static GCRegistry::Add< ErlangGC > A("erlang", "erlang-compatible garbage collector")

This file defines the DenseSet and SmallDenseSet classes.

This is an important base class in LLVM.

A parsed version of the target data layout string in and methods for querying it.

Implements a dense probed hash-table based set.

FoldingSetNodeID - This class is used to gather all the unique data bits of a node.

union llvm::MachineConstantPoolEntry::@004270020304201266316354007027341142157160323045 Val

The constant itself.

bool needsRelocation() const

This method classifies the entry according to whether or not it may generate a relocation entry.

bool isMachineConstantPoolEntry() const

isMachineConstantPoolEntry - Return true if the MachineConstantPoolEntry is indeed a target specific ...

Align Alignment

The required alignment for this entry.

Abstract base class for all machine specific constantpool value subclasses.

void dump() const

dump - Call print(cerr) to be called from the debugger.

MachineConstantPool(const DataLayout &DL)

The only constructor.

Definition MachineConstantPool.h:128

Align getConstantPoolAlign() const

Return the alignment required by the whole constant pool, of which the first element must be aligned.

const std::vector< MachineConstantPoolEntry > & getConstants() const

Definition MachineConstantPool.h:145

void print(raw_ostream &OS) const

print - Used by the MachineFunction printer to print information about constant pool objects.

bool isEmpty() const

isEmpty - Return true if this constant pool contains no constants.

Definition MachineConstantPool.h:143

unsigned getConstantPoolIndex(const Constant *C, Align Alignment)

getConstantPoolIndex - Create a new entry in the constant pool or return an existing one.

SectionKind - This is a simple POD value that classifies the properties of a section.

The instances of the Type class are immutable: once they are created, they are never changed.

This class implements an extremely fast bulk output stream that can only output to a stream.

unsigned ID

LLVM IR allows to use arbitrary numbers as calling convention identifiers.

@ C

The default llvm calling convention, compatible with C.

This is an optimization pass for GlobalISel generic memory operations.

raw_ostream & operator<<(raw_ostream &OS, const APFixedPoint &FX)

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