Upcoming features in GCC 6

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