A

Hello friends: if you're watching this life, you are beaming wrong. You should be in this field stream. You should not watch shots, you're, really interested in what we are doing. You can still watch the recording, but we really insist- and you want to ask questions or in the review you're welcome to stay but consider it. What is the build stream? Instead, they are probably more entertaining them all right. So, let's go.

A

We just go left to right, or do you want to go to the 10:00 Monday? You posted in a tenner.

B

So, from top to bottom, with.

A

Because, in the end boom mister.

C

A

B

A

And not see the screen, I thought I shared the screen, I didn't do with teams means I have to figure out how to listen.

A

Tray, he is machine.

A

And I'll select you.

A

Oh, that's right, I, maximize teams again and sometimes when you do that it stop sharing the screen, which is.

A

Most bullshitting Arobin there you go I hope you can associate it I hope you can still see this.

B

A

A

B

A

Are live and get away.

B

This percent of api's, of guys they load a scaler and replicated to every element vector x86, the old broadcast scaler their size.

B

We're matching underlying aiming in terms used by arm ear, so it's loaded replicate and then, of course, adjust the underlying I'm going to pipe the everything except double on you long on both 32 and 64-bit arm level. Unarmed.

A

They're all the same.

B

Yeah they're, all the same, just Odin replicate vector super end alone, a to vector, 1 and then for the end prim pipes. There is no vector 64 version or double along or you because those elements.

B

So there is no.

C

Assume there's nothing better because I understand the argument effectively lots of.

B

Int pointer pointer in it or in you enter any of the vector types. There is April that we extend too, uh but that's on the general backlog and not something okay, as it's much more cuddly impacting.

B

D

B

It just replicates the even valued vector replicate is the term used unarmed and broadcast is next city, some platforms or other.

B

D

There any instance, and instead of listed mode- and these just II replicate they take an aside in the food in.

B

D

Yassir could take it back value, it would just actually load if you call it with an address. You.

B

Can do that optimization for the eight production, but so far for the hardware and there's been an explicit, separate action.

B

D

Coming address believe you.

B

Address system week on uh Dixon with the existing load instructions.

B

A

As I've done and I can't find.

E

A

A

And not in 8-bit, you.

A

All right, so it means I, guess nobody has concerns with this API right.

A

E

A

Excellences of pool.

A

A

Business but hey you.

A

To the next one, you.

B

All right for this one we ah matching as well so far, but these are the I selected, tailor parents, those api's.

B

So it's the same API it should the last parameter: I indexed Taylor,.

B

Picking and use SD other than.

B

A

And they're all the same except some.

B

And I think the OneNote variant is when the selected tailor is a vector of double and therefore the nothing to the name is just multiply a scalar. We differentiate it from multiply scalar.

B

Operate on the first element of.

A

D

Have a multiply skater and multiply by skin. Yes,.

B

Most multiply scalar as act I, write, R, multiplied by scalar.

B

Left zero three left count: I'm I.

B

D

And the instruction there does not take fix.

B

I believe it does, but it can only be because there's only an element vector of double over you.

A

But what's up with all the commented ones, they.

B

Commented ones are ones that we already proved in a separate.

B

So, for example, with multiply subtract by selected scalar. He approve vector, C or by vectors per version. We did not review by vector one version. Also, some ID.

B

C

C

This is just the win adding at you, combination, types and sizes.

E

Written you, you.

F

I have a question about.

F

And by up section it has a right index.

F

I've been ice, elect.

F

B

Yes, or actually that one should a I could have to look, but either it I scaler and it should have right into end vector, shape, double or it should be, or it takes the right index and vector one knee, and it should.

B

It's one of them.

B

You likely to up.

B

And because it would look like.

E

This but for one point, a boat ride right.

F

F

Well, the section below has ice act by ski and match. It has vectors for double rate by Dinda I.

B

Actually, if you at the second group at list that ones I select a learn X, whereas the last one I scaler and it does the operand list as well.

B

B

B

You I don't know without Emily.

F

And make sense, which.

A

One should I look for.

B

That in that very first group, under the comments that the entire group guys there's that easy.

A

B

Oh, that one right below it.

B

The used x add select Hitler that earns double there at one in the very last and Edmunds they're, offering.

B

A

You can fix it. Art Week.

A

Any other concerns, or is that it.

