- Add generic support for opcodes that are escape bytes used for multi-byte opcodes (such as the 0x0f prefix). Use this to replace the hard-coded 0x0f special case and add support for three-byte opcodes that use the 0x0f38 prefix. - Decode all Intel VMX instructions. invept and invvpid in particular are three-byte opcodes that use the 0x0f38 escape prefix. - Rework how the special 'SDEP' size flag works such that the default instruction name (i_name) is the instruction when the data size prefix (0x66) is not specified, and the alternate name in i_extra is used when the prefix is included. - Add a new 'ADEP' size flag similar to 'SDEP' except that it chooses between i_name and i_extra based on the address size prefix (0x67). Use this to fix the decoding for jrcxz vs jecxz which is determined by the address size prefix, not the operand size prefix. Also, jcxz is not possible in 64-bit mode, but jrcxz is the default instruction for that opcode. - Add support for handling instructions that have a mandatory 'rep' prefix (this means not outputting the 'repe ' prefix until determining if it is used as part of an opcode). Make 'pause' less of a special case this way. - Decode 'cmpxchg16b' and 'cdqe' which are variants of other instructions but with a REX.W prefix. MFC after: 1 month |

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 ``world'' target should only be used in cases where the source tree has not changed from the currently running version. See: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables. 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/doc/en_US.ISO8859-1/books/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.
