Warning: Unexpected arithmetical precedence with unary minus

Warning: Unexpected arithmetical precedence with unary minus

Closed this issue 3 years ago · 3 comments

This new warning showed up with the latest xas99.py. These arithmetic expressions should be unambiguous. Seems like the unary minus is causing the warning:

> hero.asm <2> 0678 -        AI R5,-8*256
***** Warning: Unexpected arithmetical precedence
> scroll.asm <2> 0234 -        AI R4,(-32*22)-1
***** Warning: Unexpected arithmetical precedence
> scroll.asm <2> 0291 -        AI R4,(-32*22)+1
***** Warning: Unexpected arithmetical precedence
> movobj.asm <2> 0441 -        AI R5,(-32*256)+16
***** Warning: Unexpected arithmetical precedence

Yeah, sorry, I missed some cases for that check ... I hope to release a fix this weekend.

Thank you. I appreciate all the work you've done lately.

I've pushed a fix for xas99 and xga99 regarding this issue. I hope I covered all cases now.

Please download xas99 directly, as I'm still waiting for a solution to the IDEA plugin code completion issue before I publish another release.

Thanks for reporting this so quickly!
