Talk from Dublin C++ User Group 11.06.2018.

Variadic templates and fold-expressions

by Denis Sukhonin

About the session:

Abstract: It all started with a single printf causing undefined behavior due to mismatch of the format string and arguments. To solve similar problems in a type-safe manner C++ introduced variadic template parameters and fold-expressions. Denis covers the basics and shows how a type-safe printf function can be implemented.

PVS-Studio 6.24 released

By Andrey Karpov | Jun 14, 2018 06:01 AM | Tags: tools static code analyzer secdevops pvs-studio devops cwe arm

A new release of the PVS-Studio static code analyzer became available to download. This tool is designed to detect errors and potential vulnerabilities in the source code of programs, written in C, C++, and C#.

PVS-Studio 6.24 released

by Andrey Karpov

From the article:

Support for Texas Instruments Code Composer Studio, ARM compiler was added under Windows\Linux. 8 new diagnostics were introduced to detect errors in C and C++ code. In addition to the development of new diagnostics, we continue improving Data-Flow analysis that enables old diagnostics find more bugs. Thanks to these improvements, the analyzer finds more interesting errors, like the one we described in the article "February 31". Download and try PVS-Studio.

CppCon 2017: Going Nowhere Faster--Chandler Carruth

By Adrien Hamelin | Jun 13, 2018 12:56 PM | Tags: performance

Have you registered for CppCon 2018 in September? Early bird registration is open now.

While we wait for this year’s event, we’re featuring videos of some of the 100+ talks from CppCon 2017 for you to enjoy. Here is today’s feature:

Going Nowhere Faster

by Chandler Carruth

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

You care about the performance of your C++ code. You have followed basic patterns to make your C++ code efficient. You profiled your application or server and used the appropriate algorithms to minimize how much work is done and the appropriate data structures to make it fast. You even have reliable benchmarks to cover the most critical and important parts of the system for performance. But you're profiling the benchmark and need to squeeze even more performance out of it... What next?

This talk dives into the performance and optimization concerns of the important, performance critical loops in your program. How do modern CPUs execute these loops, and what influences their performance? What can you do to make them faster? How can you leverage the C++ compiler to do this while keeping the code maintainable and clean? What optimization techniques do modern compilers make available to you? We'll cover all of this and more, with piles of code, examples, and even live demo.

While the talk will focus somewhat on x86 processors and the LLVM compiler, but everything will be broadly applicable and basic mappings for other processors and toolchains will be discussed throughout. However, be prepared for a lot of C++ code and assembly.
