template<typename uintty >

void llvm::BitstreamWriter::EmitRecord	(	unsigned	Code,

	)		`[inline]`

EmitRecord - Emit the specified record to the stream, using an abbrev if we have one to compress the output.

template<typename uintty >

void llvm::BitstreamWriter::EmitRecordWithAbbrev	(	unsigned	Abbrev,
		SmallVectorImpl< uintty > &	Vals
	)		`[inline]`

EmitRecordWithAbbrev - Emit a record with the specified abbreviation. Unlike EmitRecord, the code for the record should be included in Vals as the first entry.

template<typename uintty >

void llvm::BitstreamWriter::EmitRecordWithArray	(	unsigned	Abbrev,

EmitRecordWithArray - Just like EmitRecordWithBlob, works with records that end with an array.

template<typename uintty >

void llvm::BitstreamWriter::EmitRecordWithBlob	(	unsigned	Abbrev,
		SmallVectorImpl< uintty > &	Vals,
		StringRef	Blob
	)		`[inline]`

EmitRecordWithBlob - Emit the specified record to the stream, using an abbrev that includes a blob at the end. The blob data to emit is specified by the pointer and length specified at the end. In contrast to EmitRecord, this routine expects that the first entry in Vals is the code of the record.
