base which it adds a single analysis pass to, to instead return the type erased TargetTransformInfo object constructed for that TargetMachine. This removes all of the pass variants for TTI. There is now a single TTI *pass* in the Analysis layer. All of the Analysis <-> Target communication is through the TTI's type erased interface itself. While the diff is large here, it is nothing more that code motion to make types available in a header file for use in a different source file within each target. I've tried to keep all the doxygen comments and file boilerplate in line with this move, but let me know if I missed anything. With this in place, the next step to making TTI work with the new pass manager is to introduce a really simple new-style analysis that produces a TTI object via a callback into this routine on the target machine. Once we have that, we'll have the building blocks necessary to accept a function argument as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@227685 91177308-0d34-0410-b5e6-96231b3b80d8
