* Thu Nov 30 2023 Martin Liška <martin.liska@hey.com>
- Update to version 2.4.0
* mold gained the --spare-program-headers=<number> option, which adds a specified
number of spare entries at the end of the program header. The option aims to
make post-processing tools to add program header entries very easily. Note that
sorting program header entries after adding new ones may be necessary to meet
the constraints of the ELF file format. For details, see the elf(5) man page.
(eb6c213)
* mold's -z rewrite-endbr option rewrites superflous endbr64 instructions with nop
as a countermeasure against control-flow highjacking attacks. Previously, this
worked exclusively with object files compiled with -ffunction-sections,
requiring each function to be compiled into a separate section. Starting from
this release, -z rewrite-endbr works on object files compiled without it. In
other words, mold is now capable of rewriting endbr64 instructions even if the
instruction is not at the beginning of a section. (3cb8a52)
* Previously, mold couldn't handle object files containing multiple .eh_frame
sections. The .eh_frame is a section containing data for exception handling.
Usually, an object file contains only one .eh_frame which describes how to
handle exceptions for all text sections in the same file. However, on rare
conditions, it seems ld -r creates an object file containing multiple .eh_frame
sections. mold is now able to handle such object files. (f4c5a8a)
* mold -run <command> is an easy way to run the given command with a virtual
environment in which the ld command is replaced with mold. The feature is
implemented using LD_PRELOAD to hook fork(2)-family functions. Before this
release, some invocations of ld were not intercepted correctly because we missed
the posix_spawnp(2) function. Now, the function is intercepted just like other
fork(2)-family functions. (3fd1cec)
* mold used to produce a non-working executable on a rare occasion when all
thread-local variables lacked an initial value and the read-only data required
alignment equal to or greater than the page size. This bug has been resolved.
(de7d37e)
* Previously, mold might assign a different symbol version to a symbol compared to
GNU ld if it matches both a wildcard pattern and an exact pattern in a version
script. Our behavior is now compatible with that of GNU ld. (0fdbace)
* [x86-64, i686] Recent versions of LLVM emit a machine code sequence for TLSDESC
thread-local variables that differs from GCC's, and mold previously
mis-optimized this sequence, leading to crashes in the linked programs. In other
words, if you are using LLVM/Clang and compile object files with
- mtls-dialect=gnu2, mold might mis-optimize the output file. Now, the bug has
been fixed. (000ce0e)
* Tue Nov 14 2023 Martin Liška <martin.liska@hey.com>
- Update to version 2.3.3
* --dynamic-list has different semantics for executables and DSOs. Previously,
mold implemented only the semantics for executables, causing issues with
libraries such as musl that used this option. mold now handles the option for
DSOs correctly. (da3f5dd)
* Old object files often contain .ctors and .dtors sections, which hold function
pointers for initializing and finalizing processes, respectively. Their roles
have been superseded by .init_array and .fini_array on most targets. mold worked
functioned correctly as long as input object files consistently use the old or
the new sections. However, mixing object files that contain both types of
initializers/finalizers resulted in some functions not being executed. This
issue has been fixed. (3f88964)
* --defsym can cause the linker to crash if a given symbol is not defined. The
crash bug has been fixed. (ff3d54d)
* [POWER10] On rare occasions, pointers statically initialized to functions could
be left as null pointers. This bug has been fixed. (31c3b53)
- Remove upstreamed patch power10-fix.patch.
* Mon Nov 06 2023 Martin Liška <martin.liska@hey.com>
- Add power10 fix power10-fix.patch for #1142.
* Sun Nov 05 2023 Martin Liška <martin.liska@hey.com>
- Update to version 2.3.2
* Remove upstream patch fix-arm.patch.
* mold no longer emits dynamic relocations against the text segment for GNU ifunc
symbols. Previously, mold emitted such relocations for position-dependent
executables. (4cdfc7e)
* mold no longer reports the "REL-type relocation table is not supported for this
target" error and instead ignore incompatible relocation tables. LLVM generates
such non-conforming relocation tables for the .llvm.call-graph-profile section.
