Use INCLUDE_VECTOR before including system.h, instead of directly
including <vector>, to avoid running into poisoned identifiers.

libcc1/ChangeLog:

	PR middle-end/111632
	* libcc1plugin.cc: Fix include.
	* libcp1plugin.cc: Fix include.

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.

While working on another patch, I discovered that the libcc1 plugin
code never did version negotiation correctly.  So, the patches to
introduce v1 never did anything -- the new code, as far as I know, has
never been run.

Making version negotiation work shows that the existing code causes
crashes.  For example, safe_lookup_builtin_type might return
error_mark_node in some cases, which the callers aren't prepared to
accept.

Looking into it some more, I couldn't find any justification for this
v1 code for the C compiler plugin.  Since it's not run at all, it's
also clear that removing it doesn't cause any regressions in gdb.

However, rather than remove it, this patch changes it to handle
ERROR_MARK better, and then to fall back to the v0 code if the new
code fails to find the type it's looking for.

libcc1

	* libcc1plugin.cc (safe_lookup_builtin_type): Handle ERROR_MARK.
	(plugin_int_type): Fall back to plugin_int_type_v0.
	(plugin_float_type): Fall back to plugin_float_type_v0.

The gdb tests of the libcc1 plugin have been failing lately.  I
tracked this down to a crash trying to access an enum's underlying
type.  This patch fixes the crash by setting this type.


	* libcc1plugin.cc (plugin_build_enum_type): Set

On musl <pthread.h> uses calloc() (via <sched.h>). <memory> includes

libcc1/

	PR c++/106102
	* libcc1plugin.cc: Include <memory> via "system.h".
	* libcp1plugin.cc: Ditto.

This patch completes the transition of libcc1 from the use of separate
template functions for different arities to the use of variadic
functions.  This is how I had wanted it to work from the very
beginning, and is possible now with C++11.

I had thought that variadic callbacks required C++17, but it turns out
that the approach taken here is basically equivalent to std::apply --
just a bit wordier.

libcc1

	* rpc.hh (argument_wrapper) <get>: Replace cast operator.
	(argument_wrapper<T *>) <get>: Likewise.
	(unmarshall): Add std::tuple overloads.
	(callback): Remove.
	(class invoker): New.
	* libcp1plugin.cc (plugin_init): Update.
	* libcp1.cc (libcp1::add_callbacks): Update.
	* libcc1plugin.cc (plugin_init): Update.
	* libcc1.cc (libcc1::add_callbacks): Update.
	* connection.cc (cc1_plugin::connection::do_wait): Update.

Both plugins in libcc1 share a fair amount of boilerplate.  They both
share error-emission code, context management code, and tree GC code.
This patch unifies these two bodies of code, avoiding needless
duplication.

libcc1

	* libcc1plugin.cc: Move code to context.cc.
	* libcp1plugin.cc: Move code to context.cc.
	* context.hh: New file.
	* context.cc: New file.
	* Makefile.in: Rebuild.
	* Makefile.am (AM_CPPFLAGS): Add more gcc flags.
	(CPPFLAGS_FOR_C, CPPFLAGS_FOR_CXX): Update.
	(libcc1plugin_la_SOURCES): Add context.hh, context.cc.
	(libcp1plugin_la_SOURCES): Likewise.

This changes libcc1 to ues foreach in a couple of spots.

libcc1

	* libcp1plugin.cc (plugin_context::mark): Use foreach.
	* libcc1plugin.cc (plugin_context::mark): Use foreach.

This changes libcc1 to use std::vector in the code that builds
function types.  This avoids some explicit memory management.

libcc1

	* libcp1plugin.cc (plugin_build_function_type): Use std::vector.
	* libcc1plugin.cc (plugin_build_function_type): Use std::vector.

Now that C++11 can be used in GCC, libcc1 can be changed to use
templates and type traits to handle unmarshalling all kinds of enums.

libcc1

	* marshall.hh (cc1_plugin::unmarshall): Use type traits.
	* marshall-cp.hh (cc1_plugin::unmarshall): Remove overloads.
	* marshall-c.hh: Remove.
	* libcc1plugin.cc: Update includes.
	* libcc1.cc: Update includes.

In cleaning up C++'s handling of hidden decls, I renamed its
DECL_BUILTIN_P, which checks for loc == BUILTINS_LOCATION to
DECL_UNDECLARED_BUILTIN_P, because the location gets updated, if user
source declares the builtin, and the predicate no longer holds.  The
original name was confusing me.  (The builtin may still retain builtin
properties in the redeclaration, and other predicates can still detect
that.)

I discovered that tree.h had its own variant 'DECL_IS_BUILTIN', which
behaves in (almost) the same manner.  And therefore has the same
mutating behaviour.

This patch deletes the C++ one, and renames tree.h's to
DECL_IS_UNDECLARED_BUILTIN, to emphasize its non-constantness.  I
guess _IS_ wins over _P

The patch <https://gcc.gnu.org/ml/gcc-patches/2014-11/msg00698.html>
adding an overload for fatal_error that passes an explicit location
broke gcc.pot regeneration because xgettext cannot handle function
overloads with the diagnostic string argument in different positions.

As the desired direction is for all diagnostics to have explicit
locations, this patch addresses the regression by removing the version
of fatal_error that does not pass a location, passing explicit
input_location everywhere (in the hope that those will incrementally
be changed to other locations, much as with the addition of a location
argument to pedwarn some time ago - a lot of cases aren't meaningfully
associated with a source file so UNKNOWN_LOCATION may be better).

Note that this patch does not attempt to fix any existing issues with
these diagnostics (such as wrongly starting with capital letters or
ending with '.' or '\n'); it just adds the input_location argument.

Bootstrapped with no regressions for x86_64-unknown-linux-gnu (Go
excluded).
