            Bug ID: 111547
           Summary: [OpenMP] -fopenmp omp::decl update missing
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Keywords: documentation
          Severity: normal
          Priority: P3
         Component: middle-end
          Assignee: unassigned at gcc dot gnu.org
          Reporter: burnus at gcc dot gnu.org
                CC: jakub at gcc dot gnu.org
  Target Milestone: ---

We need to add omp::decl to invoke.texi:

@item -fopenmp
Enable handling of OpenMP directives @code{#pragma omp} in C/C++,
@code{[[omp::directive(...)]]} and @code{[[omp::sequence(...)]]} in C++ and
@code{!$omp} in Fortran.

and

@item -fopenmp-simd
Enable handling of OpenMP's @code{simd}, @code{declare simd},
@code{declare reduction}, @code{assume}, @code{ordered}, @code{scan},
@code{loop} directives and combined or composite directives with
@code{simd} as constituent with @code{#pragma omp} in C/C++,
@code{[[omp::directive(...)]]} and @code{[[omp::sequence(...)]]} in C++
and @code{!$omp} in Fortran.=20

How do we handle 'loop' for the here? It sounds either wrong or misleading;=
 it
surely does not imply multiple threads here.=
