Hi all, The LLVM benchmarking system produces very noisy results even on quiet machines. One of the sources of inaccuracy is the timing tool we are using. Because it is a user-space tool, the OS can context switch it and we will get an outlier result. Perf stat uses SW_TASK_CLOCK counter in kernel to measure time, therefore more accurate. It also does not get context switched. I've

Okay to push this change?

I attach two wav files of a few seconds duration that fail to play on Windows Media Player 11 using DirectShow Filter bundled in oggcodecs_0.71.0946.exe, after enconding them to the Speex audio format using VBR, as follows: speexenc.exe --vbr <input-wav-file> <output-spx-file> The output of speexenc.exe --version* *is: speexenc (Speex encoder) version speex-1.2beta3 (compiled Dec 11

This isn't exactly a Samba problem, but I am hoping the experts here can help me. I have been trying to get my OpenIndiana system to join a Samba4 domain and I was running into multiple problems. So I decided to test against a true Windows Server (2003) domain, to see if there is something wrong with my client-side setup. Attempting to join the WS2003 AD domain also fails. Snooping the

The issues seems to be this line in the tools Makefile timeit-target: timeit.c $(LD_ENV_OVERRIDES) $(LCC) -o $@ $< $(LDFLAGS) $(CFLAGS) $(TARGET_FLAGS) -O3 It should not add target flags if we are simulating the target on the host.

I downloaded speex-1.2beta3-win32 binaries, and used the speexenc.exe and speexdec to process the file male.wav download from http://speex.org/samples I used both the narrowband and ultra-wideband mode: >speexenc -n --quality 3 male.wav n3.spx Encoding 8000 Hz audio using narrowband mode (mono) >speexdec n3.spx n3.wav Decoding 8000 Hz audio using narrowband mode (mono) Encoded with Speex

Hello everyone, I am working to run the LLVM Nightly Testsuite on embedded arm devices. Not all of these devices can mount NFS to share a common directory tree. To mitigate this I have patched test-suite/RunSafely.sh (attached) to create a temporary directory, run the test remotely, collect the output, and cleanup after itself. The patch breaks compatibility with the current remote device model

I hit the same problems as you did when I tried it a few weeks ago. Haven't bothered with it since. There is a way to run tests without using lnt. You can use the Makefiles directly in your test-suite build directory. For running nightly tests, you can do: make report.html TEST=nightly That will generate a html file with the test results in.

Hi, I'm trying to setup the test-suite and am getting short of running it... Following the steps here: http://llvm.org/docs/lnt/quickstart.html I got as far as getting lnt installed, but when I run the "lnt runtest nt" it fails: compilers.py:81: error: unable to determine compiler version: 'clang++': 'clang version 3.2 ' Seems my string doesn't have a

To whom it corresponds, I have been trying to connect my RHEL4 machine through public key authentication against a windows server 2003 machine running OpenSSH for Windows v3.8.1p1-1. I set up everything: keys, user, etc. Doing sftp -vv user@<wsip> I see that authentication went ok but somehow, connection hangs up. I removed anti-virus and other security software on the ws2003 machine

In running the test-suite (llvm 3.0), in the *.out.time files in the Output folder the following line appears: sh: time: command not found This occurs when the following lines are executed: #RunSafely.sh ( sh -c "$ULIMITCMD $TIMEIT -p sh -c '$COMMAND >$OUTFILE 2>&1 < $INFILE; echo exit \$?'" ) 2>&1 \ | awk -- '\ BEGIN { cpu = 0.0; } /^user/

Hi, I am not sure if this is the right forum. Please direct me to the appropriate place if it isn't so. Please keep in CC as i am not subscribed to this mailing list. I am trying to test riscv llvm tools in QEMU using llvm testsuite. As a trial i am trying only the Single Source C Regression folder. The steps that i took are : ]$ cmake -DCMAKE_C_COMPILER=/opt/riscv-tools/bin/clang

That would seem even better to me, but data would be better. =] That's an interesting idea. However I'm concerned if that will miss some aspects of compiler optimization. For example frequent cache misses would have much smaller

I want to get lnt to use qemu for the execution. In that case, RHOST= is not set. But I change the Arch because I am going to run in cross mode. Then I'm setting RUNUNDER to be a script which runs qemu. In this case it builds timeit-target as a Mips which fails because this is running on x86. ~/mysandbox/bin/lnt runtest nt --sandbox ~/mysandbox --cc /local/llvmpb_a/install/bin/clang

All, I have been trying to get PCI pass through working for sometime and need to know if I have a hardware problem (does my hardware support PCI pass through) or if I am doing something in correct. 1) My BIOS does allow me to enable VT support 2) *cat /proc/cpuinfo* processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Xeon(R) CPU

I've set up a public LNT server to show the result of perf stat. There is a huge improvement compared with timeit tool. http://parkas16.inria.fr:8000/ Patch is updated to pin the process to a single core, the readings are even more accurate. It's hard coded to run everything on core 0, so don't run parallel testing with it for now. The tool now depends on Linux perf and schedtool.