F

I was wondering about some town, looks like a lot of lower down, see multiplier widening by widening her an ad also take Nexus well, but we don't use the by selected scalar terminology. Her name goes.

B

That was like we.

F

I think every blessed.

F

Last five I select.

B

Should be multiplied by selected, Taylor, widening, lower and add I think.

F

Oh, but currently by widening or a net hi I selected, widening.

D

A

And remembering the sentence after you spoke about.

F

Its multiplied.

A

What was it multiplied by Lexus.

B

A

And that should be what instead.

B

I know that that's what.

F

um Broke down a little further right.

B

You blew little bit down.

B

F

I think that one notice there.

B

My whitening, those ones, are miss I selected.

F

Question heard is the pie slick so in all name at the end and go.

A

Yeah, yes, the answer is yes,.

F

Create followers.

A

B

And so the actual production.

B

A multiplication by the selected uhh and then it's doing a widening the.

A

Will to this area should have multiplied, I selected, scaler, widening and add.

A

C

A

Taller granny all right, so then I guess the same is true for multiple widening upper and add. Then.

B

For all of these subsequent here it multiplied by selected, scaler and then the rest of the name.

B

B

A

It's not painful at all.

A

Thank God. We have multi credit.

A

Multiplied by sin.

A

A

You be anything else.

A

A

Like that, as all this looks perfect.

A

A

Easier to have you, um which was the first group, that you.

B

ah That looks you're just missing no fix the first thing there you didn't exceed the add by scalar yeah, one right below so the ad buys the ad by scalar. It wasn't both highlighted because.

A

B

Right about that, that's.

A

This one, you, okay.

A

That won't be name is the one of it or.

D

Changed the one factor when 20 double to Victor, 6 or double for the right parameter and get rid of the right in.

E

A

Surprisingly difficult them, every time you hit enter in this textbox, it Scrolls is like not helpful at all.

A

Being shitty dude.

A

All right, what was it tell me again, a.

F

Chain change, vector.

B

On 28, double vectors couple right and remove.

A

It would be 64 double right and then remove I didn't.

A

A

And the fix with you.

A

Right: okay, bye-bye.

A

B

And then versions without matters.

B

A

I'm inclined to say this was easy, but that would Olivia.

A

All right so then x1.

B

So this is for a polynomial multiply um it split into section. The first ones are generally available anything ransom. They operate I ah they're, similar to existing polynomial. By that we've exposed they just work on. They just hide.

B

B

C

I assume, if you're looking for this, you already know what the polynomial.

C

B

It's basically bitwise patient.

B

A

Anything like that would help me I, don't know what bitwise multiplication you like. If.

B

You go back to one of our pre review, find the diagram that I shared.

C

E

C

I'm timidly, that means, if Wright, has like this right, one and three I'm us times.

C

It makes stuff happen, a big.

C

A

Bitwise means and or and and thing I can do a bit am.

F

I question the I think classes, add arms.

B

That these are.

B

That they are only available if the crypto API is that we, um so the IDI long over are explicitly meant on AES.

A

Level types in the honors.

B

B

A

Picking wood, fencing.

A

A

In assuming a make sense, people, but that's big heavy head- follows it.

A

Right very an odd cam.

A

And if you keep this little Chico, she kills all ten of them. I can't believe it Amos.

B

All right, so these are round picture intrinsics, a a don't, so rounding.

B

Which are a couple issues down rounding ex afloat, truncates or converts it to it, but keeps the vault as where as convert will actually that's basically there. So these are the round one. They take a float, earn a float but dropping actual.

B

First, to hear our ceiling- and they are largely API- is be exposed similar for x86 because they existed in the native entry they're essentially round to positive and run to negative.

B

B

And then or the after that, we have.

B

Similar set of five eight is running much further away from zero nearest negative and positive infinity and to zero. These are used name, aiming terms that we did point rounding the generals, math numeration and also met x86 and elsewhere. They they largely come from e-I xxx back. There are sometimes sometimes they're called infinity, rather than negative, sometimes called ties and ice to zero, there's also the current direction. We expose this API on.

B

X86, but there is no current way on that: no support actually running direction, so it is.

B

And then there's also a variant efferent X, which has found her grounding mode, but it will throw an exception if.

B

Murphy, if the output can't be exactly do not some point exceptions at all net and so and we've got no equipment also.

A

B

Right direction, whatever the current rounding mode at or the hardware on that.

