Believe me, they did. The new project was started
precisely because the code for Gnu Rope was never
released, and multiple attempts by multiple people
over multiple years to contact the author were
unsuccessful.
If you think development of Gnu Rope should be restarted,
by all means, contact the author of grope and see if
you can get him to release his code. Good luck.
As far as I know, he doesn't return email (he's kind
of a high profile guy these days, and has probably
moved on from actually writing code to drinking
pina coladas or something.)

Maybe, but that might well be a temporary problem.
There is an experimental port of valgrind to PowerPC-based GNU/Linux.
If that can be done, x86-64 should be easier.

Nevertheless starting a project that uses valgrind, so it can only work on
intel 32bit platform is really bad idea.

Unfortunately GNU Rope was abandoned, as it only had one developer, and
that developer subsequently devoted all his time to starting a company
(Ximian).

It sounds like you're reinventing GNU Rope.
You may want to look at this:

Hi everyone,
We're releasing into the public a new tool for reordering functions in
Linux libraries and executables. Here is a blurb from the
introduction posted on the website:
---
The software that was built for this project will ultimately be used
in improving the performance of Linux applications that depend on
shared libraries. By profiling the program and analyzing the behavior
of function calls throughout its lifetime, the tool will provide a way
to rebuild the applications and libraries such that highly-dependent
functions are placed near to each other in memory. This should
decrease the amount of time spent swapping data from disk to memory
and reduce the frequency of misses in the translation lookaside buffer
(TLB).
---
Currently, the tool exists as a small shell/Perl script which gathers
information from existing profiling tools (Valgrind/Callgrind) and
outputs a new ordering in a GNU ld linker script. This is a very
early release and is not intended for production use yet. It works
only on x86.
Please feel free to peruse the site. We appreciate any help you all
would care to offer.

Thanks,
Brandan, Alex, and Will
