2022-09-19[OpenMP] Add LoongArch64 supportSignKirigami1-0/+1
GCC, glibc, binutils, and LLVM have added support for LoongArch64. This patch adds support for LLVM OpenMP following D59880 for RISCV64. Reviewed By: MaskRay, SixWeining Differential Revision: https://reviews.llvm.org/D132925
2019-07-25[OpenMP] RISCV64 portJonas Hahnfeld1-0/+1
This is a port of libomp for the RISC-V 64-bit Linux target. We have tested this port on a HiFive Unleashed development board using a downstream LLVM that has support for the missing bits in upstream. As of now, all tests are passing, including OMPT. Patch by Ferran Pallarès! Differential Revision: https://reviews.llvm.org/D59880 llvm-svn: 367021
2017-12-27Unify build documentation and convert to reStructuredTextJonas Hahnfeld1-1/+1
We now have several options that apply for both libraries and they shouldn't be documented in multiple files. When already merging the two Build_With_CMake.txt documents, convert them to reStructuredText which is used for all of LLVM's documentation.

2015-09-14Removing the Makefile/Perl build system.Jonathan Peyton1-72/+30
This change deletes the Makefile+Perl build system and all files used by it which aren't used by the CMake build system. This included many Perl files, *.mk files, iomp* files. This change also updates the README's and index.html to instruct the user to use the CMake build system. All mentioning of the Perl+Makefile based system are removed.

2014-10-07I apologise in advance for the size of this check-in. At Intel we doJim Cownie1-12/+20
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. llvm-svn: 219214
2014-06-01Add initial CMake build systemAlp Toker1-1/+5
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. Patch by Jack Howarth! llvm-svn: 209994
2014-02-28Add support for FreeBSDAlp Toker1-0/+1
Port the OpenMP runtime to FreeBSD along with associated build system changes. Also begin to generalize affinity capabilities so they aren't tied explicitly to Windows and Linux. 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. llvm-svn: 202478
2013-12-23For your Christmas hacking pleasure.Jim Cownie1-7/+15
This release use aligns with Intel(r) Composer XE 2013 SP1 Product Update 2 New features * The library can now be built with clang (though wiht some limitations since clang does not support 128 bit floats) * Support for Vtune analysis of load imbalance * Code contribution from Steven Noonan to build the runtime for ARM* architecture processors * First implementation of runtime API for OpenMP cancellation Bug Fixes * Fixed hang on Windows (only) when using KMP_BLOCKTIME=0 llvm-svn: 197914
