Jonathan Peyton 5de1d47ef5 Suppress uninitialized-variable-is-used warning in kmp_csupport.c
The following change is needed to suppress the "variable 'retval' is used 
uninitialized whenever 'if' condition is false" warnings in runtime/src/kmp_csupport.c.
This change just initializes 'retval' to 0.

Jonathan Peyton c98d03011e Reorder C++ initialization lists to appease compiler.
in kmp_wait_release.h, there were some constructors where the initialization
lists were out of order with the member declarations inside the class.  This
patch just reorders the initialization list so the compiler doesn't complain.

Jonathan Peyton 32be447d55 Apply name change to Makefile build system.

Jonathan Peyton 227e1aeb13 Apply name change to CMake build system.
This change has the CMake build system create a dynamic library named
libomp instead of libiomp5.  Also any reference to libiomp is replaced
with libomp.  One can still use the LIBOMP_LIB_NAME variable to enforce
a different name, and everything will still work as expected.  An important
note is that libiomp5 and libgomp symlinks are created at install time when
on Unix systems.  On Windows, copies are created with the legacy names.

Jonathan Peyton 92907c2ab9 Allow CMAKE_OSX_ARCHITECTURES to build fat library.
The CMAKE_OSX_ARCHITECTURES CMake variable allows users to build
universal fat libraries that contain both i386 and x86_64 code.  These
changes allow this build by having the z_Linux_asm.s file detect the architecture
itself instead of receiving it through the build system.

Also, there was a LIBOMP_OSX_ARCHITECTURES CMake variable added to allow
people to only build libomp as a fat library and not the entire LLVM/Clang system.

Jonathan Peyton 057d77d8c1 Fix task team synchronization
The fix simply syncs up the new threads to have the same task_state and
task_team as the old threads.  The master thread is skipped,
because it shouldn't at this point have the team's task_team value yet
-- it should still have parent_team's task_team.  It gets pointed at
the new team's task_team later, after __kmp_allocate_team returns, and
the master has stored a memo of it's old task_state.

Cached CMake variables need to have a prefix so they don't collide with other
projects. This change (a lot of simple changes) simply prefixes cached variables
with LIBOMP_ and sets all of these variables to UPPERCASE which is convention.
e.g., os => LIBOMP_OS, ompt_support => LIBOMP_OMPT_SUPPORT.

Andrey Churbanov 648467ed05 Integrate libiomp CMake into LLVM CMake build system.
This patch integrates the libiomp CMake build system into the LLVM CMake build 
system so that users can checkout libiomp into the projects directory of llvm 
and build llvm,clang, and libiomp all together.  These changes specifically 
introduce a new install target which will put libraries and headers into the 
correct locations when either a standalone build or part of llvm.
The copy_recipe() method has been removed in favor of the POST_BUILD method 
to move headers into the exports subdirectory.  And lastly, the MicroTests.cmake 
file was refactored which led to simpler target dependencies and a new target, 
make libiomp-micro-tests, which performs the 5 small tests (test-relo, 
test-touch, etc.) when called.

Jim Cownie 4cc4bb4c60 I apologise in advance for the size of this check-in. At Intel we do
understand that this is not friendly, and are working to change our
internal code-development to make it easier to make development
features available more frequently and in finer (more functional)
chunks. Unfortunately we haven't got that in place yet, and unpicking
this into multiple separate check-ins would be non-trivial, so please
bear with me on this one. We should be better in the future.

Apologies over, what do we have here?

GGC 4.9 compatibility
--------------------
* We have implemented the new entrypoints used by code compiled by GCC
4.9 to implement the same functionality in gcc 4.8. Therefore code
compiled with gcc 4.9 that used to work will continue to do so.
However, there are some other new entrypoints (associated with task
cancellation) which are not implemented. Therefore user code compiled
by gcc 4.9 that uses these new features will not link against the LLVM
runtime. (It remains unclear how to handle those entrypoints, since
the GCC interface has potentially unpleasant performance implications
for join barriers even when cancellation is not used)

--- new parallel entry points ---
new entry points that aren't OpenMP 4.0 related
These are implemented fully :-
      GOMP_parallel_loop_dynamic()
      GOMP_parallel_loop_guided()
      GOMP_parallel_loop_runtime()
      GOMP_parallel_loop_static()
      GOMP_parallel_sections()
      GOMP_parallel()

--- cancellation entry points ---
Currently, these only give a runtime error if OMP_CANCELLATION is true
because our plain barriers don't check for cancellation while waiting
        GOMP_barrier_cancel()
        GOMP_cancel()
        GOMP_cancellation_point()
        GOMP_loop_end_cancel()
        GOMP_sections_end_cancel()

