[LLVMdev] llvm backend tutorial

[Mikael Lyngvig]

I was wondering if this shouldn't somehow find its way into the official
LLVM documentation?  It certainly seems to qualify to become official
documentation in my eyes.  Nearly any LLVM backend writer out there should
be able to benefit from reading about your experiences, I'd think.

I know it is not as generic and abstract as what the LLVM dev list seems to
prefer, but I personally find that the more concrete and based on actual
experience a document is, the better the reader's ability to understand
what's going on.

The only thing is that you might not want to go through the process of a
peer review.  That will likely add much work to what you have already
accomplished.
