I plan to merge the alias-improvements branch next weekend (in 7 days) if all goes well. I will do bootstrap & regtesting on the archs I have available (x86_64, i?86, ppc, ppc64, ia64, s390 and s390x).
During the next week I will try to extract all bugfixes from the branch and apply them separately. I will also post a merge diff upfront (I hope it isn't too big), but diffing the branch against the last trunk revision that it was merged is of course possible as well in case you want to review it (it now only contains middle-end changes, so technically I do not need approval, and thanks to Diego most changes already got one review). There is ongoing compile-time and runtime performance measurements on x86_64 with acceptable results (faster compile-time, overall slight improvements in SPEC numbers), I do not plan to add to that - volunteers are welcome for other architectures, but as this is tree level changes I do not expect architecture specific differences. I will announce the time I am doing the last trunk -> alias-improvements branch merge and freeze the trunk for that. Thus, this is a heads-up - if I collide with your planned merge schedule just tell me and we can sort it out. Thanks, Richard.