--- taskgroup entry points ---
These are implemented fully.
      GOMP_taskgroup_start()
      GOMP_taskgroup_end()

--- target entry points ---
These are empty (as they are in libgomp)
     GOMP_target()
     GOMP_target_data()
     GOMP_target_end_data()
     GOMP_target_update()
     GOMP_teams()

Improvements in Barriers and Fork/Join
--------------------------------------
* Barrier and fork/join code is now in its own file (which makes it
easier to understand and modify).
* Wait/release code is now templated and in its own file; suspend/resume code is also templated
* There's a new, hierarchical, barrier, which exploits the
cache-hierarchy of the Intel(r) Xeon Phi(tm) coprocessor to improve
fork/join and barrier performance.

***BEWARE*** the new source files have *not* been added to the legacy
Cmake build system. If you want to use that fixes wil be required.

Statistics Collection Code
--------------------------
* New code has been added to collect application statistics (if this
is enabled at library compile time; by default it is not). The
statistics code itself is generally useful, the lightweight timing
code uses the X86 rdtsc instruction, so will require changes for other
architectures.
The intent of this code is not for users to tune their codes but
rather 
1) For timing code-paths inside the runtime
2) For gathering general properties of OpenMP codes to focus attention
on which OpenMP features are most used. 

Nested Hot Teams
----------------
* The runtime now maintains more state to reduce the overhead of
creating and destroying inner parallel teams. This improves the
performance of code that repeatedly uses nested parallelism with the
same resource allocation. Set the new KMP_HOT_TEAMS_MAX_LEVEL
envirable to a depth to enable this (and, of course, OMP_NESTED=true
to enable nested parallelism at all).

Improved Intel(r) VTune(Tm) Amplifier support
---------------------------------------------
* The runtime provides additional information to Vtune via the
itt_notify interface to allow it to display better OpenMP specific
analyses of load-imbalance.

Support for OpenMP Composite Statements
---------------------------------------
* Implement new entrypoints required by some of the OpenMP 4.1
composite statements.

Improved ifdefs
---------------
* More separation of concepts ("Does this platform do X?") from
platforms ("Are we compiling for platform Y?"), which should simplify
future porting.


ScaleMP* contribution
---------------------
Stack padding to improve the performance in their environment where
cross-node coherency is managed at the page level.

Redesign of wait and release code
---------------------------------
The code is simplified and performance improved.

Bug Fixes
---------
    *Fixes for Windows multiple processor groups.
    *Fix Fortran module build on Linux: offload attribute added.
    *Fix entry names for distribute-parallel-loop construct to be consistent with the compiler codegen.
    *Fix an inconsistent error message for KMP_PLACE_THREADS environment variable.

CMAKE buld system should meet everyone's requirements.

Enhanced CMake Build System Commit 

* Supports Linux, Mac, Windows, and Intel® Xeon Phi builds
* Supports building with gcc, icc, clang, and Visual Studio compilers
* Supports bulding "fat" libraries on OS/X with clang
* Details and documentation on how to use build system 
  are in Build_With_CMake.txt
* To use the old CMake build system (corresponds to 
  CMakeLists.txt.old), just rename CMakeLists.txt to
  CMakeLists.txt.other and rename CMakeLists.txt.old to
  CMakeLists.txt

This is not yet supported for production builds but can already produce working
binaries on OS X and Linux with clang and gcc.

The intention is to improve support to the point where it can integrate with
the LLVM runtime platform, cover all platforms, runtime/release build
configurations and run the tests.

Alp Toker 98758b09c8 Make affinity support conditional on KMP_AFFINITY_SUPPORTED
The feature was previously guarded with KMP_OS_LINUX || KMP_OS_WINDOWS but can
now be enabled/disabled independently to simplify porting.

Completes the work started in r202478.

Port the OpenMP runtime to FreeBSD along with associated build system changes.

Also begin to generalize affinity capabilities so they aren't tied explicitly

The port builds with stock clang and gmake and has no additional runtime
dependencies.

All but a handful of the validation suite tests are now passing on FreeBSD 10
x86_64.

Alp Toker 0032b4d519 clang build fix: don't check for gnu tools by default
gcc/g++ don't exist on modern OS X development environments so the failed
checks for gcc were causing the build to break even with 'make compiler=clang'.

(The rationale for the check refers to a file 'touch-test.c' which no longer
exists in the codebase.)
