/**
|
|
The ElfImporter is not a real trace importer, but we locate it
|
|
into the import-trace utility, since here the infrastructure is
|
|
already in place to import things related to an ELF binary into
|
|
the database.
|
|
|
|
The ElfImporter calls objdump to dissassemble an ELF binary, and
|
|
imports the results into the database.
|
|
|
|
In addition, debugging information can be imported: If the --sources
|
|
option is set, the source files will be imported into the database.
|
|
Only the files that were actually used in the ELF binary will be imported.
|
|
Additionally, the line number table of the ELF binary will be imported
|
|
into the database.
