LLVM 16.0 Released With New Intel/AMD CPU Support, More C++20 / C2X Features

Also Xtensa architecture (famous for ESP8266 / ESP32 WiFi enabled microcontrollers) support is getting first LLVM patch inclusion.

It'll take a while though before one can compile Rust with a mainline checkout of LLVM compiler.
In the meanwhile the workaround is to download Espressif's LLVM fork.

How does that now compare to mold?

According to mold, lld is slower than mold when LTO is not enabled.

Since mold does not support lto, I'd say that lld should be preferred if your project needs lto.

THe LLVM 16's LLD linker has much faster link speeds for ELF objects compared to LLVM 15.

How does that now compare to mold?

Phoronix: LLVM 16.0 Released With New Intel/AMD CPU Support, More C++20 / C2X Features

LLVM 16 was released on Friday night as the latest half-year feature release to this open-source compiler stack. From initial AMD Zen 4 support to bringing up new Intel CPU instruction sets and processor targets for their new processors being introduced through 2024, there is a lot of exciting hardware additions in LLVM 16.0. LLVM 16.0 is also notable for faster LLD linking, Zstd compressed debug sections, stabilizing of its LoongArch target, defaulting to C++17 for Clang, and much more. Here's a look at all the exciting changes of LLVM 16...
