Log message:
mold: update to 1.1.1.

New features:

- The --dependency-file option has been added. The option is analogous to
  the compiler's -MM option; it generates a text file containing dependency
  information in the Makefile format, so that you can include a generated
  file into a Makefile to automate the file dependency management. (a054bcd)
- mold has gained the --reverse-sections option. If the option is given,
  mold reverses the list of input sections before assigning them the
  addresses in an output file. This option is useful to find a bug in global
  initializers (e.g. constructors of global variables.) In C++, the execution
  order of global initializers is guaranteed only within a single compilation
  unit (they are executed from top to bottom.) If two global initializers
  are in different object files, they can be executed in any order. Reversing
  the execution order of the global initializers in different input files
  should help you identify a bug in your program. If your program does not
  work with -Wl,--reverse-sections, your program depends on the undefined
  behavior.
- --shuffle-sections now takes an optional seed for the random number
  generator in the form of --shuffle-sections=<number>. (8f21cc3)
- mold now supports the following LTO-related options for compatibility
  with LLVM lld: --disable-verify, --lto-O, --lto-cs-profile-file,
  --lto-cs-profile-generate, --lto-debug-pass-manager, --lto-emit-asm,
  --lto-obj-path, --lto-partitions, --lto-pseudo-probe-for-profiling,
  --lto-sample-profile, --no-legacy-pass-manager,
  --no-lto-legacy-pass-manager, --opt-remarks-filename, --opt-remarks-format,
  --opt-remarks-hotness-threshold, --opt-remarks-passes,
  --opt-remarks-with_hotness, --save-temps, --thinlto-emit-imports-files,
  --thinlto-index-only, --thinlto-index-only, --thinlto-jobs, --thinlto-jobs,
  --thinlto-object-suffix-replace, --thinlto-prefix-replace (e413433)
- -noinhibit-exec and --warn-shared-textrel have been supported.

Performance improvements:

- We optimized mold's memory usage by reducing the sizes of
  frequently-allocated objects. Compared to mold 1.1, we observed ~6%
  reduction of maximum resident set size (RSS) when linking Chromium. Our
  maximum RSS is smaller than LLVM lld and GNU gold as far as we tested. We
  measured maximum RSSes with time -v. (f2d27d8, 7068c0c, 83e05da, 4dae896)
- If Intel CET-based security-enhanced PLT is enabled (i.e. -z ibtplt is
  given), mold used to create a PLT section in which each entry is 32 bytes
  long. We optimized the machine code sequence of the CET-enabled PLT
  section, so each PLT entry now occupies only 16 bytes, reducing the size
  of .plt by almost half. (480efde)

Bug fixes and compatibility improvements:

- -static-pie now works with recent versions of glibc. Previously,
  statically-linked position-independent executable would crash on startup
  when linked with mold. (3999aa8)
- Previously, mold sometimes created corrupted output file on x86-64 if
  an input file containing thread-local variables were compiled with
  -mcmodel=large (#360). This issue has been fixed. (4aa4bfa)
- Previously, mold created corrupted debug info section on i386 if an
  input debug section is also compressed using the compiler -gz option.
  (#361) This issue has been fixed. (3068364)
- mold used to create multiple .init_array sections if input files contain
  both writable and non-writable .int_array sections. That caused an issue
  that some initializer functions would not be executed on process startup.
  (#363). This issue has been fixed. (4198627)
- When building a large program with GCC LTO, mold occasionally failed
  with "too many open files" error. This issue has been resolved. (e67f460)
- Previously, mold created a corrupted dynamic relocation table if .got.plt
  is missing. This issue has been fixed by always creating
  _GLOBAL_OFFSET_TABLE_ symbol in .got on any target. mold used to try to
  create the symbol in .got.plt on x86-64 or i386. (eb79859)

Log message:
mold: update to 1.1.

mold 1.1 is a new release of the high-performance linker. It contains
a few new major features and various bug fixes.

New features:

