I apologize if this has been discussed before, but a search came up with practically nothing on the topic.
Has anyone successfully gotten gcov to work on an AVR target? The only information I've come up with is that one needs to implement the standard file IO functions (not a problem), and that the AVR possibly doesn't support an instruction needed by the -fprofile-arcs parameter when compiling with optimization (which would definitely be a problem).
If anyone has this working, I'd love to hear about it. I'm trying to avoid going to the trouble of setting up a remote file system for something that won't work anyway.
