mold: A Modern Linker
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.

- Add build-blake-3-as-static.patch that builts BLAKE 3 support as static library
into mold. The library is not provided in openSUSE yet.
- Update to version 2.2.0
* We now use BLAKE3 as a cryptographic hash function instead of SHA256. This
change has made --build-id a few percent faster. libssl is no longer a build
dependency. (7f7a744)
* mold is now a few percent faster than the previous version due to an
optimization of string merging code path. (1a13c50)
* mold now emits slightly optimized code for thread-local variable accesses.
(f057fda, d56f528)
* [RISC-V] mold now supports TLSDESC relocations. TLSDESC is a new mechanism for
faster thread-local variable access. We (@ishitatsuyuki) actually led the effort
to ratify the specification (riscv-non-isa/riscv-elf-psabi-doc#373) and
implement it to compiler toolchain including GCC, GNU binutils and, of course,
mold. (141556d)
* mold no longer marks an as-needed .so as "needed" if the .so file is not
directly used by the output file. Previously, mold marked a .so file as "needed"
if the .so file was used by another "needed" .so file. (f02db0f)
* [PPC64] --execute-only now works on 64-bit PowerPC. (ac20d87, 51fec5f)
- Remove openssl dependency.
