Hi all, @Fortraners: Comments to the added 'do concurrent' item?
@Thomas: Are you fine with this C++ wording? @Andrew: Likewise for C++ and ROCm bump? Anyone: comments are welcome. Affected pages: * https://gcc.gnu.org/gcc-15/changes.html * https://gcc.gnu.org/projects/gomp/ Cheers, Tobias
gcc-15/changes: Fortran + offload (C++) updated | project/gomp: GCC 15 update * The C++ support with offloading was extended; mention it under general improvements and for Nvptx/GCN (as libstdc++ is now build by default). * Generic support for AMD GPU required ROCm 6.4.0 - now released, we can name that version. * Fortran: 'do concurrent' locality-spec are now supported (local, local_init, shared, reduce, default(none). In projects/gomp, the impl.status links have been updated, esp. for GCC 15/16. htdocs/gcc-15/changes.html | 15 ++++++++++++--- htdocs/projects/gomp/index.html | 10 ++++++---- 2 files changed, 18 insertions(+), 7 deletions(-) diff --git a/htdocs/gcc-15/changes.html b/htdocs/gcc-15/changes.html index b4200df3..4e3c9b73 100644 --- a/htdocs/gcc-15/changes.html +++ b/htdocs/gcc-15/changes.html @@ -69,7 +69,8 @@ a work-in-progress.</p> <li> For offloading using OpenMP and OpenACC, issues preventing some host–device architecture combinations have been resolved.