- Native LTO (link-time optimization) support has been added.
  mold used to invoke ld.bfd or ld.lld if it encountered a GCC
  IR (intermediate representation) file or an LLVM IR file to
  delegate the task to the LTO-capable linkers, respectively.
  Now, mold handles IR files directly. This feature is implemented
  using the linker plugin API which is also used by GNU ld and
  GNU gold. Note that the LTO support has been added for completeness
  and not for speed. mold is only marginally faster than the
  other linkers for LTO builds because not linking but code
  optimization dominates. (46995bc)
- RISC-V (RV64) is now supported as both host and target platforms.
  mold can link real-world large programs such as mold itself or
  LLVM Clang for RISC-V. (e76f7c0)
- The -emit-relocs option is supported. If the option is given,
  mold copies relocation sections from input files to an output
  file. This feature is used by some post-link binary optimization
  or analysis tools such as Facebook's Bolt. (26fe71d)
- mold gained the --shuffle-sections option. If the option is
  given, the linker randomly shuffle the order of input sections
  before fixing their addresses in the virtual address space.
  This feature is useful in some situations. First, it can be
  used as a strong form of ASLR (address space layout randomization).
  Second, you can enable it when you are benchmarking some other
  program to get more reliable benchmark numbers, because even
  the same machine code can vary in performance if they are laid
  out differently in the virtual address space. You want to make
  sure that you got good/bad benchmark numbers not by coincidence
  by shuffling input sections. (7e91897)
- The --print-dependencies and --print-dependencies=full options
  were added. They print out dependencies between input files in
  the CSV format. That is, they print out the information as to
  which file depends on which file to use which symbol. We added
  this feature with a few use cases in mind. First, you can use
  this to analyze why some object file was pulled out from an
  archive and got linked to an output file. Second, when you want
  to eliminate all dependencies to some library, you can find
  all of them very easy with this feature. Note that this is an
  experimental feature and may change or removed in feature
  releases of mold. (a1287c2)
- The following options are added: --warn-once (f24b997),
  --warn-textrel (6ffcae4)
- Runtime dependency to libxxhash has been eliminated. (e5f4b96)

Bug fixes and compatibility improvements:

- A PT_GNU_RELRO segment is now aligned up to the next page
  boundary. Previously, mold didn't align it up, and the runtime
  loader align it down, so the last partial page would not be
  protected by the RELRO mechanism. Now, the entire RELRO segment
  is guaranteed to be read-only at runtime. (0a0f9b3)
- The .got.plt section is now protected by RELRO if -z now is
  given. This is possible because writes to .got.plt happen only
  during process startup if all symbols are resolved on process
  startup. (73159e2)
- Previously, mold reported an error if object files created with
  old GCC (with -fgnu-unique) are mixed with ones created with
  newer GCC or Clang (with -fno-gnu-unique) (#324). Now, mold
  accepts such input files. (e65c5d2)
- mold can now be built with musl libc. (42b7eb8)
- mold-generated .symtab section now contains section symbols
  and symbols derived from input shared object files. (e4c03c2,
  1550b5a)
- mold-generated executables can now run under valgrind. Previously,
  valgrind aborted on startup due to an assertion failure because
  it didn't expect for an executable to have both .bss and .dynbss
  sections. mold generated .dynbss to contain copy-relocated
  symbols. The section has been renamed .copyrel to workaround
  the valgrind's issue. (0f8bf23)

Log message:
mold: update to 1.0.3.

mold 1.0.3 is a maintenance release of the high-speed linker. It contains
only the following bug fix:

build-static.sh didn't create a statically-linked mold executable (#315).
The problem is now fixed. (601b9e6)

Log message:
mold: update to 1.0.2.

New features:

- mold now automatically falls back to ld.bfd or ld.lld if GCC-based LTO
  (link time optimization) or LLVM-based LTO are requested, respectively.
  This is a temporary hack until mold gains native LTO support. (a5029d1)
- The following flags have been added: -z ibt (9ca6a9d), -z cet-report
  (31a43a7), -z shstk (e29bd8f), -z ibtplt (fbfa01d)
- [ARM64] Range extension thunks are now supported. Previously, mold
  reported "relocation overflow" errors when the output file's text
  segment is larger than some threshold (~60 MiB). Now, it can link large
  programs just fine. (9287682)
- [NetBSD] mold is now usable on NetBSD. (948248b)
- [x86-64] mold now emits compact 8-byte PLT entries instead of the
  regular 16-byte PLT entries if -z now is given. (0370e7f)
- RELR-type packed dynamic relocations are now supported. You can enable
  it by passing -z pack-dyn-relocs=relr. The good news is that it can
  typically reduce PIE (position-independent executable) size by a few
  percent. This is not a negligible saving because PIE is now default on
  many systems for security reasons. The bad news is that it needs a
  runtime support. To our knowledge, it's supported only on ChromeOS,
  Android, Fuchsia and SerenityOS at this moment. We need to wait for a
  while for other systems to catch up. (bd6afa1)

Performance improvements:

- Version script processor was rewritten with the Aho-Corasick string
  matching algorithm. If your program uses a version script that contains
  lots of glob patterns with the * metacharacter, you'll likely to see a
  significant speedup. (d0c1c4d)
- Relocation processing for non-memory-allocated sections has been
  optimized. You'll likely to see a speedup if your binary contains large
  size of debug info. (d8dc8a6)

Bug fixes and compatibility improvements:

