Will someone in charge please complete LLVM's page at google-melange.com? Without that LLVM is missing in the list of participants: http://www.google-melange.com/gsoc/accepted_orgs/google/gsoc2013 On Mon, Apr 8, 2013 at 11:11 PM, Anton Korobeynikov <anton at korobeynikov.info> wrote: > Dear All > > I'd like to announce that this year LLVM Compiler Infrastructure >

Currently the replacement of allocation routines is based on creating a new malloc zone and a new CFAllocator (because the allocator replacement is done later than it could be, we must have both). This makes us depend on CoreFoundation to call CFAllocatorSetDefault. Because of some bugs in CF which start firing after CFAllocatorSetDefault, we have to add several hacks to circumvent the effects of

+kledzik at apple.com The dynamic runtime is using dylib interposition (google for "__DATA,__interpose). If I'm understanding correctly (Nick, can you please confirm this?) this allows to interpose the function regardless of the two-level namespace. The support for dynamic runtime in ASan is almost there. But the new interposition method has revealed some issues with the allocator which

Hi, can you please check the problem is fixed by r195125?

Hey guys, My local build is broken after: >r194813 | glider | 2013-11-15 08:13:01 -0500 (Fri, 15 Nov 2013) | 2 lines > >[ASan] Add the configure+make rules for building the ASan runtime for iOS > simulator. Tim Northover was kind enough to track this down to a dependency on the “iphonesimulator” SDK. How should this issue be resolved? I'm currently following the receipe to build

Hi everyone, We've decided to apply for this year's Google Summer of Code. Xiph.org has taken part before, so we hope to get at least one or two, maybe even 3 students. If we get chosen we need project ideas and mentors though. We've already started to collect some ideas that would hopefully be sized for students here: https://wiki.xiph.org/Summer_of_Code_2015 That page also lists

+llvmdev Question to MacOS gurus: is there a way to disable ASLR (address space layout randomization) on Darwin at link time instead of doing setenv("DYLD_NO_PIE", "1", 1); and reexec?

If this is the same test: http://gcc.gnu.org/cgi-bin/cvsweb.cgi/gcc/gcc/testsuite/g++.dg/eh/cond1.C.diff?cvsroot=gcc&r1=NONE&r2=1.1, then it doesn't fail for me on Mac OS 10.8 with ASan (Clang r168632) Have you tried symbolizing the report?

Looks like this happens on x86_64 because the position of __cxa_throw is too far from the allocated branch island (should be <2G). This can be solved by allocating the branch islands somewhere near the text segment (look for kIslandEnd in asan_mac.cc, this is currently 0x7fffffdf0000) or by patching the function with a longer instruction sequence that stores the jump target in a register and

Note that I've set the SA_NODEFER flag for the SEGV handler in the ASan runtime only a couple of days ago. Not sure that could've affected this test though; without that flag the second SEGV would've simply crashed the program. But you can try removing the flag from compiler-rt/trunk/lib/sanitizer_common/sanitizer_posix_libcdep.cc and see if that makes any difference. HTH, Alex On

Dear lazydev, I'm writing an instrumentation pass that depends on AliasAnalysis. My getAnalysisUsage() looks as follows: 2453 void ThreadSanitizer::getAnalysisUsage(AnalysisUsage &AU) const { 2454 AU.addRequired<TargetData>(); 2455 AU.addRequired<AliasAnalysis>(); 2456 } and the pass initialization: 2668 char ThreadSanitizer::ID = 0; 2669

Just want to remind everyone that we plan to stop using mach_override in asanin favor of OSX's native function interposition. So, we probably don't want to spend too much effort fixing mach_override. --kcc On Fri, Nov 30, 2012 at 4:46 AM, Alexander Potapenko <glider at google.com>wrote: > Looks like this happens on x86_64 because the position of __cxa_throw > is too far from

Dear prospective GSoC Students! Please note, that you won't receive any reviews of your proposals from SoC webapp automatically. You **need to explicitly** subscribe for them. Please do it now and respond to requests / comments already made in some of applications.

(see http://code.google.com/p/address-sanitizer/issues/detail?id=23) In order for exceptions to work correctly, it should be possible to unwind through the functions wrapped by ASan RTL (in particular, __cxa_throw()) Because we intentionally build the runtime with -fno-exceptions, we need at least the unwind tables to support _Unwind_Backtrace(). -- Alexander Potapenko Software Engineer Google
