Re: [avr-libc-dev] SIGNAL / INTERRUPT checking

[Colin O'Flynn]

Hi,

Thought of another idea.

Search the input files for the SIGNAL() or INTERRUPT() macro, and get the 
interrupt name (BTW are SIGNAL() and INTERRUPT() case sensitive?), then 
search the output file for them. If it finds any it means they were not 
converted... also search for any SIG_ for good luck (to catch anything else). 
This way for most you can get line information to report back.

Just working on the prototype now so testing out different ideas...
