This has been a bumpier ride than 3.6 so far, mainly due to the cmake
switch. We're testing stuff that didn't get tested before, which I
think is good. Thank you very much for your efforts so far.

This is an attempt to summarize this rather long thread. TL;DR: There
have been a bunch of issues, many addressed, some still out-standing.
Most binaries are ready, so I plan to push RC1 to the web site soon.

Binaries on the sftp:
=====================
clang+llvm-3.7.0-armv7a-linux-gnueabihf.tar.xz
clang+llvm-3.7.0-rc1-aarch64-linux-gnu.tar.xz
clang+llvm-3.7.0-rc1-amd64-unknown-freebsd10.tar.xz
clang+llvm-3.7.0-rc1-i386-unknown-freebsd10.tar.xz
clang+llvm-3.7.0-rc1-mipsel-linux-gnu.tar.xz
clang+llvm-3.7.0-rc1-mips-linux-gnu.tar.xz
clang+llvm-3.7.0-rc1-x86_64-apple-darwin.tar.xz
clang+llvm-3.7.0-rc1-x86_64-linux-gnu-ubuntu-15.04.tar.xz
LLVM-3.7.0-rc1-win32.exe
LLVM-3.7.0-rc1-win64.exe

Some of these have the /usr/local prefix baked in (since fixed in
r242706); I'll remove that manually before publishing the tarballs.

The armv7a tarball doesn't have rc1 in the name. I'll rename that (and
the dir within) before publishing.

Fedora and OpenSUSE isn't ready yet, but those can be added later. I
think we have enough binaries to put RC1 on the web page.

Issues
======
Various compiler-rt test failures, see below.
(Linux/signal_segv_handler.cc might be fixed by r242848.)

Dimitry says he'll use the autoconf build for FreeBSD due to errors.
Has a patch out to do this in the script, but it hasn't landed yet.
(Darwin currently also defaults to autoconf in the script)

Jack Howarth asked about -fopenmp currently essentially being no-op.
As far as I know (please correct me if I'm wrong here) this is still
the case on trunk. If it's not enabled on trunk, there is nothing to
merge.

There is a discussion on openmp-dev about the CMake build being broken
in Pathscale's build. The breakage does not seem to be well understood
yet.

Nikola reports that compiler-rt fails to cmake on x86 openSUSE because
it targets i686, but the system is i586. Same failure happens on the
phase 2 build on x86 Fedora 22, but probably with a different cause.

Renato reported libunwind was missing from the projects list,
preventing libcxxabi and libcxx to build. It was added in r242543, but
there are still problems and Renato said he'll exclude them for this
release.

Files in the tarball were prefixed with /usr/local; fixed in r242706.

The clean_rpath function was failing when no rpath was present in the
binary; fixed in r242722

The file comparison step was broken as cmp(1) doesn't support
--ignore-initial on all platforms; fixed in r242721.

Object/archive-extract.test failed on windows; fixed in r242527

Ben reports that he didn't get a tarball even after the rpath fix and
had to disable -o pipefail to get one. Still not sure what caused
this.



Thanks,
Hans
