re-entrancy of @MUL1616
PostPosted: Mon Jan 05, 2009 12:17 pm     Reply with quote

I'm getting a warning about interrupts being disabled to avoid re-entrancy in @MUL1616. Of course, this is because this routine gets used both inside and outside an interrupt routine.

Using #ORG, I've managed to create a 2nd copy of MUL1616. Looking at the assembly code, I can see there are now @MUL1616 and @@MUL1616 at different locations.

I can see every call to these two routines, and I can see where some blocks of code that I think should be inside ORGed areas are not where I expect them to be. And this results in them using the wrong copy of MUL1616.

At first is seemed liked #INLINE functions weren't getting properly placed. But now I'm not sure...

And I'm suffering from a rare system crash that seems to result from interrupts being disabled at a bad time. Any suggestions on how to rein in the #ORG thing and ensure the right copies of MUL1616s are getting used?

The only other solution I can think of is to write my interrupt routines in assembler. Geez, I'd rather not have to do that right now... I quit using PicBasicPro 'cause I had to do that in every project. :)

Thanks,

Post a short but complete test program. Post only the code that is
necessary to show the problem (no Wizard code). The program must
be compilable without errors. It should have an #include, #fuses, #use
delay, and a main().

Also post your compiler version.