This change was made for compatibility. (3791900)
* mold now pads unused gaps in the text segment with interrupt or NOP
instructions, instead of leaving them filled with zeros. This alteration does
not change the program's semantics but prevents disassemblers from interpreting
the spaces between functions as valid instructions. (c86a59a)
* mold now creates the .mold-lock file for MOLD_JOBS not in the home directory but
in $XDG_RUNTIME_DIR, which is usually /var/user/<uid>. (39cdf61)
* [ARM32] There was an issue preventing mold from being built on an ARMv8 64-bit
ARM processor with an ARM32 userland, such as the 32-bit Raspberry Pi OS running
on a Raspberry Pi 4. This build issue has been resolved. (02ead29)
* [LoongArch] mold can now handle R_LARCH_PCALA_LO12 relocation for the jirl
instruction. (d3188e3)
* Wed Oct 25 2023 Martin Liška <martin.liska@hey.com>
- Add fix-arm.patch in order to fix failing arm-arm_range-extension-thunk2 test.
* Fri Oct 20 2023 Martin Liška <martin.liska@hey.com>
- Update to version 2.3.1
* [ARM32, ARM64, PowerPC, LoongArch] mold 2.3.0 would crash when handling large
output files. This was due to a bug in the code that creates range extension
thunks. This issue has now been resolved. (7be1b66)
* [LoongArch] mold is now capable of handling relocations generated for the
- mcmodel=extreme flag. (4bd80ec)
* Wed Oct 18 2023 Martin Liska <martin.liska@melowntech.com>
- Update to version 2.3.0
* [x86-64] mold 2.3.0 has introduced an experimental flag, -z rewrite-endbr, which
rewrites superfluous endbr64 instructions as nop.
* endbr64 is a relatively recent x86 instruction used to mark locations where an
indirect jump instruction can transfer control. With control-flow integrity
enabled (meaning endbr64 is effective), an indirect jump can only target an
endbr64 or it will trigger a runtime exception. This mechanism significantly
hinders certain control hijacking attacks, such as ROP or JOP, since attackers
cannot jump to just any location.
* When given the -fcf-protection flag, GCC conservatively places an endbr64 at the
beginning of every global function. This is because the function's address might
be taken as a pointer by other translation units. However, in most cases,
function addresses are not actually taken. This conservative approach results in
an overabundance of unnecessary endbr64 instructions, leading to not only code
bloating but also a potential decrease in security as there are more locations
for an attacker to exploit.
* The new linker option, -z rewrite-endbr, aims to alleviate this issue. The
linker can carry out a whole-program analysis on the input files to identify
functions whose addresses are never taken. If -z rewrite-endbr is specified,
mold will conduct this analysis and replace the initial endbr64 with a nop for
functions whose addresses aren't taken. (17f0d85)
* mold now produces a more compact .gdb_index section when using the --gdb-index
flag. Additionally, mold now generates a correct .gdb_index section for object
files created by Clang. (a396fa4)
* mold is now capable of handling input sections larger than 4 GiB. (0ce32d3)
* [PPC] mold can now generate executables for POWER10 processors. Previously,
executables produced by mold would crash immediately on startup on POWER10.
(0f71471)
* [ARM64] When a function with a non-standard calling convention is exported, it's
mandatory for the linker to turn on the STO_AARCH64_VARIANT_PCS flag to notify
the dynamic linker. mold now appropriately sets this flag. (2e3b56e)
* [RISC-V] mold now supports new GP-relative relocations. (ac3ee91)
* Tue Sep 26 2023 Martin Liška <martin.liska@hey.com>
- Add build-blake-3-as-static.patch that builts BLAKE 3 support as static library
into mold. The library is not provided in openSUSE yet.
