Hi,
this patch fixes PR66851.
In parloops, we manage to parallelize outer loops, but not if the inner

Hi,
patch below prints the function attributes in the dump file.
Say we mark a function foo with attributes noinline and noclone like this:
...
int __attribute__((noinline, noclone))
foo (void)
...
Then using this patch, we find in the dump file:
...
;; Function foo (foo, funcdef_no=10, decl_ui
;3rd-level restrict ignored".

Good idea?
If so, do we want one attribute per line?
