Hello all,

I installed all three patches on my mainline and 4.3 branch sources and
bootstrapped on IA64 Linux and HP-UX.  I did not see any regressions.
I also verified that the bug pr35659 goes away on the 4.3 branch when
the patches are applied.
In addition, I've bootstrapped and tested mainline, all default languages enabled, with the two control speculation patches applied and control speculation turned on by default via the ia64.opt file. I've verified by hand that the resulting cc1 binary has control speculative instructions. I haven't noticed any regressions compared with the recent gcc-testresults submissions, so I think control speculation patches should be okay. I will do the same today for the 4.3 branch tree.

Steve and Andrey, thank you both for testing these patches.
