Detailed Description

The SgAsmGenericSection represents any contiguous region of a file that serves a particular purpose.

Not only are ELF and PE Sections represented by SgAsmGenericSection, but also such things as file headers, segment/section tables, etc.

Member Function Documentation

virtual SgNode* SgAsmGenericSection::copy ( SgCopyHelp &  help) const
virtual

This function clones the current IR node object recursively or not, depending on the argument.

This function performs a copy based on the specification of the input parameter. The input parameter is used to determin which data members are copied by reference and which are copied by value.

Parameters
help- If this argument is of type SgTreeCopy, then the IR node is cloned recursively. If its of type SgShallowCopy only the first level of the IR node is copied, everything else is left pointing to the the original IR node's object's data members.
Returns
a pointer to the new clone.

It appears the the copy functions don't set the parents of anything that they do a deep copy of! This can cause AST tests to fail. In particular some functions that require the parent pointers to be valid will return NULL pointers (e.g. SgInitializedName::get_declaration()). It might be that we should allow this to be done as part of the SgCopyHelp::clone function or perhaps another member function of SgCopyHelp would be useful for this support. It is not serious if the AST post processing is done since that will set any NULL pointers that are found within its traversal.

Exceptions
noneNo exceptions are thrown by this function.

void SgAsmGenericSection::grab_content ( )

Saves a reference to the original file data for a section based on the sections current offset and size.

Once we do this, changing the offset or size of the file will not affect the original data. The original data can be extended, however, by calling SgAsmGenericSection::extend(), which is typically done during parsing.

Move a section w/o regard to other sections or mapping.

Adjust the current offset of a section.

This is virtual because some sections may need to do something special. This function should not adjust the offset of other sections, or the mapping of any section.

void SgAsmGenericSection::extend ( rose_addr_t  size)

make section larger by extending the end

Extend a section by some number of bytes during the construction and/or parsing phase.

This is function is considered to be part of the parsing and construction of a section–it changes the part of the file that's considered the "original size" of the section. To adjust the size of a section after the executable file is parsed, see SgAsmGenericFile::resize(). Sections are allowed to extend beyond the end of the file and the original data (p_data) is extended only up to the end of the file.

Write data to a file section.

Parameters
fOutput steam to which to write
offsetByte offset relative to start of this section
bufsizeSize of buf in bytes
bufBuffer of bytes to be written
Returns
Returns the section-relative byte offset for the first byte beyond what would have been written if all bytes of the buffer were written.

The buffer is allowed to extend past the end of the section as long as the part that extends beyond is all zeros. The zeros will not be written to the output file. Furthermore, any trailing zeros that extend beyond the end of the file will not be written (end-of-file is determined by SgAsmGenericFile::get_orig_size())

Reads data from a file.

Reads up to size bytes of data beginning at byte start_va (absolute virtual address) in the mapped address space and placing the results in dst_buf and returning the number of bytes read. The return value could be smaller than size if the reading encounters virtual addresses that are not mapped.

unsigned char * SgAsmGenericSection::writable_content ( size_t  nbytes)

Sections typically point into the memory mapped, read-only file stored in the SgAsmGenericFile parent initialized by calling grab_content() (or indirectly by calling parse()).

This is also the same data which is, by default, written back out to the new file during unparse(). Programs modify section content by either overriding the unparse() method or by modifying the p_data values. But in order to modify p_data we have to make sure that it's pointing to a read/write memory pool. This function replaces the read-only memory pool with a new one containing nbytes bytes of zeros.

bool SgAsmGenericSection::align ( )

Increase file offset and mapping address to satisfy alignment constraints.

This is typically done when initializing a new section. The constructor places the new section at the end of the file before it knows what the alignment constraints will be. The user should then set the alignment constraints (see set_file_alignment() and set_mapped_alignment()) and call this method. This method must be called before any additional sections are appended to the file.

The file offset and memory mapping address are adjusted independently.

On the other hand, if additional sections are in the way, they must first be moved out of the way with the SgAsmGenericFile::shift_extend() method.

Returns true if the file offset and/or mapping address changed as a result of this call.

FOR INTERNAL USE within ROSE traverals mechanism only.

This function builds and returns a copy of ordered container holding pointers to children of this node in a traversal. It is associated with the definition of a tree that is travered by the AST traversal mechanism; a tree that is embeded in the AST (which is a more general graph). This function is used within the implementation of the AST traversal and has a semantics may change in subtle ways that makes it difficult to use in user code. It can return unexpected data members and thus the order and the number of elements is unpredicable and subject to change.

