Dear all, I just have a short question regarding the forecasting of ARIMA models with external regressors. I tried to program a ARX(1) model arx.mod <- arima(reihe.lern, order = c(1, 0, 0), seasonal = list(order = c(0, 0, 0), period = 52), xreg = lern.design, include.mean = TRUE) for which I need to estimate the next (105th) value. Xreg=lern.design is - at this time - 104 rows long. I

for example I want to insert a new machine bb “before” a specific machine bb. or split a mbb and keep the later one as the original one. (to keep the label/Blackadder's correct t) (or keep other property of mbb) so I need to transfer the original mbb's predecessor to the new mbb.

Conditional on the target supporting cmov? Though that's probably not optimal.

This might give us a hint about what other frontends might expect, and who needs to be involved in the discussion (if one is needed). Cheers, Nicolai > > On Wed, Aug 22, 2018 at 11:41 AM

Any comments at all on this? Chandler perhaps? I've since dug a bit further, and it seems like the template-based solution wouldn't work anyway because DLL loading on Windows can't do the required commoning. So the general approach taken in https://reviews.llvm.org/D62802 seems to be the only technically viable path forward, though it would still be good to get an outside look at the

Hello, I''m a newbie, coming from Visual FoxPro - a database centric and object orientated scripting language with a rich set of graphical user interface controlls. Lerning ruby on rails means for me to lern html as well. But now to my problem: The validation errors are listed at the top of the page without any order. Depending on the size of the form and the numbers of errors listed the data entry fields containing the corresponding invalid data eventually are o...

Hi all, We’ve been having discussions over the last few weeks with stakeholders both inside and outside of AMD about where we could best have a dedicated and open discussion space for topics around the AMDGPU target. The conclusion was that we’d like to try the use of a category in the LLVM Discourse group, which is mostly used for MLIR discussion so far. I have started a Discourse topic with

Hi Craig, The review for the similar GPU problem is now up here: https://reviews.llvm.org/D85603 (+ some other patches on the Phabricator stack). >From a pragmatic perspective, the constraints added to program transforms there are sufficient for what you need. You'd produce IR such as: %token = call token @llvm.experimental.convergence.anchor() br i1 %c, label %then, label %else

We've relaxed `atomicrmw xchg` to support floating point types but not cmpxchg -- the cmpxchg comparison behavior is not a floating point comparison, so that would be potentially misleading. I'd say adding the assertion is a good idea. Cheers, Nicolai On Thu, Aug 13, 2020 at 10:59 PM Chris Lattner via llvm-dev <llvm-dev at lists.llvm.org> wrote: > > Does the code generator

Are all the records collected as they are parsed, with template parameter substitution and lets, and *then*, after all records are collected, a "pass" is made to calculate the inter-field expressions? Once I understand this, I will add a section to the new guide to explain it. I presume it is the case that this behavior should be publicized. It also appears to be the case that a record

Nicolai, Can you do without the use of -fp-contract=fast (Options.AllowFPOpFusion == FPOpFusion::Fast ) and without Unsafe? As I SPIR-V’s usage of NoContraction flies in the face of both. If so, you should be able to get what you want, as then you are down to just IR flags. You will need a model to generate the correct behavior though in your SPIR-V implementation wrt IR flag emissions.

Yes, I understand the problem. To be more useful, TableGen would have to carry the traces along with the classes and records and (re)display the values while the substitutions are being made. I'm writing a new Programmer's Guide for TableGen and have been digging into the parse-time versus substitution-time issue. I haven't found a document that makes it clear. Can you give a quick

Hi Nicolai, if you're open to it, I'd like suggest another smallish cleanup in libTablegen, namely doing something about the layering. Basicly what bit me a few times is that there is a `Main.cpp` file. This particular file adds CLI options such as -o, -d, -I. So if you build some out-of-tree tool and happen to link against `all` components because you're lazy, there is a high

Hi all, While working on some features for the AMDGPU backend -- specifically, explicit address components for image intrinsics, which involves generating both (a) a lot of intrinsics with different but somewhat regular parameter types, and (b) the patterns to select instructions for those intrinsics -- I got fed up with a lot of the TableGen bugs and limitations and set out to fix things.

I recently lerned that Mailman adds its footer to MIME multipart messages by putting the original message in the first part of a new multipart/mixed entity and the footer in the second part, with Content-Disposition: inline. It works well in Thunderbird at least, i.e. the footer is visible; the glitch is that the footer shows up as an attachment as well, as does my PGP/MIME signature. Would this

Hi I want to ask a question. (Maybe it is a trivial question.) I found that there is transferSuccessors() in MachineBasicBlcok So that when manipulating MachineBasicBlock, we can use transferSuccessors to update the CFG easily. Why there is not transferPredecessors in MachineBasicBlcok ? Thank you -------------- next part -------------- An HTML attachment was scrubbed... URL:
