I've not tested FastISel on Linux at all, I'm afraid. In theory I'd
expect only minor modifications to be necessary (around global
variable materialisation, if anywhere).

Cheers.

*nod*. That's most of what we needed for ARM as well. Should probably
conditionalize it on os darwin for now until it's tested more with a
command line?

I just wasn't sure if you'd tested it at all there.

I'd almost prefer to leave it in for the bugs to be discovered
(perhaps after some simple tests of our own). ARM went wirthout
FastISel support on Linux for years simply because it was declared
Darwin-only.
