--- Comment #8 from Tobias Burnus <burnus at gcc dot gnu.org> --- > If you are asking for a new OpenMP feature, this is not the right forum, > GCC bugzilla is for reporting bugs. While I want to echo what Jakub wrote, I have nonetheless filed the OpenMP specification issue #4539 about this issue. (Unfortunately, OpenMP's specification issues are not publicly visible.) [Like always with issue tracking and specification work, it is unclear when it will be addressed and in which way it will be addressed.] [Adding improved mapper support came actually up at the OpenMP BoF at ISC-HPC last week - and the committee members are aware that there is room for improvement. However, when it is unclear how to best solve an issue, it tends to getting deferred; on the other hand, new or stalled issues can also be suddenly picked up and get quickly resolved.] Regarding 'declare mapper' in GCC 16: There are some known issues and some pending patches have to be still applied (with some issues fixed before doing so). Thus, take the current implementation with a pinch of salt.
