Hello llvmdev, I would like to propose and discuss yet another dynamic tool, which we call MemorySanitizer (msan). The main goal of the tool is to detect uses of uninitialized memory (the major feature of Valgrind/Memcheck not covered by AddressSanitizer). It will also find use-after-destruction-but-before-free in C++. The algorithm of the tool is similar to that of Memcheck (

I've just sent a code review request to llvm-commits. --kcc On Mon, Jun 18, 2012 at 2:39 PM, Kostya Serebryany <kcc at google.com> wrote: > Hello llvmdev, > > I would like to propose and discuss yet another dynamic tool, which we > call MemorySanitizer (msan). > The main goal of the tool is to detect uses of uninitialized memory (the > major feature of

Hi again, MemorySanitizer (msan) is now mature enough to bootstrap LLVM and run it w/o any additional tools. Msan has already found one bug in LLVM itself: http://llvm.org/bugs/show_bug.cgi?id=13929 Would anyone be willing to do a codereview (it was sent to llvm-commits: http://permalink.gmane.org/gmane.comp.compilers.llvm.cvs/123253) Thanks, --kcc On Tue, Jun 19, 2012 at 11:34 AM, Kostya

Dear All, We have a new release of Clang with SAFECode technology for detecting memory safety errors. Memory safety checking (SAFECode for short) can be turned on with a single command line switch to clang/clang++. The SAFECode techniques do not change the behavior of the clang/clang++ compilers in any way when the switch is turned off, so this can be used as a drop-in replacement for

There's plenty of code out there that does wide loads like this directly (without them being created by

Hi, I am new to using wine. I wanted to run our office's tax preparation program (Drake). Using wine, I installed a workstation version of Drake by running a program off the server, as has been done on the windoze machines here. I can get the program to start (the console shows "fixme:wininet: InternetGetConnectedState always returning LAN connection", but I understand that this is
