Questionable code in gcov-io.c

[Marek Polacek]

While implementing a warning I noticed this in gcov-io.c:

 187   else if (mode == 0)
 188     {
 189       struct stat st;
 190 
 191       if (fstat (fd, &st) < 0)
 192         {
 193           fclose (gcov_var.file);
 194           gcov_var.file = 0;
 195           return 0;
 196         }
 197       if (st.st_size != 0)
 198         gcov_var.mode = 1;
 199       else
 200         gcov_var.mode = mode * 2 + 1;
 201     }
 202   else
 203     gcov_var.mode = mode * 2 + 1;

It seems that lines 198 and 200 do the same thing, at line 200 we know that
mode == 0, so we just assign 1.  Should we just remove the condition on line 
197?

This has been introduced in Jakub's r78281.
