...optimizations. At what point do those cross the line from being data to being another intermediate representation? I would argue that a good test is whether the intention is whether you lower from one to the next. For example, gcc lowers from GENERIC to GIMPLE and never looks back, Open64 lower VHL to HL to ML to LL to VLL the same way. The SCEV format at least isn't like that, but there is at least one lowering step from the IR to the DAG/MachineInsts that machine-specific CodeGen uses. MCInst may not be an IR on the grounds that it's not intermediate, it's just a direct repr...

Hello Everyone! New to the forums, so hopefully I'm not a nuisance. I just wanted to know where to go (since I heard there were about 5 different intermediate forms for llvm) to find the highest level intermediate form of llvm. I want to be able to get as much information from a front-end as possible. Mainly I need to find out dependencies and control flows, amongst a few other things.