Warning
This function can return unexpected data members and thus the order and the number of elements is unpredicable and subject to change.
Returns
Returns ordered STL Container of pointers to children nodes in AST.

virtual std::vector<std::string> SgAsmGenericSection::get_traversalSuccessorNamesContainer ( )
virtual

FOR INTERNAL USE within ROSE traverals mechanism only.

This function builds and returns a copy of ordered container holding strings used to name data members that are traversed in the IR node. It is associated with the definition of a tree that is travered by the AST traversal mechanism; a tree that is embeded in the AST (which is a more general graph). This function is used within the implementation of the AST traversal and has a semantics may change in subtle ways that makes it difficult to use in user code. It can return unexpected data members and thus the order and the number of elements is unpredicable and subject to change.

Warning
This function can return unexpected data members and thus the order and the number of elements is unpredicable and subject to change.

Each string is a name of a member variable holding a pointer to a child in the AST. The names are the same as used in the generated enums for accessing attributes in a traversal. The order is the same in which they are traversed and the same in which the access enums are defined. Therefore this method can be used to get the corresponding name (string) of an access enum which allows to produce more meaningful messages for attribute computations.

Returns
Returns ordered STL container of names (strings) of access names to children nodes in AST.

virtual bool SgAsmGenericSection::isInMemoryPool ( )
virtual

FOR INTERNAL USE This is used in internal tests to verify that all IR nodes are allocated from the heap.

The AST File I/O depends upon the allocation of IR nodes being from the heap, stack based or global IR nodes should not appear in the AST if it will be written out to a file and read back in. To enforce this concept, this function implements a test to verify that the IR node can be found on the heap and is part of a larger test of the whole AST. This test must pass before the AST can be written out to a file. This is part of a compromise in the design of the AST File I/O to support binary streaming of data to files; for performance. It is also rather difficult, but possible, to build a useful AST with IR nodes allocated on the stack or frm global scope, this test filters out such cased from being used with the AST File I/O mechanism.

This functions is part of general support for many possible tools to operate on the AST. The forms a list of ALL IR node pointers used by each IR node, and is a supperset of the get_traversalSuccessorContainer(). It is (I think) less than the set of pointers used by the AST file I/O. This is part of work implemented by Andreas, and support tools such as the AST graph generation.

virtual long SgAsmGenericSection::getChildIndex ( SgNode *  childNode) const
virtual

FOR INTERNAL USE Returns a unique index value for the childNode in the list of children at this IR node.

This function returns a unique value for the input childNode in set of children at this IR node. Note that a negative value indicates that the input node is not a child. This is the basis for the implementation of the isChild(SgNode*) member function. Data members that are NULL in the IR node are counted internally (so that this function returns value that could be statically defined, and so are not dynamically determined).

Warning
The mapping on children to integer values could change from release to release of ROSE.

Member Data Documentation

unsigned char* SgAsmGenericSection::local_data_pool
private

This is an optional local, writable pool for the p_data member.

Normally a section will point into the pool for its SgAsmGenericFile which is memory-mapped (read-only) from the actual file being parsed. The default unparsing action is to write the original data back to the file. By allowing a section to allocate its own pool for p_data we create a very easy way to get data into the unparsed file (the alternative is to derive a new class and override the unparse() method).

This is the relative virtual address where the section prefers to be mapped.

The RVA where the section will ultimately be mapped by the loader might be different due to file and/or memory alignment constraints and conflicts with other sections.

bool SgAsmGenericSection::p_contains_code
protected

If a section is known to contain code then this data member is set.

Part of the process of parsing a binary file is to look at the symbol tables and if any function symbol points into a section then the entire section is marked as containing code. This is necessary because ELF Object Files (*.o files) contain one ELF Section per function, none of which have a memory mapping specification. By marking those sections as containing code, the LoaderELFObj class, knows that the section should be mapped to virtual memory for disassembly.

Definition at line 280296 of file Cxx_Grammar.h.

rose_addr_t SgAsmGenericSection::p_mapped_actual_va
protected

This is the virtual address where ROSE simulates a loader mapping the section.

The actual mapping is sometimes different than the preferred mapping indicated in the section table due to file and/or memory alignment constraints or conflicts with other sections. The only place values are assigned to this data member is in the BinaryLoader class and subclasses thereof.

The address corresponds to the latest call into the Loader classes. Depending on the loader employed, it's possible for a section to be mapped, the p_mapped_actual_va value to be set, and then some other section to be mapped over the top of all or part of the first section. In that case, the p_mapped_actual_va of the first section is not reset to zero. The return value is not conditional upon is_mapped() since that predicate applies only to preferred mapping attributes.
