Mac OS X 10.6 Snow Leopard: the Ars Technica review
In June of 2004, during the WWDC keynote address, Steve Jobs revealed Mac OS X 10.4 Tiger to developers and the public for the first time. When the finished product arrived in April of 2005, Tiger was the biggest, most important, most feature-packed release in the history of Mac OS X by a wide margin. Apple's marketing campaign reflected this, touting "over 150 new features." All those new feature
rkd.me.uk - Clang vs. GCC - code coverage checking
April 2, 2016 Recently, I've been compiling some of the codebases I work on under Clang 3.8 instead of GCC 4.8, to take advantage of better compiler warnings and faster compilation speed (I've seen a 33% speedup, though I haven't tested this rigorously). Today, I got to grips with llvm-cov-3.8, and checked the coverage of my Clang-compiled test suite - and saw coverage failures, on a test suite I

How much do __builtin_expect(), likely(), and unlikely() improve performance?
How much do __builtin_expect(), likely(), and unlikely() improve performance? I got curious about how much __builtin_expect() helps performance and when its use is justified, so wrote a small test program to study its effects. As the gcc documentation says, you can use this compiler built-in function to give the optimizer a clue about the likely result of an integer (or Boolean) expression. In the

Why is FreeBSD deprecating GCC in favor of Clang/LLVM?
Summary: The primary reason for switching from GCC to Clang is the incompatibility of GCC's GPL v3 license with the goals of the FreeBSD project. There are also political issues to do with corporate investment, as well as user base requirements. Finally, there are expected technical advantages to do with standards compliance and ease of debugging. Real world performance improvements in compilation

Introduction¶ This document describes the language extensions provided by Clang. In addition to the language extensions listed here, Clang aims to support a broad range of GCC extensions. Please see the GCC manual for more information on these extensions. Feature Checking Macros¶ Language extensions can be very useful, but only if you know you can depend on them.
