Any luck reproducing the problem with opus_demo or opus-tools?

Oh, if the output is stuck at -32768, then it's likely some NaNs crept in. The first thing to check is whether the problem is on the

Hi Stepan, I would need more information to be able to investigate further. It's legal for the decoder to output -32768, so it would be good if you could explain how this is unexpected. Ideally an audio file with details on how to reproduce the problem would help. Optionally, if you could bisect the git repo to see where the problem started.

Hi all. The question about 'load' instruction. When we promote v2i5 = load <addr> ; <MemoryVT = v2i5> to v2i64 = load <addr> ;<MemoryVT = v2i5> should we insert vector shuffling that moves second v2i5 item to the second v2i64 item? Or it is still depends from target? Thanks. -Stepan.

Hi all. Is there any way to look how my changes affected on compile and exec time, except looking at global test-suite compile and exec time? In another words is there any way to detect regression/improvement for particular tests? Thanks! -Stepan.

I hope you don?t mind us using this mailing list for a small advertisement, but we think it is most relevant for this group: We'd like to invite you to RIOT 2020 - the 5rd workshop on R Implementation, Optimization and Tooling [1]. It will take place co-located with, and during, useR! 2020 in St. Louis on July 8th. RIOT is an excellent venue for deep technical discussions about R

I just want to update test/Transforms/LowerSwitch/feature.ll that already uses grep. It uses grep + count, probably due to shorter construction. -Stepan.

Hi all, I propose simple improvement for MergeFunctions pass, that reduced its complexity from O(N^2) to O(log(N)), where N is number of functions in module. The idea, is to replace the result of comparison from "bool" to "-1,0,1". In another words: define order relation on functions set. To be sure, that functions could be comparable that way, we have to prove that order

Hi everybody. I found that there are some problems with symbol location in AsmParser. 1. We need to know where symbol was declared. 2. We need to know where symbol was defined first time. There are two ways: 1. Add helper table to the parser with additional symbol info. But it takes additional memory consumption. 2. Add user tag (void*) for MCSymbol object. As I understood MCSymbol can live

Yes. It doesn't works properly. I also read the your discussion in bug 1784: http://llvm.org/bugs/show_bug.cgi?id=1784 I found that know Type and Vector Lagalization and in DAGCombining implicitly assumed that element size of MemoryVT is multiply of 8 bits. Thats the main reason why v2i5 works improperly with load/store. But I can't determine exactly what MemoryVT means... -Stepan.

Well... each case is represented as pair<BB, vector<Range> >. Right? We need "union" for optimal case building. And we need support "difference" if we decided that some ranges or numbers in case will never used (in some optimization passes it happens sometimes). -Stepan 26.04.2012, 15:18, "Duncan Sands" <baldrick at free.fr>: > Hi Stepan, >

Even more - we need to combine our efforts, in order to bring this pass into real live. I'have read your presentation file, and unfortunately read your patch only a little. How exactly you scan functions on 2nd stage? Could you explain the algorithm in

Hi. I just want to know does anyone has the same problem or not. After running "make check-lit" tests are stopped at 61th percent (Linker tests). Each time it stops on different tests. Thanks. -- Regards, Stepan

Stepan, If you interested in only running a subset of the suite, then you can just cd to the associated subdirectory and execute the make command there. Due to the structuring of the makefile it's rather difficult to run an individual test. If you want to setup the structure of the test-suite (say after a fresh checkout/build) I've found that 'make -n' is helpful. It will allow

Probably, I misunderstood MemoryVT purpose? Should it be a type that equal to original vector type (e.g. v2i5). Or it is a type of memory area for this vector (e.g. v2i8) ? -Stepan.

Even though I use aseert np.all(m1 == m2) when working with NumPy, I got accustomed to the "handy shortcut" that I can omit all() with R vectors and matrices. Then I got trapped with the thing I reported. On a second thought,
