12928 + * Core file format: The core file is written in such a way that gdb
12929 + * can understand it and provide useful information to the user (under
12930 + * linux we use the `trad-core' bfd, NOT the osf-core). The file contents
12931 + * are as follows:
12932 + *
12933 + * upage: 1 page consisting of a user struct that tells gdb
12934 + * what is present in the file. Directly after this is a
12935 + * copy of the task_struct, which is currently not used by gdb,
12936 + * but it may come in handy at some point. All of the registers
12937 + * are stored as part of the upage. The upage should always be
12938 + * only one page long.
12939 + * data: The data segment follows next. We use current->end_text to
12940 + * current->brk to pick up all of the user variables, plus any memory
12941 + * that may have been sbrk'ed. No attempt is made to determine if a
12942 + * page is demand-zero or if a page is totally unused, we just cover
12943 + * the entire range. All of the addresses are rounded in such a way
12944 + * that an integral number of pages is written.
12945 + * stack: We need the stack information in order to get a meaningful
12946 + * backtrace. We need to write the data from usp to
12947 + * current->start_stack, so we round each of these in order to be able
12948 + * to write an integer number of pages.
