size_t size() const

size - Get the array size.

Provides read only access to a subclass of BinaryStream.

uint64_t bytesRemaining() const

Error readLongestContiguousChunk(ArrayRef< uint8_t > &Buffer)

Read as much as possible from the underlying string at the current offset without invoking a copy,...

RefType drop_front(uint64_t N) const

Return a new BinaryStreamRef with the first N elements removed.

BinaryStreamRef is to BinaryStream what ArrayRef is to an Array.

Provides write only access to a subclass of WritableBinaryStream.

Error writeCString(StringRef Str)

Write the string Str to the underlying stream followed by a null terminator.

Error writeArray(ArrayRef< T > Array)

Writes an array of objects of type T to the underlying stream, as if by using memcpy.

Error writeSLEB128(int64_t Value)

Write the unsigned integer Value to the underlying stream using ULEB128 encoding.

BinaryStreamWriter()=default

std::pair< BinaryStreamWriter, BinaryStreamWriter > split(uint64_t Off) const

Splits the Writer into two Writers at a given offset.

Error writeStreamRef(BinaryStreamRef Ref)

Efficiently reads all data from Ref, and writes it to this stream.

Error writeBytes(ArrayRef< uint8_t > Buffer)

Write the bytes specified in Buffer to the underlying stream.

uint64_t getLength() const

Error writeFixedString(StringRef Str)

Write the string Str to the underlying stream without a null terminator.

Error writeULEB128(uint64_t Value)

Write the unsigned integer Value to the underlying stream using ULEB128 encoding.

WritableBinaryStreamRef Stream

Error writeObject(const T &Obj)

Writes the object Obj to the underlying stream, as if by using memcpy.

Error padToAlignment(uint32_t Align)

Lightweight error class with error context and mandatory checking.

static ErrorSuccess success()

Create a success value.

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

LLVM Value Representation.

Error writeBytes(uint64_t Offset, ArrayRef< uint8_t > Data) const

Given an Offset into this WritableBinaryStreamRef and some input data, writes the data to the underly...

A BinaryStream which can be read from as well as written to.

This is an optimization pass for GlobalISel generic memory operations.

@ Ref

The access may reference the value stored in memory.

@ First

Helpers to iterate all locations in the MemoryEffectsBase class.

uint64_t alignTo(uint64_t Size, Align A)

Returns a multiple of A needed to store Size bytes.

unsigned encodeSLEB128(int64_t Value, raw_ostream &OS, unsigned PadTo=0)

Utility function to encode a SLEB128 value to an output stream.

unsigned encodeULEB128(uint64_t Value, raw_ostream &OS, unsigned PadTo=0)

Utility function to encode a ULEB128 value to an output stream.

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