cmd/compile: generics add significant build time and build size overhead

Sure.

cmd/compile: generics add significant build time and build size overhead

Likely closely related to #51957 .

cmd/compile: generics add significant build time and build size overhead

@mdempsky This issue would at least be partially fixed by moving away from self-contained object files. Thin object files might help with the cpu, and almost certainly would help with...

runtime: CL 501976 performance and jitter regression

I need some more specific instructions to reproduce. So far: ``` git clone https://github.com/JetSetIlly/Gopher2600 cd Gopher2600 git checkout d1482c139ab9c78b18902426e87367a58cf8b101 ~/go1.22.0/bin/go build ``` That last build produces some strange results: ```...

runtime: CL 501976 performance and jitter regression

I am not seeing any significant performance differences between 1.21.6 and 1.22.0 (and tip, for that matter). There's quite a bit of noise in this benchmark, so it is hard...

runtime: CL 501976 performance and jitter regression

> If we take an average of the runs for 1.21.6 and 1.22.0 then there's a drop of 1.86% in performance. Sure, but the run-to-run variance can be as much...

cmd/compile: stack overflow when typechecking self-referential types

@griesemer If I understand correctly, this should be rejected by the typechecker and not reach types2, right?

cmd/link: lock down future uses of linkname

We can't fix what we don't know about. > 4. As we get reports of additional breakage we missed, add more //go:linkname annotations to the standard library. We're open to...

cmd/link: lock down future uses of linkname

> It would be nice to have a flag (maybe in -ldflags?) to allow "pull" style //go:linkname. The proposal says: > Note that anyone who wants to experiment can always...
