backport this page to release_60? I think the documented support
is also valid for 6.0 or did I miss recent commits that added
support for new directives / clauses?

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