E

Have at mode boost not.

B

Currently bring it, we exposed the same API x86, though post here, in.net, normal operating mode will be the same as to nearest.

A

I would I want to use an oar. This is.

A

It's a good old America.

B

It's a functionality required by the I trip akin to hardware.

C

Right, but why would anyone.

B

Not on on arm is exploiting this.

C

Instruction essentially.

B

It's used whatever the ambient state is.

C

Same-Same statement.

B

Basically, it allows you to write a program at heckling, follows the I Triple E guideline acting exist, running.

C

B

Set I environment, I guess.

C

I guess you're.

B

In mmm bear it nose eyes to eat incorrect due to the inputs being given, they can set the general environment 8 in a a thought. Cosine function that now works correctly under that news.

C

And Aspen Evelyn said of thing and infested exodus is emanated. State XD.

C

B

C

B

Effectively by a generic alcohol rounding out having to go and provide no 5/6 overloads of the method or explicit rounding mode.

B

A

So maybe I missed this, but I'll be doing this, for other is I'm the only one that we expose. This I can remember having a current one for any other.

B

We have it on exit.

B

If we hadn't exposed our on exit shouldn't, expose it forearm until.

G

B

Add support it actually not crash.

A

um I mean when they give you expose it on x86, but, like I mean do we know anybody using.

B

A

We consider this a mistake, or do we consider this every did it and it's fine, that's the thing among.

B

A

B

That has something that has no use. If we ever surrounding modes Durand, there are purple right and it's something that we would Delaney.

B

E

F

B

Rounding it is, but the runtime does up like that. It in you can get into various bad states and asked.

A

But that sounds I.

G

Mean but there really isn't model currently for how you realize that of quite hard wires. So it's something that we nearly at fine art.

B

Takes there'd likely be a lot of work in the optimization layer in SC and everywhere else out for, but the rounding mode is things like that.

A

Like something that is a non-trivial work item, it's not like we're on the on the verge of shipping. This.

B

Right but I don't know if LLVM Otto on ll fiction or unities burst, uh so there's erratically, no Harmonist, yet from exit or runtime allowing people right correct up with at support eventually or if a given variant of.

A

I mean you can come at me, but like I'm skeptical, that somebody can write crack code when they're not able to really acts like it seems a bit like right before.

E

A

Kind of moment I mean like what dr. senator would kind of understand why you would hold earlier, because then it's hard to rev later, but in the context of court, seems like once the feature is there it's trivial for us to expose, like you know, ten more overloads like I would I would generally prefer if we would expose features basically consider when they're ready and not like part of the feature now and then before. You can actually use the feature later right. It seems that kind of a automatic approach.

B

I'm fine with that as well.

A

And so which one would this would just be the current direction? One.

A

After a sneer, only you said that you have some other orbitals that return ins, but they are probably in a different issue as well. Yeah.

B

Found where it says armed.

A

How do we call them.

A

Guess what I'm curious is like? How do you make sure that been call it that the method name is indicative, whether you get back a double or basically, okay,.

B

We have round and I.

A

See, okay, it doesn't get French one descriptive to this.

B

Which matches in role naming elsewhere like on the math class.

B

In the terms that our debris.

A

Anybody else anything or.

D

D

A passed this up already terribly did, but I did agree with the points that you were making that we couldn't expose. Intrinsic people can actually.

B

Well, to clarify they can use, they just can't change. It's not like. We tested the instruction code, but we know that we can omit writing code and everything else.

D

Yeah but I guess.

G

Imagine you can get in a super annoyed way to the right direction. Blending in pictures, I.

G

B

A

It just seems like if I were to use it. I would probably have to test it in both modes right and then it seems like that is something I can't easily do today, but I can only test it in one mode with they see the Advanta machine right. One time works in one mode and if you change to different mode, the runtime doesn't take that very well, but I would assume that customer code wouldn't be any different from man.

B

Oh, the or sealer X. That way we would have to talk someone if Auto ll be as the same. They support a number of things. You don't, in vice versa,.

A

Oh, as you know, what you mean by lobbying did that make sense. I mean yeah. I mean like don't get me wrong like if you have it implement in one runtime like that seems good enough for me, like it just seems problematic to say, don't have the feature implemented like end to end in any runtime. It's just. Basically, we are pre-empting the API, because we do it later that that seems problematic, because in my experience you know a training. Api is almost the hardest thing.

