struct  llvm::InstrAspect
 Legalization is decided based on an instruction's opcode, which type slot we're considering, and what the existing type is. More...
struct  llvm::LegacyLegalizeActionStep
 The result of a query. More...

 This is an optimization pass for GlobalISel generic memory operations.
