Hello! A proposal (quaintly identified as P0190R0) for a new memory_order_consume definition may be found here: http://www2.rdrop.com/users/paulmck/submission/consume.2016.02.10b.pdf As requested at the October C++ Standards Committee meeting, this is a follow-on to P0098R1 that picks one alternative and describes it in detail. This approach focuses on existing practice, with the goal of

According to the IMAP spec if I do a search for "TO isocpp.org" it should find all the messages whose To: field contains the string "isocpp.org", but dovecot is returning me an empty list. However, a search for "TO tm at isocpp.org" produces a long list of messages. This behavior is present if I *even load* the lucene fts plugin....

Actually, undefined behavior is essential for serious projects, but not for the reasons mentioned. If the language has no undefined behavior, then from the compiler's view, there is no such thing as a bad program. All

...required. People do try to use R internals in C++, but C++98 compilers are not required to support these types (and there are currently no C++11 compilers). But since the summer we have g++ and clang with working C++11 implementations: iii) g++ implements C++11: http://isocpp.org/blog/2013/05/gcc-4.8.1-released-c11-feature-complete iv) llvm/clang++ implements C++11: http://isocpp.org/blog/2013/06/llvm-3.3-is-released I would suggest to change the wording prior to the release of R 3.1.0 next year as it is likely that even Microsoft will by then have a fully-...

Hi everyone, The OpenMP standards committee has begun work to formalize their memory model, and define its relationship to the C/C++ memory models. A questionnaire has been put together (pasted below), and I'd like everyone's help in composing detailed answers to inform their decision-making process. While our OpenMP support is still in active development, many of these questions apply

Hi, trying to develop this idea of splitting c++ classes into real interface and implementation and to make a std isocpp proposal out of it. Need some help and info to make the proposal cover as many details as possible. The idea is to split the class declaration into a part that will stay in the header and will contain only the public members. (let's ignore protected for the moment). The c++ part will contain t...
