Tree dumps and (garbage?) local variables

- Subject: Tree dumps and (garbage?) local variables
If looking at tree-dumps in later optimization phases I get distracted
by pages of local variables declared that are never used in the function.
Like f.i. 573 lines of var-decls for 88 lines of code (including empty
lines and labels).
Are these really still hanging around? Do they maybe consume still
memory (during compilation)? Where in the tree-dumper do I need to look
to implement sth like -fdump-strip-unused-variables?
Thanks for any hints!
Richard.
