I've missed yesterday that the if_present is on the EXEC_OMP_SCAN, not on
some outer EXEC that could be arbitrary and as !$omp scan can have only
exclusive and inclusive clauses and nothing else, we can use pretty much
all bool or unsigned :1 flags for that purpose as long as we document it,
and the testcase with if_present on some other construct probably doesn't
buy us much.
OT, perhaps we should turn those:
bool nowait, ordered, untied, mergeable;
bool inbranch, notinbranch, defaultmap, nogroup;
bool sched_simd, sched_monotonic, sched_nonmonotonic;
bool simd, threads, depend_source, order_concurrent, capture;
into unsigned nowait : 1, ordered : 1, untied : 1, mergeable : 1;
etc. to save some memory, single bit bitfields should be pretty fast.
