[cfe-dev] last known good revision?

[Zhanyong Wan (λx.x x)]

Hi,

I synced llvm and clang to HEAD (r84204) and the build failed (looks
like the header declaring wait(int*) should be #included by
clang/tools/CIndex/CIndex.cpp but isn't).

Since it takes a lot of time to build llvm and clang after each sync,
it would be nice to avoid syncing to a broken revision.  Is there a
place that lists the last known good revision?  Thanks,
