An Interesting one but I don't agree with everything, e.g. all aspects of using
attribute(packed).

A very good idea. Please go for it. I think doing this in a group would
become even better, and in the long run it could grow into a good wiki page
that lots of people may want to read. Perhaps even a Usenix paper...
Of the tips in the article, I like the following ones:
#4: Considering register usage, especially in parameter passing
#3/5/6: Mixing C and assembler when it makes sense
For #7, I'd start a discussion about LLVM, noting that we haven't tried it yet.
#8 is nice but rarely needed or used
I disagree with #9, the compiler should do this when useful, and the
explanation is not 100% correct.
Besides those, we have the things I tried to explain in one of the talks at the
Hackathon. We need to get that out at some point. Anyone wants to help,
perhaps you Jose? Just say so and I'll find the time to place the slides into
github.
