++ *
++ * 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, NOT the osf-core). 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.
