I have merged mainline @137837 into the branch. Jakub reports:
I don't have a testsuite_summary log from after the PRE commit but before this merge, only summary from yesterday. There are many tests fixed (most of them likely because of the PRE merge) and several regressions (again, likely culprit will be PRE or invalid gimple PRE is upset about), but your merge together with http://gcc.gnu.org/ml/gcc-patches/2008-07/msg01066.html bootstrapped fine and we can IMHO deal with the regressions tomorrow Jakub, thanks for testing the merge.
