[LLVMdev] Hit a snag while attempting to write a backend - any advice?

Hi Lee,

No worries. I know how annoying it can be trying to fix these
problems. "isBarrier" is the one that usually got me.

The best I know of is include/llvm/Target/Target.td, which contains a
one-line description of each of these flags. Unfortunately it's often
still a little ambiguous, or depends on detailed knowledge of LLVM's
workings.
