ArrayRef - Represent a constant reference to an array (0 or more elements consecutively in memory),...

ArrayRef< T > drop_front(size_t N=1) const

Drop the first N elements of the array.

const T & front() const

front - Get the first element.

bool empty() const

empty - Check if the array is empty.

Provides read only access to a subclass of BinaryStream.

void setOffset(uint64_t Off)

Error readArray(ArrayRef< T > &Array, uint32_t NumElements)

Get a reference to a NumElements element array of objects of type T from the underlying stream as if ...

FixedStreamArray is similar to VarStreamArray, except with each record having a fixed-length.

This class consists of common code factored out of the SmallVector class to reduce code duplication b...

void append(ItTy in_start, ItTy in_end)

Add the specified range to the end of the SmallVector.

void push_back(const T &Elt)

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

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

ArrayRef< uint8_t > content() const

static const uint32_t PointerModeShift

static const uint32_t PointerModeMask

PointerMode

Equivalent to CV_ptrmode_e.

@ PointerToMemberFunction

LLVM_ABI bool discoverTypeIndicesInSymbol(const CVSymbol &Symbol, SmallVectorImpl< TiReference > &Refs)

Discover type indices in symbol records.

Definition TypeIndexDiscovery.cpp:502

MethodKind

Part of member attribute flags. (CV_methodprop_e)

CVRecord< TypeLeafKind > CVType

LLVM_ABI void discoverTypeIndices(ArrayRef< uint8_t > RecordData, SmallVectorImpl< TiReference > &Refs)

CVRecord< SymbolKind > CVSymbol

TypeLeafKind

Duplicate copy of the above enum, but using the official CV names.

SymbolKind

Duplicate copy of the above enum, but using the official CV names.

uint32_t read32le(const void *P)

detail::packed_endian_specific_integral< uint32_t, llvm::endianness::little, unaligned > ulittle32_t

This is an optimization pass for GlobalISel generic memory operations.

FunctionAddr VTableAddr Count

@ Ref

The access may reference the value stored in memory.

void cantFail(Error Err, const char *Msg=nullptr)

Report a fatal error if Err is a failure value.
