The existing pattern support is useful but it does get a little
tedious when faced with large groups of instructions. This introduces
the concept of a @GroupName which can be sprinkled in the risu
definition and is attached to all instructions following its
definition until the next group or an empty group "@" is specified.
It can be combined with the existing pattern support to do things
like:
./risugen --group AdvSIMDAcrossVector --not-pattern ".*_RES" aarch64.risu foo.bin
Multiple groups will further restrict the set, so for example:
./risugen --group v8.2,Cryptographic aarch64.risu v8.2-crypto.bin

Useful for accessing APIs that are still brewing, e.g:
CROSS_PREFIX=aarch64-linux-gnu- \
CPPFLAGS=-I/home/alex/lsrc/qemu/risu.git/sve-headers/include \
../configure

We also include the an Emacs .dir-locals (as per QEMU) that enforces
this layout.

Add notes to the README about support for separate build directories

This expect script will generate the .out file and then
start the apprentice in a chroot and the master on the reference
hardware. The list of patterns is given on the command line.
As my reference system is very slow, ssh can take more than 2 minutes,
this script starts a ssh and a chroot once, and interacts with
them to run the list of instruction patterns given on the command line.
Some environment variables define the test environment:
- RISU_ARCH: the pattern file used will be $RISU_ARCH.risu
- RISU_MASTER: the IP address or name of the reference hardware (for ssh)
- RISU_CHROOT: the path of the QEMU chroot to start the apprentice
- RISU_PATH: the path, common to master and apprentice (you can use NFS),
where the risu files are stored (binaries and data).
Example:
$ RISU_ARCH=m68k RISU_MASTER=q800 \
RISU_CHROOT=/var/lib/lxc/virtm68k-etch-m68k/rootfs \
RISU_PATH=/nfs/home/laurent/q800/risu \
./automatic-run ASx ADD AND OR EOR

It is possible to build statically with some limitations on the use of

The build process for risu is a bit more complex now we have
a configure script, so describe it in the README.

Document the new 'memory' block syntax used to specify the memory
accessed by a load or store instruction.

Document the .risu file format in the README, rather than in
three duplicate comments in risugen, arm.risu and thumb.risu.
