Member Function Documentation

◆ CanLoadImage()

Status lldb_private::wasm::DynamicLoaderWasmDYLD::CanLoadImage ( )

inlineoverridevirtual

Ask if it is ok to try and load or unload an shared library (image).

The dynamic loader often knows when it would be ok to try and load or unload a shared library. This function call allows the dynamic loader plug-ins to check any current dyld state to make sure it is an ok time to load a shared library.

Returns: true if it is currently ok to try and load a shared library into the process, false otherwise.

Implements lldb_private::DynamicLoader.

◆ DidLaunch()

void lldb_private::wasm::DynamicLoaderWasmDYLD::DidLaunch ( )

inlineoverridevirtual

Called after launching a process.

Allow DynamicLoader plug-ins to execute some code after the process has stopped for the first time on launch.

◆ GetStepThroughTrampolinePlan()

ThreadPlanSP DynamicLoaderWasmDYLD::GetStepThroughTrampolinePlan	(	Thread &	thread,
		bool	stop_others
	)

overridevirtual

Provides a plan to step through the dynamic loader trampoline for the current state of thread.

Parameters

[in] stop_others Whether the plan should be set to stop other threads.

Returns: A pointer to the plan (caller owned) or NULL if we are not at such a trampoline.

Implements lldb_private::DynamicLoader.

		lldb::addr_t	link_map_addr,
		lldb::addr_t	base_addr,
		bool	base_addr_is_offset
	)

overridevirtual

Locates or creates a module given by file and updates/loads the resulting module at the virtual base address base_addr.

Note that this calls Target::GetOrCreateModule with notify being false, so it is necessary to call Target::ModulesDidLoad afterwards.
