Subject: Strange things in coff.h
Content-Type: text/plain; charset=us-ascii
Content-Transfer-Encoding: 7bit

While developing DLL lib i've discovered a strange thing in
 file include/coff.h.
 There is cut out from coff.h and my comments started with ==>
=================================================================
#define N_BTMASK	(0xf)

==> Remember that value of N_BTMASK : it is 0xf

#define N_TMASK		(0x30)
#define N_BTSHFT	(4)
#define N_TSHIFT	(2)

==> Skipped a little

/*
 * Type of a symbol, in low N bits of the word
 */
#define T_NULL		0
#define T_VOID		1	/* function argument (only used by compiler) */
#define T_CHAR		2	/* character		*/
#define T_SHORT		3	/* short integer	*/

==> Skipped a little

#define T_USHORT	13	/* unsigned short	*/
#define T_UINT		14	/* unsigned integer	*/
#define T_ULONG		15	/* unsigned long	*/
#define T_LNGDBL	16	/* long double		*/

==> Do u still remember value of N_BTMASK ? ;) (it is 0xf)
==> Now look at next #define and at previous #define. Do u see ?

#define BTYPE(x)	((x) & N_BTMASK)

==> I wonder if T_LNGDBL can ever appear in SYMENT.e_type field.
==> Or I'm missing something ?
===================================================================

							Sincerely yours, Ilya
