clang-ppc64be-linux-lnt flakiness
I threw all the sanitizers I had access to on this test and didn't find anything. The merging uses threads so I can't rule out nondeterminism. It's strange that it only happens on ppc64le and only on stage 2, so an actual miscompile wouldn't surprise me either.

Hi Bill, just a heads up but this bot seems to have spuriously failed on a build that only pulled in my commit r272505 which is unrelated. http://lab.llvm.org:8011/builders/clang-ppc64be-linux-lnt/builds/4883 -- Sean Silva -------------- next part -------------- An HTML attachment was scrubbed...

Migration Samba4 and LDAP packages from CENTOS to DEBIAN
Dears, i have Samba4 and LDAP in CENTOS , but i have install this samba4 in DEBIAN How i to search the equivalent package for compilation samba in Debian repository quickly. I used this below packages for compilation samba4 in CENTOS. findutils readline glibc-devel findutils-locate gcc flex compat-readline4 db-devel gcc-c++ make python libacl-devel libblkid-devel gnutls-devel readline-devel

Migration Samba4 and LDAP packages from CENTOS to DEBIAN
Hai Rowland, Can you add in the wiki.. If you are building Samba >= 4.5.0, you will also require libgpgme11-dev python-gpgme python-m2crypto And from debian backports you may need : debhelper dh-autoreconf dh-strip-nondeterminism libfile-stripnondeterminism-perl (At least, i did need them.)

[LLVMdev] LLVM / C--
...kipedia.org/wiki/GLR_parser Advantages When implemented carefully, the GLR algorithm has the same time complexity as the CYK algorithm and Earley algorithm -- O(n3). However, GLR carries two additional important advantages: The time required to run the algorithm is proportional to the degree of nondeterminism in the grammar -- on deterministic grammars the GLR algorithm runs in O(n) time (this is not true of the Earley and CYK algorithms) The GLR algorithm is "on-line" -- that is, it consumes the input tokens in a specific order and performs as much work as possible after consuming each tok...

Seeking suggestions about interfacing of LLVM DataFlowSanitizer library with KLEE in C code.
Dear Developers, I am a Master's student at the ECE department of the University of Florida, USA.​​ For my research project, supervised by Prof. Mark Tehranipoor<http://tehranipoor.ece.ufl.edu/> and Prof. Farimah Farahmandi<http://farimah.ece.ufl.edu/>, I need to use Clang LLVM DataflowSanitizer library in KLEE. However, I have faced some difficulties (explained below) while

[LLVMdev] Integer handling
...itstream with some metadata at the front describing the structure (it uses 4 or 5 bits per structure 'element', so there is a little overhead, but it is very little). The Message is then sent off and the receiving Actor will receive it in some amount of time (the Actor model uses unbounded nondeterminism, yea, try imagining that), when it does receive it then in the event loop it parses it like this (this is more erlangish syntax since I have not finalized my syntax for the receiving loop in my language): receive -> {"Calc", MyDataType newData, PID sender} -> // calculate someth...
