Accessing the file scope C++ data structs in GIMPLE

[Prateek Saxena]

Hello,

I want to dump out all the c++ classes/structs and global data
structures defined in a given file scope or transaltion unit, as  part
of the debug dumps in C-like syntax, from GIMPLE data structs. Is
there a TREE_VEC or BIND_EXPR_VARS that I can traverse through and get
all these ?

Thanks a lot for the help provided in the past as well.

Thanks,
Prateek.
