class InstrProfReaderItaniumRemapper

Declaration

template <typename HashTableImpl>
class InstrProfReaderItaniumRemapper : public InstrProfReaderRemapper { /* full declaration omitted */ };

Description

A remapper that applies remappings based on a symbol remapping file.

Declared at: llvm/lib/ProfileData/InstrProfReader.cpp:765

Inherits from: InstrProfReaderRemapper

Templates

HashTableImpl

Member Variables

private std::unique_ptr<MemoryBuffer> RemapBuffer

The memory buffer containing the remapping configuration. Remappings holds pointers into this buffer.

private llvm::SymbolRemappingReader Remappings

The mangling remapper.

private DenseMap<SymbolRemappingReader::Key, llvm::StringRef> MappedNames

Mapping from mangled name keys to the name used for the key in the profile data. FIXME: Can we store a location within the on-disk hash table instead of redoing lookup?

private InstrProfReaderIndex<HashTableImpl>& Underlying

The real profile data reader.

Method Overview

• public InstrProfReaderItaniumRemapper<HashTableImpl>(std::unique_ptr<MemoryBuffer> RemapBuffer, InstrProfReaderIndex<HashTableImpl> & Underlying)
• public static llvm::StringRef extractName(llvm::StringRef Name)

• public llvm::Error populateRemappings()
• public static void reconstituteName(llvm::StringRef OrigName, llvm::StringRef ExtractedName, llvm::StringRef Replacement, SmallVectorImpl<char> & Out)

Inherited from InstrProfReaderRemapper:

• public getRecords
• public populateRemappings
