Lightweight arrays that are backed by an arbitrary BinaryStream.

if(auto Err=PB.parsePassPipeline(MPM, Passes)) return wrap(std MPM run * Mod

Provides read only access to a subclass of BinaryStream.

LLVM_ABI Error readSubstream(BinarySubstreamRef &Ref, uint32_t Length)

Read Length bytes from the underlying stream into Ref.

Error readInteger(T &Dest)

Read an integer of the specified endianness into Dest and update the stream's offset.

uint64_t bytesRemaining() const

void setOffset(uint64_t Off)

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.

A Module instance is used to store all the information related to an LLVM module.

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.

VarStreamArray< CVSymbol > CVSymbolArray

CVRecord< SymbolKind > CVSymbol

LLVM_ABI CVSymbolArray limitSymbolArrayToScope(const CVSymbolArray &Symbols, uint32_t ScopeBegin)

const uint16_t kInvalidStreamIndex

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.

Error make_error(ArgTs &&... Args)

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

@ Mod

The access may modify the value stored in memory.

OutputIt move(R &&Range, OutputIt Out)

Provide wrappers to std::move which take ranges instead of having to pass begin/end explicitly.

Implement std::hash so that hash_code can be used in STL containers.
