When you use generator expressions in a library sources list,
and then later access the SOURCES property, the OLD behavior
(CMake 3.0 and earlier) would not include these expressions in
the SOURCES property.  The NEW behavior (starting in CMake 3.1)
is that they do include the generator expressions in the SOURCES
property.

The builder is based on a layout algorithm that tries to keep members of
small bit sets together. The new layout compresses Chromium's bit sets to
around 15% of their original size.

This resubmits r230380.  The primary cause of the failure was

a clean.

Most of the checks in these two tests were actually testing the

specifically in LLVM's test suite, it's better if we only test the

This test checks that the symbols instrprof creates have appropriate
linkage. The tests already exist in clang in a slightly different form
from before we sunk profile generation into an LLVM pass, but that's
an awkward place for them now. I'll remove/simplify the clang versions
shortly.

An OBJECT library is a special type of CMake library that produces
no archive, has no link interface, and no link inputs.  It is like
a regular archive, just without the physical output.  To link
against an OBJECT library, you reference it in the *source* file
list of a library using the special syntax $<TARGET_OBJECTS:lldbAPI>.
This will cause every object file to be passed to the linker
independently, as opposed to a single archive being passed to the
linker.

This is *extremely* important on Windows.  lldbAPI exports all of the
SB classes using __declspec(dllexport).  Unfortunately for technical
reasons it is not possible (well, extremely difficult) to get the
linker to propagate a __declspec(dllexport) attribute from a symbol
in an object file in an archive to a DLL that links against that
archive.  The solution to this is for the DLL to link the object files
directly.  So lldbAPI must be an OBJECT library.

This fixes an issue that has been present since the duplicated
lldbAPI file lists were removed, which would cause linker failures.

As a side effect, this also makes LLDB_DISABLE_PYTHON=1 work again
on Windows, which was previously totally broken.

This is generating problems when you have built both debug and

TODO: The iwmmx register save & restore functions still need the same treatment.
      I didn't do that in this patch because the integrated assembler has a bug
      where it refuses to build them on -march=armv6-m, even with
         .march armv5t
         .arm
      in front of those functions.

In this change:
- Put the getting started section first
- Create a dedicated section to document the built in collector strategies
- Move discuss of ShadowStack into new section
- Add placeholders for erlang, ocaml, and statepoint-example collectors

There will be many more changes following.  I plan on full integrating the documentation for gc.statepoint and gc.root.  I want to make it much clearer on how to get started and what users should expect in terms of effort.

    [DagCombiner] Generalized BuildVector Vector Concatenation

    The CONCAT_VECTORS combiner pass can transform the concat of two BUILD_VECTOR nodes into a single BUILD_VECTOR node.

    This patch generalises this to support any number of BUILD_VECTOR nodes, and also permits UNDEF nodes to be included as well.

    This was noticed as AVX vec128 -> vec256 canonicalization sometimes creates a CONCAT_VECTOR with a real vec128 lower and an vec128 UNDEF upper.

The backend should now be able to handle all AAPCS rules based on argument
type, which means Clang no longer has to duplicate the register-counting logic
and the CodeGen can be significantly simplified.

llvm-svn: 230349

The logic is almost there already, with our special homogeneous aggregate
handling. Tweaking it like this allows front-ends to emit AAPCS compliant code
without ever having to count registers or add discarded padding arguments.

Only arrays of i32 and i64 are needed to model AAPCS rules, but I decided to
apply the logic to all integer arrays for more consistency.

Following 4 files have been removed. I have updated CMake files and checked that it builds
fine on Linux and Windows. Can somebody update the xcode related file accordingly?
