^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 83) can understand it and provide useful information to the user (under
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 84) linux we use the 'trad-core' bfd). There are quite a number of
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 85) obstacles to being able to view the contents of the floating point
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 86) registers, and until these are solved you will not be able to view the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 87) contents of them. Actually, you can read in the core file and look at
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 88) the contents of the user struct to find out what the floating point
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 89) registers contain.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 90) The actual file contents are as follows:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 91) UPAGE: 1 page consisting of a user struct that tells gdb what is present
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 92) in the file. Directly after this is a copy of the task_struct, which
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 93) is currently not used by gdb, but it may come in useful at some point.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 94) All of the registers are stored as part of the upage. The upage should
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 95) always be only one page.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 96) DATA: The data area is stored. We use current->end_text to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 97) current->brk to pick up all of the user variables, plus any memory
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 98) that may have been malloced. No attempt is made to determine if a page
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 99) is demand-zero or if a page is totally unused, we just cover the entire
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 100) range. All of the addresses are rounded in such a way that an integral
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 101) number of pages is written.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 102) STACK: We need the stack information in order to get a meaningful
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 103) backtrace. We need to write the data from (esp) to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 104) current->start_stack, so we round each of these off in order to be able
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 105) to write an integer number of pages.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 106) The minimum core file size is 3 pages, or 12288 bytes.
