GCC 5.1 Released

Posted by samzenpus on from the brand-new dept.

kthreadd writes: Version 5.1 of GCC, the primary free software compiler for GNU and other operating systems, has been released. Version 5 includes many changes from the 4.x series. Starting with this release the default compiler mode for C is gnu11 instead of the older gnu89. New features include new compiler warnings, support for Cilk Plus. There is a new attribute no_reorder which prevents reordering of selected symbols against other such symbols or inline assembler, enabling link-time optimization of the Linux kernel without having to use -fno-toplevel-reorder. Two new preprocessor directives have also been added, __has_include and __has_include_next, to test the availability of headers. Also, there's a new C++ ABI due to changes to libstdc++. The old ABI is however still supported and can be enabled using a macro. Other changes include full support for C++14. Also the Fortran frontend has received some improvements and users will now be able to have colorized diagnostics, and the Go frontend has been updated to the Go 1.4.2 release.

  1. No disrespect to GCC, but why not LLVM? by DoofusOfDeath · · Score: -1, Offtopic

    Given the nice, modular nature of LLVM, I would think even the GCC developers would find it to be a more enjoyable best to work on.

    Any idea why most GCC developers don't simply port their front-ends / back-ends of choice to LLVM, and walk away from GCC?

    I know there's the licensing issue, which I assume matters to some heavy-duty OSS advocates. But in my experience most programmers who work with OSS aren't super passionate about GPL vs. Berkeley -style licensing.
