◆ adjustVma()

void ghidra::LoadImageBfd::adjustVma ( long adjust )

virtual

Adjust load addresses with a global offset.

Most load image formats automatically encode information about the true loading address(es) for the data in the image. But if this is missing or incorrect, this routine can be used to make a global adjustment to the load address. Only one adjustment is made across all addresses in the image. The offset passed to this method is added to the stored or default value for any address queried in the image. This is most often used in a raw binary file format. In this case, the entire executable file is intended to be read straight into RAM, as one contiguous chunk, in order to be executed. In the absence of any other info, the first byte of the image file is loaded at offset 0. This method then would adjust the load address of the first byte.

Parameters

adjust is the offset amount to be added to default values

Implements ghidra::LoadImage.

◆ closeSectionInfo()

void ghidra::LoadImageBfd::closeSectionInfo ( void ) const

virtual

Stop reading section info.

Once all the section information is read from the load image using the getNextSection() method, this method should be called to free up any resources used in parsing the section info.

Reimplemented from ghidra::LoadImage.

◆ closeSymbols()

void ghidra::LoadImageBfd::closeSymbols ( void ) const

virtual

Stop reading symbols.

Once all the symbol information has been read out from the load image via the openSymbols() and getNextSymbol() calls, the application should call this method to free up resources used in parsing the symbol information.

Reimplemented from ghidra::LoadImage.

◆ getArchType()

string ghidra::LoadImageBfd::getArchType ( void ) const

virtual

Get a string indicating the architecture type.

The load image class is intended to be a generic front-end to the large variety of load formats in use. This method should return a string that identifies the particular architecture this particular image is intended to run on. It is currently the responsibility of any derived LoadImage class to establish a format for this string, but it should generally contain some indication of the operating system and the processor.

Returns: the identifier string

Implements ghidra::LoadImage.

◆ getNextSection()

bool ghidra::LoadImageBfd::getNextSection ( LoadImageSection & record ) const

virtual

Get info on the next section.

This method is used to read out a record that describes a single section of bytes mapped by the load image. This method can be called repeatedly until it returns false, to get info on additional sections.

Parameters

record is a reference to the info record to be filled in

Returns: true if there are more records to read

Reimplemented from ghidra::LoadImage.

References ghidra::LoadImageSection::address, ghidra::LoadImageSection::flags, and ghidra::LoadImageSection::size.

◆ getNextSymbol()

bool ghidra::LoadImageBfd::getNextSymbol ( LoadImageFunc & record ) const

virtual

Get the next symbol record.

This method is used to read out an individual symbol record, LoadImageFunc, from the load image. Right now, the only information that can be read out are function starts and the associated function name. This method can be called repeatedly to iterate through all the symbols, until it returns false. This indicates the end of the symbols.

Parameters

record is a reference to the symbol record to be filled in

Returns: true if there are more records to read

Reimplemented from ghidra::LoadImage.

References ghidra::LoadImageFunc::address, and ghidra::LoadImageFunc::name.

◆ getReadonly()

void ghidra::LoadImageBfd::getReadonly ( RangeList & list ) const

virtual

Return list of readonly address ranges.

This method should read out information about all address ranges within the load image that are known to be readonly. This method is intended to be called only once, so all information should be written to the passed RangeList object.

Parameters

list	is where readonly info will get put

Reimplemented from ghidra::LoadImage.

References ghidra::RangeList::insertRange().

◆ loadFill()

void ghidra::LoadImageBfd::loadFill	(	uint1 *	ptr,
		int4	size,
		const Address &	addr
	)

virtual

Get data from the LoadImage.

This is the core routine of a LoadImage. Given a particular address range, this routine retrieves the exact byte values that are stored at that address when the executable is loaded into RAM. The caller must supply a pre-allocated array of bytes where the returned bytes should be stored. If the requested address range does not exist in the image, or otherwise can't be retrieved, this method throws an DataUnavailError exception.

Parameters

ptr	points to where the resulting bytes will be stored
size	is the number of bytes to retrieve from the image
addr	is the starting address of the bytes to retrieve

Implements ghidra::LoadImage.

◆ openSectionInfo()

void ghidra::LoadImageBfd::openSectionInfo ( void ) const

virtual

Prepare to read section info.

This method initializes iteration over all the sections of bytes that are mapped by the load image. Once this is called, information on individual sections should be read out with the getNextSection() method.

Reimplemented from ghidra::LoadImage.

◆ openSymbols()

void ghidra::LoadImageBfd::openSymbols ( void ) const

virtual

Prepare to read symbols.

This routine should read in and parse any symbol information that the load image contains about executable. Once this method is called, individual symbol records are read out using the getNextSymbol() method.

Reimplemented from ghidra::LoadImage.
