Martin Liška 714a1a35c3 - 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)

- Update to version 1.7.1
* mold 1.7.0 may generate the same build-id for two different output files. We
fixed the issue in 1.7.1 so that build-id is guaranteed to be unique for each
different output file. (d8dd124)
-------------------------------------------------------------------
Mon Nov 14 11:12:19 UTC 2022 - Martin Liška <mliska@suse.cz>
- Update to version 1.7.0
* [m68k] mold now supports the Motorola 68000 series microprocessors. Yes, it's
the processor in the original Mac or Sun workstations in the 80s. This work is
sponsored by m68k hobbyist communities.
* We fixed a few issues for Facebook/Meta's BOLT optimizer (#789). Starting from
the next LLVM release (we need llvm/llvm-project@20204db), BOLT should work on
mold-generated executables out of the box.
* We fixed a long-standing symbol resolution issue involving GNU UNIQUE symbols
which caused a link failure for a few programs. (730e970)
* Previously, if a version script contains a "C++" directive, and a symbol matches
a non-C++ version pattern and a C++ version pattern, a wrong version could be
assigned to the symbol. This has been fixed so that the mold's behavior matches
with GNU ld. (9875150)
-------------------------------------------------------------------
Wed Oct 19 08:20:22 UTC 2022 - Martin Liška <mliska@suse.cz>
- Update to version 1.6.0
* [ppc64] mold now supports the original 64-bit big-endian PowerPC ABI (which is
also known as PPC64 ELFv1 or just ppc64), so that you can build applications for
older PPC64 systems with mold. Note that this should not be confused with the
modern PPC64 ELFv2 ABI (which is also known as ppc64le), which is already
supported by mold.
* [s390x] Linux/s390x is now supported. Linux/s390x is the Linux environment
running on IBM z/Architecture mainframes. I've personally never seen a
mainframe, but we wanted to support it because many Linux distros actively
support that target, which in turn means there are many enterprise users who are
using IBM mainframes. Speaking of the porting effort, we do not only port our
linker to s390x but also found a couple of issues with the existing GCC
toolchain for s390x. So, we are improving the whole IBM mainframe ecosystem!
* mold now creates smaller output files. It is most noticeable on targets with
large page sizes such as PPC64 (on which the common page size is 64 KiB), but
even on x86-64, it should save a few kilobytes per an output file.
* [arm64] mold can now link executables with -static-pie. Previously, executables
linked with that flag crashed immediately.
- Exclude ppc architecture as it is not supported right now.
-------------------------------------------------------------------
Thu Sep 29 07:06:19 UTC 2022 - Martin Liška <mliska@suse.cz>
- Update to version 1.5.1
* We changed the memory layout to save both memory and disk space in 1.5.0. Even
though the new layout works fine on most systems, the change made the linker to
create unusable executables for systems with large pages. Specifically, if you
specify a large number for the -z max-page-size option, the loader refused to
execute it with the error while loading shared libraries: cannot apply
additional memory protection after relocation: Cannot allocate memory error. We
reverted our recent commits so that mold creates output files with the same
memory layout as it did before 1.5.0. (e62de0b)
-------------------------------------------------------------------
Tue Sep 27 07:10:17 UTC 2022 - Martin Liška <mliska@suse.cz>
- Update to version 1.5.0
* PPC64LE and SPARC64 are now supported as new targets. They haven't yet been as
well tested as other targets, but they are already able to link mold itself on
these platforms. (Note that PPC64LE is very unlikely to work on the most recent
POWER10 machines as we didn't have a chance to test it due to a limited
availability (POWER10 was released in 2021). If you can support us on this
matter, please contact us. We also accept donations, so please consider
supporting our project!)
* RV32BE and RV64BE (32-bit and 64-bit big-endian RISC-V) are now supported as
experimental targets. RISC-V is usually little-endian, but there exists a
big-endian RISC-V as an extension. You can make gcc to emit code for big-endian
RISC-V by passing -mbig-endian. mold can now link object files generated with
that option.
