PlatformSP PlatformList::GetOrCreate	(	llvm::ArrayRef< ArchSpec >	archs,
		const ArchSpec &	process_host_arch,
		std::vector< lldb::PlatformSP > &	candidates
	)

Get the platform for the given list of architectures.

The algorithm works a follows:

1. Returns the selected platform if it matches any of the architectures.
2. Returns the host platform if it matches any of the architectures.
3. Returns the platform that matches all the architectures.

If none of the above apply, this function returns a default platform. The candidates output argument differentiates between either no platforms supporting the given architecture or multiple platforms supporting the given architecture.

GetSelectedPlatform()

lldb::PlatformSP lldb_private::PlatformList::GetSelectedPlatform ( )

inline

Select the active platform.

In order to debug remotely, other platform's can be remotely connected to and set as the selected platform for any subsequent debugging. This allows connection to remote targets and allows the ability to discover process info, launch and attach to remote processes.

LoadPlatformBinaryAndSetup()

bool PlatformList::LoadPlatformBinaryAndSetup	(	Process *	process,
		lldb::addr_t	addr,
		bool	notify
	)

Detect a binary in memory that will determine which Platform and DynamicLoader should be used in this target/process, and update the Platform/DynamicLoader.

The binary will be loaded into the Target, or will be registered with the DynamicLoader so that it will be loaded at a later stage. Returns true to indicate that this is a platform binary and has been loaded/registered, no further action should be taken by the caller.

Parameters

[in]	process	Process read memory from, a Process must be provided.
[in]	addr	Address of a binary in memory.
[in]	notify	Whether ModulesDidLoad should be called, if a binary is loaded. Caller may prefer to call ModulesDidLoad for multiple binaries that were loaded at the same time.

Returns

Returns true if the binary was loaded in the target (or will be via a DynamicLoader). Returns false if the binary was not loaded/registered, and the caller must load it into the target.
