for current trunk and the original testcase, timings are reasonable at -O0 -O1
-O2, but very long at -O3 (>60min):
report.O0.txt: TOTAL : 38.78 0.89 39.67
691166 kB
report.O1.txt: TOTAL : 70.04 1.13 71.22
634523 kB
report.O2.txt: TOTAL : 204.51 1.16 205.71
691522 kB
the biggest consumers are
-O0:
====
integrated RA : 10.36
reload : 5.16;
-O1:
====
tree PTA : 7.77
integrated RA : 13.36
-O2:
====
expand vars : 83.15
tree PTA : 35.04
-O3: (also needs about 4Gb of memory)
====
??? not yet finished (>60min)
