Non-comprehensive list of changes in this release
|
|
=================================================
|
|
|
|
ELF Improvements
|
|
----------------
|
|
|
|
* ``-z pack-relative-relocs`` is now available to support ``DT_RELR`` for glibc 2.36+.
|
|
(`D120701 <https://reviews.llvm.org/D120701>`_)
|
|
* ``--no-fortran-common`` (pre 12.0.0 behavior) is now the default.
|
|
|
|
Breaking changes
|
|
----------------
|
|
|
|
* The GNU ld incompatible ``--no-define-common`` has been removed.
|
|
* The obscure ``-dc``/``-dp`` options have been removed.
|
|
* ``-d`` is now ignored.
|
|
* If a prevailing COMDAT group defines STB_WEAK symbol, having a STB_GLOBAL symbol in a non-prevailing group is now rejected with a diagnostic.
|
|
(`D120626 <https://reviews.llvm.org/D120626>`_)
|
|
|
|
COFF Improvements
|
|
-----------------
|
|
|
|
* Added autodetection of MSVC toolchain, a la clang-cl. Also added
|
|
``/winsysroot:`` support for explicit specification of MSVC toolchain
|
|
location, similar to clang-cl's ``/winsysroot``. For now,
|
|
``/winsysroot:`` requires also passing in an explicit ``/machine:`` flag.
