It does make the TargetMachine -> TargetIRAnalysis path less abstract, but given that all targets have the same pattern of instantiating a TargetIRAnalysis with a Function->TargetTransformInfo hook, the abstraction does not seem particularly useful. I might do even a simpler form of the patch though -- instead of returning a function pointer f...

Hi all, I'd like to be able to use TargetTransformInfo to make architecture specific code generation decisions from the XLA LLVM IR emitter[0]. However, we don't have a great way to do this today -- TargetTransformInfo is wrapped in a TargetIRAnalysis and getting the TargetTransformInfo out of it requires something like: FunctionAnalysisManager DummyFAM; TTI = TIRA.run(F, DummyFAM); return *TTI; which isn't ideal. Given that all in-tree backends have a factory function to directly construct a TargetTransformInfo implementation anyw...

With D21921 and a couple other pending patches, we now have the full LTO pipeline converted to the new PM. I was trying it out on test-suite and SPEC2006. Yay! This email is about one issue that I ran into testing the pipeline on test-suite. The issue arose in the wild as an interaction between lcssa and gvn. But the issue is extremely general. What happened is that BasicAA uses
