Release notes 

Linaro GCC 4.8 2013.10 is the seventh release in the 4.8 series. Based
off the latest GCC 4.8.1+svn203510 release, it includes performance
improvements and bug fixes.

Interesting changes include:
* Updates to GCC 4.8.1+svn203510
* Improved AArch64 support (CRC extension, improved intrinsics, gprof support)
* Improved Aarch32 support (bug fixes, better code generation,
  improved multilib)
* Backports for bug fixes (PR58578

We are aware that FSF GCC 4.8.2 was released earlier this week.
However, this release happened too late in our cycle for us to use it
as the basis for Linaro GCC 4.8 2013.10. The only functional
difference contained in FSF GCC 4.8.2 that is not in Linaro GCC 4.8
2013.10 is a correction to a x86 test case.
