[LLVMdev] DataFlowSanitizer only for Linux
Afternoon,
I had an issue with trying to link a program with the DataFlowSanitizer
functionality, this is from the libFuzzer project, and I was seeing:
clang++ -fsanitize=address -fsanitize-coverage=edge test_fuzzer.cc Fuzzer*.o
Undefined symbols for architecture x86_64:
"_dfsan_create_label", referenced from:

[LLVMdev] DataFlowSanitizer only for Linux
FWIW see also http://lists.cs.uiuc.edu/pipermail/cfe-dev/2015-June/043301.html
As far as I understand DFSan functionality isn't required for
libFuzzer to work, so it should be safe to disable DFSan support on
Mac.

[LLVMdev] DataFlowSanitizer only for Linux
Kostya,
I took a quick stab at patching libFuzzer for Apple, but so far I'm
thinking something else is incorrect. Patch is attached but when I went to
reproduce the examples, the toy example went fine, but with PCRE and
Heartbleed I noticed the coverage statistics were pretty poor, and didn't
find anything. Admittedly I moved onto Heartbleed pretty quickly so PCRE
probably isn't the

LibFuzzer and platforms availability
r247321 refactors the code so that it should build on Mac.
I haven't actually tested it on Mac -- so please help me and send follow up
patches if needed.
check-fuzzer will still fail because some of the libFuzzer tests require
dfsan.
I'd use some help from someone with a Mac to modify
lib/Fuzzer/test/CMakeLists.txt so that it does not run dfsan-dependent
tests on Mac.
Thanks,

LibFuzzer and platforms availability
Hi there.
I’m trying to use LibFuzzer on OSX and face some issues:
I checked out LibFuzzer documentation[1] and managed to proceed until the final step of the first example.
Now I see linker errors related to dfsan, dfsan’s documentation[2] states explicitly “DataFlowSanitizer is a work in progress, currently under development for x86_64 Linux.”.
Does it mean that LibFuzzer available only on

dovecot process dies
Hi to all.
I upgraded my dovecot from rc5 to rc6. Prior to upgrading, it was
working seamlessly. But now I couldn't start dovecot.
Here's what the log says:

OCaml bindings
Hi All,
I’m being a complete newbie on this one but how do I generate the OCaml bindings? I saw an old google post using “configure —enable-bindings=ocaml” but we don’t use configure anymore (I’m building 3.9.1) and if I just do a regular build (optimized) then I don’t see any bindings in my build directory….
Any ideas?

Back tracing Variables
Hi Juan:
I haven't looked at SlotTracker, but have been
using MemoryDependenceWrapperPass to do something similar.

Back tracing Variables
Good Morning - Happy Holidays everyone!
I had a question about the best way to do back tracing of variables via the IR. So for example, if I have the following simple IR:
define i32 @squak(i32 %num) #0 {
%1 = alloca i32, align 4
store i32 %num, i32* %1, align 4
%2 = load i32, i32* %1, align 4
%3 = icmp sgt i32 %2, 10
I’m grabbing the predicate of “icmp”, which in this case is a simple

see what is wrong. The values never get entered in the database. Here are
the files: I have asterisk running as the user asterisk also.
