Definition RISCVMachineFunctionInfo.h:154

Wrapper class representing virtual and physical registers.

This is a 'vector' (really, a variable-sized array), optimized for the case when the array is small.

void mapOptional(StringRef Key, T &Val)

This is an optimization pass for GlobalISel generic memory operations.

BumpPtrAllocatorImpl<> BumpPtrAllocator

The standard BumpPtrAllocator which just uses the default template parameters.

This struct is a compact representation of a valid (non-zero power of two) alignment.

MachineFunctionInfo - This class can be derived from and used by targets to hold private target-speci...

Targets should override this in a way that mirrors the implementation of llvm::MachineFunctionInfo.

static void mapping(IO &YamlIO, RISCVMachineFunctionInfo &MFI)

Definition RISCVMachineFunctionInfo.h:38

This class should be specialized by any type that needs to be converted to/from a YAML mapping.
