assert(UImm &&(UImm !=~static_cast< T >(0)) &&"Invalid immediate!")

Provides read only access to a subclass of BinaryStream.

LLVM_ABI Error readCString(StringRef &Dest)

Read a null terminated string from Dest.

void setOffset(uint64_t Off)

uint64_t getLength() const

BinaryStreamRef is to BinaryStream what ArrayRef is to an Array.

Lightweight error class with error context and mandatory checking.

static ErrorSuccess success()

Create a success value.

Tagged union holding either a T or a Error.

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

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

A range adaptor for a pair of iterators.

This provides a very simple, boring adaptor for a begin and end iterator into a range type.

This is an optimization pass for GlobalISel generic memory operations.

iterator_range< T > make_range(T x, T y)

Convenience function for iterating over sub-ranges.

FunctionAddr VTableAddr Count

Error make_error(ArgTs &&... Args)

Make a Error instance representing failure using the given error info type.

void consumeError(Error Err)

Consume a Error without doing anything.
