Hello!
Has anyone else tried valgrind in combination with LLVM/clang as
compiler?
I use valgrind-3.6.0.SVN-Debian on Debian Stable/Testing in 64 bit mode,
with C/C++ code compiled with LLVM/clang 2.9. There are some kinks:
* Line information is missing in valgrind report. That works when

Hi,
I see that there are efforts to make Valgrind works on Android as referred
in https://bugs.kde.org/show_bug.cgi?id=266035 .. Will these patches make
it to the next release of Valgrind?
See
* Line information is missing in valgrind report. That works when
compiling with gcc.
Yes, I noticed that too. I haven't investigated. btw, you should
have a look at https://bugs.kde.org/show_bug.cgi?id=242137,
which is also related to a LLVM+Valgrind issue.

Hello!
Can anyone tell me, is it possible to collect number of fetches and
cache misses for a particular array using Callgrind/Cachegrind?
For example, I have such fragment:
for (j = 0; j length; j++) {
for (i = ip[j]; i = ip[j+1]-1; i++) {

I was trying to use valgrind on one of my applications. The program runs fine
on its own, but valgrind reports a SIGSEGV and exits without running any of my
application, as far as I can tell.
I have been able to reproduce the issue with a simple test. The test does not
even use log4cxx, but
I am on Fedora Core 14, kernel 2.6.35.12-88, g++ 4.5.1, glibc-2.13.1.
int main(const int argc,
const char** argv)
{
return (0);
}
g++ -g -Wall -o Test.o -c Test.cpp ### Note no src/
g++-g Test.o -o test -llog4cxx
It works for me on Fedora 14:
Thanks a bunch for trying it out John.
I have valgrind 3.5.0, and LD_LIBRARY_PATH points to /usr/local/lib, which is
where log4cxx libs are. That's all I can think of in the env. Different from
yours, mine is not 64-bit Fedora. Are your gcc etc. versions the same?
Wonder where I should look?

Unfortunately not possible at the moment.
The ideal thing would be to add a command line option for please
Thanks, John. Since the last message, I removed valgrind-3.5.0 (seems like the
latest available RPM for Fedora-14), built and installed valgrind-3.6.1. Still
no go, same results!

Here's ldd output:
libapr-1.so.0 = /usr/local/lib/libapr-1.so.0 (0x0080e000)
libaprutil-1.so.0 = /usr/local/lib/libaprutil-1.so.0 (0x002c4000)
John,
Had to leave, will post the ldd list in the morning.
I deleted my locally built log4cxx, apt and apt-util from /usr/local/lib, and
reinstalled using yum. Now the ldd list is bigger and more like yours, except
for differences like gcc-4.5.1 versus 4.6, etc.
Thanks for your help!

Good evening, I am trying to use the callgrind profiler to profile my C++
program. I am using Valgrind version 3.6,1 on Linux Centos Version 5.5 on a
Intel 32-bit processor. I keep getting the following error(shown
below) when I try to profile my program.
I already used Linux gprof but
