23 Non-comprehensive list of changes in this release
24 =================================================
29 * ``-z nosectionheader`` has been implemented to omit the section header table.
30 The operation is similar to ``llvm-objcopy --strip-sections``.
31 (`#101286 <https://github.com/llvm/llvm-project/pull/101286>`_)
32 * Section ``CLASS`` linker script syntax binds input sections to named classes,
33 which are referenced later one or more times. This provides access to the
34 automatic spilling mechanism of `--enable-non-contiguous-regions` without
35 globally changing the semantics of section matching. It also independently
36 increases the expressive power of linker scripts.
37 (`#95323 <https://github.com/llvm/llvm-project/pull/95323>`_)
44 * ``/includeglob`` has been implemented to match the behavior of ``--undefined-glob`` available for ELF.
45 * ``/lldsavetemps`` allows saving select intermediate LTO compilation results (e.g. resolution, preopt, promote, internalize, import, opt, precodegen, prelink, combinedindex).
46 * ``/machine:arm64ec`` support completed, enabling the linking of ARM64EC images.
47 * COFF weak anti-dependency alias symbols are now supported.
51 * ``--undefined-glob`` is now supported by translating into the ``/includeglob`` flag.
