Looking At Changes In the Newest GCC
cyberpead writes "With GCC 4 comes a new optimization framework (and new intermediate code representation), new target and language support, and a variety of new attributes and options. Get to know the major new features and their benefits in this article."
That they were able to reduce it down to just one C. Now it's just GC.
But most developers still do not know the important differences between 4.x and 3.x other than the superficial ones like changes in headers that need to be included(ie stuff that breaks their code). For example, few seem to be aware that GCC does profile guided optimization now with -fprofile-generate and -fprofile-use switches(not even mentioned in the article).
You missed one of the largest improvements in the four series was time travel. This article was actually published two years ago.
The Slashdot team are now frantically searching for the wormhole in their office. This is also why there are so many dupes, articles keep popping down GCC invoked wormholes.
Really, Stallman is just messing with us for modding-up comments like this one.
The article is about 4.x, and covers everything including the latest 4.3.x series. It's very light on details, however, so unless you know next to nothing about GCC you are unlikely to learn anything.

Wouldn't it be more logical to start supporting C++ 98 first?
One of the things I personally am the most excited about is the ability to do function-level optimization in 4.4. Last year, I had a project that required me to have compiled code be as fast as possible, but you could only submit one source file and no Makefiles, which would be compiled with no arguments, optimizations, etc.. With this, I could throw the optimizations straight into the code, instead of having to compile with optimizations, taking the assembly, throwing that into a wrapper C file, and hoping the code was tested on the same architecture.
Seriously! From TFA:
Yeah, GCC 4 has more backends, the little slut.
Big deal about all this GCC4 stuff, let me know when GCC 4.x becomes available for MingW as an official build (or better yet, when the GCC community stops treating Windows builds of GCC as second class citizens)