* --compress-debug-sections=zstd is now supported. This is an option to compress
debug info embedded to an output file with Zstandard compression algorithm.
Compared to the existing --compress-debug-sections=zlib, zstd is faster and
gives a higher compression ratio. You probably can't start using zstd
compression today though, because other tools such as gdb may not be able to
read zstd-compressed debug info yet. But adding this option early makes mold
future-proof. (ede7a5a)
* mold no longer aligns loadable segments to page boundaries to reduce output file
size. Previously, we allocated holes between loadable segments. The saving by
this change is most visible for small programs. For example, a "hello world"
program used to be ~18 KiB on x86-64. It's now 7.2 KiB. (2941d75)
* Bug fixes and compatibility improvements
* [RISCV] We optimized code so that the link speed for RISC-V is now comparable to
the other targets. As an example, linking mold itself (~150 MiB in size) for
RV64 used to take ~45 seconds on a simulated 16-core machine. It now takes only
~0.25 seconds. (3ab5489)
* mold used to create more than one .rodata section under a certain condition.
It's not technically wrong but confused Valgrind. This issue has been resolved.
(25c7aee)
* [ARM32] Previously, mold failed to promote remaining undefined symbols to
dynamic symbols if symbols are undefined weak. That caused a link failure for
libxml (#660). This issue has been resolved. (72e26d9)
* mold didn't copy symbol types when creating symbol aliases for the --defsym
option. (8c7f31c)
* --compress-debug-sections=zlib-gnu has been removed. LLVM lld removed that
option too as there seems to be no usage of the flag.
- Enable ppc64le and use system zstd library as package dependency.
-------------------------------------------------------------------
Sun Sep 4 06:29:52 UTC 2022 - Martin Liška <mliska@suse.cz>
- Update to version 1.4.2
* [RV32] We've fixed several issues for 32-bit RISC-V.
mold can now build complex programs including itself for the target.
* [ARM32] mold gained range extension thunks so that it can now link programs whose
.text is larger than 16 MiB. Previously, mold couldn't link such large programs.
We've also fixed general stability issues for ARM32.
-------------------------------------------------------------------
Thu Aug 18 09:28:25 UTC 2022 - Martin Liška <mliska@suse.cz>
- Update to version 1.4.1
* mold/macOS is now available as an alpha feature. We do not recommend using it for anything
serious though. Starting from this version, we accept not only mold/Unix issues but also
mold/macOS ones on our GitHub Issues. Feel free to file a bug if you encounter any problem.
* We started supporting CMake in addition to Make to build mold. Our long-term plan is to migrate
from Make to CMake because we want to support Windows eventually and CMake provides
a better Windows support than Make does. (e6a0e67)
* There was a bug that mold accidentally exported a hidden symbol from an executable
if a shared library linked to that executable happened to define the same symbol.
This caused a build issue with Blender (#606). The bug has been fixed. (b163068)
--hash-style=both is now the default if no --hash-style option is given. Previously,
--hash-style=sysv was the default. This change shouldn't affect most users because
the compiler driver (cc, gcc, clang, etc.) always passes --hash-style to the linker.
We made this change because GNU ld defaults to --hash-style=both.
* Alias symbols defined by the --defsym option now have the same scope as the aliased symbols.
Previously, alias symbols defined by --defsym were always hidden and never
be exported as dynamic symbols. (5dd1227)
* mold now accepts foo = bar-style linker script directive to define symbol aliases.
Previously, such statement was treated as a syntax error.
This change was made to link mariadb-connector-c correctly (f0e1237)
* Symbols in mergeable string sections now have correct output section
indices instead of SHN_UNDEF. (a595c48)
* [ARM32] Previously, calling a function from ARM code to Thumb code
caused a program crash due to bug #442. This issue has been fixed. (053b90b)
- Run tests in parallel.
