vetor autoregressions and BVARs
I have not been able to find any programs for running vector autoregressions with R. I am interested in running Bayesian VARs and also running VARs that run all combinations of variables in the vector. Is anyone currently developing this? -Nirav Mehta

Exporting objects plotted with plot3d() - rgl package
Dear all, Can anybody tell me how to export a 3d figure made with the plot3d function? I'm careless about whether it's still interactive or not in another format, as long I can get it out of R.

aggregating irregular time series
Hi, I have a couple of aggregation operations that I don't know how to accomplish. Let me give an example. I have the following irregular time series time x 10:00:00.021 20 10:00:00.224 20 10:00:01.002 19 10:00:02:948 20 1) For each entry time, I'd like to get sum of x for the next 2 seconds

aggregating values at discreet irregular time intervals into hourly values
Hello R users, I'm a newby to R (and programming software at large) and I would need some help to sum up event data at discreet time and irregular time interval into a hourly frequency. Here is an example of my time series frame (irregular time-serie object - irts in the tseries package): time value 2008-12-19 19:11:03 GMT 1 2008-12-19 19:12:00 GMT 0 2008-12-19

Blocking and compression.
I did some research on patent claims on range and arithmetic coding. The original range code pdf presented in the UK by an ibm employee at the time asserts no patent claims what so ever. If there are patents I cant find em. I have the original paper in PDF if anyone cares to see it. Its a good candidate for encoding because browsing a few of the implememntations avaialable on line, I can roll my

Optimizing diamond pattern in DAGCombine
Explicitly re-adding a node to be processed doesn't work, because the processing order is canonical. 2017-05-22 11:39 GMT-07:00 Nirav Davé <niravd at google.com>: > You can always explicitly add D to the worklist when you make the > transformation with AddToWorklist.

Optimizing diamond pattern in DAGCombine
The root problem is that, when A gets modified, D doesn't get added back to the worklist. I could match the pattern on A, but the problem remains: when D gets modified, A do not get added back tot he worklist. I also considered ding several round of DAGCombine, but it is very easy to run into infinite loops, even with a fair amount of sanity checks. 2017-05-22 7:30 GMT-07:00 Nirav Davé

x86: How to Force 2-byte `jmp` instruction in lowering
Hmm. Odd. I just rebuilt from scratch and it seems to work with the test/CodeGen/X86/xray-attribute-instrumentation.ll test case outputing straight to obj: llc -filetype=obj -o ~/a.o -mtriple=x86_64-apple-macosx < test/CodeGen/X86/xray-attribute-instrumentation.ll What test case are you using? In any case, the issue appears to be that llvm doesn't realize that the target address is

Heap Exhaustion during 'DAGCombiner::Run'
We discovered what is happening. SDAGCombiner essentially looks at various combinations of nodes to do with vectors, and when it can, it creates a vector shuffle. The problem is, that our vector shuffle lowering builds new trees with vector element, or vector sub-vector insert sequences. The generic DAGCombiner, reconstructs these into a new shuffle, and so the loop continues - we reduce it,

Heap Exhaustion during 'DAGCombiner::Run'
Hi LLVM-Devs, I am in the process of updating our out-of-tree implementation from v5.0 to v6.0 RC3, and while it builds and mostly runs, I am having trouble with a small number of tests where the 'WorklistMap' in 'DAGCombiner::Run' never becomes empty. This is resulting in a runaway state of continuous heap allocation until the process exhausts all system memory. But I can't

Heap Exhaustion during 'DAGCombiner::Run'
Martin: I suspect this is an issue with post-DAG legalization store merging in the DAGCombiner. If you have a custom lowered type the DAGCombiner may end up merging a set of stores and immediately splitting them up in legalization. You should be able to disable this pass universally by overriding mergeStoresAfterLegalization() or conditionally for cases that shouldn't match with

rL296252 Made large integer operation codegen significantly worse.
I see we're missing an isel pattern for add producing carry and doing a memory RMW.

Martin: It sounds like you are doing is more akin to shuffle selection than fusion and therefore it's a better fit for instruction selection than DAGCombining.
