I get a segmentation fault when starting the IceS encoder on a Linux-based QNAP NAS. I'm trying to set up IceS to stream an ALSA input to Icecast. Icecast works well and confirms when I stream using other things to it. However IceS hits a segmentation fault immediately after starting the encoder. The IceS log is: [~] # sudo ices /etc/ices.xml [2020-05-11 19:24:34] INFO ices-core/main IceS

I am trying to dedicate a number of PCI ports to DomU and no success! The PCI devices I am trying to dedicate are QLogic 23xx cards! I am using SUSE 10.1 with latest xen-unstable!

Hi Justin, I believe the PTX section in the link below need some love, updating "lib/Target/PTX" to "lib/Target/NVPTX" for example. Would you like to take a look? http://llvm.org/docs/CodeGenerator.html#the-ptx-backend Regards, chenwj -- Wei-Ren Chen (陳韋任) Computer Systems Lab, Institute of Information Science, Academia Sinica, Taiwan (R.O.C.)

Hi all, I think it's Gentoo's bug, but I want to know if anyone has the same issue here. I am compiling LLVM trunk on Gentoo (gcc 4.5.2), and I get error message below, --- make[4]: Entering directory `/nfs_home/chenwj/llvm-3.1/svn/build/tools/clang/lib/Frontend' llvm[4]: Compiling InitHeaderSearch.cpp for Release+Asserts build

How about sending a patch which remove those obsolete code, and let others give comment? Cheers, chenwj -- Wei-Ren Chen (陳韋任) Computer Systems Lab,

I can only guess llvm-prof does not recognize the profiling data. Regards, chenwj -- Wei-Ren Chen (陳韋任) Computer Systems Lab, Institute of Information Science, Academia

Hi Pawel, PTX already be replaced with NVPTX. However, PTX subdirectory still sit in lib/Target in 3.2 release. Do you think update the release tarball is a good idea? Also could you remove it from the trunk? Thanks. Regards, chenwj -- Wei-Ren Chen (陳韋任) Computer Systems Lab, Institute of Information Science, Academia Sinica, Taiwan (R.O.C.)

Hi all, While building/testing LLVM/Clang on ARM, I often have problems that are undocumented on the website. I would like to contribute my experience if possible so that others can benefit from it. If this is a good idea, I am wondering on what page I should write it down, [1] or [2]? Regards, chenwj [1] http://llvm.org/docs/GettingStarted.html [2] http://llvm.org/docs/FAQ.html -- Wei-Ren

In other words, this test case guarantee that pr1028 will not back again. If so, it will fail.

Hello, Thank you very much for the pointers. I am are able to create new MDNodes, filled with some constants, and attach them to llvm instructions. However, the metadata map is not getting updated as expected. For example, instead of the expected new entry !n = metadata !{some values} we are getting !n = metadata !{null} Do you know what might be wrong? Do we need to enter the MDNodes into the

Hello all, I caught a problem related to pthread library. I built llvm and llvm-gcc then compiling a multithreaded benchmark written in POSIX thread library. The command "llvm-gcc -o bench bench.c -lpthread" ran well while "llvm-gcc -c bench; llvm-ld -o bench bench.o -lpthread" crashed. It told that "llvm-ld: error: Cannot find library 'pthread'". I could

Hi! I was trying to run an already build LLVM-pass ( the Hello world ) on Visual Studio. I could locate the The Hello world pass sources in llvm/lib/Transform/Hello/*.But when I compiled llvm using the command "cmake -G "Visual Studio 10" ..\llvm" , I couldn't find the LLVMHello.so file in "build_directory/Debug/lib/LLVMHello.so" neither in

Turns out I was using `opt -profile-loader` instead of `opt -path-profile-loader`. Switching to the path profile loader fixed the problem.
