            Bug ID: 57850
           Summary: Option -fdump-translation-unit not working
           Product: gcc
           Version: 4.8.1
            Status: UNCONFIRMED
          Severity: critical
          Priority: P3
         Component: translation
          Assignee: unassigned at gcc dot gnu.org

Hi,

The -fdump-translation-unit option of the GCC compiler was broken in 4.8.1
(relative to 4.7.1).

Steps to reproduce:

1. Create any header file file.h
2. g++ -fdump-translation-unit file.h

g++ 4.7.1 dumps test.h.001t.tu, but g++ 4.8.1 does nothing.

May be this bug can be fixed like

Thank you.
