Upgrade our copy of llvm/clang to 3.4 release. This version supports all of the features in the current working draft of the upcoming C++ standard, provisionally named C++1y. The code generator's performance is greatly increased, and the loop auto-vectorizer is now enabled at -Os and -O2 in addition to -O3. The PowerPC backend has made several major improvements to code generation quality and compile time, and the X86, SPARC, ARM32, Aarch64 and SystemZ backends have all seen major feature work. Release notes for llvm and clang can be found here: <http://llvm.org/releases/3.4/docs/ReleaseNotes.html> <http://llvm.org/releases/3.4/tools/clang/docs/ReleaseNotes.html> MFC 262121 (by emaste): Update lldb for clang/llvm 3.4 import This commit largely restores the lldb source to the upstream r196259 snapshot with the addition of threaded inferior support and a few bug fixes. Specific upstream lldb revisions restored include: SVN git 181387 779e6ac 181703 7bef4e2 182099 b31044e 182650 f2dcf35 182683 0d91b80 183862 15c1774 183929 99447a6 184177 0b2934b 184948 4dc3761 184954 007e7bc 186990 eebd175 Sponsored by: DARPA, AFRL MFC 262186 (by emaste): Fix mismerge in r262121 A break statement was lost in the merge. The error had no functional impact, but restore it to reduce the diff against upstream. MFC 262303: Pull in r197521 from upstream clang trunk (by rdivacky): Use the integrated assembler by default on FreeBSD/ppc and ppc64. Requested by: jhibbits MFC 262611: Pull in r196874 from upstream llvm trunk: Fix a crash that occurs when PWD is invalid. MCJIT needs to be able to run in hostile environments, even when PWD is invalid. There's no need to crash MCJIT in this case. The obvious fix is to simply leave MCContext's CompilationDir empty when PWD can't be determined. This way, MCJIT clients, and other clients that link with LLVM don't need a valid working directory. If we do want to guarantee valid CompilationDir, that should be done only for clients of getCompilationDir(). This is as simple as checking for an empty string. The only current use of getCompilationDir is EmitGenDwarfInfo, which won't conceivably run with an invalid working dir. However, in the purely hypothetically and untestable case that this happens, the AT_comp_dir will be omitted from the compilation_unit DIE. This should help fix assertions occurring with ports-mgmt/tinderbox, when it is using jails, and sometimes invalidates clang's current working directory. Reported by: decke MFC 262809: Pull in r203007 from upstream clang trunk: Don't produce an alias between destructors with different calling conventions. Fixes pr19007. (Please note that is an LLVM PR identifier, not a FreeBSD one.) This should fix Firefox and/or libxul crashes (due to problems with regparm/stdcall calling conventions) on i386. Reported by: multiple users on freebsd-current PR: bin/187103 MFC 263048: Repair recognition of "CC" as an alias for the C++ compiler, since it was silently broken by upstream for a Windows-specific use-case. Apparently some versions of CMake still rely on this archaic feature... Reported by: rakuco MFC 263049: Garbage collect the old way of adding the libstdc++ include directories in clang's InitHeaderSearch.cpp. This has been superseded by David Chisnall's commit in r255321. Moreover, if libc++ is used, the libstdc++ include directories should not be in the search path at all. These directories are now only used if you pass -stdlib=libstdc++.
