"This is getting out of hand! Now there are two of them!"

Today at the @berlincreators Retro/Amiga meeting, we spontaneously managed to pull off the first ever Mirari PowerPC User's Meetup! ... At least in Berlin. But maybe globally? 😅

It’s that time of the year again - someone (me) wanting to try replacing #gentoo ‘s #portage with a #Z3 #SMT solver. Well, this time I did it! Or at least started to… got 2x performance boost but it’s not quite black and white.

@david_chisnall @zkat @xgranade Regarding the branch predictors: you could avoid them completely if OS vendors did not pretend they are writing code for PDP11, and CPU vendors did not have to cover up that their CPUs have a pipeline.

Branch delay slots are well known technology, and compilers are completely capable of loop unrolling and filling the slots with instructions that are useful.

Exposing the fact that the CPU has a pipeline avoids the need for statistical branch predictor as well as it avoids multiple forms of Spectre vulnerabilities.

There, solid solution without use of AI. Unfortunately, for reasons outlined here https://archive.org/details/lca2020-What_UNIX_Cost_Us solving problems is not viable, only papering over them is. Reasons boil down basically to entrenched industry inertia.
