[LLVMdev] [LLVMDev] Is it possible to implement target specific optimizations which can be applied after instruction selection or later?

[Evan Cheng]

Yes. There are lots of examples of this. For example ARM target has a number of specific optimization passes. See ARMTargetMachine.cpp addPreEmitPass() etc. for examples of how they are added to codegen pass manager.
