Andrew Turner 8657387683 Work around a bug in QEMU when loading data with a load pair instruction
where the source register is also the first destination register.

If this is the case, and we raise an exception in the middle of the
instruction, for example the load is across two pages and the second page
isn't mapped, QEMU will have overwritten the address with invalid data.

This is a valid behaviour in most cases, with the exception of when a
destination register is also use in address generation. As such switch
the order of the registers to ensure the address register is second so it
will be written to second, after any exceptions have happened.

This has been acknowledged in upstream QEMU, however as the workaround is
simple also handle it here.

FreeBSD Source:

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. See build(7) and 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. See build(7), config(8), and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html for more information.

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 kernel configuration files reside in the sys/<arch>/conf sub-directory. GENERIC is the default configuration used in release builds. NOTES contains entries and documentation for all possible devices, not just those commonly used.
