Hello.

Good start. You branched the repository but your forget to push the commit
you sent as attachment. Second issues is that the patch is not against
GCC trunk, but against your local branch. Thus one can't apply that.

About the options:
- once you send a new functionality, it's fine to paste a sample output
- for now I would remove the dummy flag_lto_dump flag
- I would expect for -fdump-lto-list something like what nm does:

$ nm main.o
00000000 T main
00000000 T mystring
00000000 C pole

Then of course you can add some level of verbosity which can print what you have.
Would be also handy during the time to come up with some sorting, but it can wait.

That said, the direction is fine. Please carry on.

Thanks,
Martin
