As a normal user of gcc, what's the difference between 
rtl-optimization and tree-optimization?

Really.  I did 

gfortran -c -O0 z.f90  (This compiles.)
gfortran -c -O1 z.f90  (This compiles.)
gfortran -c -O2 z.f90  (ICE on valid code.)

There is no clue for a normal user to decide between
rtl- and tree-.  Someone with way too much compiler
writing skills is splitting hairs for the normal user.
