11.1. GCC Toolchain
In Red Hat Enterprise Linux 7.0 Beta, the gcc toolchain is based on the gcc-4.8.x release series, and includes numerous enhancements and bugfixes relative to the Red Hat Enterprise Linux 6 equivalent. Similarly, Red Hat Enterprise Linux 7 includes binutils-2.23.52.x.
These versions correspond to the equivalent tools in Red Hat Developer Toolset 2.0; a detailed comparison of Red Hat Enterprise Linux 6 and Red Hat Enterprise Linux 7 gcc and binutils versions can therefore be seen here:
