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

+#
+# This script generates the risugen output for a given
+# list of instructions
+# Then it runs concurrently the master and the apprentice:
+# - the master is started on remote host provided by the
+# environment variable RISU_MASTER
+# - the apprentice is started in a chroot provided by the
+# environment variable RISU_CHROOT
+# Master and apprentice must share a directory, the path
+# of this directory is given by RISU_PATH. The risu files
+# will be searched in this directory.
+# The RISU_ARCH gives the name of the risu patterns file
+# to use.

+# Example:

+# RISU_ARCH=m68k RISU_MASTER=192.168.100.3 \
+# RISU_CHROOT=/chroot/m68k \
