--- Comment #11 from Jakub Jelinek <jakub at gcc dot gnu.org> --- (In reply to vries from comment #10) > Created attachment 35639 [details] > tentative patch for GOACC_data_end That is a bad idea, as void GOACC_data_end (void) is already exported out of libgomp, so this is an ABI break. If it is meant as a hack around not specifying the functions to aliasing oracle properly, and not really needed after expansion to RTL, you could e.g. use an internal function in GIMPLE and then lower it to normal function call that doesn't take the argument.
