Committed - looks like: https://gcc.gnu.org/projects/gomp/ esp, see "TR 12" and "OpenMP Releases and Status" Tobias PS: The libgomp.texi update is at https://gcc.gnu.org/onlinedocs/libgomp/OpenMP-Implementation-Status.html -> TR12 (I need to fix the typo 'c(a)lause' there) and some update for https://gcc.gnu.org/gcc-14/changes.html is also eventually required. But as more features keep getting added, there is no rush. ----------------- 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 commit ad756d3cfed3007d8c07c7f22facf24b202f1160 Author: Tobias Burnus Date: Mon Nov 13 10:23:25 2023 +0100 projects/gomp: Update for TR12, update impl. status This adds a link to the new TR12 (second OpenMP 6.0 preview); updates the status + TR12 to-do list form libgomp.texi and adds a couple of missing ''. --- htdocs/projects/gomp/index.html | 248 +++++++++++++++++++++++++++++++++------- 1 file changed, 205 insertions(+), 43 deletions(-) diff --git a/htdocs/projects/gomp/index.html b/htdocs/projects/gomp/index.html index 7f0b97c3..bc472747 100644 --- a/htdocs/projects/gomp/index.html +++ b/htdocs/projects/gomp/index.html @@ -29,7 +29,7 @@ OpenMP and OpenACC are supported with GCC's C, C++ and Fortran compilers.
