--- Comment #21 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Author: jakub Date: Mon Oct 7 11:39:39 2013 New Revision: 203243 URL: http://gcc.gnu.org/viewcvs?rev=203243&root=gcc&view=rev Log: PR libgomp/58642 * config/linux/proc.c: Include errno.h. (gomp_get_cpuset_size): New variable. (gomp_cpuset_popcount): Add cpusetsize argument, use it instead of gomp_cpuset_size. (gomp_init_num_threads): If CPU_ALLOC_SIZE is defined and pthread_getaffinity_np returned EINVAL, increase gomp_cpuset_size and retry. After successful pthread_getaffinity_np copy gomp_cpuset_size to gomp_get_cpuset_size and try to find out minimum gomp_cpuset_size that covers all the CPUs set in gomp_cpusetp. (get_num_procs): Pass gomp_get_cpuset_size rather than gomp_cpuset_size to pthread_getaffinity_np, adjust gomp_cpuset_popcount caller. * config/linux/proc.h (gomp_cpuset_popcount): Add cpusetsize argument. * config/linux/affinity.c (gomp_affinity_finalize_place_list, gomp_affinity_init_level): Adjust gomp_cpuset_popcount callers. * testsuite/libgomp.c/affinity-1.c (pthread_getaffinity_np): Set contig_cpucount from the first successful pthread_getaffinity_np call, rather than just first call.
