#define LLVM_DUMP_METHOD

Mark debug helper function definitions like dump() that should not be stripped from debug builds.

This file implements a map that provides insertion order iteration.

This file defines the PointerIntPair class.

This file defines the SmallVector class.

Tagged DWARF-like metadata node.

For each inlined instance of a source-level label, keep the corresponding DBG_LABEL instruction.

This class provides interface to collect and use lexical scoping information from machine instruction...

Representation of each machine instruction.

This class implements a map that also provides access to all stored values in a deterministic order.

typename SmallVector< std::pair< InlinedEntity, Entries >, 0 >::const_iterator const_iterator

PointerIntPair - This class implements a pair of a pointer and small integer.

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

StringRef - Represent a constant reference to a string, i.e.

TargetRegisterInfo base class - We assume that the target defines a static array of TargetRegisterDes...

This is an optimization pass for GlobalISel generic memory operations.
