AMD the compiler code Btver2/Jaguar for performance optimization. Interestingly, Sony plays a significant role here, as the Japanese corporation uses LLVM Clang as the default toolkit for its PlayStation 4. As a reminder, the console is based on a hybrid 'red' Jaguar chip.
Last week, another update was added to the Jaguar/Btver2 target code that reduces latency and improves the bandwidth of CMPXCHG instructions. This will generally accelerate performance. Thus, Sony continues to advance its improvements for the compiler.
In addition to optimizations for the existing console, this may indicate preparations for the PS5's software. This console will be based on a third-generation Ryzen processor with Navi graphics. Given that Sony has already been working on LLVM enhancements for the Zen architecture, this seems quite logical.
It is noted that the current and forthcoming planned changes will be included in the LLVM Clang 10.0 release, which is expected to come out in early 2020.
