2019-05-04 François Dumont <fdumont@gcc.gnu.org> * include/bits/hashtable.h (_Hashtable<>::rehash): Review comment. * include/bits/hashtable_policy.h (_Prime_rehash_policy::_M_bkt_for_elements): Use __builtin_ceill. (_Power2_rehash_policy::_M_bkt_for_elements): Likewise. (_Power2_rehash_policy::_M_next_bkt): Enforce returning a result not smaller than input value rather than always greater. Preserve _M_next_resize if called with 0 input. Use __builtin_floorl. (_Power2_rehash_policy::_M_need_rehash): Rehash only if number of elements + number of insertions is greater than _M_next_resize. Start with 11 buckets if not told otherwise. Use __builtin_floorl. (_Rehash_base<>::reserve): Use rehash policy _M_bkt_for_elements. * src/c++11/hashtable_c++0x.cc (_Prime_rehash_policy::_M_next_bkt): Preserve _M_next_resize if called with 0 input. Use __builtin_floorl. (_Prime_rehash_policy::_M_need_rehash): Start with 11 buckets if not told otherwise. Use __builtin_floorl. * testsuite/23_containers/unordered_set/hash_policy/71181.cc: Adapt test to also validate _Power2_rehash_policy. * testsuite/23_containers/unordered_set/hash_policy/power2_rehash.cc: Adapt.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. 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*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
