Are the performance problems on SPEC2000int (and the improvements in
SPEC2000fp) concentrated in a single test?

Currently, bootstrap times on the branch are 14% slower than mainline
[...] Work is underway to remove some RTL passes

I once did experiments removing all gcse passes (-fno-gcse -fno-gcse-lm -fno-gcse-sm) and got no changes in resulting performance for the POOMA based applications.
