Hello Everyone! Here's what I'm trying to do. I'm working on generating occurrences of precipitation based upon precipitation occurrence for a station during the previous day and two stations that have already been generated by joint probablities and 1st order Markov chains or by the same generation process. This has to be done for each remaining stations for each month. > genmat

I am having trouble adding a node to the selection DAG (e.g. during combine) E.g. node1 -> use1, use2 Now if you add a node2, with node1 -> node2 with node2 number of output values equal node1 number of output values, then combine as well as e.g. promotion pass with replace all of node1's uses with node2, leaving node1 dead. While this is kind of expected, does this mean a) always

The SCEV framework sorts operands of commutative SCEVs by their getSCEVType() value, and then does an ad-hoc sort to group repeated operands, but it does not do a full sort. In some test cases I'm looking at right now, this causes it to miss opportunities to reuse SCEV objects, as in cases like this: ( %i + %r54 + %r59) ( %r54 + %r59 + %i) As a result, passes like LoopStrengthReduce

In short: Shall analysis of a SCEV expression be allowed even though part of the IR that was analyzed to build the SCEV expression has been removed? In more detail with background: About a month ago I landed https://reviews.llvm.org/D87494 where SCEV is used to do additional debug-info salvaging in LSR. The idea was to compute (and store) a SCEV of what llvm.dbg.value intrinsics inside the loop

This turns out to be an SELinux issue. Does anyone know the proper commands to restorecon or otherwise to set the SELinux policy for persistent/volatile database files moved to a different directory?

Running into problems configuring different locations for the volatile and other database directories. Can someone provide a quick sanity check on what I'm doing below? Thank you. Given [database] volatile database directory = /var/cache/dbdir/volatile persistent database directory = /var/cache/dbdir/persistent state database directory = /var/cache/dbdir/state And given, [root

Hi All, I'm new to R and am trying to run a unit root test on the vector "y" (a time series of inflation (i.e. changes in the Consumer Price Index quarter on quarter)). I've run the Augmented-Dickey-Fuller Test below (R's URCA package). It gives me an error that it cannot find the function ur.df unless I comment out the third last line of code (see below). I try to call

Hello, I am using the ur.df function from the {arca} package to run the augmented Dickey-Fuller unit root test on several time series. However; I do not understand the econometric interpretation of the the "phi1" and "phi2" test-statisitc which are output if you choose a "trend" or "drift" model. I looked at the source code for the function but I do not

Hi Preston, I was wondering ... "Bottom" is a bit overloaded as far as terms go. Would SCEVNaN be a better name for this beast?

Hi, I noticed an inconsistency in how ScalarEvolution orders instruction operands. This inconsistency can result in creation of separate (%a * %b) and (%b * %a) SCEVs as demonstrated by the example IR below (attached as gep-phi.ll)- target datalayout = "e-m:e-p:32:32-f64:32:64-f80:32-n8:16:32-S128" define void @foo(i8* nocapture %arr, i32 %n, i32* %A, i32* %B) local_unnamed_addr {

Would it be a SCEVExpr? evaluateAtIteration takes a scev, so apply will take a scev, or a map (loop->scev). You can always build a ScevUnknown from an SSA name and use that in the apply. > At the moment, we calculate at the beginning of each >

Hi all, I'm working with a dataset from 10 treatments, each treatment with 30 subjects, each subject measured 5 times. The plot of the dataset suggests that a 3-parameter logistic could be a reasonable function to describe the data. When I try to fit the model using gnls I got the message 'Step halving factor reduced below minimum in NLS step'. I´m using as the initial values of the
