Detailed Description

A string table that doesn't need relocations.

Use this class when a string table doesn't need relocations. This class provides this ability by just associating offsets with strings.

MapTy

using llvm::NonRelocatableStringpool::MapTy = StringMap<DwarfStringPoolEntry, BumpPtrAllocator>

Entries are stored into the StringMap and simply linked together through the second element of this pair in order to keep track of insertion order.

getEntriesForEmission()

std::vector< DwarfStringPoolEntryRef > llvm::NonRelocatableStringpool::getEntriesForEmission

(

)

const

Return the list of strings to be emitted.

This does not contain the strings which were added via internString only.

getStringOffset()

uint64_t llvm::NonRelocatableStringpool::getStringOffset ( StringRef  S )

inline

Get the offset of string S in the string table.

This can insert a new element or return the offset of a pre-existing one.

internString()

StringRef llvm::NonRelocatableStringpool::internString

(

StringRef

S

)

Get permanent storage for S (but do not necessarily emit S in the output section).

A latter call to getStringOffset() with the same string will chain it though.

Returns

The StringRef that points to permanent storage to use in place of S.