* Sun Sep 24 2023 Martin Liška <martin.liska@hey.com>
- Update to version 2.2.0
* We now use BLAKE3 as a cryptographic hash function instead of SHA256. This
change has made --build-id a few percent faster. libssl is no longer a build
dependency. (7f7a744)
* mold is now a few percent faster than the previous version due to an
optimization of string merging code path. (1a13c50)
* mold now emits slightly optimized code for thread-local variable accesses.
(f057fda, d56f528)
* [RISC-V] mold now supports TLSDESC relocations. TLSDESC is a new mechanism for
faster thread-local variable access. We (@ishitatsuyuki) actually led the effort
to ratify the specification (riscv-non-isa/riscv-elf-psabi-doc#373) and
implement it to compiler toolchain including GCC, GNU binutils and, of course,
mold. (141556d)
* mold no longer marks an as-needed .so as "needed" if the .so file is not
directly used by the output file. Previously, mold marked a .so file as "needed"
if the .so file was used by another "needed" .so file. (f02db0f)
* [PPC64] --execute-only now works on 64-bit PowerPC. (ac20d87, 51fec5f)
- Remove openssl dependency.
* Sun Aug 13 2023 Martin Liška <martin.liska@hey.com>
- Update to version 2.1.0
* Loongson's LoongArch CPU has been supported. (03b1a1c)
* -z nosectionheader has been added to eliminate section headers from the output
file. (084ca55)
* Previously, linking with the -z pack-relative-relocs option produces an
executable that glibc 2.38 refuses to run with DT_RELR without GLIBC_ABI_DT_RELR
dependency error. Now, mold produces binaries compatible with glibc 2.38.
(f467ad1)
* [ARM64] R_AARCH64_ADR_PREL_PG_HI21_NC relocation type has been supported.
(17a5c3e)
* [ARM64] R_AARCH64_MOVW_UABS_G3 relocation type has now been handled as a
PLT-generating relocation to fix an issue when main is not defined in the main
executable but rather in a .so file. (e764557)
* [RISC-V] We now merge input .riscv.attributes contents. Previously, we just
concatenated them. (aa64491)
* Wed Jul 26 2023 Martin Liška <martin.liska@hey.com>
- Update to version 2.0.0
* License changed to MIT.
* Previously, mold could not produce an object file with more than 65520 sections
using the --relocatable option. Now the bug has been fixed. (2e8bd0b)
* mold now interprets -undefined as a synonym for --undefined instead of -u
ndefined. This seems inconsistent, as -ufoo is generally treated as -u foo
(which is an alias for --undefined foo), but this is the behavior of the GNU
linkers and LLVM lld, so we prioritize compatibility over consistency.
* -nopie is now handled as a synonym for --no-pie.
* [RISC-V] R_RISCV_SET_ULEB128 and R_RISCV_SUB_ULEB128 relocation types are now
supported (4bffe26, 1ac5fe7)
* [PPC64] R_PPC64_REL32 relocation type is now supported. (ebd780e)
* Thu Mar 16 2023 Martin Liška <mliska@suse.cz>
- Update to version 1.11.0
* IBM Power10 has been supported. Previously, mold created broken executables for
that target. (5065547)
* --hash-style=none has been added to cancel --hash-style=sysv, --hash-style=gnu
or --hash-style=both. (ec75633)
* [ARM32] R_ARM_PLT32 relocation type has been supported. (e505900)
* [RISC-V] R_RISCV_PLT32 relocation type has been supported. (51845ac)
* Previous versions of mold failed to link some programs in rare corner cases if
Link-Time Optimization (LTO) is enabled. These bugs have been fixed. (e1a7590,
62d6537)
* mold used to ignore dependencies between DSOs. Since this version, if a required
DSO depends on other as-needed DSO, mold keeps the latter DSO as a required one.
This improves compatibility with GNU linkers. (1adde7a)
* [x86-64] mold can now link object files generated by old buggy versions of GCC.
