOT occur with 1.05.5. The part of the code it barfs on:
                        cmp dutyold, duty2 wz, wc         ' If Z or C is set then they're the same
        IF_E            jmp #:do_nothing_again            ' They're the same, so skip this code below 
                        mov multiplicand, pwmfbase
                        mov multiplier, duty2
                        jmpret multiply_ret, #multiply
                        mov pulsewidth2, product              
:do_nothing_again


It does not like the line with the IF_E and highlights the "#:do_nothing_again" part. Why is this? If I make the label shorter to something like ":do_nothing_b" it works ok. If I change the label to :do_nothingagainhaha it also works. What gives?

Gr,
Mightor

    It obviously happens, when the label takes exactly 16 characters? But only for local labels.

    This bug happened between 1.05.5 and .7, those labels worked fine with .5 :-/ I did test it with a label called :do_nothing_aagain and that seems to be fine, so you're right, it's exactly 16 chars long. Weird.

    It gets even weirder:
    The bug seems to have reincarnated from version 1.05.2:

    Well it's not really weird... it's one of the most popular situations with "configuration control": 
    

version x.2--+-------------------> released
             |
             +--- version x.5 ---> released
             |
             +--- version x.7 ---> released



    Hope I am wrong smile.gif

    ;-)

    I promise that our code and·our configuration control·doesn't resemble that plate of food.· Getting hungry though.

    ;-)



    I noted the error and duplicated it again here.· We'll get it fixed for good this time and will re-release as soon as possible.

    Sorry for the trouble.

    Jeff,
    Can you release a change log to accompany the new version? It would erase a lot of confusion between manual, errata and these often misplaced threads.
    Fred

    Duh, there's readme.txt file in the parallax root that has all of the version info. And yup, it's bundled (and updated) in each version.

    This is my fault. It seems I've got a phase error between code at work and code at home. Fixing this is going to be a matter of maybe 20 characters of source code. I happen to be on vacation right now and I don't have access to the source code, but I will be back at the end of the week, so we will post·a new version·next Monday. Sorry about this.

    hahaha, You got an apology from the real developer, and not from some marketing guy. That In my eyes brings solution ages faster, and most probably does not include any new acronyms you did not know about, for free jumpin.gif

    People, we still need some *open source* tools to complement what they provide (great editor, by the way). I was busy with other things, but I left pPropellerSim in the state of implementing propeller/eeprom programming smile.gif, I'll continue with that as soon as I can, or post it for other to contribute...

    If you come down with a bad case of "Phase Error", take one dose of Subversion and call me in the morning...

    http://subversion.tigris.org

    Actually I think Git is theoretically much better than Subversion as a version control system, but Git is in-comparison is a bear to deploy & run IMHO due to lack of decent documentation. If you're used to using source-code as documentation however, do have a go at Git.

    http://git.or.cz

    Git is currently the versioning system of choice for development and maintenance of the Linux Kernel. A key selling point for me when it comes to Git is the way it seems to save distributed archives and then synchronize under the control of hashes which act as version signatures. This allows archives to be transportable, and the distributed nature adds robustness.

    Subversion is released under the Apache/BSD license, Git is released under GPL2.

    Hmmm, Subversion.

    I had someone "help" me with a bit of code. It was my first cooperative programming effort in quite a while, and the other conviced me that we should use subversion (but could have been any versioning tool).

    The code was run by the other programmer through a "beautifier", dutifully checked into subversion, and the diff files sent back to me. The result - thousands of "changes" across 100K+ lines of code!! The programmer didn't even think about what he was doing - he had subversion "So all was OK".

    As a single developer - I don't believe in electronic versioning software. Unless you actually take the time to check every change, then I think you're bluffing yourself.

    Just my opinion - it probably wont be popular.

    To err is human, to really stuff up you need a computer.

    Hi,

    Attached is the version (v1.05.8) that fixes this 16-character label bug (that was mistakenly reintroduced).

    You can also download this version with an installer from our website soon (10-9-2007).

    Also attached is the readme file that comes with the installer; it includes details of changes in various versions.

    Thanks.

    This version was only to address bug fixes, while you may feel the·lack of setting of the COM port is a bug, it's actually a feature and isn't addressed (yet).

    Hello everyone!

    Talking about bugs or errors in the editor, I've seen one in v 1.05.8, and it's been there for a quite long time now...
    When I first start up the editor the "object view pane" isn't visible until I've had two files opened at the same time. Then I'm able to close one file without that it disappears. But because I'm working with one file quite a lot of the time this isn't very fun when you find out that you need to open one of the sub-objects (the easiest way of doing this is to click it in that pane!) you need to open a another file first!
