Just out of curiosity. Is there a way to tell the linker that ISRs have the same priority and thus cannot interrupt each other and can safely be overlayed?
P.S.: And what is the correct passive form of 'to overlay'?
There are linker controls to manually specify the overlaying...
I know those and make intense use of them, but aren't interrupts always root nodes?
Can I create a virtual function that calls them, which really only exists in the call tree and not in the code?
Should I write a function for each priority level that calls all the ISRs of the same priority? But I'd expect ISRs are subject to a number of special treatments by the compiler and linker. I'm afraid the effects could be quite destructive.
