Any comments before I commit the following patch updating the webpage?
OpenACC: Add the init/set/shutdown directive support for Fortran to https://gcc.gnu.org/gcc-17/changes.html (→ OpenACC, section added here) For OpenMP, I noticed a while ago parsing 'device_type' for variables is supported since GCC 10 (Fortran: 11), i.e. half a year before OpenMP 5.1 was even released. Looking at the code, it does not seem to be really handled besides parsing - but testing shows that it largely is, possibly the linker fixes this mostly - such that the symbol is only in host/nohost. Still, only marked as 'partial' - for now. → https://gcc.gnu.org/projects/gomp/ (→ Impl. Status → 5.1). * * * Thomas Schwinge wrote:
From: Sebastian Galindo This patch adds parsing and libgomp runtime calls for these directives, sharing the existing implementation with runtime API calls. It also includes support for the device_type and device_num clauses in the Fortran front-end.
Cool! Side remark: routine, parallel, kernels, and loop also support the device_type clause since OpenACC 2.5; eventually, support for this has to be added as well. [Later versions seem to add it for 'serial' + 'data' as well.] - Just for completeness. [And I just noticed: "The device_type clause may be abbreviated to dtype", this seems to be simple to implement for C/C++/Fortran and seems to be not implemented in GCC.] * * * Tobias PS: I hope the release notes + status are now up to date. There is more, but I think those fall under prep work or bug fixes.
