POOMA even has its own page in the GCC wwwdocs!
Ref. http://gcc.gnu.org/testing/testing-pooma.html

Did you look at the GCC testing pages? http://gcc.gnu.org/testing.  You
could try tree-ssa on the 5 C++ packages there and compare with mainline
(only if the results look good, of course ;-)

Diego,

Do you know where the memory increase comes from?

I was thinking of all the temporaries because each one of them needs a
tree_decl (108 bytes each on ia32) and an identifier (64 bytes each for
C++).  But I don't have the numbers, maybe you do?
