In addition to adding ll_caches and numa_domain abstract names to OMP_PLACES syntax, OpenMP 5.1 also added one syntax simplification: https://github.com/OpenMP/spec/issues/2080 https://github.com/OpenMP/spec/pull/2081 in particular that in the grammar place non-terminal is now not only { res-list } but also res (i.e. a non-negative integer), which stands as a shortcut for { res } So, one can specify OMP_PLACES=0,4,8,12 with the meaning OMP_PLACES={0},{4},{8},{12} or OMP_PLACES=0:4 instead of OMP_PLACES={0}:4 or OMP_PLACES={0},{1},{2},{3} etc. This patch implements that. 2021-10-15 Jakub Jelinek <jakub@redhat.com> * env.c (parse_one_place): Handle non-negative-number the same as { non-negative-number }. Reject even !number:1 and !number:1:stride or !place:1 or !place:1:stride instead of just length other than 1. * libgomp.texi (OpenMP 5.1): Document OMP_PLACES syntax extensions and OMP_NUM_TEAMS/OMP_TEAMS_THREAD_LIMIT and omp_{set_num,get_max}_teams/omp_{s,g}et_teams_thread_limit features as implemented. * testsuite/libgomp.c/affinity-1.c: Add a test for the 5.1 place simplified syntax.

The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*.
