Member Function Documentation

◆ CGM()

CodeGenModule & CodeGenerator::CGM ( )

Return an opaque reference to the CodeGenModule object, which can be used in various secondary APIs.

It is valid as long as the CodeGenerator exists.

Definition at line 328 of file ModuleBuilder.cpp.

References CGM().

Referenced by CGM().

◆ GetAddrOfGlobal()

llvm::Constant * CodeGenerator::GetAddrOfGlobal ( GlobalDecl  decl,
bool  isForDefinition 
)

Return the LLVM address of the given global entity.

Parameters
isForDefinitionIf true, the caller intends to define the entity; the object returned will be an llvm::GlobalValue of some sort. If false, the caller just intends to use the entity; the object returned may be any sort of constant value, and the code generator will schedule the entity for emission if a definition has been registered with this code generator.

Definition at line 352 of file ModuleBuilder.cpp.

References GetAddrOfGlobal().

◆ getCGDebugInfo()

CGDebugInfo * CodeGenerator::getCGDebugInfo ( )

Return debug info code generator.

Definition at line 340 of file ModuleBuilder.cpp.

References getCGDebugInfo().

Referenced by getCGDebugInfo(), clang::MacroPPCallbacks::MacroDefined(), and clang::MacroPPCallbacks::MacroUndefined().

◆ GetDeclForMangledName()

const Decl * CodeGenerator::GetDeclForMangledName ( llvm::StringRef  MangledName)

Given a mangled name, return a declaration which mangles that way which has been added to this code generator via a Handle method.

This may return null if there was no matching declaration.

Definition at line 344 of file ModuleBuilder.cpp.

References GetDeclForMangledName().

Referenced by GetDeclForMangledName().

◆ GetMangledName()

llvm::StringRef CodeGenerator::GetMangledName ( GlobalDecl  GD)

Given a global declaration, return a mangled name for this declaration which has been added to this code generator via a Handle method.

Definition at line 348 of file ModuleBuilder.cpp.

References GetMangledName().

Referenced by GetMangledName(), and clang::IncrementalParser::GetMangledName().

◆ GetModule()

llvm::Module * CodeGenerator::GetModule ( )

Return the module that this code generator is building into.

This may return null after HandleTranslationUnit is called; this signifies that there was an error generating code. A diagnostic will have been generated in this case, and the module will be deleted.

It will also return null if the module is released.

Definition at line 332 of file ModuleBuilder.cpp.

References GetModule().

Referenced by GetModule().

◆ ReleaseModule()

llvm::Module * CodeGenerator::ReleaseModule ( )

Release ownership of the module to the caller.

It is illegal to call methods other than GetModule on the CodeGenerator after releasing its module.

Definition at line 336 of file ModuleBuilder.cpp.

References ReleaseModule().

Referenced by ReleaseModule().

◆ StartModule()

llvm::Module * CodeGenerator::StartModule ( llvm::StringRef  ModuleName,
llvm::LLVMContext &  C 
)

Create a new llvm::Module after calling HandleTranslationUnit.

This enable codegen in interactive processing environments.
