New Intel Tremont Optimizations Heading To The GCC Compiler
The new GCC Tremont patches include updating the memcpy/memset inline strategies, updated handling around vector and SSE conversions, switching to using the Haswell scheduling mountain, enabling a number of other options.
What's important is the end result and with these four patches touching just over 300 lines of code is around a 1% improvement for SPEC CPU 2017's INTrate performance but around 7.5% higher FPrate.
These Intel Tremont improvements for GCC are currently available via this patch series while should be mainlined soon for GCC 12.
