-+ * 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.
