 7.1 Symbol Table Format
 =======================
 
 Each time the assembler encounters a stab directive, it puts each field
 of the stab into a corresponding field in a symbol table entry of its
 output file.  If the stab contains a string field, the symbol table
 entry for that stab points to a string table entry containing the
 string data from the stab.  Assembler labels become relocatable
 addresses.  Symbol table entries in a.out have the format:
 
      struct internal_nlist {
        unsigned long n_strx;         /* index into string table of name */
        unsigned char n_type;         /* type of symbol */
        unsigned char n_other;        /* misc info (usually empty) */
        unsigned short n_desc;        /* description field */
        bfd_vma n_value;              /* value of symbol */
      };
 
    If the stab has a string, the `n_strx' field holds the offset in
 bytes of the string within the string table.  The string is terminated
 by a NUL character.  If the stab lacks a string (for example, it was
 produced by a `.stabn' or `.stabd' directive), the `n_strx' field is
 zero.
 
    Symbol table entries with `n_type' field values greater than 0x1f
 originated as stabs generated by the compiler (with one random
 exception).  The other entries were placed in the symbol table of the
 executable by the assembler or the linker.
