Subject: Fix experimental::pmr typedefs and add tests
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b8eac4d06438eb3dfe3c7d88b4b5b16ee0f9816b;p=gcc.git

Fix experimental::pmr typedefs and add tests

The typedefs in <experimental/regex> and <experimental/string> don't
need to be in the __cxx11 namespace, because they are only aliases and
so will have the same mangled name as the underlying types.

	* include/experimental/regex: Remove begin/end macros for namespace.
	* include/experimental/string: Likewise.
	* testsuite/experimental/polymorphic_allocator/pmr_typedefs_deque.cc:
	New test.
	* testsuite/experimental/polymorphic_allocator/
	pmr_typedefs_forward_list.cc: New test.
	* testsuite/experimental/polymorphic_allocator/pmr_typedefs_list.cc:
	New test.
	* testsuite/experimental/polymorphic_allocator/pmr_typedefs_map.cc:
	New test.
	* testsuite/experimental/polymorphic_allocator/pmr_typedefs_match.cc:
	New test.
	* testsuite/experimental/polymorphic_allocator/
	pmr_typedefs_multimap.cc: New test.
	* testsuite/experimental/polymorphic_allocator/
	pmr_typedefs_multiset.cc: New test.
	* testsuite/experimental/polymorphic_allocator/pmr_typedefs_set.cc:
	New test.
	* testsuite/experimental/polymorphic_allocator/pmr_typedefs_string.cc:

	* testsuite/experimental/polymorphic_allocator/
	pmr_typedefs_unordered_map.cc: New test.
	* testsuite/experimental/polymorphic_allocator/
	pmr_typedefs_unordered_multimap.cc: New test.
