When I compile with:
g++41f -O2 -ftree-vectorize -c -o vectest.o vectest.cpp -finline-functions
-funswitch-loops -fgcse-after-reload -fdump-tree-all
it works, but with
g++41f -O3 -ftree-vectorize -c -o vectest.o vectest.cpp -finline-functions
-funswitch-loops -fgcse-after-reload -fdump-tree-all
it ICEs.
Reading the manual there should be no difference.
Using -O3 the dump vectest.cpp.t71.ivopts is the first dump which no longer
contains main().
