I broke the signedBitShift: used by B2DPlugin which might easily explain having only one quadrant right (the + + combination). I broke it on march 10 by my attempt to fix Crypto plugin... Sounds weird, but I had to change the Slang CCodegenerator so as to generated correct bit shifts...

This is one of the most dangerous and scary operations.

...which brings us back to unit tests of code generation... Without such net, acrobats' life is dangerous!

Agreed. We should also integrate Phillipe’s tests. One thing to do is to regenerate all sources whenever one changes Slang (touch -t is your friend here), use revertIfEssentuallyUnchanged to get rid of the noise and then git diff to eyeball the changes.

Since then, I did only eat my 64 bits dog food which did not show the bug Instinct probably kept me away from rotten 32 bits meat :(

Hi,

In the attached image does anyone seem to have an idea what is going wrong with curve drawing?

The lower left of circles and vertical lines seem ok. The other quadrants of a circle are wrong in consistent but different ways.

Related, has anyone tried a 32 bit Squeak recently?

Thanks.
