The previous patch copied the string_view tests from libstdc++. This patch adjusts them in a similar way that the libstdc++ optional tests are integrated in our unit test suite. Not all tests are used, some of them require language features not present in c++11. For example, we can't use a string_view constructor where the length is not explicit in a constexpr, because std::char_traits::length is not a constexpr itself (it is in c++17 though). Nevertheless, a good number of tests are integrated, which covers pretty well the string_view features. gdb/ChangeLog: * Makefile.in (SUBDIR_UNITTESTS_SRCS): Add string_view-selftests.c. * unittests/basic_string_view/capacity/1.cc: Adapt to GDB testsuite. * unittests/basic_string_view/cons/char/1.cc: Likewise. * unittests/basic_string_view/cons/char/2.cc: Likewise. * unittests/basic_string_view/cons/char/3.cc: Likewise. * unittests/basic_string_view/element_access/char/1.cc: Likewise. * unittests/basic_string_view/element_access/char/empty.cc: Likewise. * unittests/basic_string_view/element_access/char/front_back.cc: Likewise. * unittests/basic_string_view/inserters/char/2.cc: Likewise. * unittests/basic_string_view/modifiers/remove_prefix/char/1.cc: Likewise. * unittests/basic_string_view/modifiers/remove_suffix/char/1.cc: Likewise. * unittests/basic_string_view/modifiers/swap/char/1.cc: Likewise. * unittests/basic_string_view/operations/compare/char/1.cc: Likewise. * unittests/basic_string_view/operations/compare/char/13650.cc: Likewise. * unittests/basic_string_view/operations/copy/char/1.cc: Likewise. * unittests/basic_string_view/operations/data/char/1.cc: Likewise. * unittests/basic_string_view/operations/find/char/1.cc: Likewise. * unittests/basic_string_view/operations/find/char/2.cc: Likewise. * unittests/basic_string_view/operations/find/char/3.cc: Likewise. * unittests/basic_string_view/operations/find/char/4.cc: Likewise. * unittests/basic_string_view/operations/rfind/char/1.cc: Likewise. * unittests/basic_string_view/operations/rfind/char/2.cc: Likewise. * unittests/basic_string_view/operations/rfind/char/3.cc: Likewise. * unittests/basic_string_view/operations/substr/char/1.cc: Likewise. * unittests/basic_string_view/operators/char/2.cc: Likewise. * unittests/string_view-selftests.c: New file.
