* Rename z_Linux_asm.s to z_Linux_asm.SDimitry Andric2017-07-111-1730/+0
| | | | | | | | | | | | | | | | | | | | | Summary: On Unix, a .S file is normally an assembly source which must be preprocessed with a C preprocessor, while a .s file is "plain" assembly. The former is handled by the compiler driver (cc), the latter is directly passed to the assembler binary (as). Because z_Linux_asm.s is supposed to be preprocessed, rename it to .S, so it can be automatically picked up correctly by build systems.

* Clang-format and whitespace cleanup of source codeJonathan Peyton2017-05-121-120/+22
| | | | | | | | | | | | | This patch contains the clang-format and cleanup of the entire code base. Some of clang-formats changes made the code look worse in places. A best effort was made to resolve the bulk of these problems, but many remain. Most of the problems were mangling line-breaks and tabbing of comments.

* Add an assembly __kmp_invoke_microtask for ppc64[le]Hal Finkel2016-05-261-0/+220
| | | | | | | | | Clang no longer restricts itself to generating microtasks with a small number of arguments, and so an assembly implementation is required to prevent hitting the parameter limit present in the C implementation. This adds an implementation for ppc64[le]. llvm-svn: 270821
* Remove trailing whitespace in src/ directoryJonathan Peyton2016-05-201-1/+1

* Solve 'Too many args to microtask' problemPaul Osmialowski2016-05-131-0/+141
| | | | | | | | | | | | | This patch solves 'Too many args to microtask' problem which occurs while executing lulesh2.0.3 benchmark on AArch64. To solve this I had to wrtite AArch64 assembly version of __kmp_invoke_microtask() function, similar to x86 and x86_64 implementations.

* [OpenMP] [CMake] Removing expand-vars.pl in favor of CMake's configure_file()Jonathan Peyton2015-08-281-1/+1
| | | | | | | | | | | | | | | | | | | Currently, the libomp CMake build system uses a Perl script to configure files (tools/expand-vars.pl). This patch replaces the use of the Perl script by using CMake's configure_file() function. The major changes include: 1. *.var has every $KMP_* variable changed to @LIBOMP_*@ 2. kmp_config.h.cmake is a new file which contains all the feature macros and #cmakedefine lines 3. Most of the -D lines have been moved from LibompDefinitions.cmake but some OS specific MACROs (e.g., _GNU_SOURCE) remain. 4. All expand-vars.pl related logic is removed from the CMake files. One important note about this change is that it breaks the old Perl+Makefile build system because it can't create kmp_config.h properly.

* Update z_Linux_asm.s to use platform macrosJonathan Peyton2015-08-201-19/+19
| | | | | | | | z_Linux_asm.s can use the KMP_OS_* / KMP_MIC macros instead of the predefined compiler macro checks. The macro logic to determine KMP_MIC is moved from kmp_os.h to kmp_platform.h. llvm-svn: 245602
* Allow CMAKE_OSX_ARCHITECTURES to build fat library.Jonathan Peyton2015-05-291-0/+2
| | | | | | | | | | | | | 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. http://lists.cs.uiuc.edu/pipermail/openmp-dev/2015-May/000626.html llvm-svn: 238566

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. llvm-svn: 219214
