Wording, technical and other comments are welcome as always. I intent to commit the attached patch tomorrow. Tobias PS: There were a bunch of other useful changes, but those "only" improved and fixed features already supported or added parsing-only support. Thus, while the former is important for users, it is not for the release notes. ----------------- Siemens Electronic Design Automation GmbH; Anschrift: Arnulfstraße 201, 80634 München; Gesellschaft mit beschränkter Haftung; Geschäftsführer: Thomas Heurung, Frank Thürauf; Sitz der Gesellschaft: München; Registergericht München, HRB 106955 gcc-14/changes.html + projects/gomp/: GCC 14 OpenMP update htdocs/gcc-14/changes.html | 15 +++++++++++++++ htdocs/projects/gomp/index.html | 10 ++++++---- 2 files changed, 21 insertions(+), 4 deletions(-) diff --git a/htdocs/gcc-14/changes.html b/htdocs/gcc-14/changes.html index 55d566b8..c403c94f 100644 --- a/htdocs/gcc-14/changes.html +++ b/htdocs/gcc-14/changes.html @@ -37,6 +37,21 @@ a work-in-progress.
