both Elf_Rel and Elf_Rela types of relocation, so handle them both even though we only have Rel_Rela ATM. We don't handle 32-bit and big-endian variants yet. Support for that is not trivial enough to implement it without any evidence that we ever need it in the near future. For the FPTR relocations, we currently use the fptr_storage used by _reloc() is locore.s. This is in no way a real solution, but for now provides the service we need to get the basics going. A static recursive function lookup_fdesc() is used to find the address of a function in a way that keeps track of the load module so that we can get the correct GP value if we need to construct an OPD (ie there's no OPD yet for the function. For simplicity, we create an OPD for the IPLT relocations as well and simply fill the user provided function descriptor from the OPD. Since the the official descriptors are unique, this has no bad side effects. Note that we ignore the addend for FPTR relocations, but use the addend for IPLT relocations as an offset to the function address. This commit allows us to load and relocate modules and modules appear to work correctly, although we probably need to make sure that we set GP correctly in all cases when we have inter-module calls. This especially applies to assembly coded functions that have cross module calls. |

This is the top level of the FreeBSD source directory. This file was last revised on: $FreeBSD$ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel, the kernel-modules and the contents of /etc. The ``buildkernel'' and ``installkernel'' targets build and install the kernel and the modules (see below). Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel is a somewhat more involved process, documentation for which can be found at: http://www.FreeBSD.org/handbook/kernelconfig.html And in the config(8) man page. Note: If you want to build and install the kernel with the ``buildkernel'' and ``installkernel'' targets, you might need to build world before. More information is available in the handbook. The sample kernel configuration files reside in the sys/<arch>/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file NOTES contains entries and documentation for all possible devices, not just those commonly used. It is the successor of the ancient LINT file, but in contrast to LINT, it is not buildable as a kernel but a pure reference and documentation file.