A

We can do it's very customer visible and until you actually have the feature you know you're saying: okay, we know we know what the encoding is. So it would be trivial and you're- probably right with this, but it it just seems always kind of problematic to do the second step before the first and it does I, don't see any downsides with doing I.

A

Guess that's why I'm just leaning towards just let's just do it when we actually do the rest of the feature work, but if the mano guys say oh, we want to have this and I would not be a posting. The same.

B

So maybe we everything except for a current direction and then I have a follow-up item to talk to ah no the if they support this and if they do and it is into the move, no one has an issue with the daemon. If not, then we just posed it until some runtime does yeah.

E

A

I'd be shocked to they cared, but.

A

A

A

I'm, like 20 tabs Oh.

A

A

A

B

So these ones are load and I load. A a scalar value from the given address heard it in value at least five, so it's essentially owed- or it basically insert, but with explicitly coming from memory rather than a a general register. A.

B

A selected other.

B

The ordering parameters here matches d, +, +, +, I called out very bottom. You might want to ordering it Value Index address. Instead, as that matches, sembly instruction takes and the order used by the Persians.

A

Doing other instructions, we generally follow the instruction on the e.

B

Right well, most of the time they like this, but we previously tried to order in relate construction.

B

It will be a pointer and regardless Jews or some.

A

When the general rule-of-thumb balls, we want to expose the intrinsics as they are represented by the utter manufacturer right, and it also why we have aim of the intrinsics and whatever link we have for the docking.

A

Would make sense to me HD.

A

A

But I feel like if you, depending on what Cody reporting.

A

F

Having it is, never Israel.

A

F

A

That the types of, if it doesn't compile it's fine for as you would write.

B

It comes from, they might expect ah peep API to largely or the parameters, but for these ones they have to twelve you. It just makes order.

F

You I'm confused they're porting from us and orders already perfected.

B

Right but I had called autumn I want to call you in a dress. Instead, who match the ordering of the insert intrinsics that take it by value and to match the ordering that action take as the instruction take value.

B

A

um This to me patience a bit off.

A

B

This is basically a May P I, but rather than and same thing, the B plus plus index address value index, but the introduction value.

B

B

Should basically ear copy, but voyage return, rather than its store.

B

A

A

Like a no-brainer.

A

B

This is basically equivalent to found API, but rather than earning returning a float, they return integral Oh convert to in 32 and convert to or and then rather than just doing away from zero and two negative and because convert two and thirty to negative infinity.

B

Ding I pre found, though number 2 in 32 and away from 0, and confer 2 and 30 around to negative cetera.

B

A

Oh, this is my mental.

A

My pain capabilities are not that sophisticated. It is literally the same thing as before, just with convert to introduce you basically for the Indians, it's.

B

Basically, name there's a couple of very bottom that do be River added, integral loading point types and those are called convert to double or two.

B

A

A

F

I'm just curious: do we have any guy sitting types like you 32 doing 64 in their name all.

B

F

B

That's it the conventions to match the framework name rather than language name,.

A

Then the most popular one is convert to insects like they're. Just usually method calls right. It is your steady convert, class exorbitant.

D

It's called convert and 32 and the fourth without the rounding.

A

No, there is a method called to n32 on a static class called convert that you did the pattern right, but, like the usually on on a on an object, you would have it to xxx.

D

Yeah, but you have any or blast vector fix that our convert to 32 for those ass.

B

These are the api's that.

A

Okay, so these are on them, not Castro.

B

B

The reinterpret guys all as and they're they're general-purpose are more exiting.

D

A

When the question is does convert by us much right, because I didn't using the frame right, we just call things too and then act that it's to implies. It's a.

D

Well, we have like dirt, but in this case part of this MD, so yeah.

A

For convert, that's true, but I mean convert really. The only thing that this time does is the as the actual conversion. Right, usually, you have a type and then say like, for example, an array you and I lied on I, never believe it extension method called two lists of T right or right, but.

C

The when and is the verb always applying on it, it's just a static, so having to convert is converts simply an implied verb.

A

I guess that's fair right because.

B

We also convert 4x6 and it's the that lying instruction has.

A

B

Be one thing of note convert remember from integer to floating is there are a four variants deal with, but the ARM architecture made and you'll expect, ah which seems to be armed, 32, civic and finished being able stand how it worked, and those are right now.

