similar to: [LLVMdev] Will LLVM be suitable for developing valgrind like tools

Thanks All In fact, to answer Pete, I was trying to do as much as possible like valgrind including as much as possible, which includes all tools. M very elated to know about ASan, given the fact that LLVM is Compile time whereas valgrind is Dynamic, need to rethink, Can you guys check this. build clang 3.2 but I got this linker error. Let me also examine closely clang++ -W -Wall

> Will LLVM be suitable for developing valgrind like tools It is already used by several such tools, eg ASAN, klee. Ciao, Duncan.

Did you checkout compiler-rt? This page has detailed info on building asan: http://code.google.com/p/address-sanitizer/wiki/HowToBuild?tm=4 --kcc On Mon, Jan 7, 2013 at 9:38 PM, Devchandra L Meetei <dlmeetei at gmail.com>wrote: > Thanks All > In fact, to answer Pete, I was trying to do as much as possible like > valgrind including as much as possible, which includes all tools.

Turns out compiler-rt was missing as pointed out by Kostya. Any clue why line number is not printed, It got compiled with -g -O1 along with flags specified in the link I got following lines on RHEL 6.3 clang 3.2 ==10474== ERROR: AddressSanitizer: heap-use-after-free on address 0x7fb3eb2c6b90 at pc 0x415394 bp 0x7fff49175eb0 sp 0x7fff49175ea8 READ of size 4 at 0x7fb3eb2c6b90 thread T0 #0

Hi All Though, I have used clang which is great. I am dumb in LLVM design. Will somebody be kind enough to answer Will LLVM be suitable for developing valgrind like tools?

In X86CodeGen.cpp, the following code appears in the handler used for CALL64pcrel32 instructions: // Assume undefined functions may be outside the Small codespace. bool NeedStub = (Is64BitMode && (TM.getCodeModel() == CodeModel::Large || TM.getSubtarget<X86Subtarget>().isTargetDarwin())) || Opcode == X86::TAILJMPd;

Is there some description module that support for pipeline usage exposing character ? Some DSP has clustered architecture , Is LLVM fitted for the clustered-architecture ?

As an update to the nouveau development community, the downstream fork of Valgrind with a mmap tracing tool ("mmt") we maintain has been rebased against the latest upstream release of Valgrind, v3.16.1 Code branch: https://github.com/envytools/valgrind/tree/mmt-3.16.1 Features of upstream Valgrind 3.16.x: https://www.valgrind.org/docs/manual/dist.news.html In selected highlights, the

Dear all, I'm trying to debug my R package with valgrind, but I cannot get past the point where I load make the data, as valgrind crashes when trying to extract a single time series object of a multivariate mts object. I'm using R 2.15.0 with platform x86_64-redhat-linux-gnu (64-bit). The valgrind.R contains code data(Seatbelts) y<-Seatbelts[,"VanKilled"] And I run

R CMD check --use-valgrind <packagename> used to run valgrind on the tests in the tests directory of the package. But it seems to have stopped. R-2.9.1 doesn't -- at least on my box -- and neither does R-2.10.0 (devel). I am not sure when this stopped. I think 2.8.x did this. The only old R I have around is 2.6.0 and it certainly does. R CMD check --help for 2.9.1 says (among other

Michael, This looks rather like a 'compile-time versus run-time' question to me. If you look at etc/Renviron.in in the R sources you see a number of choices, some of them with configure-time determined values (which I tend to override with values for the Debian package). For 'EDIT' it is ## Default editor EDITOR=${EDITOR-${VISUAL-vi}} giving us two env vars to override eg

When valgrinding plugins, the following sequence can happen: plugin_free -> dlclose -> unloads the plugin and symbol table exit -> valgrind prints failures (the same applies to filters). When valgrind is printing the failures, it looks up the addresses in the symbol table, but that has been unloaded already so all you see are "???", resulting in useless

I had to add several suppressions because Python leaks memory by design, and also increase the max depth of valgrind stack traces because Python stack traces are very deep. Note that to do proper valgrinding of Python itself we would need to specially recompile Python: https://svn.python.org/projects/python/trunk/Misc/README.valgrind --- tests/test-lang-plugins.c | 3 +-

List, Anybody have a script around that will do this? We have to run valgrind and asterisk to help troubleshoot a bug in the tracker. Since we do not know how to reproduce the error, we'd like to run them from an init.d script (simalar to safe_asterisk), email on crash, and restart asterisk. Ideas? Thanks, PB

Hi, I am trying to debug a package which I helped to develop since we were notified by CRAN that our package randomly fails to run its examples. Hence, I reinstalled R with "with-valgrind-instrumentation=2" and installed our package with MAKEFLAGS="CFLAGS='-O0 -g3' CXXFLAGS='-O0 -g3'" R CMD INSTALL --build hsmm Then, I ran the examples of our package with R

NUT developers, just thought I'd share some notes and ideas on using valgrind against the NUT USB drivers on Linux. Stepping back a bit, I wanted to make sure that the tripplite_usb driver* wasn't using any uninitialized memory, or leaking memory over time. valgrind (specifically, the memcheck tool) runs the code in a special dynamic translator that checks every memory access to see if
