To summarize: The graph coloring allocator was disabled in Jul 2008 after it was discovered that a bug in the allocator was causing issues with the pdd25cx branch and PGE.
It's been disabled ever since. There are some tests that rely on the allocator that have been TODO'd (originally numbered)
t/compilers/imcc/imcpasm/optc.t #9 t/compilers/imcc/imcpasm/opt0.t #1 and 3
The sub is graph_coloring_reg_alloc - once that is pulled out, there may be other then unused functions that can be removed.
