The file contents * are as follows: * *  upage: 1 page consisting of a user struct that tells gdb *	what is present in the file.  Directly after this is a *	copy of the task_struct, which is currently not used by gdb, *	but it may come in handy at some point.  All of the registers *	are stored as part of the upage.  The upage should always be *	only one page long. *  data: The data segment follows next.  We use current->end_text to *	current->brk to pick up all of the user variables, plus any memory *	that may have been sbrk'ed.  No attempt is made to determine if a *	page is demand-zero or if a page is totally unused, we just cover *	the entire range.  All of the addresses are rounded in such a way *	that an integral number of pages is written. *  stack: We need the stack information in order to get a meaningful *	backtrace.  We need to write the data from usp to *	current->start_stack, so we round each of these in order to be able *	to write an integer number of pages. */struct user {	unsigned long	regs[EF_SIZE/8+32];	/* integer and fp regs */	size_t		u_tsize;		/* text size (pages) */	size_t		u_dsize;		/* data size (pages) */	size_t		u_ssize;		/* stack size (pages) */	unsigned long	start_code;		/* text starting address */	unsigned long	start_data;		/* data starting address */	unsigned long	start_stack;		/* stack starting address */	long int	signal;			/* signal causing core dump */	unsigned long	u_ar0;			/* help gdb find registers */	unsigned long	magic;			/* identifies a core file */	char		u_comm[32];		/* user command name */}; #endif /* _ALPHA_USER_H */
