New:
- mold is now up to 10% faster when linking very large, debug
info-enabled executables such as Blender (~1.8 GiB) or Clang (~3.8
GiB), thanks to several improvements we've made to the string merging
algorithm. (53ebcd8, d714301, 40f6b17, c9faf3d)
- -z start-stop-visibility=hidden is now supported so that
linker-synthesized __start_<section-name> and __stop_<section-name>
symbols can be completely hidden from other ELF modules. Previously,
only -z start-stop-visibility=protected was supported. (99a5b15)
- -Bsymbolic-non-weak and -Bsymbolic-non-weak-functions options are now
supported for compatibility with LLVM lld. Just like lld, these options
control which symbols are exported as dynamic symbols.
-Bsymbolic-non-weak makes the linker to export only weak symbols,
whereas -Bsymbolic-non-weak-functions makes it to export only weak
function symbols. (7d17aa8)
Bug fixes and compatibility improvements:
- Previously, if a linker script contains a newline character in the
beginning four bytes of a file, it was not recognized as a linker
script by mold. Now, mold allows newlines at the beginning of a file.
(ea054cc)
- Under rare circumstances, the INPUT linker script command may have
found a different file than GNU ld would. Now, mold's behavior aligns
with GNU ld's. (163975d)
- Previously, the --repro option produced corrupted tar files. Now the
bug has been fixed. (32c4a09)
- mold generally guarantees that its output is reproducible, meaning that
if you run the linker with the exact same command line options and
input files, the output is guaranteed to be bit-for-bit identical to
the previous outputs. However, under rare circumstances, it might
produce different output due to a bug. It's reported that this
nondeterminism caused random crashes for some programs (#1247). This
bug has been fixed. (6463a7c)
- mold no longer sets the address of the .text section as the entry point
address if --entry option is not given, just like LLVM lld. (020b1a7)
- [RISC-V] __global_pointer$ symbol is now exported from executables as
required by the processor-specific ABI. (3df7c8e)
- [ARM32] --long-plt option is now recognized as known option by mold.
mold ignores the option, though, because the PLTs generated by our
linker is always long. (d432e98)

v2.0.0:
- transition from AGPL 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.
- 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)
v2.1.0:
- 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)

mold is a faster drop-in replacement for existing Unix linkers.
A single binary is able to link various targets, which is why this lives
in tools/.
All toolchain builds then just need to copy the linker over, hence avoiding
multiple builds with the same outcome.
