The file contents are as 97f30491cSTony Luck * follows: 107f30491cSTony Luck * 117f30491cSTony Luck * upage: 1 page consisting of a user struct that tells gdb 127f30491cSTony Luck * what is present in the file. Directly after this is a 137f30491cSTony Luck * copy of the task_struct, which is currently not used by gdb, 147f30491cSTony Luck * but it may come in handy at some point. All of the registers 157f30491cSTony Luck * are stored as part of the upage. The upage should always be 167f30491cSTony Luck * only one page long. 177f30491cSTony Luck * data: The data segment follows next. We use current->end_text to 187f30491cSTony Luck * current->brk to pick up all of the user variables, plus any memory 197f30491cSTony Luck * that may have been sbrk'ed. No attempt is made to determine if a 207f30491cSTony Luck * page is demand-zero or if a page is totally unused, we just cover 217f30491cSTony Luck * the entire range. All of the addresses are rounded in such a way 227f30491cSTony Luck * that an integral number of pages is written. 237f30491cSTony Luck * stack: We need the stack information in order to get a meaningful 247f30491cSTony Luck * backtrace. We need to write the data from usp to 257f30491cSTony Luck * current->start_stack, so we round each of these in order to be able 267f30491cSTony Luck * to write an integer number of pages. 277f30491cSTony Luck * 287f30491cSTony Luck * Modified 1998, 1999, 2001 297f30491cSTony Luck * David Mosberger-Tang <davidm@hpl.hp.com>, Hewlett-Packard Co 307f30491cSTony Luck */ 317f30491cSTony Luck 327f30491cSTony Luck #include <linux/ptrace.h> 337f30491cSTony Luck #include <linux/types.h> 347f30491cSTony Luck 357f30491cSTony Luck #include <asm/page.h> 367f30491cSTony Luck 377f30491cSTony Luck #define EF_SIZE 3072 /* XXX fix me */ 387f30491cSTony Luck 397f30491cSTony Luck struct user { 407f30491cSTony Luck unsigned long regs[EF_SIZE/8+32]; /* integer and fp regs */ 417f30491cSTony Luck size_t u_tsize; /* text size (pages) */ 427f30491cSTony Luck size_t u_dsize; /* data size (pages) */ 437f30491cSTony Luck size_t u_ssize; /* stack size (pages) */ 447f30491cSTony Luck unsigned long start_code; /* text starting address */ 457f30491cSTony Luck unsigned long start_data; /* data starting address */ 467f30491cSTony Luck unsigned long start_stack; /* stack starting address */ 477f30491cSTony Luck long int signal; /* signal causing core dump */ 487f30491cSTony Luck unsigned long u_ar0; /* help gdb find registers */ 497f30491cSTony Luck unsigned long magic; /* identifies a core file */ 507f30491cSTony Luck char u_comm[32]; /* user command name */ 517f30491cSTony Luck }; 527f30491cSTony Luck 537f30491cSTony Luck #endif /* _ASM_IA64_USER_H */ 54
