problems with -fdump-tree options (gcc 4.0.0)

[Nico Moser]

Hi,

I tried the following:
gcc -fdump-tree-all-all -c -o bla.o bla.c

and I got these:
bla.c.t02.original
bla.c.t03.generic
bla.c.t06.vcg
bla.c.t08.gimple
bla.c.t09.useless
bla.c.t11.lower
bla.c.t12.eh
bla.c.t13.cfg
bla.c.t14.oplower

I have two questions:
Where is the bla.c.t**.optimized file?
What is the bla.c.t03.generic file? The same as the  
bla.c.t02.original? I can't found it in the onlinedocumentation.

Thanks a lot.
Nico
