Detailed Description

Implementation of the remark serializer using LLVM bitstream.

Constructor & Destructor Documentation

◆ BitstreamRemarkSerializer() [1/2]

BitstreamRemarkSerializer::BitstreamRemarkSerializer	(	raw_ostream &	OS,
		SerializerMode	Mode
	)

Construct a serializer that will create its own string table.

Definition at line 328 of file BitstreamRemarkSerializer.cpp.

References assert(), llvm::remarks::Bitstream, llvm::remarks::RemarkSerializer::Mode, llvm::remarks::Separate, llvm::remarks::SeparateRemarksFile, and llvm::remarks::RemarkSerializer::StrTab.

◆ BitstreamRemarkSerializer() [2/2]

BitstreamRemarkSerializer::BitstreamRemarkSerializer	(	raw_ostream &	OS,
		SerializerMode	Mode,
		StringTable	StrTab
	)

Construct a serializer with a pre-filled string table.

Definition at line 339 of file BitstreamRemarkSerializer.cpp.

Member Function Documentation

◆ classof()

static bool llvm::remarks::BitstreamRemarkSerializer::classof ( const RemarkSerializer * S )

inlinestatic

Definition at line 154 of file BitstreamRemarkSerializer.h.

References llvm::remarks::Bitstream, and S.

◆ emit()

void BitstreamRemarkSerializer::emit ( const Remark & Remark )

overridevirtual

Emit a remark to the stream.

This also emits the metadata associated to the remarks based on the SerializerMode specified at construction. This writes the serialized output to the provided stream.

Implements llvm::remarks::RemarkSerializer.

Definition at line 349 of file BitstreamRemarkSerializer.cpp.

References assert(), llvm::remarks::BitstreamRemarkSerializerHelper::ContainerType, DidSetUp, llvm::remarks::MetaSerializer::emit(), llvm::remarks::BitstreamRemarkSerializerHelper::emitRemarkBlock(), llvm::remarks::BitstreamRemarkSerializerHelper::flushToStream(), Helper, llvm::remarks::RemarkSerializer::OS, llvm::remarks::Standalone, and llvm::remarks::RemarkSerializer::StrTab.

◆ metaSerializer()

std::unique_ptr< MetaSerializer > BitstreamRemarkSerializer::metaSerializer	(	raw_ostream &	OS,
		std::optional< StringRef >	ExternalFilename = `std::nullopt`
	)

overridevirtual

The metadata serializer associated to this remark serializer.

Based on the container type of the current serializer, the container type of the metadata serializer will change.

Implements llvm::remarks::RemarkSerializer.

Definition at line 369 of file BitstreamRemarkSerializer.cpp.

References assert(), llvm::remarks::BitstreamRemarkSerializerHelper::ContainerType, Helper, llvm::remarks::RemarkSerializer::OS, llvm::remarks::SeparateRemarksMeta, llvm::remarks::Standalone, and llvm::remarks::RemarkSerializer::StrTab.

Member Data Documentation

◆ DidSetUp

bool llvm::remarks::BitstreamRemarkSerializer::DidSetUp = false

The file should contain: 1) The block info block that describes how to read the blocks.

2) The metadata block that contains various information about the remarks in the file. 3) A number of remark blocks. We need to set up 1) and 2) first, so that we can emit 3) after. This flag is used to emit the first two blocks only once.
