AddClangModuleCompilationOptions()

void Platform::AddClangModuleCompilationOptions ( Target *  target, std::vector< std::string > &  options  )

virtual

Reimplemented in PlatformAppleSimulator, PlatformMacOSX, and PlatformRemoteDarwinDevice.

Definition at line 520 of file Platform.cpp.

Attach()

virtual lldb::ProcessSP lldb_private::Platform::Attach ( ProcessAttachInfo &  attach_info, Debugger &  debugger, Target *  target, Status &  error  )

pure virtual

Attach to an existing process using a process ID.

Each platform subclass needs to implement this function and attempt to attach to the process with the process ID of pid. The platform subclass should return an appropriate ProcessSP subclass that is attached to the process, or an empty shared pointer with an appropriate error.

Returns

An appropriate ProcessSP containing a valid shared pointer to the default Process subclass for the platform that is attached to the process, or an empty shared pointer with an appropriate error fill into the error object.

Implemented in lldb_private::platform_gdb_server::PlatformRemoteGDBServer, lldb_private::PlatformWindows, and PlatformPOSIX.

CalculateTrapHandlerSymbolNames()

virtual void lldb_private::Platform::CalculateTrapHandlerSymbolNames ( )

protectedpure virtual

Ask the Platform subclass to fill in the list of trap handler names.

For most Unix user process environments, this will be a single function name, _sigtramp. More specialized environments may have additional handler names. The unwinder code needs to know when a trap handler is on the stack because the unwind rules for the frame that caused the trap are different.

The base class Platform ivar m_trap_handlers should be updated by the Platform subclass when this method is called. If there are no predefined trap handlers, this method may be a no-op.

Implemented in lldb_private::platform_gdb_server::PlatformRemoteGDBServer, PlatformDarwin, lldb_private::PlatformWindows, PlatformPOSIX, lldb_private::platform_linux::PlatformLinux, lldb_private::platform_netbsd::PlatformNetBSD, lldb_private::platform_freebsd::PlatformFreeBSD, and lldb_private::platform_openbsd::PlatformOpenBSD.

inlinevirtual

Not all platforms will support debugging a process by spawning somehow halted for a debugger (specified using the "eLaunchFlagDebug" launch flag) and then attaching.

Gather all of crash informations into a structured data dictionary.

If the platform have a crashed process with crash information entries, gather all the entries into an structured data dictionary or return a nullptr. This dictionary is generic and extensible, as it contains an array for each different type of crash information.

Parameters

[in]

process

The crashed process.

Returns

A structured data dictionary containing at each entry, the crash information type as the entry key and the matching an array as the entry value. nullptr if not implemented or if the process has no crash information entry. error if an error occured.

FindProcesses()

uint32_t Platform::FindProcesses ( const ProcessInstanceInfoMatch &  match_info, ProcessInstanceInfoList &  proc_infos  )

virtual

Attach to an existing process by process name.

This function is not meant to be overridden by Process subclasses. It will first call Process::WillAttach (const char *) and if that returns true, Process::DoAttach (const char *) will be called to actually do the attach. If DoAttach returns true, then Process::DidAttach() will be called.

Parameters

[in]

process_name

A process name to match against the current process list.

Returns

Returns pid if attaching was successful, or LLDB_INVALID_PROCESS_ID if attaching fails.

GetFileWithUUID()

Locate a file for a platform.

The default implementation of this function will return the same file patch in local_file as was in platform_file.

Parameters

[in]	platform_file	The platform file path to locate and cache locally.
[in]	uuid_ptr	If we know the exact UUID of the file we are looking for, it can be specified. If it is not specified, we might now know the exact file. The UUID is usually some sort of MD5 checksum for the file and is sometimes known by dynamic linkers/loaders. If the UUID is known, it is best to supply it to platform file queries to ensure we are finding the correct file, not just a file at the correct path.
[out]	local_file	A locally cached version of the platform file. For platforms that describe the current host computer, this will just be the same file. For remote platforms, this file might come from and SDK directory, or might need to be sync'ed over to the current machine for efficient debugging access.

Returns

An error object.

Locate a queue ID given a thread's qaddr.

On a system using libdispatch ("Grand Central Dispatch") style queues, a thread may be associated with a GCD queue or not, and a queue may be associated with multiple threads. The process/thread must provide a way to find the "dispatch_qaddr" for each thread, and from that dispatch_qaddr this Platform method will locate the queue ID and provide that.

Parameters

[in]	process	A process is required for reading memory.
[in]	dispatch_qaddr	The dispatch_qaddr for this thread.

Returns

The queue_id for this thread, if this thread is associated with a dispatch queue. Else LLDB_INVALID_QUEUE_ID is returned.

GetTrapHandlerSymbolNames()

const std::vector< ConstString > & Platform::GetTrapHandlerSymbolNames ( )

virtual

Provide a list of trap handler function names for this platform.

The unwinder needs to treat trap handlers specially – the stack frame may not be aligned correctly for a trap handler (the kernel often won't perturb the stack pointer, or won't re-align it properly, in the process of calling the handler) and the frame above the handler needs to be treated by the unwinder's "frame 0" rules instead of its "middle of the stack frame" rules.

In a user process debugging scenario, the list of trap handlers is typically just "_sigtramp".