B

B

From from what I can tell as effectively take a 32, for example, and then they encode in the where the decimal point is in that and they use of basically.

B

A

My team's unusual we're also not all.

A

I'd, like you.

B

If it required I figured a bit more I thought in process and.

G

B

How it works, therefore, how it should be.

A

And the most obvious thing can think of, as you make the parameter.

A

Then you have the same problems that you have of all of these guys, but.

A

On the beach and simple you could also I mean, given that you know I mean I, guess for a 64-bit. There would be this bad for 32-bit having actually 32 over those, but not so much.

A

Well, when you have to actually have it as a parameter, light stain.

B

A

Like to switch statement yourself.

A

You I think parameter would be fine.

A

A

Even the fog I.

B

A

Else, or is that.

B

A

You once done beautifying.

A

A

A

A

A

Really wish there was.

B

B

This is just a X miscellaneous guys that work, yes, not cover other Purple's up.

A

In Romania northern.

B

This is simpler, x1 has some crazy names.

A

X1 okay moment: that's how they.

B

A

To actually finish in the best.

B

Vote. The first group here is a just variants of absolute, which we call just a be a matching name, but it saturates, the rope and rather than earning unsigned result. That's right, I'm right.

B

So if you trying to come on.

B

A short thought meant, for example, act short.

B

I think you get back short time. This hatchery.

B

A

We usually use the saturated, do we didn't we say, hands.

E

B

This is the case where, on x86, just the firm saturate, not saturating anything and we've carried that over armed, so.

A

You I've literally no idea, you can remember all of this.

A

A

Yes, somebody hit the table.

B

And the next is convert api's, they're, basically similar to inverted api's. We just except they convert from float to double and double so they're, essentially widening versions here or double it is widening conversion, and so there's lower and up operating on the respective halves and since there's no vector 256, it just returned.

E

Isn't care to double or accept.

B

That's not how the Under.

B

We could expose, we could expose just a convert to double that took Oh.

E

Because it looks like a pill as management who else possibly put the spoon full.

E

B

Because there's only one, if you look at the company.

B

Then bin eyes be the only sub uhh, the I guess it does.

B

It should or a.

B

You so so there should be another variant. Then invert few double takes a vector, see.

A

B

And returns a vector one.

A

That means more than just an old.

B

B

G

B

To or postfix that imply you're only reading, lower 32 element.

A

Yes would be converse double X back to 60 in.

B

Returns, 120.

A

You amazon also trooper in okay,.

B

Yeah yeah a single airway, so Oh after it's a turn.

B

Taking vectors and the second version.

B

E

I guess we always upper ethics or on decoration near the system like, for example,.

E

Normal by yes, oh by the knee, we also remain lower and upper all the import based on first or second half ready to import convert to bubble.

E

If a person who would know the decoration vector, C or or upper.

E

B

But that, but what's that.

E

Because I thought the draw.

B

Or the variant except actors you can't use because.

F

B

Because that would imply would be 100 other than higher back so we'd have convert to BB for load and then convert to double vector. One negative.

B

E

Remember, history, recreational all vectors, or course Olsen the at before. So this is how we imported upper with extra month, which is Hungary upper.

E

Yeah there is a a widening.

E

Reitan vectors or being returned vector 120 is wrong. There is also by widening upward.

E

Bill Vickrey from 51.

E

Only read yeah is.

B

Yes, that's a general gaming, because also it's not that lower-half I, don't think that onward apathy all its returning, our one. It's a sector fifties that would end up being person.

E

Sometimes mixing bond by on construction basically operates on either, first or second.

E

And Brazil by the name, good journalism upper hose national nervous.

E

Both cases for an upper.

E

E

As we come, follow up with it'd be clear: they're like keep lower or open this one. Now we can call.

E

D

Victor sewed businesses.

B

That's by general.

E

That's what we're using error by firstly well,.

B

Scaler means for only the zero.

F

B

We're taking a vector see same as right.

E

B

We're not taking work. The result is always a vector one native, so you're, taking the variant taking both loads and converting it to judo in a vector one, whereas with the convert to double lower version taking in for float only taking the lower two in convert 28 and with upper you upper to pepper.

E

Pepper Ector one, but we actually need we were to double lower rates on April 1 2012. But you can get get over.

