It also fixes a couple of bugs and adds links providing more details for two items (a PR link as in libgomp.texi and a section in the manual). Comments? Suggestions? If not, I will commit it tomorrow. Current version: https://gcc.gnu.org/projects/gomp/ General suggestions about this page - like what to add, split off, move around are also welcome. (Likewise comments to Tobias PS: The patch assumes that's Sandra's intervening-code support patch is applied (should happen in a few hours). PPS: The GCC 14 release notes still need to be updated to match the current support. Alas, that's an on going theme as features keep getting added :-) ----------------- 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 projects/gomp/: Update implementation status and minor fixes diff --git a/htdocs/projects/gomp/index.html b/htdocs/projects/gomp/index.html index 2df67403..04bfd908 100644 --- a/htdocs/projects/gomp/index.html +++ b/htdocs/projects/gomp/index.html @@ -38,7 +38,9 @@ OpenMP and OpenACC are supported with GCC's C, C++ and Fortran compilers.
