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

BinaryStreamRef is to BinaryStream what ArrayRef is to an Array.

LLVM_ABI Error writeCString(StringRef Str)

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

Definition BinaryStreamWriter.cpp:47

Error writeArray(ArrayRef< T > Array)

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

LLVM_ABI Error writeSLEB128(int64_t Value)

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

Definition BinaryStreamWriter.cpp:41

BinaryStreamWriter()=default

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

Splits the Writer into two Writers at a given offset.

Definition BinaryStreamWriter.cpp:83

LLVM_ABI Error writeStreamRef(BinaryStreamRef Ref)

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

Definition BinaryStreamWriter.cpp:61

LLVM_ABI Error writeBytes(ArrayRef< uint8_t > Buffer)

Write the bytes specified in Buffer to the underlying stream.

Definition BinaryStreamWriter.cpp:28

uint64_t getLength() const

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

LLVM Value Representation.

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

This is an optimization pass for GlobalISel generic memory operations.

ArrayRef< CharT > arrayRefFromStringRef(StringRef Input)

Construct a string ref from an array ref of unsigned chars.

@ 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.
