Detailed Description

A class that describes an executable image and its associated object and symbol files.

The module is designed to be able to select a single slice of an executable image as it would appear on disk and during program execution.

Modules control when and if information is parsed according to which accessors are called. For example the object file (ObjectFile) representation will only be parsed if the object file is requested using the Module::GetObjectFile() is called. The debug symbols will only be parsed if the symbol file (SymbolFile) is requested using the Module::GetSymbolFile() method.

The module will parse more detailed information as more queries are made.

Dump()

void Module::Dump

(

Stream *

s

)

Dump a description of this object to a Stream.

Dump a description of the contents of this object to the supplied stream s. The dumped content will be only what has been loaded or parsed up to this point at which this function is called, so this is a good way to see what has been parsed in a module.

Parameters

[in]

s

The stream to which to dump the object description.

FindSourceFile()

bool Module::FindSourceFile	(	const FileSpec &	orig_spec,
		FileSpec &	new_spec
	)		const

Finds a source file given a file spec using the module source path remappings (if any).

Tries to resolve orig_spec by checking the module source path remappings. It makes sure the file exists, so this call can be expensive if the remappings are on a network file system, so use this function sparingly (not in a tight debug info parsing loop).

Parameters

[in]	orig_spec	The original source file path to try and remap.
[out]	new_spec	The newly remapped filespec that is guaranteed to exist.

Returns

GetSpecificationDescription()

std::string Module::GetSpecificationDescription

(

)

const

Get the module path and object name.

Modules can refer to object files. In this case the specification is simple and would return the path to the file:

"/usr/lib/foo.dylib"

Modules can be .o files inside of a BSD archive (.a file). In this case, the object specification will look like:

"/usr/lib/foo.a(bar.o)"

There are many places where logging wants to log this fully qualified specification, so we centralize this functionality here.

• just a regular object file (mach-o, elf, coff, etc) should create a hash
• a universal mach-o file that contains to multiple architectures, each architecture slice should have a unique hash even though they come from the same file
• a .o file inside of a BSD archive. Each .o file will have an object name and object offset that should produce a unique hash. The object offset is needed as BSD archive files can contain multiple .o files that have the same name.

[in]

path

The original source file path to try and remap.

Returns

The newly remapped filespec that is may or may not exist if path was successfully located.

		lldb::SymbolContextItem	resolve_scope,
		SymbolContext &	sc,
		bool	resolve_tail_call_address = false
	)

Resolve the symbol context for the given address.

Tries to resolve the matching symbol context based on a lookup from the current symbol vendor. If the lazy lookup fails, an attempt is made to parse the eh_frame section to handle stripped symbols. If this fails, an attempt is made to resolve the symbol to the previous address to handle the case of a function with a tail call.

Use properties of the modified SymbolContext to inspect any resolved target, module, compilation unit, symbol, function, function block or line entry. Use the return value to determine which of these properties have been modified.

Parameters

[in]	so_addr	A load address to resolve.
[in]	resolve_scope	The scope that should be resolved (see SymbolContext::Scope). A combination of flags from the enumeration SymbolContextItem requesting a resolution depth. Note that the flags that are actually resolved may be a superset of the requested flags. For instance, eSymbolContextSymbol requires resolution of eSymbolContextModule, and eSymbolContextFunction requires eSymbolContextSymbol.
[out]	sc	The SymbolContext that is modified based on symbol resolution.
[in]	resolve_tail_call_address	Determines if so_addr should resolve to a symbol in the case of a function whose last instruction is a call. In this case, the PC can be one past the address range of the function.

Returns

The scope that has been resolved (see SymbolContext::Scope).

		bool	check_inlines,
		lldb::SymbolContextItem	resolve_scope,
		SymbolContextList &	sc_list
	)

Resolve items in the symbol context for a given file and line.

Tries to resolve file_path and line to a list of matching symbol contexts.

The line table entries contains addresses that can be used to further resolve the values in each match: the function, block, symbol. Care should be taken to minimize the amount of information that is requested to only what is needed – typically the module, compile unit, line table and line table entry are sufficient.

Parameters

[in]	file_path	A path to a source file to match. If file_path does not specify a directory, then this query will match all files whose base filename matches. If file_path does specify a directory, the fullpath to the file must match.
[in]	line	The source line to match, or zero if just the compile unit should be resolved.
[in]	check_inlines	Check for inline file and line number matches. This option should be used sparingly as it will cause all line tables for every compile unit to be parsed and searched for matching inline file entries.
[in]	resolve_scope	The scope that should be resolved (see SymbolContext::Scope).
[out]	sc_list	A symbol context list that gets matching symbols contexts appended to.

Returns

The number of matches that were added to sc_list.

Resolve items in the symbol context for a given file and line.

Tries to resolve file_spec and line to a list of matching symbol contexts.

The line table entries contains addresses that can be used to further resolve the values in each match: the function, block, symbol. Care should be taken to minimize the amount of information that is requested to only what is needed – typically the module, compile unit, line table and line table entry are sufficient.

Parameters

[in]	file_spec	A file spec to a source file to match. If file_path does not specify a directory, then this query will match all files whose base filename matches. If file_path does specify a directory, the fullpath to the file must match.
[in]	line	The source line to match, or zero if just the compile unit should be resolved.

SetLoadAddress()

bool Module::SetLoadAddress	(	Target &	target,
		lldb::addr_t	value,
		bool	value_is_offset,
		bool &	changed
	)

Set the load address for all sections in a module to be the file address plus slide.

Many times a module will be loaded in a target with a constant offset applied to all top level sections. This function can set the load address for all top level sections to be the section file address + offset.

Parameters

[in]	target	The target in which to apply the section load addresses.
[in]	value	if value_is_offset is true, then value is the offset to apply to all file addresses for all top level sections in the object file as each section load address is being set. If value_is_offset is false, then "value" is the new absolute base address for the image.
[in]	value_is_offset	If true, then value is an offset to apply to each file address of each top level section. If false, then value is the image base address that will be used to rigidly slide all loadable sections.
[out]	changed	If any section load addresses were changed in target, then changed will be set to true. Else changed will be set to false. This allows this function to be called multiple times on the same module for the same target. If the module hasn't moved, then changed will be false and no module updated notification will need to be sent out.

Returns

/b True if any sections were successfully loaded in target, /b false otherwise.
