The previous Linaro GCC 4.5 release, 4.5-2011.01-0, suffered from a
build failure on x86_64, and PowerPC. ARM and x86 (32) were not
apparently affected, but users might like to upgrade to be on the safe side.
A bug fix toolchain, 4.5-2011.01-1 has now been released:
https://launchpad.net/gcc-linaro/4.5/4.5-2011.01-1
The -fshrink-wrap optimization and multiple load improvements have been
temporarily withdrawn.
This update refers to the GCC 4.5-based tools - the 4.4-based tools are
unaffected.
We apologise for the inconvenience.

The Linaro Toolchain Working Group is pleased to announce the release of
both Linaro GCC 4.4 and Linaro GCC 4.5.
Linaro GCC 4.4 is the sixth release in the 4.4 series. Based off the
latest GCC 4.4.5, it is a maintenance release that fixes one problem
found through use.
Linaro GCC 4.5 is the sixth release in the 4.5 series. Based off the
official GCC 4.5.2 release, it includes many ARM-focused performance
improvements and bug fixes.
Interesting changes include:
* Improved optimization of multiple load instructions, and
multiply-and-accumulate.
* -fshrink-wrap optimization for better use of function prologues and
epilogues.
* plus, various other bug fixes, and minor improvements.
