Hi how do I extract those components of a list that satisfy a certain requirement? If jj <- list(list(a=1,b=4:7),list(a=5,b=3:6),list(a=10,b=4:5)) I want just the components of jj that have b[1] ==4 which in this case would be the first and third of jj, viz list (jj[[1]],jj[[3]]). How to do this efficiently? My only idea was to loop through jj, and set unwanted components to NULL,

Hello, for one course at our Brno University of Technology, I made a presentation about languages used in LLVM during compilation. I think also other may find it useful, so I am sending it here, so you can add it somewhere on the web if you will would like to. It is not exactly a publication, rather lecture slides. Title: Languages Used in LLVM During Compilation Date: 30th April 2014

Adam, I just fixed this issue a few days ago. A version from the trunk should work for you.

Hello, i need to fold constants, i found that a function ConstantFoldConstantExpression could be used, however I am not able to make it fold anything. Could you please give me some advice, what I am doing wrong? My code looks something like this: //data layout is obtained from clang-generated code for triple arm-none-linux-gnueabi with added v32:32:32 const char* const TARGET_DATA_LAYOUT =

I forgot to mention, that I use LLVM release 2.8, I did not try it with the latest revision, but I expect that I am rather doing something wrong than using non-implemented functions.

I've put together a first cut for a Win32 DLL using the BladeEnc interface. Right now, it's just a drop-in replacement for BladeEnc.dll that ignores all encoding parameters passed to it and uses the info_A vorbis_info struct (same as the encoder_example). It's not particularly useful as of yet, but you can rename it to BladeEnc.dll and use it with any number of rippers out there

Hello everyone, we are planning to implement a stronger alias analysis for backend, because e.g. for VLIW architectures, this is our main performance limitation. I would have 2 questions regarding this. I know that backend processes one function at a time, is it somehow possible to do there a whole program analysis, or could you give me some guidelines? Which alias analysis algorithm

Hello gyus, I am working on a project, where we are trying to create a development environment for new ASIP processor design. Part of this project is a compiler generator, where we would like to generate C compiler from some instruction description. To keep it short, let's say, that in each instruction's semantics is described by some C code. What I would like to do is to compile this

Hello, I would like to ask, whether do the functions code in the compiler-rt library are written in the way that they can be used also for 16-bit architectures, or it was intended for 32-bits only. I looked at the code and it seemed quite portable, but are there any issues I should know when trying it for 16-bit architectures? Thank you Adam

[ please copy me on answers, since I am not subscribed to the list ] Dear all, I am trying to write an R function which uses system.time to determine which of a given list of R expressions executes fastest. To work around the limited resolution of system.time, I want to convert the given expressions into functions which execute the given expressions a fixed number of times. My current attempt

Hello, my name is Torsten Koffler, a Senior Software Engineer at Nero AG (Germany). I am the manager for Windows Quality Online Services (Winqual) issues in our company.

I''ve been playing around with this, but have yet to be successful. I am trying to figure out how to SSH to my Dom0 IP and some static port and then redirect the "xm console <domU>" into the SSH session. Has anyone been successful in doing this? Really the only option I''ve seen is using "screen" on the /dev/pts/[1-x] console device, but that seems overly

Hi, We are now about halfway between the 3.4 and 3.5 releases, and I would like to start preparing for a 3.4.1 release.

April 9 - April 18: Testing Phase April 18: 3.4.1 Release How you can help: - If you have any bug fixes you think should be included to 3.4.1, send me an

Hello, I was searching on the net, but I cannot figure out what instruction selection algorithm is used in LLVM backends in version 2.6. Are there multiple algorithms used, or is it just one? E.g. one for -O0 and different for -O3? Thank you Adam
