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.
