...lculation of dominator trees remains unchanged as a template. 3. https://reviews.llvm.org/D83094: Adds a GenericCycleInfo analysis as a first "full" user of the CfgInterface machinery. Unlike LoopInfo, this analysis computes a nesting of both reducible and irreducible loops (based on Havlak (1997)). Why now? ======== The concrete need that prompted this development is a reworking of the control flow lowering in the AMDGPU backend. Part of this rework is a new divergence/uniformity analysis that can be used on both LLVM IR and MachineIR. This analysis has to be able to operate gen...
