tools/reorder/ has a lot of code that appears to be be devoted to an attempt to reorder functions in binaries to improve performance. grope.cpp has a comment at the top: > A program that computes a function ordering for an executable based > on runtime profile information. > > This program is directly based on work done by Roger Chickering > <firstname.lastname@example.org> in > > <http://bugzilla.mozilla.org/show_bug.cgi?id=65845> > > to implement Nat Friedman's <email@example.com> `grope', > > _GNU Rope - A Subroutine Position Optimizer_ > <http://www.hungry.com/~shaver/grope/grope.ps> > > Specifically, it implements the procedure re-ordering algorithm > described in: > > K. Pettis and R. Hansen. ``Profile-Guided Core Position.'' In > _Proceedings of the Int. Conference on Programming Language Design > and Implementation_, pages 16-27, June 1990. All this code was checked in by Chris Waterson in November 2001 with a commit message that only said "First commit". I don't know if there's a bug associated with it. It has only received trivial license and grammar-nazi changes since then, e.g. see: https://github.com/mozilla/gecko-dev/tree/7756488dffc09f67790b14d2141f640aefd662b7/tools/reorder Unsurprisingly, it doesn't compile, and the whole enterprise sounds like something that should be done as part of PGO builds or not at all.
