class IncrementalParser

Declaration

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

Description

Provides support for incremental compilation. Keeps track of the state changes between the subsequent incremental input.

Declared at: clang/lib/Interpreter/IncrementalParser.h:39

Member Variables

private std::unique_ptr<IncrementalAction> Act

Long-lived, incremental parsing action.

private std::unique_ptr<CompilerInstance> CI

Compiler instance performing the incremental compilation.

private std::unique_ptr<Parser> P

Parser.

private clang::ASTConsumer* Consumer = nullptr

Consumer to process the produced top level decls. Owned by Act.

private unsigned int InputCount = 0

Counts the number of direct user input lines that have been parsed.

private std::list<PartialTranslationUnit> PTUs

List containing every information about every incrementally parsed piece of code.

Methods

¶void CleanUpPTU(
    clang::PartialTranslationUnit& PTU)

Declared at: clang/lib/Interpreter/IncrementalParser.h:75

Parameters

clang::PartialTranslationUnit& PTU

¶llvm::StringRef GetMangledName(
    clang::GlobalDecl GD) const

Description

Uses the CodeGenModule mangled name cache and avoids recomputing.

Declared at: clang/lib/Interpreter/IncrementalParser.h:73

Parameters

clang::GlobalDecl GD

Returns

the mangled name of a \c GD.

¶IncrementalParser(
    std::unique_ptr<CompilerInstance> Instance,
    llvm::LLVMContext& LLVMCtx,
    llvm::Error& Err)

Declared at: clang/lib/Interpreter/IncrementalParser.h:60

Parameters

std::unique_ptr<CompilerInstance> Instance

llvm::LLVMContext& LLVMCtx

llvm::Error& Err

¶llvm::Expected<PartialTranslationUnit&> Parse(
    llvm::StringRef Input)

Description

Parses incremental input by creating an in-memory file.

Declared at: clang/lib/Interpreter/IncrementalParser.h:69

Parameters

llvm::StringRef Input

Returns

a \c PartialTranslationUnit which holds information about the\c TranslationUnitDecl and \c llvm::Module corresponding to the input.
