In order to use this feature, configure LLVM as usual,
but then build and install it as:
make all install SYSTEM_LLVM_CONFIG=llvm-config
where llvm-config is the llvm-config binary installed on your
system (possibly llvm-config-VERSION on e.g. Debian).
llvm-svn: 225787
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.

Patch by Ramkumar Ramachandra <artagnon@gmail.com>.
Also remove Llvm_executionengine.get_pointer_to_global, as it
is actually deprecated and didn't appear in a stable release.
llvm-svn: 224801
Bindings built out-of-tree, e.g. via OPAM, should append
a line to META.llvm like the following:
linkopts = "-cclib -L$libdir -cclib -Wl,-rpath,$libdir"
where $libdir is the lib/ directory where LLVM libraries are
installed.

Since JIT->MCJIT migration, most of the ExecutionEngine interface
became deprecated and/or broken. This especially affected the OCaml
bindings, as runFunction is no longer available, and unlike in C,
it is not possible to coerce a pointer to a function and call it
in OCaml.
In practice, LLVM 3.5 shipped completely unusable
Llvm_executionengine.
The GenericValue interface and runFunction were essentially
a poor man's FFI. As such, this interface was removed and instead
a dependency on ctypes >=0.3 added, which handled platform-specific
aspects of accessing data and calling functions.
The new interface does not expose JIT (which is a shim around MCJIT),
as well as the interpreter (which can't handle a lot of valid IR).
Llvm_executionengine.add_global_mapping is currently unusable
due to PR20656.

This commit updates the OCaml bindings and tests to use ocamlfind.
The bindings are migrated in order to use ctypes, which are now
required for MCJIT-backed Llvm_executionengine.
The tests are migrated in order to use OUnit and to verify that
the distributed META.llvm allows to build working executables.
Every OCaml toolchain invocation is now chained through ocamlfind,
which (in theory) allows to cross-compile the OCaml bindings.
The configure script now checks for ctypes (>= 0.2.3) and
OUnit (>= 2). The code depending on these libraries will be added
later. The configure script does not check the package versions
in order to keep changes less invasive.
Additionally, OCaml bindings will now be automatically enabled
if ocamlfind is detected on the system, rather than ocamlc, as it
was before.

Pretend they do not exist using exists_if. This is better than
the current situation, which is the error:
Error: The external function `llvm_global_succ' is not available
but still somewhat confusing.
llvm-svn: 220845
In practice this means:
* Always using -g flag.
* Embedding -cclib -lstdc++ into the corresponding cma/cmxa file.
This also moves -lstdc++ in a single place.
* Using caml_named_value instead of a homegrown mechanism.

First, return true on success, as it is the OCaml convention.
Second, also initialize the native assembly printer, which is,
despite the name, required for MCJIT operation.
Since this function did not initialize the assembly printer earlier
and no function to initialize native assembly printer was available
elsewhere, it is safe to break its interface: it means that it
simply could not be used successfully before.

Merges equivalent loads on both sides of a hammock/diamond
and hoists into into the header.
Merges equivalent stores on both sides of a hammock/diamond
and sinks it to the footer.
Can enable if conversion and tolerate better load misses
and store operand latencies.
