Explore new features related to Valgrind's file descriptor and learn how to use them to track the file descriptors your program is using—or misusing.

A brief look at the changes needed to allow Valgrind Memcheck to produce correct diagnostics for memory issues in conjunction with x86-64-v3 instructions.

Part 3 in a series about improving Clang's constant expression interpreter.

A popular technique modern compilers use to improve the runtime performance of compiled code is to perform computations at compile time instead of at runtime. However, constant expressions need to be evaluated at compile time for a variety of reasons. To help resolve this problem, I've been working on improving the Clang's constant interpreter.

Timm Baeder explains the upstream work he has been doing on a new constant expression interpreter for Clang.

This short guide explains how to choose a GPU framework and library (e.g., CUDA vs. OpenCL), as well as how to design accurate benchmarks.
