[LLVMdev] Back ends for instructional use?

[Joe Abbey]

I can confirm that QEMU works for Linux ARM. 

We use Debian armel in-house for Linux Arm testing.

We recently also purchased Beagleboards which are a low-cost way to get an ARM development environment.

I'd like to use something that has a stable back end, so that the students can use the selector, probably without changes, and do a project on register allocation and stack layout.  We don't have MIPS or ARM hardware (other than possibly a few donated Android phones to play with), so a simulator like Spim will be essential.
