6beeb09142 Pull in r185594 from llvm trunk:
Add MachineBasicBlock::addLiveIn().

  This function adds a live-in physical register to an MBB and ensures
  that it is copied to a virtual register immediately.

Pull in r185615 from llvm trunk:

  Live-in copies go *after* EH_LABELs.

  This will soon be tested by exception handling working at all.

Pull in r185617 from llvm trunk:

  Simplify landing pad lowering.

  Stop using the ISD::EXCEPTIONADDR and ISD::EHSELECTION when lowering
  landing pad arguments. These nodes were previously legalized into
  CopyFromReg nodes, but that never worked properly because the
  CopyFromReg node weren't guaranteed to be  scheduled at the top of the
  basic block.

  This meant the exception pointer and selector registers could be
  clobbered before being copied to a virtual register.

  This patch copies the two physical registers to virtual registers at
  the beginning of the basic block, and lowers the landingpad instruction
  directly to two CopyFromReg nodes reading the *virtual* registers. This
  is safe because virtual registers don't get clobbered.

  A future patch will remove the ISD::EXCEPTIONADDR and ISD::EHSELECTION
  nodes.

Together, these changes fix llvm PR 16038 ('qt4 webcore file results in
"Bad machine code: Using an undefined physical register"'), and should
make it possible again to compile the www/qt4-webkit port again on the
i386 arch, without using a CPUTYPE=i686 or higher setting.

3861d79fd7 Upgrade our copy of llvm/clang to r168974, from upstream's release_32
branch.  This is effectively llvm/clang 3.2 RC2; the 3.2 release is
coming soon.

6239851166 Pull in r164132 from upstream llvm trunk:
When creating MCAsmBackend pass the CPU string as well. In X86AsmBackend
  store this and use it to not emit long nops when the CPU is geode which
  doesnt support them.

  Fixes PR11212.

Pull in r164133 from upstream clang trunk:

  Follow up on llvm r164132.

This should prevent illegal instructions when building world on Geode
CPUs (e.g. Soekris).

96ccbf68a6 Pull in r156591 from upstream llvm trunk:
Allow unique_file to take a mode for file permissions, but default
  to user only read/write.

and r156592 from upstream clang trunk:

  For final output files create them with mode 0664 to match other
  compilers and expected defaults.

This should fix clang creating files with mode 0600.

dd6029ff3a Update llvm/clang to trunk r126547.
There are several bugfixes in this update, but the most important one is
to ensure __start_ and __stop_ symbols for linker sets and kernel module
metadata are always emitted in object files:

  http://llvm.org/bugs/show_bug.cgi?id=9292

Before this fix, if you compiled kernel modules with clang, they would
not be properly processed by kldxref, and if they had any dependencies,
the kernel would fail to load those.  Another problem occurred when
attempting to mount a tmpfs filesystem, which would result in 'operation
not supported by device'.

361680a519 Remove more unneeded files and directories from contrib/llvm. This
still allows us to build tblgen and clang, and further reduces the
footprint in the tree.

ffd1746d03 Upgrade our Clang in base to r108428.
This commit merges the latest LLVM sources from the vendor space. It
also updates the build glue to match the new sources. Clang's version
number is changed to match LLVM's, which means /usr/include/clang/2.0
has been renamed to /usr/include/clang/2.8.
