Methods

¶llvm::Error checkIntegrity()

Description

Check the integrity of the record.

Declared at: llvm/include/llvm/ProfileData/InstrProfData.inc:391

¶void deserializeTo(llvm::InstrProfRecord& Record,
                   llvm::InstrProfSymtab* SymTab)

Description

Read data from this data and save it to \c Record.

Declared at: llvm/include/llvm/ProfileData/InstrProfData.inc:416

Parameters

llvm::InstrProfRecord& Record

llvm::InstrProfSymtab* SymTab

¶static uint32_t getSize(
    const llvm::InstrProfRecord& Record)

Description

Return the total size in bytes of the on-disk value profile data given the data stored in Record.

Declared at: llvm/include/llvm/ProfileData/InstrProfData.inc:382

Parameters

const llvm::InstrProfRecord& Record

¶uint32_t getSize() const

Description

Return the total size of \c ValueProfileData.

Declared at: llvm/include/llvm/ProfileData/InstrProfData.inc:412

¶static Expected<std::unique_ptr<ValueProfData>>
getValueProfData(
    const unsigned char* SrcBuffer,
    const unsigned char* const SrcBufferEnd,
    support::endianness SrcDataEndianness)

Description

Return a pointer to \c ValueProfileData instance ready to be read. All data in the instance are properly byte swapped. The input data is assumed to be in little endian order.

Declared at: llvm/include/llvm/ProfileData/InstrProfData.inc:398

Parameters

const unsigned char* SrcBuffer

const unsigned char* const SrcBufferEnd

support::endianness SrcDataEndianness

¶static std::unique_ptr<ValueProfData>
serializeFrom(const llvm::InstrProfRecord& Record)

Description

Return a pointer to \c ValueProfData instance ready to be streamed.

Declared at: llvm/include/llvm/ProfileData/InstrProfData.inc:387

Parameters

const llvm::InstrProfRecord& Record

¶void swapBytesFromHost(
    support::endianness Endianness)

Description

Swap byte order from host byte order to \c Endianness order.

Declared at: llvm/include/llvm/ProfileData/InstrProfData.inc:408

Parameters

support::endianness Endianness

¶void swapBytesToHost(
    support::endianness Endianness)

Description

Swap byte order from \c Endianness order to host byte order.

Declared at: llvm/include/llvm/ProfileData/InstrProfData.inc:404

Parameters

support::endianness Endianness
