+OpenMP Support
+==================
+
+Clang fully supports OpenMP 3.1 + some elements of OpenMP 4.5. Clang supports offloading to X86_64, AArch64, PPC64[LE] and Cuda devices.
+The status of major OpenMP 4.5 features support in Clang.
+
+Standalone directives
+=====================
+
+* #pragma omp [for] simd: :good:`Complete`.
+
+* #pragma omp declare simd: :partial:`Partial`.  We support parsing/semantic
+  analysis + generation of special attributes for X86 target, but still
+  missing the LLVM pass for vectorization.
+
+* #pragma omp taskloop [simd]: :good:`Complete`.
+
+* #pragma omp target [enter|exit] data: :good:`Mostly complete`.  Some rework is
+  required for better stability.
+
+* #pragma omp target update: :good:`Mostly complete`.  Some rework is
+  required for better stability.
+
+* #pragma omp target: :partial:`Partial`.  No support for the `reduction`,
+  `nowait` and `depend` clauses.
+
+* #pragma omp declare target: :partial:`Partial`.  No full codegen support.
+
+* #pragma omp teams: :good:`Complete`.
+
+* #pragma omp distribute [simd]: :good:`Complete`.
+
+* #pragma omp distribute parallel for [simd]: :good:`Complete`.
+
+Combined directives
+===================
+
+* #pragma omp parallel for simd: :good:`Complete`.
+
+* #pragma omp target parallel: :partial:`Partial`.  No support for the `reduction`,
+  `nowait` and `depend` clauses.
+
+* #pragma omp target parallel for [simd]: :partial:`Partial`.  No support for the `reduction`,
+  `nowait` and `depend` clauses.
+
+* #pragma omp target simd: :partial:`Partial`.  No support for the `reduction`,
+  `nowait` and `depend` clauses.
+
+* #pragma omp target teams: :partial:`Partial`.  No support for the `reduction`,
+  `nowait` and `depend` clauses.
+
+* #pragma omp teams distribute [simd]: :partial:`Partial`.  No full codegen support.
+
+* #pragma omp target teams distribute [simd]: :partial:`Partial`.  No full codegen support.
+
+* #pragma omp teams distribute parallel for [simd]: :partial:`Partial`.  No full codegen support.
+
+* #pragma omp target teams distribute parallel for [simd]: :partial:`Partial`.  No full codegen support.
+
+Clang does not support any constructs/updates from upcoming OpenMP 5.0 except for `reduction`-based clauses in the `task`-based directives.
