Jan Vesely c0ae1a038f build/cmake: Fix CMP0023 warning with libffi
Fixes:
CMake Warning (dev) at lib/ExecutionEngine/Interpreter/CMakeLists.txt:16 (target_link_libraries):
  Policy CMP0023 is not set: Plain and keyword target_link_libraries
  signatures cannot be mixed.  Run "cmake --help-policy CMP0023" for policy
  details.  Use the cmake_policy command to set the policy and suppress this
  warning.

  The keyword signature for target_link_libraries has already been used with
  the target "LLVMInterpreter".  All uses of target_link_libraries with a
  target should be either all-keyword or all-plain.

  The uses of the keyword signature are here:

   * cmake/modules/AddLLVM.cmake:345 (target_link_libraries)

Todd Fiala 6ce8fef458 Use the process' ReadCStringFromMemory from DYLDRendezvous::ReadStringFromMemory.
Tested:
Ubuntu 14.04 x86_64, clang-3.5-built lldb.
MacOSX 10.9.4, Xcode6-Beta7-built lldb.

Visual packet inspection on lldb <-> llgs shows significant reduction in overly-verbose
memory read traffic on start-up when scanning shared library info.

Change by Stephane Sezer.

Samuel Benzaquen ab005ed0c0 Refactor VariantMatcher::MatcherOps to reduce the amount of generated code.
Summary:
Refactor VariantMatcher::MatcherOps to reduce the amount of generated code.
 - Make some code type agnostic and move it to the cpp file.
 - Return a DynTypedMatcher instead of storing the object in MatcherOps.

This change reduces the number of symbols generated in Registry.cpp by
~19%, the object byte size by ~17% and the compilation time (in non-release mode) by ~20%.

Daniel Sanders ed39f58390 [mips] Zero-sized structs cannot be ignored in MipsABIInfo::classifyReturnType() for O32
Summary:
They are returned indirectly which causes the other arguments to move to
the next argument slot.

With this, utils/ABITest does not discover any failing cases in the first
500 attempts on big/little endian for O32. Previously some of these failed.
Also tested N32/N64 little endian (big endian has other known issues) with
no issues.

Tim Northover bb72e6c804 AArch64: fix big-endian immediate materialisation
We were materialising big-endian constants using DAG nodes with types different
from what was requested, followed by a bitcast. This is fine on little-endian
machines where bitcasting is a nop, but we need a slightly different
representation for big-endian. This adds a new set of NVCAST (natural-vector
cast) operations which are always nops.

Patch by Asiri Rathnayake.

Chandler Carruth 2e5134f8f4 [x86] Teach the new v4i32 shuffle lowering some more tricks to recognize
vzext patterns and insert-element patterns that for SSE4 have dedicated
instructions.

With this we can enable the experimental mode in a regression test that
happens to cover some of the past set of issues. You can see that the
new logic does significantly better here on the floating point cases.

A follow-up to this change and the previous ones will hoist the logic
into helpers so it can be shared across element type sizes as in this
particular case it generalizes cleanly.

mask. Added a bunch of tests for inserting into a zero-ish vector.

Chris Bieneman 5007741d68 Enabling LLVM & Clang to be cross-compiled using CMake from a single configuration command line
The basic idea is similar to the existing cross compilation support. A directory must be configured to build host versions of tablegen tools and llvm-config. This directory can be user provided (and configured), or it can be created during the build. During a build the native build directory will be configured and built to supply the tablegen tools used during the build. A user could also explicitly provide the tablegen executables to run on the CMake command line.

David Majnemer c6ab01ecca IndVarSimplify: Don't let LFTR compare against a poison value
LinearFunctionTestReplace tries to use the *next* indvar to compare
against when possible.  However, it may be the case that the calculation
for the next indvar has NUW/NSW flags and that it may only be safely
used inside the loop.  Using it in a comparison to calculate the exit
condition could result in observing poison.

This fixes PR20680.
