similar to: [LLVMdev] ThreadLocal and constness

I'm probably missing something obvious here, but naively, this makes it kind of awkward to have mutable thread local state... -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20141212/53b577ae/attachment.html>

Hi, LLVM/Clang version: 3.2svn (r156975). I have a bitcode file that I'm trying to load/execute using lli as below but it reports an error about unresolved symbol: > LLVM ERROR: Program used external function '_ZNKSt3__16locale9use_facetERNS0_2idE' which could not be resolved! > lli: /local/mnt/workspace/ashoknn/crd/neo/llvm/proto/llvmsvn/llvm/lib/Support/ThreadLocal.cpp:54:

Resending, any pointers? I demangled the symbol and it turns out to be: std::__1::locale::use_facet(std::__1::locale::id&) const tia, ashok On 5/19/2012 9:41 PM, Ashok Nalkund wrote: > Hi, > LLVM/Clang version: 3.2svn (r156975).

We can't guarantee what storage duration the caller's request for a thread name has; and in fact, if the caller uses plugin_name() for their thread name, then the moment .unload is called, our threadlocal storage is pointing to la-la-land and we get a nice SEGV while trying to print any debug message. So copy the user's string instead. Signed-off-by: Eric Blake

That

The attacker is forced to rely on side channel information such as timing channels in an attempt to discover the length of the inserted NOP sleds. This sounds like an extraordinarily difficult task, but possibly doable. With a

Hi, everyone: I am very sorry to trouble you, but I need your help about my problem about ThreadLocalImpl in llvm of 2.8 version. I have compiled it in Windows xp with mingw, and have compiled skyeye(an open source project about simulator) as it uses llvm. But when I run a testcase ---- arm_hello, it came out segment fault. I used gdb.exe to trace it, it gave the following infomation: $

Greetings LLVM Devs! I am a PhD student in the Secure Systems and Software Lab at UC Irvine. We have been working on adding randomness into code generation to create a diverse population of binaries. This diversity prevents code-reuse attacks such as return-oriented-programming (ROP) by denying the attacker information about the exact code layout. ROP has been used is several high-profile recent

When accepting a connection on a TCP or Unix domain socket we recorded the peer address in both the thread_data struct and thread-local storage. But for no reason because it was never used anywhere. Since we were only allocating a ‘struct sockaddr’ (rather than a ‘struct sockaddr_storage’) it's likely that some peer addresses would have been truncated. Remove all this code, it had no

If the plugin .pread method did not fill the buffer with data then the contents of the heap could be leaked back to the client. To avoid this create a thread-local data buffer which is initialized to zero and expanded (with zeroes) as required. This buffer is shared between pread and pwrite which makes the code a little bit simpler. Also this may improve locality by reusing the same memory for
