Upcoming features in GCC 6

The Red Hat developer blog looksat what's coming in version 6 of the GNU Compiler Collection."The x86/x86_64 is a segmented memory architecture, yet GCC haslargely ignored this aspect of the Intel architecture and relied onimplicit segment registers. Low level code such as the Linux kernel &glibc often have to be aware of the segmented architecture and havetraditionally resorted to asm statements to use explicit segment registersfor memory accesses. Starting with GCC 6, variables may be declared asbeing relative to a particular segment. Explicit segment registers willthen be used to access those variables in memory." The GCC 6release can be expected sometime around April.