The Platform base class provides the m_trap_handlers ivar but it does not populate it. Subclasses should add the names of the asynchronous signal handler routines as needed. For most Unix platforms, add _sigtramp.

Returns

A list of symbol names. The list may be empty.

Install()

Status Platform::Install ( const FileSpec &  src, const FileSpec &  dst  )

virtual

Install a file or directory to the remote system.

Install is similar to Platform::PutFile(), but it differs in that if an application/framework/shared library is installed on a remote platform and the remote platform requires something to be done to register the application/framework/shared library, then this extra registration can be done.

Parameters

[in]	src	The source file/directory to install on the remote system.
[in]	dst	The destination file/directory where src will be installed. If dst has no filename specified, then its filename will be set from src. It dst has no directory specified, it will use the platform working directory. If dst has a directory specified, but the directory path is relative, the platform working directory will be prepended to the relative directory.

Returns

An error object that describes anything that went wrong.

		const lldb_private::FileSpec &	local_file,
		const lldb_private::FileSpec &	remote_file,
		lldb_private::Status &	error
	)

Load a shared library into this process.

Try and load a shared library into the current process. This call might fail in the dynamic loader plug-in says it isn't safe to try and load shared libraries at the moment.

Parameters

[in]	process	The process to load the image.
[in]	local_file	The file spec that points to the shared library that you want to load if the library is located on the host. The library will be copied over to the location specified by remote_file or into the current working directory with the same filename if the remote_file isn't specified.
[in]	remote_file	If local_file is specified then the location where the library should be copied over from the host. If local_file isn't specified, then the path for the shared library on the target what you want to load.
[out]	error	An error object that gets filled in with any errors that might occur when trying to load the shared library.

Returns

A token that represents the shared library that can be later used to unload the shared library. A value of LLDB_INVALID_IMAGE_TOKEN will be returned if the shared library can't be opened.

		lldb_private::Status &	error,
		lldb_private::FileSpec *	loaded_path
	)

Load a shared library specified by base name into this process, looking by hand along a set of paths.

Parameters

[in]	process	The process to load the image.
[in]	library_name	The name of the library to look for. If library_name is an absolute path, the basename will be extracted and searched for along the paths. This emulates the behavior of the loader when given an install name and a set (e.g. DYLD_LIBRARY_PATH provided) of alternate paths.
[in]	paths	The list of paths to use to search for the library. First match wins.
[out]	error	An error object that gets filled in with any errors that might occur when trying to load the shared library.
[out]	loaded_path	If non-null, the path to the dylib that was successfully loaded is stored in this path.

Returns

A token that represents the shared library which can be passed to UnloadImage. A value of LLDB_INVALID_IMAGE_TOKEN will be returned if the shared library can't be opened.

ResolveExecutable()

Status Platform::ResolveExecutable ( const ModuleSpec &  module_spec, lldb::ModuleSP &  module_sp, const FileSpecList *  module_search_paths_ptr  )

virtual

Find a platform plugin for a given process.

Scans the installed Platform plug-ins and tries to find an instance that can be used for process

Parameters

[in]	process	The process for which to try and locate a platform plug-in instance.
[in]	plugin_name	An optional name of a specific platform plug-in that should be used. If nullptr, pick the best plug-in. Set the target's executable based off of the existing architecture information in target given a path to an executable exe_file.

Each platform knows the architectures that it supports and can select the correct architecture slice within exe_file by inspecting the architecture in target. If the target had an architecture specified, then in can try and obey that request and optionally fail if the architecture doesn't match up. If no architecture is specified, the platform should select the default architecture from exe_file. Any application bundles or executable wrappers can also be inspected for the actual application binary within the bundle that should be used.

Returns

Returns true if this Platform plug-in was able to find a suitable executable, false otherwise.

ResolveSymbolFile()

Status Platform::ResolveSymbolFile ( Target &  target, const ModuleSpec &  sym_spec, FileSpec &  sym_file  )

virtual

Find a symbol file given a symbol file module specification.

Each platform might have tricks to find symbol files for an executable given information in a symbol file ModuleSpec. Some platforms might also support symbol files that are bundles and know how to extract the right symbol file given a bundle.

Parameters

[in]	target	The target in which we are trying to resolve the symbol file. The target has a list of modules that we might be able to use in order to help find the right symbol file. If the "m_file" or "m_platform_file" entries in the sym_spec are filled in, then we might be able to locate a module in the target, extract its UUID and locate a symbol file. If just the "m_uuid" is specified, then we might be able to find the module in the target that matches that UUID and pair the symbol file along with it. If just "m_symbol_file" is specified, we can use a variety of tricks to locate the symbols in an SDK, PDK, or other development kit location.
[in]	sym_spec	A module spec that describes some information about the symbol file we are trying to resolve. The ModuleSpec might contain the following: m_file - A full or partial path to an executable from the target (might be empty). m_platform_file - Another executable hint that contains the path to the file as known on the local/remote platform. m_symbol_file - A full or partial path to a symbol file or symbol bundle that should be used when trying to resolve the symbol file. m_arch - The architecture we are looking for when resolving the symbol file. m_uuid - The UUID of the executable and symbol file. This can often be used to match up an executable with a symbol file, or resolve an symbol file in a symbol file bundle.
[out]	sym_file	The resolved symbol file spec if the returned error indicates success.

Returns

Returns an error that describes success or failure.
