- Update to version 1.8.0

* The --relocatable (or -r) option has been reimplemented to improve its
    performance and compatibility with the GNU linkers. That option tells the linker
    to combine input object files into another object file instead of into an
    executable or a shared library file. mold has been supporting the feature since
    version 0.9, but until now the output file created with -r looked fairly
    different from what GNU linkers would produce. GHC (Glasgow Haskell Compiler) in
    particular uses re-linkable object files as dynamic libraries instead of real
    .so files, and it didn't work with mold. Now, mold can produce object files that
    GHC can load. Note that this work was funded by Mercury, so thanks to the
    company to help us improve the product. (Yes, you can ask us to prioritize your
    feature request by funding the project.) (c9a7ae7)
  * --relocatable-merge-sections option has been added. By default, mold keeps
    original input section names for the --relocatable output and therefore does not
    merge input sections into a single output sections unless they are of the same
    name. If --relocatable-merge-sections is given, mold merges input by the usual
    default merging rule. For example, .text.foo and .text.bar are merged to .text
    if and only if --relocatable-merge-sections is given for the --relocatable
    output. (c2a0ae1)
  * -z [no]dynamic-undefined-weak options have been added. This option controls
    whether an undefined weak symbol is promoted to a dynamic symbol or not.
    (ed235f3)
  * --[no-]undefined-version options have been supported. Now, mold warns on a
    symbol name in a version script if it does not match with any defined symbol.
    This change was made so that it is easy to find a typo in a version script.
    (e2d7353)
  * mold now warns on symbol type mismatch. If two object files have the same symbol
    with different symbol types, it usually means your program has a bug. Chances
    are, you are using the same identifier as a function name in one translation
    unit and as a global variable name in another. So it makes sense to warn on the

with different symbol types, it usually means your program has a bug. Chances
are, you are using the same identifier as a function name in one translation
unit and as a global variable name in another. So it makes sense to warn on the
mismatch. (b70211e)
* mold now merges .gnu.note.property sections for various x86 properties.
(d30d743)
* The experimental macOS/iOS support has been removed from mold. If you want to
use it, please use our sold linker instead.
* --wrap now works with LTO. (07d8911)
* A global variable initialized with an IFUNC function pointer is now initialized
correctly with the function's address. Previously, it was mistakenly initialized
to the function resolver's address. (b2858d2)
* The filename specified by --version-script or --dynamic-list is now searched
from library search paths if it does not exist in the current working directory.
This behavior is compatible with GNU linkers. (3c1a055, 8c87f16)
* mold now tries to avoid creating copy relocations as much as possible. This
change fixed a compatibility issue with GHC. (5866c9e)
* Thread-local variables are now correctly aligned even if there's a TLV with a
large alignment. (bd46edf)
* mold can now handle GCC LTO files created with -ffat-lto-objects. (804b843)
* mold now accepts -z nopack-relative-relocs as an alias for
--pack-dyn-relocs=none for the sake of compatibility with GNU linkers. (b510588)
* mold now recognizes -z start-stop-visibility=hidden but ignores it because it's
the default for mold. GNU linkers support this option to control the visibility
of linker-synthesized __start_<sectname> and __stop_<sectname> symbols, with
global as the default visibility. mold creates these symbols with the hidden
visibility by default, which is desirable for almost all cases. (22c9ec8)
* [ARM32, i386] mold now emits REL-type relocations instead of RELA-type for the
--relocatable output file. (8b373d3)
