            Bug ID: 43850
           Summary: Make GNU style symbol printing invalid symbol section
                    indexes match GNU readelf
           Product: tools
           Version: trunk
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: llvm-readobj
          Assignee: unassignedbugs at nondot.org
          Reporter: jh7370.2008 at my.bristol.ac.uk

When a symbol's st_shndx value is invalid due to it being larger than the
number of sections, GNU readelf prints "bad section index[ XX]" for the section
index column (where XX is the raw value). This also applies if the value is
derived from the .symtab_shndx section:

C:\Work> readelf --symbols test.o

Symbol table '.symtab' contains 3 entries:
   Num:    Value  Size Type    Bind   Vis      Ndx Name
     0: 00000000     0 NOTYPE  LOCAL  DEFAULT  UND
     1: 00000000     0 NOTYPE  LOCAL  DEFAULT bad section index[ 67] invalid
     2: 00000000     0 NOTYPE  LOCAL  DEFAULT bad section index[ 42]
invalid_shndx

llvm-readelf prints simply the value (derived from the .symtab_shndx section if
appropriate).
