Default-constructibility is overrated—Arthur O’Dwyer

Default-constructibility is overrated

by Arthur O’Dwyer

From the article:

The Ranges Technical Specification includes very many concept definitions (based on the Concepts TS), including for example Integral and Predicate. It also provides a concept named Regular which implements a variation on the “Regular” concept described by Alexander Stepanov in his paper '’Fundamentals of Generic Programming’’ (1998)...

Looking for the bug.

Quick Update on C++ Compiler Bug Hunt

by No Bugs" Hare

From the article:

Some time ago, I wrote a post about kscope – mini-project on finding and reporting bugs in modern C++ compilers. The point was that there is a way to use C++ facilities to make C++ code self-mutating (more strictly – pseudo-randomized using externally supplied ITHARE_KSCOPE_SEED macro), which allows finding certain classes of bugs during randomized testing. In the previous post, I wrote about 12 bugs reported, with 3 of them already fixed. I have to admit that since that point, I didn’t have as much time as I’d like to spend on kscope; still, 3 more bugs were reported (2 of them being codegen bugs) – and quite a few were fixed (fortunately, bugfixing is one thing which doesn’t require my participation <wink />)...

From the article:

Finally, a blog post on [[trivial_abi]]!

This is a brand-new feature in Clang trunk, new as of about February 2018. It is a vendor extension to the C++ language — it is not standard C++, it isn’t supported by GCC trunk, and there is no active WG21 proposal to add it to the standard C++ language, as far as I know...

March 2018 ISO C++ Meeting Trip Report (SG1: Concurrency and Parallelism)—Thomas Rodgers

The future is still getting closer.

March 2018 ISO C++ Meeting Trip Report (SG1: Concurrency and Parallelism)

by Thomas Rodgers

From the article:

This year’s Winter ISO C++ Standard Committee meeting was held in March in Jacksonville, Florida. A number of larger features, for which there is substantial interest but which are also difficult to get right, were discussed:

  • Concepts, along with Concept types from the Ranges TS; see P0898 and n4685
  • Modules; see n4689
  • Coroutines; see n4723
  • Networking; see n4711
  • Executors; see p0443

span lite: single-file header-only version of a C++20-like span for C++98, C++11…—Martin Moene

The view for any range.

span lite: single-file header-only version of a C++20-like span for C++98, C++11 and later

by Martin Moene

From the article:

span lite is a single-file header-only library to provide a bounds-safe view for sequences of objects. The library provides a C++20-like span for use with C++98 and later. If available, std::span is used, unless configured otherwise...

Much to expect from this years set of Keynote speakers at Meeting C++ 2018

Keynotes at Meeting C++ 2018

by Jens Weller

From the article:

Two of them are well known for a long time in the C++ community as speakers and book authors, while Lisa can be seen as a newcomer. All three of them still have some time to think about what they'd like to talk about, I might give you more insights into the keynotes later this year.
