           Summary: -g0 file.S -g does not produce debug info
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: driver
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: jan.kratochvil@redhat.com
            Target: x86_64-fedora15-linux-gnu
             Build: x86_64-fedora15-linux-gnu

gcc -c -o 1.o 1.c -g: debug info produced
gcc -c -o 1.o 1.S -g: debug info produced
gcc -c -o 1.o -g0 1.c -g: debug info produced
gcc -c -o 1.o -g0 1.S -g: debug info not produced - IMO a bug

Why .c and .S behave differently wrt -g application rules?

Sure for .S there is just the .debug_line relevant.
