I'm trying to hack the the C compiler's cc1 module to spit out lots of
useful (to me) information about structures and/or typedefs that it
processes.

Can anyone offer me help or _documentation_ on how the compiler uses and
manages trees or lists or lists of trees or trees of lists?  I've been
stepping through the compiler code with the debugger and am beginning
to get a glimmer of what's going on, but I'm lacking the "big
picture."  Any pointers would be appreciated.

What I'd really like is to find all the typedefs and print out detailed
info about their base classes, including the components of any
structures involved.  So when I find a typedef, I need to find what it's
refering to, and if that is a structure, I need to examine all of it's
components, and if any of those components are structures (directly or
thru typedef'ed types), I need to delve into those, recursively.


Or maybe I should just sell life insurance.  ;->
