Code review comment for lp:~ams-codesourcery/gcc-linaro/widening-multiplies-4.6

The patches are not yet committed upstream. The accepted versions of the patches are in the thread on the gcc-patches@ list, but I have not yet posted the bug-fixed versions.

Here are the originals:

I do not expect them to require further approval. I plan to do some tests on the 4.7 baseline, and then commit the patches and post the new versions with updated context and bug fixes, where they have changed.
