/* * Core file format: The core file is written in such a way that gdb * can understand it and provide useful information to the user (under * linux we use the `trad-core' bfd). 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.
