Hi the list: I can not create R process from Java application with my linux box, the process never was created, or just terminated immediately after I called Runtime.getRuntime().exec(...) The command lines I have tried are(the paths are all correct): "/bin/sh /usr/bin/R" "/bin/sh -c /usr/bin/R" "/usr/lib/R/bin/exec/R"(also set R_HOME=/usr/lib/R) I

Hi all, OpenJDK8 jdk8u-dev[1] is just able to work after compiled with LLVM 3.9.1 for X86: $ ./build/linux-x86_64-normal-server-slowdebug/images/j2sdk-image/bin/java -version openjdk version "1.8.0-internal-debug" OpenJDK Runtime Environment (build 1.8.0-internal-debug-xiangzhai_2018_09_09_21_08-b00) OpenJDK 64-Bit Server VM (build 25.71-b00-debug, mixed mode) $ strings

I need to write the output of a R plot to a Java OutputStream. It looks like R insists on sending it's output to a file. Is there anyway to get bytes directly from the output of a plot so I can write it with Java? Writing it to a file is too slow. Is there a parameter in the graphics device function png(..) that directs output to a variable in memory? x <- plot(.) would make sense. --

As far as I have been able to figure out, dovecot auth always works over a Unix domain socket. I believe it is not currently possible to operate dovecot auth over an Internet domain (TCP) socket. Am I correct? I want to call dovecot's exported authentication from a Java application. Java doesn't natively know how to talk to a Unix domain socket, so there are inconveniences. There

hi on my device i can sample only at 32khz and want to use speex at 16khz so i need to down-convert the input signal by factor of 2. does anyone provide me a reference to some code that does that? are there any trick to do that? i tried to add to subsequent sample but the result was very bad. what are the requrment from a decimation filter for audio? thanks, nir -------------- next part

Hi Dimitry, Thanks for your kind response! Thanks for the commit message of Jung's patch, I found that the bug had been fixed in OpenJDK 12 by Zhengyu https://bugs.openjdk.java.net/browse/JDK-8205965 But only backported to 11. So Jung could backport it for OpenJDK 8, thanks a lot! But I argue that the root cause might be in the compiler side, why clang-3.9.1, gcc-6.4.1 couldn't

that would be an escaping global, and as far as I know is handled separately in GlobalsAA (AnalyzeUsesOfPointer checks if a global is used as operand to a function) On December 4, 2015 11:47:20 PM GMT+05:30, James Molloy <james at jamesmolloy.co.uk> wrote: >It is if one of the operands is or can alias a global ? >On Fri, 4 Dec 2015 at 18:16, Vaivaswatha Nagaraj <vn at

Hi James, Thanks for the help. From the log, I could infer that SLP vectorizer is not preserving alias analysis, preventing GVN from getting the info. Although the first function to get compiled has GlobalsAA available during GVN, rest of them do not as SLP vectorizer run on that function invalidates GlobalsAA which is a module pass. Is there a way to force re-computation of a particular

writing into operands is not the same as writing to globals right? I added printf in the same category since we were discussing writing to globals.

Hi Mehdi, Thank you for the response. I'm actually on an LTO setup and was referring to PassManagerBuilder::addLTOOptimizationPasses. Here, GlobalsAA is scheduled to run well ahead of SLPVectorizer. However since GlobalsAA is a module pass, it runs once and a bunch of passes, including SLPVectorizer is run for each function. When one of them invalidates the analysis, rest of the functions do

Hi James, Thank you for the response. I understand the concern about malloc/free hooks. Could we detect that a program has setup malloc hooks (assuming we're in a whole program compilation) and make assumptions (such as onlyAccessesArgMem()) when the program hasn't setup malloc hooks? Using a command line flag could be one option too. I'm currently working on a program where having

Hello, I think this new list is a good idea, at least there is a place on which this mail is on-topic. Altough I do not know if anyobody is on this list yet. There is a new Java implementation of the Ogg library. The link is http://netmind.hu/ogg This is a high level implementation, meant to be as easy as possible, while preserving all ogg's features. It lacks real-world tests and can be

Thank you both for the inputs. I've created a patch for the same, please review: http://reviews.llvm.org/D15185 >You can specifically insert it into the pass pipeline, but in this case, we should just fix SLP to preserve the analysis. @Hal, I tried doing this but it didn't seem to work. I added the GlobalsAA pass right before GVN but it didn't seem to help. In retrospect, looking
