Release Information

Changes in this release

This is the first public release of the Elftoolchain sources.

Differences with prior FreeBSD versions of some components

Some of the libraries and utilities in this release were originally developed at the FreeBSD_ project. These components differ from their prior versions in FreeBSD source tree in the following ways:

  • ar
    ar supports BSD-style archives.
  • brandelf
    brandelf supports additional ELF brands.
  • libdwarf
    The libdwarf library implements the complete DWARF(3) producer and consumer API set. Each public API has been documented in the form of a manual page.
  • libelf
    • libelf supports operations on special devices in addition to regular files.
    • libelf supports opening of ELF objects in read/write mode.
    • The archive handling APIs in libelf can process BSD-style archives.
    • ELF sections containing GNU-style hash tables are supported.
    • ELF sections containing GNU-style symbol versioning information are supported.
    • Numerous bugs in the code have been fixed.

Additionally, the manual pages associated with these components have been improved.

Outstanding Issues

There were no outstanding issues at the time of the release.

Known Limitations

This release has the following limitations:

  • Test coverage
    Our test suites are being developed; test coverage for this release is partial.
  • Performance and Memory Use
    Our tools have not been characterized for their memory usage or for their performance characteristics.

We hope to address these limitations in future releases.
