You mean 'cachegrind'? http://valgrind.org/info/tools.html#cachegrind I don't know any public tool better than this (but someone please tell me if I am misinformed). - Daniel On Tue, Sep 1, 2009 at 2:42 PM, Juan Carlos Martinez Santos<juanc.martinez.santos at gmail.com> wrote: > Hello everybody, > > I am looking for a tool (in Linux or Windows) that allow me to get

Hi Guys, I am an absolute newbie to the compiler community. I am experimenting a little bit with llvm. I have a few small questions, i would be really great if someone could help me. 1. Can i find out (is there something already built), if the previous instruction / or some instruction was a cache miss. Basically i want to detect cache misses and instructions that are causing this 2. Can i find

Hi i am using pap2 phone adaptors as clients to connect to asterisk server i am able to make calls but i cannot access voice mail using phone or start recording while call is in progress and when i place a call to local sip extension there is a long pause ( 15 sec ) before the call gets dialled i assume that the problem would be due to the dial plan in PAP2 if so please help me changing it

HI I have two sip accounts from two different ITSP's both configured on asterisk server. how can i know if these accounts have been successfully registered ? i generally look at the /var/log/asterisk/full suggest me if there are better way of doing this thanks Giridhar Bandi -------------- next part -------------- An HTML attachment was scrubbed...

The reasons I have posted these questions are: 1) To find out if Speex can take advantage of SIMD extensions. 2) To maybe learn from someone with previous experience in optimizing Speex for moderns x86 architectures before I set off trying all kinds of things on my own.

Hi all, I'm setting up an IVR using Asterisk. Is there a way to have two streams played to the caller at the same time: for instance, one constant flow of background music, and the IVR contents at the same time? I've looked for solutions using (E)AGI and other things but nothing seems to work. Googling around and reading the list has not been helpful either... Thanks for your help,

I am rebasing Fedora rawhide oprofile package to oprofile-0.9.7. The xenoprof patches on http://xenoprof.sourceforge.net/#download look a bit dated. The newest version is for oprofile-0.9.5. I massaged the patch oprofile-0.9.5-xen.patch to apply to oprofile-.0.9.7. Attached is that updated patch. Does this look reasonable? Is there a desire to get this into upstream oprofile? Or should the

These patches address issues in the kernel part of xenoprof: * Ill-advised use of on_each_cpu() can lead to sleep with interrupts disabled. * Race conditions in active_domains code. * Cleanup of active_domains code.

I have a question about the performance of the implementation of the stack protector in LLVM. Consider the following C program: ===== void canary() { char buf[20]; buf[0]++; } int main() { int i; for (i = 0; i < 1000000000; ++i) canary(); return 0; } ===== This should definately run slower when stack protection is enabled, right? I have measured the runtime of

I've been trying to get oprofile results for jitted code without success. I built an 3.5.0 llvm with oprofile enabled, and tested it with lli on a small test case. I built the latest oprofile from the git repository. Debugging I can see that lli is registering the listener and making the oprofile calls to the libopagent api to specify the names and address ranges of jit'd routines, and

Keir, The following 3 patches allow HVM (SVM and VT) guests to be passively profiled using the very latest patches from Renato. These patches apply to 11470. Renato''s patches: http://xenoprof/sourceforge.net oprofile-0.9.1-xen-r2.patch And also a patch not posted FAIK (oprofile-0.9.1-fix-hvm-addr-overlap.patch) which is in the attached tar.bz2 file. hvm_xenoprofile_1.patch - The first

Mi Maurice, A follow up to Andy's comments: MCJIT can find line numbers for ELF files, at least in limited circumstances. I know because I broke the regression test for it while doing some cleanup recently. ;) Looking at lib/ExecutionEngine/OProfileJIT/OProfileJITEventListener.cpp, I see the line: // TODO: support line number info (similar to IntelJITEventListener.cpp) >From a glance at

Hi Renato, This patch is to add Xenoprof passive domain support in SMP environment. Basically: - It allocates per vcpu buffers for passive domain and maps them into primary domain''s space. - When primary domain gets sampled and triggers virq, its kernel module will handle passive domain'' samples besides its owns. There is potential buffer overflow if passive is very busy while
