The automated POOMA/tramp3d tester at
http://www.tat.physik.uni-tuebingen.de/~rguenth/gcc/monitor-summary.html
now tracks the maximum used virtual memory of cc1plus of mainline, too.
As a first "hint", today it revealed that mainline needs about 1GB of
ram compared to 3.4.1 which needs only 625MB. This is on ia64 for the
tramp3d-v3.cpp testcase at -O2 -funroll-loops -ffast-math with the
leafify patch included.
