This code implements a working Just-In-Time binary translator from the
Beta [1] processor to the i386. It supports clock and keyboard
interrupts, and correctly executes lab6.uasm, bench[1-4].uasm, and
litmus.uasm, as well as Lab 8's operating system [2].
This source is canonically available from github at
<http://github.com/nelhage/bemu/>.
It should work on just about any modern Linux or Intel OS X system,
although it's better tested on Linux. I've tested it on Athena and it
works fine there.
To run the self-tests, `make test'; To run the lab8 OS, `make
run-lab8'.
It alsos includes a somewhat hacked version of `uasm' from
http://web.mit.edu/6.004/src/posix-src/uasm/, modified to deal with
relative includes slightly better, and to support arbitrary-sized
ROMs.
