[GlobalISel] Narrowing uneven/non-pow-2 types
Hi all, recently when working with GlobalISel we have often encountered cases in the legalizer where instructions could not be narrowed because the narrowing code relies on G_UNMERGE_VALUES and therefore requires the source type to be a multiple of the narrow type. Often times these instructions can be widened without any problem to a fitting type. This has us writing legalization rules like `.widenScalarToNextPow2(0, /*MinS...

RFC: should CVP always narrow the width of lshr?
...the new instructions, or whether the new width is legal for the target. That was implemented in https://reviews.llvm.org/D44102 As Sanjay Patel notes in https://reviews.llvm.org/D47113#1106601, > We overlooked these questions in the specific case of div/rem > (D44102) because we assumed that narrower div/rem are always > better for analysis and codegen <cut> Now, there is a caveat. If <C> is constant, and is a power-of-two, instcombine will transform udiv to lshr, and urem to and. And CVP pass does not narrow the width of those opcodes. And instcombine won't narrow them ei...

Reg Fixed point Speex Narrow Band decoding
Hi Marc, I've downloaded the Speex1.2Beta version. In the code still there are some float variables are used for the Narrow band decoding. In the file "nb_celp.c" .93 is getting multiplied with the GAMMA_SCALING [Line number From - 1341 - 1351] Can please tell me weather the 1.2Beta version has complete narrow band decoding in fixed point?? Thanking you, Regards, T Jyothiprakash Reddy ------...

Extract Variance Components
...39;m still having problems putting the variance components of my model in to a data frame, it is a continuation of this discussion, http://r.789695.n4.nabble.com/ANOVA-problem-td4609062.html, but now focussed on the problem of extracting variance components. I have got my mixed effects model now /narrow$line<-as.factor(narrow$line) rg.lmer <- lapply(split(narrow, narrow$gene),function(x)lmer(value~sex+(1|line:sex)+(1|line),data=x)) str(lme4::VarCorr(rg.lmer[[1]])) (rg.lmer[[1]])/ and want the variance components from each model (one per gene) put in to a data frame, this works for one gene...

Hmisc binconf function value interpretation during narrow confidence intervals
Hello all, I've been using binconf (package Hmisc) at a range of alpha values and noticed that using the 'Wilson' method when alpha is larger (i.e. narrow CI), results in the upper value being smaller than the lower value. The 'exact' and 'asymptotic' methods give results in the realm I'd expect. But the help file suggests: "Following Agresti and Coull, the Wilson interval is to be preferred and so is the default." Sugg...

maximum frame-length for narrow, wide and ultrawide encoding
> What is the maximum frame-length that libspeex will produce for narrow, > wide and ultrawide encoding? In normal operation (no in-band side information, like requests, ack, stereo, ...), the max size for a frame is 62 bytes in narrowband, 106 bytes for wideband and 110 bytes for ultra-wideband.

Mixing SCSI devices on a single i/f
I have an external HP SureStore DLT VS80 with a SCSI LVD 68 pin interface and an external HP SureStore DAT24 with a SCSI Centronics 50 pin Narrow SE interface. The cable for the DAT has a Centronics connector at one end and a 68 Pin Wide to Narrow terminated connector at the other. The cable for the DLT has a LVD/SE 68 pin connector at both ends. I have terminator blocks for both devices. If I connect the devices thus: terminator --&g...

diagnostic functions to assess fitted ols() model: Confidence is too narrow?!
Dear all, When fitting an "ols.model", the confidence interval at 95% doesn't cover the plotted data points because it is very narrow. Does this mean that the model is 'overfitted' or is there a specific amount of serial correlation in the residuals? Which R functions can be used to evaluate (diagnostics) major model assumptions (residuals, independence, variance) when fitting ols models in the Design package? Regards,...

[LLVMdev] Patch: Don't do unprofitable narrowing of loads.
Our backend only does 32 bit loads. I noticed some loads were narrowed to 8 bits and then had to be reverted back to 32 bit loads. This patch prevents the initial lowering. I've only tested this on my backend. Can someone review and apply this or should I submit a bug? Index: CodeGen/SelectionDAG/TargetLowering.cpp =========================================...

configuring speex for narrow band
Hello, I am trying to use speex for speech encoding on my ARM based device. I am facing issues with quality of voice with the narrow band configuration (8k sampling rate). With complexity set to 3 and VBR enabled, I am getting high bitrate output. As an example, My input is 8K stereo and I am passing the encoder with 160 samples at a time as per the manual and samples. When there is a speech I get between 40 to 92 byte...

Video codec for narrow bandwidth streaming
hi, i am a university student and completely new for the video codec technology. we have decided to develop a video codec that is specially focus for narrow bandwidth video streaming (provide video streaming experience for GPRS, etc). so i want to have some idea about how a video codec is related with streaming application...? have there any codec developed for these type of requirement, by your organization or any other developer...? also i want t...

Ajax.autocompleter does not narrow down choices
Hello, I was wondering how to get the Ajax.Autocompleter to behave more like Autocompleter.Local where it narrows the drop down as you type. The local autocompleter seems to exhibit this behavior naturally. Am I missing an argument somewhere?

Confidence intervals and polynomial fits
...24 28.6509494 These tables show the problem: the 95% confidence limits for the quartic term are every bit as wide as the limits for the other terms. Since the quartic term coefficient gets multiplied by the fourth power of x, this means that the width of the confidence band starts out nice and narrow (when x is close to zero, where the width of the confidence band is pretty much just determined by the confidence limits on the intercept) but balloons out to be tremendously wide for larger values of x. The width of it looks quite unreasonable to me, given that my fit is constrained by 300,000 da...

Initial Boot from 6.3 minimal halts with strange video display
...up to the point that the kernel is selected (whether by hand or automatically). I can edit the kernel command line and otherwise use the pre-boot selector facility. After that point the monitor, a BenQ 17" LCD, immediate goes into what I can only describe as a psychedelic snow field with two narrow black bands surrounding a broader white band displayed at the top of the screen and a single narrower black band at the bottom. I have tried booting into RL3 by appending a 3 to the end of the kernel command but this has not apparent effect on the outcome. Any suggestions on how to proceed? --...
