why are we making engineering decisions by executive order? did someone do a broad search for "electrification" and go "HOLY SHIT THOSE AIRCRAFT LAUNCH MECHANISMS ARE WOKE!!!!"

@david_chisnall Also I just noticed that you can (somewhat hackily) impleement a `ptr ? *ptr : default` with like

ld [ptr] #ASI_PNF, val
movrz ptr, default, val

But idk how much of an improvement would this be over just letting the predictor speculate the ptr != NULL case (hopefully NULLs would be rare, wouldn't they?)

When Arm introduced AArch64, they removed most predication. Conditional moves are very useful (and they added a fairly rich selection of these) and can significantly reduce the amount of branch predictor state that you need, but most other predicated instructions aren't that useful on modern pipelines. The cost of an ALU operation is so low that doing an ALU operation followed by a conditional move is still a big win over a branch in a lot of cases.

The one exception that caused a lot of discussion was memory operations. Predicated loads are really useful because you can replace a load of null-guarded things with them: do the null check and conditionally load if the check failed, and avoid the branch.

I've been pondering a few alternatives for a while and one I keep coming back to is a non-trapping load. A load that will give 0 and set a bit in the condition codes register if it would trap. This requires burning a PTE bit in not-present PTEs, because you need to differentiate between not-present-physically-but-present-logically pages (e.g. lazily allocated or swapped out pages), which should trap, and really-not-present pages (which should not trap in this mechanism).

I'm not 100% sure it would be a win, because a lot of TLBs don't bother caching not-present mappings, so you might trigger a page-table walk, but if a non-trapping load were followed by a conditional move, it could retire immediately once the condition was known and skip the load.

I still think there's probably a better approach somewhere.

@david_chisnall The latter part is exactly how the v9 ISA book recommends it to be used (though it uses branches as an example), if my memory serves me right

I dunno how much of an impact it would have on modern heavily-optimizing implementations, though, in particular because those things would already speculate the loads anyway, no?

Halo! Long time no see guys. Well, karena kerjaan di RL jadinya gak sempet aktif banyak di Misskey :satania2:. So, apakah kalian masih ingat dengan projek mangkrak yang akan datang bernama Yorozuya?

Ada sedikit update di projek ini, yaitu tools...

1. Compress Image
Di dalam tools ini, kamu bisa mengompresi gambar dengan output dengan format extension yang sama, namun kualitasnya 90% bisa terjaga dengan baik, tergantung seberapa kualitas gambar yang dimasukkan.

QnA: Bang, saat masukkin gambar, bukannya sizenya makin kecil ternyata makin besar (walau gak besar2 banget)! Itu karena apa ya?

Jawabannya adalah karena algoritma dari library yang dipakai itu sendiri :satania_cry: .

2. Convert Image
Hm.. mungkin gak terlalu spesial banget, tapi di dalam tools ini kamu bisa mengonversi gambar ke format extension yang lain.

3. Video to Frames
Ini bagian asiknya, so aku tertantang untuk membuat tools ini, karena ada pengguna Misskey (pesan2 beliau sudah dihapus) yang memberikan advice untuk tools ini, namun pendekatannya menggunakan server side, namun aku tetap mencoba untuk melakukannya di client side only! Alhasil tetap berjalan dengan lancar dan no lagging (no high RAM usage) di client side.

Jadi, tools ini berguna untuk mengkonversi video menjadi beberapa frame-frame berdasarkan FPS yang dipilih, untuk saat ini aku cuman membuat pilihan 0.5 fps, 1 fps, 2 fps, dan 5 fps.

Mungkin itu saja update dari aku, perlu diingat bahwa projek ini masih local, jadinya aku hanya memberikan update progress saja :)) #animestyle #website #tools #webtools

@koakuma 

SPARC had a few things for working with Smalltalk-like tagged integers. I wonder if Smalltalk on SPARC used this. You could load the values unconditionally early on in a function and then use them after the tag checks.

Fascinating how quickly substantial outcomes were gained: “This study shows just how fast the benefits can come to life. At these two sites, it took under four years for functioning habitat to return. The biggest resurgence was native bees. Around year two, plants began to mature, and that's when nature took off because hundreds of native bees returned to the land. In early surveys, scientists recorded almost no bees, but by year four, they saw them regularly. Other insects as well, including wasps, moths, flies, butterflies, and beetles. In fact, the number of insects surveyed tripled over five years.”

@david_chisnall In SPARC, at least, there's the #ASI_PNF loads that would eat the trap and return zeros instead (though it doesn't set any status codes in the CCR)

I've yet to see any compilers emitting it, I suppose partly cus you can't really tell between a failed load and a successful one that just happens to return zero :char_nachoneko_baa:

@david_chisnall For reasons that I myself can't articulate, seeing how RVC is basically just copies of G instructions But Smaller™ disturbs me greatly

Though apparently they managed to shrink byte counts by a lot so I suppose it does work well?

Though on the other hand I'd also love to see ISA designs that tries to shrink instruction counts instead (while stillbwing amenable to the usual set of optimizing implementation techniques ofc)...

i spent my ADHD power creating a brand new tool to replace boring old lorem ipsum with dog and cat noises.

i call it Barksum Ipsum. use it to add joy and whimsy to places wherever you need filler text.

dog-coded developers need dog-coded tools.
