yann@1365	17	+ * Core file format: The core file is written in such a way that gdb
yann@1365	18	+ * can understand it and provide useful information to the user (under
yann@1365	19	+ * linux we use the `trad-core' bfd). The file contents are as follows:
yann@1365	20	+ *
yann@1365	21	+ * upage: 1 page consisting of a user struct that tells gdb
yann@1365	22	+ * what is present in the file. Directly after this is a
yann@1365	23	+ * copy of the task_struct, which is currently not used by gdb,
yann@1365	24	+ * but it may come in handy at some point. All of the registers
yann@1365	25	+ * are stored as part of the upage. The upage should always be
yann@1365	26	+ * only one page long.
yann@1365	27	+ * data: The data segment follows next. We use current->end_text to
yann@1365	28	+ * current->brk to pick up all of the user variables, plus any memory
yann@1365	29	+ * that may have been sbrk'ed. No attempt is made to determine if a
yann@1365	30	+ * page is demand-zero or if a page is totally unused, we just cover
yann@1365	31	+ * the entire range. All of the addresses are rounded in such a way
yann@1365	32	+ * that an integral number of pages is written.
yann@1365	33	+ * stack: We need the stack information in order to get a meaningful
yann@1365	34	+ * backtrace. We need to write the data from usp to
yann@1365	35	+ * current->start_stack, so we round each of these in order to be able
yann@1365	36	+ * to write an integer number of pages.
