◆ addSLEB128()

void DIEHash::addSLEB128 ( int64_t Value )

◆ addULEB128()

void DIEHash::addULEB128 ( uint64_t Value )

◆ computeCUSignature()

Computes the CU signature.

This is based on the type signature computation given in section 7.27 of the DWARF4 standard.

It is an md5 hash of the flattened description of the DIE with the inclusion of the full CU and all top level CU entities.

Definition at line 399 of file DIEHash.cpp.

References llvm::StringRef::empty().

◆ computeTypeSignature()

Computes the type signature.

This is based on the type signature computation given in section 7.27 of the DWARF4 standard.

It is an md5 hash of the flattened description of the DIE with the inclusion of additional forms not specifically called out in the standard.

◆ hashRawTypeReference()

◆ update()

void llvm::DIEHash::update ( uint8_t Value) inline

Adds.
