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:
devel: Remove SHA1 hashes for distfiles

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.

Log message:
mold: update to 0.9.5.

Highlights of mold 0.9.5:

- In 0.9.4, we changed the mold's behavior on remaining weak undefined
  symbols, so that they would be resolved to address zero if we were
  creating a shared object file with the -z defs option. Now, such symbols
  will be promoted to dynamic symbols so that they'll get another chance
  to be resolved at run-time. This change fixes a regression of Firefox
  build failure (#114), which depends on this particular linker behavior
  to export symbols from libxul.so.
- mold can now be built on macOS. Note that mold is still able to produce
  only ELF (Unix) files — so you can use it for cross compilation on
  macOS for Linux, but you can't use mold for macOS native development.
- Relocation overflow are now reported as errors on AArch64 and
  i386. Previously, such relocations were silently producing incorrect
  output.

Highlights of mold 0.9.4:

- mold -run now intercepts invocations of ld, ld.lld and ld.gold wherever
  they are in the directory hierarchy. Previously, they were intercepted
  only if they were in /usr/bin. This change was made because it is not
  uncommon to install a compiler toolchain into a directory other than
  the system bin directory.
- AArch64 (Arm 64-bit) support has been significantly improved. mold
  can now link many real-world programs including itself for AArch64.
- Fix an issue that relocation addends were not handled correctly
  for i386.
- mold is now able to link LLVM compiler-rt's CRT files.
- Fix an issue that a dynamic relocation was created for a read-only
  section if the relocation refers an unresolved weak symbol.
- Undefined weak symbols are now always resolved to address 0 instead
  of being promoted to dynamic symbols.

Log message:
devel/mold: import mold-0.9.3.

mold is a new linker that is optimized for modern multi-core machines.

mold is command-line compatible with the other major linkers, GNU ld, GNU gold
and LLVM lld, yet it is several times faster than them. Its goal is to increase
programmer productivity by speeding up program build time, especially for rapid
edit-build-test-debug cycles.
