4.0.0-rc4 was just tagged from the branch at r297204.
This is very similar to rc3, with additional fixes for PR32142 and PR32153.
Please take it for a quick spin. If nothing new comes up, this is what
the final release will look like.
Built and tested on FreeBSD 10 without surprises. I have uploaded:
SHA256 (clang+llvm-4.0.0-rc4-i386-unknown-freebsd10.tar.xz) = a0d441c4003d7ab252148ffe37301f468942e1295084c8fe23753ce5a18615cc
SHA256 (clang+llvm-4.0.0-rc4-amd64-unknown-freebsd10.tar.xz) = d641a5bba15d8f10f9f04a48734a443ec70b40b57cc29dd3d3a600c6ef2ba540
Both ARM and AArch64 look good. The weird fluke on AArch64 is gone.
I'm running the final now.
