Fix PR libcc1/113977
PR libcc1/113977 points out a case where a simple expression is
rejected with a compiler error message. The bug here is that gdb does
not inform the plugin of the correct alignment -- in fact, there is no
way to do that.
This patch adds a new method to allow the alignment to be set, and
bumps the C front end protocol version.
It also includes some updates to various comments in 'include', done
here to simplify the merge to binutils-gdb.
include
* gcc-cp-interface.h (gcc_cp_fe_context_function): Update
comment.
* gcc-c-interface.h (enum gcc_c_api_version) <GCC_C_FE_VERSION_2>:
New constant.
(gcc_c_fe_context_function): Update comment.
* gcc-c-fe.def (finish_record_with_alignment): New method.
Update documentation.
libcc1
PR libcc1/113977
* libcc1plugin.cc (plugin_finish_record_or_union): New function.
(plugin_finish_record_or_union): Rewrite.
(plugin_init): Use GCC_C_FE_VERSION_2.
* libcc1.cc (c_vtable): Use GCC_C_FE_VERSION_2.
(gcc_c_fe_context): Check for GCC_C_FE_VERSION_2.
