            Bug ID: 86817
           Summary: [8/9 Regression] Misleading warning in gcov since
                    r254672
           Product: gcc
           Version: 9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: gcov-profile
          Assignee: unassigned at gcc dot gnu.org
          Reporter: marxin at gcc dot gnu.org
                CC: marxin at gcc dot gnu.org
  Target Milestone: ---

When gcov is run for 2 files one can see:

$ rm *.gc* ; gcc --coverage main.c && ./a.out && gcc --coverage main2.c &&
./a.out && gcov main.c main2.c
main2.gcno:'main' has arcs to entry block
main2.gcno:'main' has arcs from exit block
File 'main.c'
Lines executed:100.00% of 2
Creating 'main.c.gcov'

File 'main2.c'
Lines executed:100.00% of 2
Creating 'main2.c.gcov'

Which is obviously wrong.
