- Update to version 2.31.0
* 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_ and __stop_ 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)
* 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.

* 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)
