Processor Expert insists on using undefined pragmas

GaryOlmstead — Thu, 16 Apr 2009 01:40:25 GMT

Same project as my last message. Processor Expert generates a "#pragma interrupt alignsp saveall" line, which leads to a Link Error: Undefined: INTERRUPT_SAVEALL" and also "Undefined: INTERRUPT_RESTOREALL" errors. I can't find saveall or restoreall documented, and when I type "#pragma" and then Alt ., saveall and restoreall don't show in the pop up window. Deleting the saveall gets rid of the error, but PE restores it the next time it runs.

How can I either 1) tell CW that saveall and restoreall are legit, or 2) persuade PE to stop adding them every time it runs?

Hi,

If you're using Processor Expert, your application should contains a Generated Code folder.

All files listed in this folder are re-generated when you re-build the project by Processor Expert.

By default the user mus not change code for all these files.

If you need to adapt the generated code you can freeze Processor Expert with the option Processor Expert ¦ Frezze Generated code.

By this way Processor Expert will freeze the code and you can modify the source files in Generated code Folder.

However if you need to change something in Processor Expert for instance adapt a bean or add another one, all your modification will disappear if your re-generate the Processor Expert Code.

Now Regarding the problem with Interrupt.

I can not explain why the code generated by Processor Expert introduces linker error.

I suspect a problem with the project configuration.

Can you check your project ?

If you don't find what is the trouble, we could try on our side.

To do that we need your project.

Regards

Pascal

Well, yes, but check it for what?

Hi,

I think something must be wrong in your project but I can not provide you more info.

May be it's related to the previous question you posted.

I don't know.

Hi Pascal --

I stumbled across the answer. There is a file called save_reg.asm that contains two routines. One is INTERRUPT_SAVEALL and the other is INTERRUPT_RESTOREALL. As you've probably guessed, it's out in the middle of nowhere. Specifically: "C:\Program Files\Metrowerks\CW for 56800\M56800E Support\runtime_56800E\save_reg" at least on my computer; yours will be identical after CW for 56800.

Thanks for your help and support.

Gary
