I used the command bellow:
gcc -fdump-tree-ssa hello.c
to dump the file in SSA form. However, I can't find the file in the
directory.It seems that the file wasn't dumped at all.
I tried this in different version of GCC,but it was the same in the
GCC4.1.1,4.2.3 and 4.3.0.
I wonder that if someone could tell me the exact reason~Thanks a lot~

You haven't asked gcc to do any optimization, so the tree-ssa passes
never run and there's nothing to dump. You need to specify an
optimization level higher than the default 0.
