Instruction Selection is the process of translating LLVM code presented to the code generator into target-specific machine instructions. There are several -well-known ways to do this in the literature. In LLVM there are two main forms: -the SelectionDAG based instruction selector framework and an old-style 'simple' -instruction selector, which effectively peephole selects each LLVM instruction -into a series of machine instructions. We recommend that all targets use the -SelectionDAG infrastructure. +well-known ways to do this in the literature. LLVM uses a SelectionDAG based +instruction selector.

Portions of the DAG instruction selector are generated from the target -- 2.34.1