E

Oh that both could.

B

Do that with them eyes we had Phoebe's said we would be exploited to avoid people needing to insert the I get lower, vector, 1:28, unsafe, api's.

E

E

So it looks to me: let's be August: oh thanks for reading. Not exploding works differently.

B

If there's ones that are missing should probably act, a list of the that week follow up and make darkens yeah guess.

E

What pictures practice.

A

B

I'm sure, tired.

A

I mean normally I would say, the radio DPI review is for us to actually check for that problem. Here is that there are so many names that, unless your domain expert here very unlikely to find this.

B

There's 2002-2008 guys tool so I'm sure we've we've made some minor mistakes we've caught and we fix highly plausible that there will be some that won't be caught until customers using it and probably couple that shipping with by accident, realistic.

A

Yeah and honestly, this is of the Arabia I'm I'm, not fine with that.

A

It's never great, but not terribly.

A

But then, which ones I'll be following up is just the poor thing.

B

Yeah, it's the usage of lower and upper and if there's any place, we've or the instruction intake twenty-eight and we've only exposed on version requiring user castes.

B

E

They don't see a word from the pig or float.

E

Welcome start other than convertible upper bill, but under to the below or yes all right for waving, promote or.

B

There's a native API that.

E

Give me likes it.

E

B

Nope, just the one that returns hi, that.

E

Oh yes, yep go somewhere. You you, you.

E

Hitler's one oh I,.

E

B

And the other takes 32, but it's labeled, I yeah.

E

The upper resolve, along with both see supporting they, are drunk, see, x32, pipe or hi.

B

Okay, in that case, we have one- that's not named.

D

D

Other proposals like get rid of vector, 128 or have a vector 64 version.

B

D

And there's another way: let's wait were explicit to convert from vector one.

B

You have to do not get it's an extension.

D

You in I've heard several time try to be very explicit about.

D

Allowing people to express and then hoping that the optimizer does it for them.

B

D

It was that logic.

B

In in the case,.

B

In the case of get lower, it's a no off unless the register allocator.

B

Either because it needs it because the mother canario but vector 64 and vector 128, unarmed 60, represent the same under.

B

B

And so it's possible a gaming. This wrote it correctly.

B

B

So then it just becomes a question of: do we want to expose area, X, Factor, 1d8,.

E

B

Is the vector, C or just match what the underlying actually actually and only take pictures.

B

D

But interest actual action sports.

E

I agree, otherwise both many more overload other.

E

E

Here's a question it'll be named, convert of hybrid some point type of toxic in then we can just do name use a vector C world in our type as new.

B

That doesn't H without we've numbered AP is with aim to for clarity, so I would say we would just expose to single that takes. It need up happen.

B

A

B

I think that's everyone.

B

B

But that that's only there's more api's in the I just meant we were too.

B

B

B

The next ones in extract arrowing or saturate.

B

Crack narrowing upper saturating and then back arrow, lower saturate, Burberry, II, signed versions, or they always return to sign up, but they something signed or unsigned, whereas the unsigned Barry always return unsigned. Taking.

E

Who they are of.

B

I put it s Allah, because.

B

The order of operation tracks arrows the upper or high half actually ensign, didn't any world. Maybe it may be a.

E

E

Or result an uppercut.

E

Or person lower part filled it up.

D

Right this case, instead of storing in the path distracting.

B

It extracts facts.

B

E

Think it excites on my behalf over like a snare of3 from all the raid on cyber and while for it either power.

E

HM This waving you round up or okay.

B

It reads: each vector element that rates the value after vector writing to the.

E

You and, if suggests, lower opera.

B

B

You arrow arrow in battery.

B

Back there that's right.

E

B

So that's, it can be exist, a man just upper and lower to the end.

B

A

I was just responding to somebody's tweet was the conclusion here.

B

It the upper and lower keyword, that's in the book of the API and move it very end.

A

Basically extract narrowing the traded sign.

E

E

E

A

E

E

A

People are people live, the vault occurred in it.

A

You if so the only usage.

A

E

What is this Detroit sign? It looks like there is a person, because there isn't right yeah, it does iterating.

B

You completely right es sqt exit sign, there's X, X X takes unsigned and then.

D

E

B

E

B

Don't know that on that and then there's xtn which exams grandson there isn't a variant takes on.

E

B

E

And I paid valuable I mean.

