SmallPtrSet - This class implements a set which is optimized for holding SmallSize or less elements.

void mapOptional(StringRef Key, T &Val)

#define llvm_unreachable(msg)

Marks that the current location is not supposed to be reachable.

This is an optimization pass for GlobalISel generic memory operations.

auto size(R &&Range, std::enable_if_t< std::is_base_of< std::random_access_iterator_tag, typename std::iterator_traits< decltype(Range.begin())>::iterator_category >::value, void > *=nullptr)

Get the size of a range.

bool LRSpilled

Definition ARMMachineFunctionInfo.h:308

ARMFunctionInfo()=default

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

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

Definition ARMMachineFunctionInfo.h:318

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