Member Function Documentation

◆ AddModule()

virtual bool lldb_private::ClangModulesDeclVendor::AddModule	(	const SourceModule &	module,
		ModuleVector *	exported_modules,
		Stream &	error_stream
	)

pure virtual

Add a module to the list of modules to search.

Parameters

[in]	module	The path to the exact module to be loaded. E.g., if the desired module is std.io, then this should be { "std", "io" }.
[in]	exported_modules	If non-NULL, a pointer to a vector to populate with the ID of every module that is re-exported by the specified module.
[in]	error_stream	A stream to populate with the output of the Clang parser when it tries to load the module.

Returns: True if the module could be loaded; false if not. If the compiler encountered a fatal error during a previous module load, then this will always return false for this ModuleImporter.

◆ AddModulesForCompileUnit()

virtual bool lldb_private::ClangModulesDeclVendor::AddModulesForCompileUnit	(	CompileUnit &	cu,
		ModuleVector &	exported_modules,
		Stream &	error_stream
	)

pure virtual

Add all modules referred to in a given compilation unit to the list of modules to search.

Parameters

[in]	cu	The compilation unit to scan for imported modules.
[in]	exported_modules	A vector to populate with the ID of each module loaded (directly and via re-exports) in this way.
[in]	error_stream	A stream to populate with the output of the Clang parser when it tries to load the modules.

Returns: True if all modules referred to by the compilation unit could be loaded; false if one could not be loaded. If the compiler encountered a fatal error during a previous module load, then this will always return false for this ModuleImporter.

◆ ForEachMacro()

virtual void lldb_private::ClangModulesDeclVendor::ForEachMacro	(	const ModuleVector &	modules,
		std::function< bool(llvm::StringRef, llvm::StringRef)>	handler
	)

pure virtual

Enumerate all the macros that are defined by a given set of modules that are already imported.

Parameters

[in]	modules	The unique IDs for all modules to query. Later modules have higher priority, just as if you @imported them in that order. This matters if module A #defines a macro and module B #undefs it.
[in]	handler	A function to call with the identifier of this macro and the text of each #define (including the #define directive). #undef directives are not included; we simply elide any corresponding #define. If this function returns true, we stop the iteration immediately.

◆ LanguageSupportsClangModules()

bool ClangModulesDeclVendor::LanguageSupportsClangModules ( lldb::LanguageType language )

static

Query whether Clang supports modules for a particular language.

LLDB uses this to decide whether to try to find the modules loaded by a given compile unit.

Parameters

[in] language The language to query for.

Returns: True if Clang has modules for the given language.
