Sometimes waiting a bit leads to better code … Tobias Burnus wrote: ... [I guess, we eventually want to add support for more builtins. For instance, acc_on_device would be a candidate, but I could imagine some additional builtins.] I have now implemented acc_on_device and I think the new fix

[Patch] Fortran/OpenMP: Fix __builtin_omp_is_initial_device

Patches gfc_conv_procedure_call (+ called functions). Found via OpenMP_VV which uses rather pointlessly 'if (omp_is_initial_device() .eqv. .true.)' – instead of using 'if (omp_…())'. This failed with an ICE as the middle end did not like 'if ( == )' comparisons. The initial idea was to crea