-------------------------------------------------------------------
Fri Aug 5 16:54:51 UTC 2022 - Martin Liška <mliska@suse.cz>
- Update to version 1.4.0
* Initial support for the 32-bit RISC-V (RV32) has landed. (d9db6bc)
* mold now demangles Rust symbols in error messages thanks to @eddyb's rust-demangle.c. (22e1bba)
* --export-dynamic-symbol and --export-dynamic-symbol-list are now supported for
the sake of compatibility with LLVM lld. With these options, you can specify
symbols that should be exported using glob pattern. (e115aae)
* [x86-64] PLT entries created by mold now always begins with ENDBR64 instruction
to improve compatibility with Intel IBT (Indirect Branch Tracking.) (e3e371d)
* mold now defines __dso_handle symbol. The lack of this linker-synthesized symbol
caused a link error with GCC in some environments (#507). (764d757)
- Remove fix-tests.patch.

Fri Jul 1 09:13:58 UTC 2022 - Martin Liška <mliska@suse.cz>
- Update to version 1.3.1
* mold now supports .preinit_array sections. Without this,
AddressSanitizer didn't work in some environments. (3b75398)
* [ARM32] R_ARM_MOVT_PREL and R_ARM_PREL31 relocations are now handled
correctly so that mold no longer emit spurious "recompile with -fPIC" errors. (5294300)
-------------------------------------------------------------------
Sat Jun 18 07:10:09 UTC 2022 - Martin Liška <mliska@suse.cz>
- Update to version 1.3.0
* The --icf=safe option has been supported.
* LTO now works reliably under a heavy load.
mold used to abort occasionally under such condition on Linux
due to a spurious failure of pthread_create(2). (d8a8877)
* mold now prints out undefined symbol errors in a format similar to LLVM lld. (13816a1)
* mold now prints out a better error message for the disk full situation. (5969260)
* mold can now build GCC 12 with LTO. (708ad63)
* Fixed an LTO issue on 32-bits hosts such as i686. (920266b)
* mold is now AddressSanitizer and UndefinedSanitizer clean. (fafb75b, 3499ee6)
* mold used to create broken debug info on 32-bits hosts (#490).
The bug has been fixed. (0abd0a4)
* mold used to accept not only a single dash but also double
dashes for single-letter options. For example, --S was accidentally accepted as an alias for-S.
This is unconventional, and such options are no longer accepted. (232dafa)
* --color-diagnostics is now an alias for --color-diagnostics=auto
instead of --color-diagnostics=always for compatibility with LLVM lld.
* pkg-config is no longer needed to build mold.
* The --package-metadata option is supported. (#505, e9f6715)

* Various bugs in --gdb-index have been fixed.
* mold now recognizes --thinlto-cache-dir and --thinlto-cache-policy
for the sake of compatibility with LLVM lld. (7ebd071)
* mold can now handle TLS common symbols. It looks like GCC
sometimes creates such symbol for a thread-local variable. (cf850f8)
* In some edge cases, mold created a non-versioned symbol and
a versioned one for the same symbol, even though if one symbol is versioned,
all symbols of the same name must be versioned.
This bug has been fixed. (8298c0a)
* mold used to write a PLT address of a symbol instead
of its address to .symtab. This bug has been fixed. (e088db7)
* mold can now handle an input file
with more than 219 symbols. (f1f2d40)
* /usr/local/libexec/mold/ld is now installed

* make install now creates /usr/local/libexec/mold/ld as
a symlink to the mold executable. We do this for GCC.
By passing -B/usr/local/libexec/mold, you can tell GCC to use ld
inside that directory instead of /usr/bin/ld. (e8dcecf)
* xxHash library is now included in the mold's source tree as a subtree for ease of building.
If you want to link against a libxxhash in a system library directory, pass SYSTEM_XXHASH=1 to make. (665bffa)
* The extern "C++" directive is now supported in the dynamic list. (7aa5c39)
* --color-diagnostics is supported. mold used to ignore that flag. (6e290aa)
* Not only * but also ? are now treated as special characters in the version script wildcard pattern. (31b0248)
