Add a C++ wrapper for GCC C plug-in This patch introduces a new class which wraps the GCC C compile plug-in. It is a little unfortunate that this all happened in between the time that GCC moved to C++ and GDB moved to C++, leaving us with an ABI promise to support a C-like interface. The hope is to isolate GDB from some of this should it change in the future. Broadly, what this does is replace calls like: C_CTX (context)->c_ops->operation (C_CTX (context), ...); with calls that now look like: context->c_plugin->operation (...); This API will be further refined in following patches when struct compile_instance/compile_c_instance are changed into classes. gdb/ChangeLog: * Makefile.in (HFILES_NO_SRCDIR): Add compile/gcc-c-plugin.h. * compile/compile-c-types.c: Define GCC_METHODN macros and include gcc-c-fe.def to define C plugin. (delete_instance): Delete `c_plugin'. (new_compile_instance): Initialize `c_plugin'. * compile/compile-c.h: Include gcc_c_plugin.h. (struct compile_c_instance) <c_plugin>: New member. * gcc-c-plugin.h: New file. Update all callers with API change.

/* GCC C plug-in wrapper for GDB.
Update copyright year range in all GDB files. This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files.
