class NonRelocatableStringpool

Declaration

class NonRelocatableStringpool { /* full declaration omitted */ };

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.

Declared at: llvm/include/llvm/CodeGen/NonRelocatableStringpool.h:23

Method Overview

• public NonRelocatableStringpool(std::function<StringRef (StringRef)> Translator = nullptr, bool PutEmptyString = false)
• public std::vector<DwarfStringPoolEntryRef> getEntriesForEmission() const
• public llvm::DwarfStringPoolEntryRef getEntry(llvm::StringRef S)
• public uint64_t getSize()
• public uint32_t getStringOffset(llvm::StringRef S)
• public llvm::StringRef internString(llvm::StringRef S)

Methods

¶NonRelocatableStringpool(
    std::function<StringRef(StringRef)>
        Translator = nullptr,
    bool PutEmptyString = false)

Declared at: llvm/include/llvm/CodeGen/NonRelocatableStringpool.h:30

Parameters

std::function<StringRef(StringRef)> Translator = nullptr

bool PutEmptyString = false

¶std::vector<DwarfStringPoolEntryRef>
getEntriesForEmission() const

Description

Return the list of strings to be emitted. This does not contain the strings which were added via internString only.

Declared at: llvm/include/llvm/CodeGen/NonRelocatableStringpool.h:56

¶llvm::DwarfStringPoolEntryRef getEntry(
    llvm::StringRef S)

Declared at: llvm/include/llvm/CodeGen/NonRelocatableStringpool.h:38

Parameters

llvm::StringRef S

¶uint64_t getSize()

Declared at: llvm/include/llvm/CodeGen/NonRelocatableStringpool.h:52

¶uint32_t getStringOffset(llvm::StringRef S)

Description

Get the offset of string \p S in the string table. This can insert a new element or return the offset of a pre-existing one.

Declared at: llvm/include/llvm/CodeGen/NonRelocatableStringpool.h:42

Parameters

llvm::StringRef S

¶llvm::StringRef internString(llvm::StringRef S)

Description

Get permanent storage for \p S (but do not necessarily emit \p S in the output section). A latter call to getStringOffset() with the same string will chain it though.

Declared at: llvm/include/llvm/CodeGen/NonRelocatableStringpool.h:50

Parameters

llvm::StringRef S

Returns

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