Constructor Detail

DwarfLocSectionImpl

public DwarfLocSectionImpl(DwarfDebugInfo dwarfSections)

Method Detail

getSectionName

public String getSectionName()

Description copied from class: DwarfSectionImpl

Identify this debug section by name.

Specified by:

getSectionName in class DwarfSectionImpl

Returns:

the name of the debug section.

getDependencies

public Set<BuildDependency> getDependencies(Map<ObjectFile.Element,LayoutDecisionMap> decisions)

Description copied from interface: ElementImpl

Implementing this method allows to declare dependencies to other Sections (i.e. information about other sections needed to construct this section). The information will be used to construct the buildOrder in ObjectFile.writeInternal(). A good example can be found at: ELFObjectFile.ProgramHeaderTable.getDependencies

Specified by:

getDependencies in interface ElementImpl

Overrides:

getDependencies in class DwarfSectionImpl

createContent

public void createContent()

Description copied from class: DwarfSectionImpl

Creates the target byte[] array used to define the section contents. The main task of this method is to precompute the size of the debug section. given the complexity of the data layouts that invariably requires performing a dummy write of the contents, inserting bytes into a small, scratch buffer only when absolutely necessary. subclasses may also cache some information for use when writing the contents.

Specified by:

createContent in class DwarfSectionImpl

writeContent

public void writeContent(org.graalvm.compiler.debug.DebugContext context)

Description copied from class: DwarfSectionImpl

Populates the byte[] array used to contain the section contents. In most cases this task reruns the operations performed under createContent but this time actually writing data to the target byte[].

Specified by:

writeContent in class DwarfSectionImpl

targetSectionName

public String targetSectionName()

Description copied from class: DwarfSectionImpl

Identify the section after which this debug section needs to be ordered when sizing and creating content.

Specified by:

targetSectionName in class DwarfSectionImpl

Returns:

the name of the preceding section.

targetSectionKinds

public LayoutDecision.Kind[] targetSectionKinds()

Description copied from class: DwarfSectionImpl

Identify the layout properties of the target section which need to have been decided before the contents of this section can be created.

Specified by:

targetSectionKinds in class DwarfSectionImpl

Returns:

an array of the relevant decision kinds.
