http://llvm.org/bugs/show_bug.cgi?id=22060 this may cause some PIC codes fail,works for 3.5, seems regression。
I've come across 2 regressions: http://llvm.org/bugs/show_bug.cgi?id=22405 prevents using PCH with 3.6 Support headers, and http://llvm.org/bugs/show_bug.cgi?id=22385 breaking RefactoringTool when rewriting sources in a subdirectory.
If it's not too late and there's no bot fallout in the near future, I think we should get r227983 ( http://llvm.org/viewvc/llvm-project?view=revision&revision=227983 ) into the branch. It is effectively a reversion of r224330 ( http://llvm.org/viewvc/llvm-project?view=revision&revision=224330 ) and part of the fix for bug 22371.
Maybe http://llvm.org/bugs/show_bug.cgi?id=22293 is for your list, it crashes the compiler.
At risk of being a presumptuous ass, I'm adding 22506 and 22513 to the list here in case it missed anyone's radar. IMHO, 22506 *definitely* needs to be fixed; there was some discussion on IRC as to whether a bug which appears to only crop up with Polly (though it's not clear to me that its necessarily a *Polly bug*, per se) should be considered a release blocker, so (obviously) feel free to demote it if you see fit.
Sorry, that last bit was in reference to 22513.
