// This pass performs loop invariant code motion on machine instructions. We
|

// attempt to remove as much code from the body of a loop as possible.

// This pass does not attempt to throttle itself to limit register pressure.
|
||||
// The register allocation phases are expected to perform rematerialization
|
||||
// to recover when register pressure is high.

|

// This pass is not intended to be a replacement or a complete alternative
|
||||
// for the LLVM-IR-level LICM pass. It is only designed to hoist simple
|
||||
// constructs that are not exposed before lowering and instruction selection.
