Jakub Jelinek	f89163fd48	re PR libgomp/58691 (OpenMP 4: Surprising results with OMP_PLACES=) ... PR libgomp/58691 * config/linux/proc.c (gomp_cpuset_popcount): Add unused attribute to check variable. (gomp_init_num_threads): Move i variable declaration into #ifdef CPU_ALLOC_SIZE block. * config/linux/affinity.c (gomp_affinity_init_level): Test gomp_places_list_len == 0 rather than gomp_places_list == 0 when checking for topology reading error. * team.c (gomp_team_start): Don't handle bind == omp_proc_bind_false. * env.c (parse_affinity): Add ignore argument, if true, don't populate gomp_places_list, only parse env var and always return false. (parse_places_var): Likewise. Don't check gomp_global_icv.bind_var. (initialize_env): Always parse OMP_PLACES and GOMP_CPU_AFFINITY env vars, default to OMP_PROC_BIND=true if OMP_PROC_BIND wasn't specified and either of these variables were parsed correctly into a places list.
