Auxiliary table entries

An auxiliary table entry of a symbol contains the same number of bytes as the symbol table entry. However, unlike symbol table entries, the format of an auxiliary table entry of a symbol depends on its type and storage class. They are summarized in ``Auxiliary symbol table entries''.

Auxiliary symbol table entries

    Type Entry  
Storage _ Auxiliary Name
Class d1 typ Entry Format  
.file C_FILE DT_NON T_NULL file name
.text, .data, C_STAT DT_NON T_NULL section
.bss        
tagname C_STRTAG DT_NON T_NULL tag name
  C_UNTAG      
  C_ENTAG      
.eos C_EOS DT_NON T_NULL end of structure
fcname C_EXT DT_FCN (Note 1) function
  C_STAT      
  C_WEAKEXT      
arrname (Note 2) DT_ARY (Note 1) array
.bb, .eb C_BLOCK DT_NON T_NULL beginning and end of block
.bf, .ef C_FCN DT_NON T_NULL beginning and end of function
name related to structure, union, enumeration (Note 2) DT_PTR, DT_ARR, DT_NON T_STRUCT, T_UNION, T_ENUM name related to structure, union, enumeration
Notes to ``Auxiliary symbol table entries'':
1. Any except T_MOE.
2. C_AUTO, C_STAT, C_MOS, C_MOU, C_TPDEF.

In ``Auxiliary symbol table entries'', tagname means any symbol name including the special symbol .xfake, and fcname and arrname represent any symbol name for a function or an array respectively. Any symbol that satisfies more than one condition in ``Auxiliary symbol table entries'' should have a union format in its auxiliary entry.


NOTE: It is a mistake to assume how many auxiliary entries are associated with any given symbol table entry. This information is available and should be obtained from the n_numaux field in the symbol table.
