It's worth celebrating (well, noting in an approving manner) this release. GCC is a foundation stone project for, well, a huge amount of the world's wealth.

It is a healthy project (even with CLang etc), and with the heartbleed post mortem on our minds we should probably ask what can be done to keep it and others healthy - auditing, foundation status etc.

So thank you GCC developers, for making sure I do not need to worry about something.

Bit strange comment; there are still plenty of bugs in GCC to worry about.

Any benchmarks? How does this compare with previous versions of gcc?

Does GCC support modules? http://clang.llvm.org/docs/Modules.html

gfortran which is part of GCC supports modules (this is because Fortran the language supports modules).

If you meant modules for C or C++, no (as far as I know), probably because C and C++ have no standard for modules. In a recent talk Bjarne Stroustroup talks about his hope that C++17 will include support for modules https://www.youtube.com/watch?v=2egL4y_VpYg

That's probably something one should keep in mind when writing micro-benchmarks.

It probably will once the C++ committee figures out how they want to do it...

There should be a warning for this enabled in every C project.

The release notes mention several benchmark comparisons.
