Yes, that would be lovely, but would likely be the size of a
street map of Seoul, S. Korea!
LinuxCNC is a large program, with lots of data being
accessed by many functions.
I think, maybe, the only way to actually do this is to have
a program that goes through the entire source, extracting
all structures and access to them, and put it all in a
database. Then, you could have a program that finds all the
structures that match an expression, and tells what
functions access that structure. Bonus points for showing
which functions write to the structure.
This would be a great tool, maybe somebody has written such
a tool. If not, I'll bet it would be found useful by a bunch
of others. To do it right, the scanning part of the program
might look a lot like a C compiler.
