Define "contiki" OS specifier.

[davide]

testcase?

[mlemay-intel]

Added test.

[davide]

I mean, this is OK, but where do you plan to use it?

[davide]

I see, D19852. I'm fine with this going in but please wait for Eric or Chandler for a final sign-off.

[echristo]

This is fine I guess.

Remove isTargetContiki from X86Subtarget.

[echristo]

Still OK. Thanks!