- mold can now link ICC-generated object files with GCC-generated ones
  even if the -static flag is given. (#271, be6ae07)
- mold can now handle archive files (.a files) larger than 4 GiB.
  (bba506d)
- mold no longer have "GNU gold" in its --version string. We had this
  identification string for some ./configure scripts that didn't work
  without it, but it causes other compatibility issue such as #284. Now,
  mold --version prints out something like mold 1.0.2 (compatible with
  GNU ld). We still need "GNU ld" for many ./configure scripts. (cea6a56)
- Symbol resolution algorithm has been completely rewritten. The previous
  implementation was non-deterministic in some edge cases, meaning that
  outcomes from multiple runs of the linker with the same command line
  parameters could be different due to thread scheduling randomness or
  some other internal randomness. Now it is guaranteed to be
  deterministic. (ce5749c)
- mold now try to pull out an object file from an archive if it's needed
  to resolve an undefined symbol with a common symbol. mold used to
  ignore common symbols in archives, so it could fail with an unresolved
  symbol error even if the undefined symbol could be resolved using a
  file in an archive. (27d8361)
- mold no longer converts .ctors/.dtors sections into
  .init_array/.fini_array sections. mold used to convert them but in a
  wrong way. Since .ctors/.dtors have been superseded by
  .init_array/.fini_array long ago, it should be fine to stop doing this
  now. (4348417)
- [i386] mold now ignores some legacy symbols in an i386 CRT files to
  avoid duplicate symbol errors. (#270, 0c19046)

Log message:
Compatibility with NetBSD

Log message:
mold: update to 1.0.1.

New features:

- 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)
- The --threads=N option has been added as an alias for --thread-count=N.
  (f9ff048)
- The following option has been added: --defsym (f6e8006), -z nodefaultlib
  (8c86c28), -z separate-code, -z noseparate-code and
  -z separate-lodable-segments (5601cf4), -z max-page-size (f3766cd)

Bug fixes and compatibility improvements:

- mold now issue a warning instead of an error for an unknown -z option.
  (8bc5736)
- mold previously created a PT_NOTE segment for non-SHF_ALLOC note segments.
  This is a wrong behavior because we should create segments only for
  memory-allocated sections. This problem has been fixed. (76407a6)
- Previously, a version script can affect symbol visibility of undefined
  symbols when they are promoted to dynamic symbols. This is a semantically
  incorrect behavior and caused a libQt build failure (#151). The issue has
  been fixed. (3663389)
- Previously, mold silently turned unresolved undefined symbols into absolute
  symbols with value 0 if -shared, -z defs and -warn-undefined-symbols are
  specified. Even though this behavior makes sense, it's not compatible
  with GNU ld which promotes such symbols into dynamic symbols.
  This incompatibility causes a link failure for Firefox. Since 1.0.1, mold
  behaves the same as GNU ld. (04ccd4d)
- Previously, mold applied wrong values for relocations against Initial-Exec
  thread-local variables. That caused a link failure for Mesa 3D graphics
  library (#197). The issue has been resolved. (d116113)
- GCC 7 has a bug that it emits incorrect relocations against thread-local
  variables under a certain condition. That bug was unnoticed because
  existing linkers silently produces an output that works fine in most
  cases but is technically corrupted. mold used to check for that error
  condition and report an error. Now, mold does not report it as an error
  for the sake of bug-compatibility with GCC 7. I don't think relaxing the
  error check will cause any new issue to existing GCC 7 users, because if
  it does, they would have been experiencing the issue with existing
  linkers already. (d9606d6)
- If an output file has more than one sections for thread-local BSS, they
  were laid out in such that they are overlapping with each other. This bug
  caused a runtime error for programs compiled with DMD, a compiler for the
  D language (#126). This layout issue has been resolved. (b151de6)
- Previously, mold failed to look up correct files under --sysroot in some
  conditions. That caused a link failure for ClickHouse (#150). This bug
  has been fixed. (135f17c)

Log message:
mold: update to 1.0.0.

mold 1.0 is the first stable and production-ready release of the high-speed
linker. On Linux-based systems, it should "just work" as a faster drop-in
replacement for the default GNU linker for most user-land programs. If you
are building a large executable which takes a long time to link, mold is
worth a try to see if it can shorten your build time. mold is easy to build
and easy to use. For more details, see README.

mold is created by a person who knows very well as to how the Unix linker
should behave, as I'm also the original creator of the current version of
the LLVM lld linker.

There's no fancy new features in 1.0. Actually, 1.0 is very similar to
0.9.6. That being said, we'd like to make it clear by incrementing a major
version number that mold for Linux is now stable.

Changes since mold 0.9.6:

- -start-lib and -end-lib options are added for compatibility with GNU
  gold and LLVM lld.
- More ARM64 relocations are supported.
- Compatibility with glibc 2.2 or prior has improved. (#120)
- Compatibility with valgrind has improved. (#118)
- -Bno-symbolic option has been supported.
- -require-defined option has been supported.

Log message:
mold: update to 0.9.6.

mold 0.9.6 is a maintenance release of the mold linker. This release
contains only a single change to fix the following issue:

mold used to create dynamic relocations for imported symbols when
creating a position-dependent executable. That worked fine in an
environment in which position-independent code (PIC) is enabled by
default such as recent versions of most Linux distros. However, it
failed with the "recompile with -fPIC" error if PIC was disabled and
a dynamic relocation was created in a read-only section. mold 0.9.6
fixed the issue by creating copy relocations and PLTs for such symbols.
