Seen with code compiled with -Os, where an LongJmp (Buffer, -1)
somehow translated to SetJmp returning 0...

I suppose there is some internal policy at Intel that tells you to
claim copyright, but do you really think fixing existing HP code by
removing 4 instructions and adding one back is sufficient for claiming
copyright on the entire file?

Note that I am not objecting to this in principle: I am just curious
(and I have objected in the past to patches that only removed lines
from existing code and then added a copyright line)

Should we have some project/community wide guidance on this?

I reacted early on when joining this project that copyright was frequently added/bumped for trivial changes, including things like fixing typos in comments. So I think the custom for this project is that the bar is a lot lower than for projects like Linux, grub, etc.

So I see this as on par for tianocore.

(The problem is that claiming copyright gives the right to distribute
the code without being bound by the terms of the license)

Wouldn't all the other copyright holders also need to agree?
