Peter Zotov 1f00ac9368 [OCaml] Use $CAMLORIGIN, an rpath-$ORIGIN-like mechanism in OCaml.
As a result, installations of LLVM in non-standard locations
will not require passing custom -ccopt -L flags when building
the binary, nor absolute paths would be embedded in the cma/cmxa
files. Additionally, the executables will not require changes
to LD_LIBRARY_PATH, although CAML_LD_LIBRARY_PATH still
has to be set for ocamlc without -custom.

See http://caml.inria.fr/mantis/view.php?id=6642.
Note that the patch is approved, but not merged yet.
It will be released in 4.03 and likely 4.02.

Chandler Carruth cab512d629 [go] Teach the go cmake build functions to funnel the include directories down into the cgo-setup variables of llvm-go.
Summary:
This in turn allows us to use #includes with cgo that rely on CMake
provided include directories which is particularly useful for handling
generated headers that aren't reasonable to put in an "installable"
location.

Chandler Carruth ab8df0b6c6 [cmake] Push LLVM_LIBDIR_SUFFIX through to the LLVMConfig.cmake file
that is used by other projects to build against LLVM. This will allow
subsequent patches to them to use LLVM_LIBDIR_SUFFIX, both when built as
part of the larger LLVM build an as part of a standalone build against
an installed set of LLVM libraries.

Chandler Carruth a78e24e548 [cmake] Start making LLVM_LIBDIR_SUFFIX effective by adding it to
*numerous* places where it was missing in the CMake build. The primary
change here is that the suffix is now actually used for all of the lib
directories in the LLVM project's CMake. The various subprojects still
need similar treatment.

This is the first of a series of commits to try to make LLVM's cmake
effective in a multilib Linux installation. I don't think many people
are seriously using this variable so I'm hoping the fallout will be
minimal. A somewhat unfortunate consequence of the nature of these
commits is that until I land all of them, they will in part make the
brokenness of our multilib support more apparant. At the end, things
should actually work.

Peter Zotov f94eed6083 [cmake] Unbreak LLVM-Config.cmake / llvm_expand_dependencies.
The algorithm for sorting libraries in topological order, as
previously implemented, had a few issues:
  * It didn't make any sense.
  * It didn't actually sort libraries in topological order.
  * It hung on some inputs, e.g. "LLVMipo".

This commit replaces the old algorithm with a straightforward port
from llvm-config.cpp.

Rafael Espindola f9dcf9029b Pass PRIVATE to target_link_libraries if using shared libraries.
A shared library (unlike a .a), has its dependencies recorded in the library and
we can pass PRIVATE to target_link_libraries.

This patch then removes some bogus dependencies when using
BUILD_SHARED_LIBS=ON. For example, we go from

build lib/CodeGen/CMakeFiles/LLVMCodeGen.dir/AggressiveAntiDepBreaker.cpp.o:
CXX_COMPILER /home/espindola/llvm/llvm/lib/CodeGen/AggressiveAntiDepBreaker.cpp
|| include/llvm/IR/intrinsics_gen lib/libLLVMSupport.so
lib/libLLVMCore.so lib/libLLVMBitReader.so
lib/libLLVMTransformUtils.so lib/libLLVMInstCombine.so
lib/libLLVMScalarOpts.so lib/libLLVMipa.so lib/libLLVMAnalysis.so
lib/libLLVMMCParser.so lib/libLLVMMC.so lib/libLLVMObject.so
lib/libLLVMTarget.so lib/libLLVMProfileData.so

to

build lib/CodeGen/CMakeFiles/LLVMCodeGen.dir/AggressiveAntiDepBreaker.cpp.o:
CXX_COMPILER /home/espindola/llvm/llvm/lib/CodeGen/AggressiveAntiDepBreaker.cpp
|| include/llvm/IR/intrinsics_gen lib/libLLVMSupport.so
lib/libLLVMCore.so lib/libLLVMTransformUtils.so
lib/libLLVMScalarOpts.so lib/libLLVMAnalysis.so lib/libLLVMMC.so
lib/libLLVMTarget.so

In fact, build.ninja goes from 5231028 bytes to 4896759 bytes.

With this, old verisons of bfd ld (2.24 is OK, 2.23 warns) will print a bogus
warning when building with BUILD_SHARED_LIBS.

Reid Kleckner 19cb171ee1 Suppress MSVC's equivalent of -Wshadow warnings
IMO we need to clean up some of these, but the member variable one
(C4458) has false positives on static methods.  It is currently firing
on Twine, which has a static method like:
  struct Twine {
    uintptr_t LHS, RHS;
    static void staticMethod() {
      // warning C4458: declaration of 'LHS' hides class member
      uintptr_t LHS;
      ...
    }
  };

We should fix up clang's -Wshadow and clean it up, and then we can
re-enable some of these MSVC warnings.

This change modifies fatal signal handler used in LLVM tools.
Now it attempts to find llvm-symbolizer binary and communicates
with it in order to turn instruction addresses into
function/file/line info entries. This should significantly improve
stack traces readability in Debug builds.

This feature only works on selected platforms (including Darwin
and Linux). If the symbolization fails for some reason, signal
handler will fallback to the original behavior.