(d2970e0)
* [x86-64] Previously, a program with a very large .bss section may fail to link
due to R_X86_64_REX_GOTPCRELX relocation overflow (#975). This bug has been
fixed. (627bf7c)
* Sun Jan 22 2023 Martin Liška <mliska@suse.cz>
- Update to version 1.10.1
* mold 1.10.0 had a buffer overrun bug that causes the linker to terminate
immediately if compiled with -D_GLIBCXX_ASSERTIONS. We fixed the unsafe memory
access in this release. (7e65546)
* Fri Jan 20 2023 Martin Liška <mliska@suse.cz>
- Update to version 1.10.0
* mold now officially supports the --print-dependencies option to print out
dependency information between input files. Here is a truncated example output
when linking mold itself with the option. There are many use cases of the
option; for example, if you want to eliminate the dependency to some library
from your program, you can use this option to find out all the functions that
use the library's function to fix them. (6fd47db)
* [x86-64][s390x] mold now optimizes thread-local variable accesses in shared
libraries if the library is linked with -z nodlopen. If your shared library is
not intended to be used via dlopen(2) and your library frequently accesses
thread-local variables, you might want to pass that option when linking your
library. (25d02bb, f32ce33)
* [arm64] mold is now able to optimize GOT load by rewriting an ADDR+LDR
instruction pair with an ADDR+ADD if the loaded GOT value is known at link-time.
(f2311b1)
* mold 1.9.0 was up to 10% slower than 1.8.0 on some multicore machines. We fixed
the performance regression and made it even faster than 1.8.0. (7132822)
* Previously, mold failed to report an undefined symbol error if there's a weak
undefined symbol of the same name. That bug resulted in producing a non-working
executable instead of reporting a link failure. Now, mold correctly reports such
link errors. (8936194)
* mold 1.9.0 might crash with SIGSEGV if --emit-relocs is used with object files
containing debug info. That bug has been fixed. (e17d7da)
* Fri Jan 06 2023 John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Enable build on ppc now that the target is supported upstream
* Fri Jan 06 2023 Martin Liška <mliska@suse.cz>
- Update to version 1.9.0
* mold gained support for the three new targets: 32-bit PowerPC, SH-4 and DEC
Alpha. Each porting work didn't take more than a few days for us to complete,
which demonstrate how portable the mold linker is. You can typically port mold
to a new target just by writing a few hundreds lines of target-specific code.
See arch-*.cc files in mold/elf/ directory to see how target-specific code
actually looks like. (651adad, 3411e17, 6231510)
* Bug fixes and compatibility improvements
* In a rare occasion, a statically-initialized function pointer might get a wrong
address in a statically-linked executable. This bug has been fixed. (ccd47db)
* Fixed a -gdb-index option's crash bug on big-endian hosts. (3c96828)
* [RISC-V] mold rewrote machine instructions in a wrong way as a result of a wrong
R_RISCV_HI20 relaxation if the output file was being linked against the high
address. It's not a problem for user-land programs, but kernels linked with mold
could crash due to this bug. This bug has been fixed. (3c96828)
* Tue Dec 27 2022 Martin Liška <mliska@suse.cz>
- 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
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)
* Fri Nov 18 2022 Martin Liška <mliska@suse.cz>
- 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 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 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 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 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 04 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 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 05 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.
* Mon Aug 01 2022 Martin Liška <mliska@suse.cz>
- Add fix-tests.patch which fixes tests on i586.
* Fri Jul 01 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 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)
* Fri May 13 2022 Martin Liška <mliska@suse.cz>

- Add valgrind as BuildRequire argument.
* Thu Apr 28 2022 Martin Liška <mliska@suse.cz>
- Update to version 1.2.1
* 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
as a relative symlink instead of an absolute symlink. (5803c3c)

matching names.
* Sat Jan 01 2022 Martin Liška <mliska@suse.cz>
- Update to version 1.0.1:
* 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)
