I've been having a go at improving FPC scores on "BenchmarksGames", and was so far successful with Binary Trees simple by throwing a really good threading library at it, however, there are some benchmarks that simply can't be fixed without either proper intrinsics or user-specifiable inlinable ASM methods. I have a working re-implmentation of NBody (that is just a direct rewrite of the Rust implementation) where I've implemented __m128 and __m128d as records with static nostackframe assembler "class functions", however it's just not fast enough to be competitive due to the inability to inline any of the assembler methods.

Sounds exciting progress for FPC. Btw what happened to the development of “pure” function modifier that would make it possible to use functions in compile time expressions? I was pretty excited about what could be done with that also.
