mold: A Modern Linker

Edit Package mold
https://github.com/rui314/mold

mold is a faster drop-in replacement for existing Unix linkers.
It is several times faster than LLVM lld linker, the second-fastest
open-source linker which I originally created a few years ago.
mold is created for increasing developer productivity by reducing
build time especially in rapid debug-edit-rebuild cycles.

Here is a performance comparison of GNU gold, LLVM lld, and mold for
linking final debuginfo-enabled executables of major large programs
on a simulated 8-core 16-threads machine.

- Update to version 2.33.0
  * mold gained a new linker flag --separate-debug-info to bundle debug info
    sections into a separate file instead of putting them into a main output file.
    You can optionally specify a filename in the form of
    --separate-debug-info=<filename>. By default, a debug info file is created in
    the same directory as the main output file with the .dbg extension. mold embeds
    the debug file's filename into the main output file so that gdb can
    automatically follow the link to find debug info when debugging the main output
    file.
  * The main objective of this flag is to speed up the mold linker even more. By
    default, mold creates a separate debug file in the background after creating a
    main output file, so that you can start running the executable as soon as
    possible while mold is still working on linking its debug info sections. For
    example, linking clang with debug info normally takes ~1.70s on a Threadripper
    7980X machine, while it takes only ~0.52s with --separate-debug-info. Shaving
    off a full second in quick edit-rebuild-run cycles should improve programmers'
    productivity. If you do not want mold to work in the background, pass the
    --no-detach option. (596ffa9)
  * mold now supports the --no-allow-shlib-undefined flag. If the option is given,
    mold checks if all undefined symbols are resolved not only for input object
    files but also for shared libraries passed to the linker. To use the feature,
    you need to pass all shared libraries, including transitively dependent ones, to
    the linker so that the linker can resolve all symbols that are available at
    runtime. (3001f02)
  * mold gained the --dynamic-list-data flag for the sake of compatibility with GNU
    ld. If the flag is given, all data symbols are exported as dynamic symbols.

  * [x86-64] -z x86-64-v2, -z x86-64-v3, -z x86-64-v4 flags are supported. (5606087)
  * [x86-64] Recent x86-64 processors support Intel CET to protect control flow
    integrity. When the feature is enabled, the instruction that is executed
