From: Tom Honermann Date: Fri, 29 Nov 2019 17:43:51 +0000 (+0000) Subject: libstdc++: P1423R3 char8_t remediation (4/4) X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=cd502796cfd03b91dcc1bfeae2d9137d38ff3951;p=gcc.git libstdc++: P1423R3 char8_t remediation (4/4) New tests This patch adds new tests to validate new deleted overloads of wchar_t, char8_t, char16_t, and char32_t for ordinary and wide formatted character and string ostream inserters. Additionally, new tests are added to validate invocations of u8path with sequences of char8_t for both the C++17 and filesystem TS implementations. 2019-11-29 Tom Honermann New tests * testsuite/27_io/basic_ostream/inserters_character/char/deleted.cc: New test to validate deleted overloads of character and string inserters for narrow ostreams. * testsuite/27_io/basic_ostream/inserters_character/wchar_t/deleted.cc: New test to validate deleted overloads of character and string inserters for wide ostreams. * testsuite/27_io/filesystem/path/factory/u8path-char8_t.cc: New test to validate u8path invocations with sequences of char8_t. * testsuite/experimental/filesystem/path/factory/u8path-char8_t.cc: New test to validate u8path invocations with sequences of char8_t.
