From fdc116781b03f5d30e93f5013159f39c4c0f3471 Mon Sep 17 00:00:00 2001 From: Simon Marchi Date: Mon, 9 Apr 2018 13:31:05 -0400 Subject: [PATCH] Copy string_view tests from libstdc++ This patch copies the string_view tests from the gcc repository (commit 02a4441f002c). ${gcc}/libstdc++-v3/testsuite/21_strings/basic_string_view -> ${binutils-gdb}/gdb/unittests/basic_string_view The local modifications are done in the following patch, so that it's easier to review them. gdb/ChangeLog: * unittests/basic_string_view/capacity/1.cc: New file. *
