Detailed Description

The string table used for serializing remarks.

This table can be for example serialized in a section to be consumed after the compilation.

Constructor & Destructor Documentation

StringTable() [1/4]

llvm::remarks::StringTable::StringTable ( )

default

StringTable() [2/4]

llvm::remarks::StringTable::StringTable ( const StringTable &  )

delete

Disable copy.

StringTable() [3/4]

llvm::remarks::StringTable::StringTable ( StringTable &&  )

default

Should be movable.

StringTable() [4/4]

StringTable::StringTable

(

const ParsedStringTable &

Other

)

Construct a string table from a ParsedStringTable.

Member Function Documentation

add()

std::pair< unsigned, StringRef > StringTable::add

(

StringRef

Str

)

Add a string to the table. It returns an unique ID of the string.

internalize()

void StringTable::internalize

(

Remark &

R

)

Modify R to use strings from this string table.

If the string table does not contain the strings, it adds them.

operator=() [1/2]

StringTable & llvm::remarks::StringTable::operator= ( const StringTable &  )

delete

operator=() [2/2]

StringTable & llvm::remarks::StringTable::operator= ( StringTable &&  )

default

serialize() [1/2]

std::vector< StringRef > StringTable::serialize

(

)

const

Serialize the string table to a vector.

This allows users to do the actual writing to file/memory/other. The string with the ID == N should be the N-th element in the vector.

Definition at line 65 of file RemarkStringTable.cpp.

serialize() [2/2]

void StringTable::serialize

(

raw_ostream &

OS

)

const

Serialize the string table to a stream.

It is serialized as a little endian uint64 (the size of the table in bytes) followed by a sequence of NULL-terminated strings, where the N-th string is the string with the ID N in the StrTab map.

Definition at line 56 of file RemarkStringTable.cpp.

Member Data Documentation

SerializedSize

size_t llvm::remarks::StringTable::SerializedSize = 0

Total size of the string table when serialized.

Definition at line 41 of file RemarkStringTable.h.

StrTab

StringMap<unsigned, BumpPtrAllocator> llvm::remarks::StringTable::StrTab

The string table containing all the unique strings used in the output.

It maps a string to an unique ID.
