Compiling SAFECode poolalloc in cygwin create different libraries compared to linux.
Hi John, That worked for me. I am using llvm 3.2 only and following http://safecode.cs.illinois.edu/docs/Install.html So for I am able to make inside llvm/projects/poolalloc by doing such cosmetic changes. Now, when I tried to make inside llvm/projects/safecode, I see another error. kpawar at KPAWAR-LT ~/SAFECode/LLVM_SRC/llvm/projects/safecode $ /usr/bin/clang -cc1 -triple i38...

[LLVMdev] Clang + SAFECode Release Announcement
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 ca...

[LLVMdev] Clang + SAFECode Release Announcement
Hi, My apologies for the trouble. I've disabled building DynamicTypeChecks for now (r138224) and now it builds cleanly on 32bit for me here. As for SAFECode support for 32bit vs 64bit, I believe 32bit should work just fine although I haven't personally tested this. Let me know if you have any further issues/questions. ~Will On Sun, Aug 21, 2011 at 9:26 AM, Chuck Zhao <czhao at eecg.toronto.edu> wrote: > John, > > The release sour...

[LLVMdev] SAFECode testsuite query
Hello All, I am looking at exploring what benefits SAFECode has to offer over clang S.A and llvm's instrumentation tools like memory sanitizer and address sanitizer. I could come up with the following that are not provided in ASAN/MSAN/Clang S.A -> dangling pointer error and detection -> crashes in system libraries due to security vulnerabilitie...

What options do I give to the patch command to apply it to the source code? Although there's no documentation about contributions to SAFECode as of yet, I'd like to follow the same policy that LLVM uses (notably that the copyright of contributions is passed to the University of Illinois). Is this acceptable to you? We haven't regularly tested SAFECode and Automatic Pool Allocation on 64 bit architectures, so while it may w...

[LLVMdev] SAFECode Source Code Released
Dear LLVMers, We are happy to announce an alpha release of the SAFECode compiler. It is now available for download from the LLVM public Subversion repository. SAFECode uses a set of analysis passes and program transformations to provide strong memory safety guarantees to C/C++ programs. Specifically, the safety guarantees are: o Array bounds checking (prevents...

Tools like ASan and SAFECode *could* use this attribute to determine the size of memory objects created by allocators. This is needed for things like SAFECode's fastcheck optimization (which replaces expensive checks that need to lookup object bounds with a simpler check that has the object bounds passed in as argume...