E

E

Assisting construction or concept basic reserve, the time fine unsigned.

B

Okay, then I just got the rich.

E

It looks like we need, extract, nearing or virtual rate bug, earring or the trade unsigned.

E

First, one through the grate on both sides. First point rated value great on unsigned unsigned. My I do for ten marks, like it's a very fun time, I a great unsigned, responding, unsigned value.

B

So just the api's that take on in return signed could be under the second.

E

Yeah but I don't think we need this I picked them this time.

B

We do because variants excite exciting month.

E

B

Can't old sign and.

E

Return us and ensign Patrick, so the tape and unsigned picture.

B

E

Sign to add in perfect pairing such.

B

Anthony's just exit clear, if you have.

E

For consistency think this was shifting, is it whenever used and probably do the only used unsigned.

B

We post fixed, arithmetic and lob.

E

Prospectus logical, adequate.

E

Just because we decided on time Pirlo, if is podrick right, I think.

B

All the saturation.

E

Yeah we'll be clear: Blanco.

E

E

With unsigned four and five course.

E

I'm going to saturate to Einstein.

E

You basically is fixed and and cook.

B

E

Of having I think yes are, we go only s x2 n.

E

B

E

Explant betrayed.

B

That would be science.

E

You next round.

B

But instead I think this entire compute by just having the suffix generally better, because then it just tells you returning unsigned, you don't have to look up, you don't have to guess.

B

/ EPS you feed edit unsigned and returns on, find the line and.

E

I guess it proposed all that we need Patrick's, eight or apps okay.

E

B

They're potentially, although negate.

B

You just absolute find.

B

B

So maybe we should just mark the extract narrowing you should come back after it and how to set find versus find unless someone wants to right input.

E

E

A

Did I miss some conclusion right now.

B

Sounds like us, extract arrowing and bring that.

A

Means they just remove the extract narrowing one of the lower in the upper.

A

And that includes saturated, well, rent.

B

There's only saturate.

A

A

A

B

And then following that, then actuary.

B

Which is just the gate, but it returns a saturated alt to account for.

B

B

And then for underarms.

B

Saturate at rate variance all.

E

Negation iteration worth what I have by.

E

On point and finding cases on saturate.

E

I'll sign right.

B

So it explains a sign result, but the API said.

E

And in return one point.

E

B

E

B

It returns either end up returning I thought max well, I mean I'm, not sure which.

E

I see the sign.

E

Returned one point.

E

B

And then there's add across heightening.

B

ah Just ads across.

B

B

B

I think I must the return type should be nice parameter.

E

Human elements over it here concern together the.

E

It's on awesome, you.

B

So these are slightly different from the pairwise. They a wide I, don't believe we have at pairwise.

B

No, we did or or the.

B

Long yeah for the EULA.

B

It would be the same as their wise.

B

And it because that overlooked, unity.

E

And same for long go on general.

B

B

Mo it's where it says, buy for the return type that should short and where it says short that should be in tan in should be long.

A

The sort of the Vectra signs of exercise should be 128 is a way that.

B

E

B

Return type should always be.

A

Talk about negate cetera.

E

Oh, it's at the cross waiting.

A

Here you go load them.

A

A

A

And then you said, byte is going to be too short almost.

B

Done at that works.

B

A

So Jeremy is eating with norm and hungry myself.

B

B

So so it's the named API basic earned, type server, 60 and the element type that's twice the size input, Oh bite becomes short short becomes in long as piety sure.

B

A

A

I wish all right.

A

A

Once right and.

B

Then the next similar so there's youth squad and and new quad X in a left parameter in the desc. Fine right parameters, kind of the skin wit and then you squad is left, run sign.

B

B

E

Listen and before.

D

D

D

Based on first.

B

The result is they miss the first ammeter type, but the right.

B

B

And then very last guys are convert to single.

B

Double but they found rather than bounty.

B

D

Elsewhere, you listen, I called out and same.

D

Or which ones and century.

B

So because the result, there's no ambiguity. In put so far, the only place a be needed signed run, extract narrating because there are some over conflicted after differentiates, but your and I are going to just that offline turbine. Whether the tough example should be all of those only on variance that a union.

D

I'm, trying to think of there are initial errors, also adds this extra pop left and right values in a different type.

B

Unless three far.

