-Subject: [PATCH] [cmake] Reintroduce (ldconfig-compatible) SOVERSIONs on
- shared libraries
-
-Reintroduce versioning of shared libraries via SOVERSION, addressing
-the issues with the previous design, since Gentoo is relying
-on shared-split install of LLVM. The SOVERSIONs were originally
-introduced in r229720 for all libraries, and removed in r252093 in favor
-of custom SONAME. As far as I understand, the major concern with the old
-versioning was that the used versions were incompatible with ldconfig.
-
-Having considered that, this commit introduce SOVERSIONS with the
-following considerations:
-
-1. SOVERSIONs are formed of major & minor version concatenated -- i.e.
-for 4.0 its .so.40. This matches the common practice where the first
-version number indicates ABI breakage, and therefore fixes the issues
-with ldconfig. Additionally, VERSION with the remaining verion
-components appended is used, however this is not strictly necessary.
-
-2. The versioning is only applied to libraries with no explicit SONAME
-specified -- i.e. it won't apply to libLLVM but only to the split
-libraries. It will also apply to libraries installed by the subprojects.
-
-3. The versioning is only done on *nix systems, Darwin excluded. This
-matches the current use of SONAME.

-Subject: [PATCH] Support setting default value for -rtlib at build time
-
-This patch introduces a new cmake variable: CLANG_DEFAULT_RTLIB, thru
-which we can specify a default value for -rtlib (libgcc or
-compiler-rt) at build time, just like how we set the default C++
-stdlib thru CLANG_DEFAULT_CXX_STDLIB.
-
-With these two options, we can configure clang to build binaries on
-Linux that have no runtime dependence on any gcc libs (libstdc++ or
-libgcc_s).
-
-Patch by Lei Zhang!

-
-[Driver] Support obtaining active toolchain from gcc-config on Gentoo
-
-Support using gcc-config to determine the correct GCC toolchain location
-on Gentoo. In order to do that, attempt to read gcc-config configuration
-form [[sysroot]]/etc/env.d/gcc, if no custom toolchain location is
-provided.
-
-Differential Revision: https://reviews.llvm.org/D25661

-git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@285074 91177308-0d34-0410-b5e6-96231b3b80d8
-
-[Driver] Fix finding multilib gcc install on Gentoo (with gcc-config)
-
-Fix the gcc-config code to support multilib gcc installs properly. This
-solves two problems: -mx32 using the 64-bit gcc directory (due to matching
-installation triple), and -m32 not respecting gcc-config at all (due to
-mismatched installation triple).
-
-In order to fix the former issue, split the multilib scan out of
-Generic_GCC::GCCInstallationDetector::ScanLibDirForGCCTriple() (the code
-is otherwise unchanged), and call it for each installation found via
-gcc-config.
-
-In order to fix the latter issue, split the gcc-config processing out of
-Generic_GCC::GCCInstallationDetector::init() and repeat it for all
-triples, including extra and biarch triples. The only change
-in the gcc-config code itself is adding the call to multilib scan.
-
-Convert the gentoo_linux_gcc_multi_version_tree test input to multilib
-x86_64+32+x32 install, and add appropriate tests to linux-header-search
-and linux-ld.

-Subject: [PATCH] llvm-config: Clean up exported values, update for shared
- linking
-
-Gentoo-specific fixup for llvm-config, including:
-- wiping build-specific CFLAGS, CXXFLAGS,
-- updating library suffixes for shared libs,
-- wiping --system-libs for shared linking,
-- making --src-root return invalid path (/dev/null),
-- making --build-mode return "Release" rather than "Gentoo".
-
-Thanks to Steven Newbury for the initial patch.