B

B

But I think this is also along the lines of thing earlier with there's other overloads like ABS, which take signed and returned signed versus, Absa trait, excited and returned. Some air might have some.

B

A

Yeah to me, it's kind of reward.

A

Make some things easy make other things harder, but trying to me I feel like. If you want to be listed with these api's, then eventually like every single entrance, it becomes a paragraph.

A

We are already halfway there anyway, but like this.

A

Sometimes, if you like, maybe it doesn't.

B

There's there's a lot more gotcha beyond just the name, I'd hope anyone using already instead I correctly testing in profile anger, hopefully at shoes.

A

We we should suffix all api's with NB care.

B

A

A

A

B

Oh, it's the same at purchase single at the top rounding.

B

Which basically have a result that is exactly halfway represent bolts. It will choose uh odd, it's all, rather than.

B

A

I may have made my life hard again the thing my note still only picks up comments that are close to her: a change within 10 minutes by 426.

A

Unwin here this capture, everything we said, though,.

A

E

B

The convert to double.

B

We said he said so we just that 1:28 version always.

A

B

The power one agent.

A

The other one is just just a replacement.

A

E

Right maybe over there.

B

And then we've got one, the other one I just looked at is actually doing live.

A

B

Because that's that's one, a basic couple of elements: two three or actors at living: Jewish register. Oh it's.

E

Not about this for there, but arbitrated doesn't care for pregnant okay.

B

Ooh one that does shot one then.

E

It's one of this clarification: how continues register xposed framework.

E

Working our site for store beer, certain book club, but not then.

B

Then we've got to.

E

There is a hole, bigger I proposed, yes, I.

B

Wasn't sure like.

E

If one is Apple and Valeo.

E

E

A

What I'm hearing is that is one more meeting.

B

That's only maybe.

A

We get away with one.

B

G

B

Sounds like we just have version. Maybe this and.

B

The feedback up.

E

I'm sorry, zero, meaning of all those auditions register, one of them Apple other special Specter excellent link, Ford Explorer, because we need to show you them all. A by women punish this book.

B

Sounds like one more meat should be.

A

Yeah so Kadena was thirsty of you will look at HTTP again, um I should say sis the net connections and.

A

Something tells me that we probably also need one more for that one, I, probably, and then my days of next Tuesday. We can then decide whether we do they're full up to the system that actions one or the armed.

B

I think Igor and I could probably resolve the remaining questions about the I spy. If Igor thinks well.

A

E

Trainers over in this variant, all right.

A

That works I mean just. Let me know.

E

A

We can, we can decide late minute, I get it. He just had this lot and then people always fill it with something. My first case, you reviewed the backlog.

B

Never happened.

C

The Germans with comedy.

E

C

A

B

For this one in particular,.

B

Was a question uh basically for the the api's here: aim: I think it's I, don't know where we should put I select a l'heure. You were in that group if any this last minute. Last four minutes. If.

A

There's strong opinions, you should put it in the right.

B

Great, where is the right? It's.

A

For you to figure out dinner, shouldn't.

E

Be multiplied up this weekend and Irving.

E

You know you're after.

B

B

Thank friends in need, nope, never mind. I multiply doubling.

B

And I can fix that, but let's necessary clarify word: isolate Taylor.

A

Right after that makes double-click allure.

B

A

Instead, what we just did we just by selected Skinner, also.

B

Oh sorry, I know, I, know, I know it's it's a.

B

So we've got the doubling x, s-- x, selected, 8 hi. These are scalar by scale taylor by select so it it multiplies left eye.

E

B

So when you have, when you have both allure and by Taylor,.

D

I should be multiple error.

B

Yeah, the one can one downside is a l'heure suffix.

B

B

Maybe that's not too bad.

B

You seven ethic.

B

B

And I will this proposal we can mark store pair is ready for it up the load pair with the meta art about how to return and take multiple factors and then.

E

There is one more ice Maur host the product iteration or the compounded.

E

Prolific bloggers are again before this.

B

I think what it was on the general backlog in the goal for advanced MD and what's important.

B

Many anything else is icing because we got Albin desired stuff done and we.

B

D

The meeting is you.

E

It's tomorrow, night Oh.

B

I believe the invite normally and on the past and on them, but he's also in London, so I'm not sure what I'm it him.

E

A

A

Be good for the day, then.

B

Think that's everything.

A

For the rest of the week stuff.

A

B

A
