	x86_64: adapt MiG generated stubs to use mach_port_name_inlined_t for inlined port rights.
	For i686, we just change the code to use mach_port_name_inlined_t when
	defining the types. This is a no-op.

	For x86_64, there's a few things that are different:
	- In the server code, the server handler can get inlined ports and the
	  array will be resized and cast as an array of mach_port_name_t. Output
	  parameters have a similar treatment where the inlined array in the
	  output is used as an array of mach_port_name_t but resized to look like
	  a mach_port_name_inlined_t.
	- In the user side, we follow the same approach. Input ports as arrays
	  of mach_port_name_t are expanded into an array of mach_port_name_inlined_t.
	  Output ports are then converted back into an array of
	  mach_port_name_inlined_t so that they fit into the expected message
	  format.

	Essentially, regardless of whether port rights are inline or out of
	line, user interfaces and server stubs always receive an array of port
	rights, not mach_port_name_inlined_t. However, inlined port rights will
	be exchanged using mach_port_name_inlined_t.

	Update code generation to handle the new 64 bit ABI
	Mostly, we don't set the fields that do not exist and avoid type
	mismatching (like casting unsigned short to unsigned char for
	msgt_name).

	We also revamp type checking to compare mach_msg_type_t to uint64_t
	instead of just uint32_t as we now use the whole structure.

	Remove error procedure directives
	Back in the wonderful old days of Mach 2, when there were no send-once
	rights, dead names, or port reference counts, MIG used to have more
	kinds of operations: there were functions, procedures, simpleprocedures,
	routines, and simpleroutines. Routines returned an error code as their C
	function return value, functions had real return values, procedures and
	simpleprocedures returned void.

	Functions, procedures, and simpleprocedures signalled errors by invoking
	a global function. By default, a function named MsgError was invoked,
	but a subsystem could specify a different function using the 'error'
	directive:

	error CustomErrorHandler;

	In Mach 3, functions, procedures, and simpleprocedures are gone.
	Routines and simpleroutines are the only remaining kinds of operations.
	Some 26 years later, most of the code for generating functions,
	procedures, and simpleprocedures was removed from GNU MIG in commit
	7f10b4ed6a557b7a1fd1083939156a3dcf8b377e. Error directives remained,
	seemingly due to an oversight. So remove them too.

	Found while trying to use the word 'error' as an identifier and
	receiving a cryptic syntax error from MIG.

	Check that msgt_name is always smaller than 255.
	For the x86_64 ABI we want this to always fit into 1 byte. Even for

	Change complex_align_of to be sizeof(uintptr_t)
	By using uintptr_t, we ensure that all 64 bit stubs are free of
	undefined behavior since we support up to 8-byte alignment. This works
	fine given that Mig will type check types that have higher alignment
	requirements through the use of _Static_assert.

	This even works for a 64 bit kernel / 32 bit user land since we can use
	mig64 to build stubs for the 8-byte aligned kernel stubs and existing 32
	bit mig to build the old user side stubs. Pragma is no longer required as we take
	advantage of the compiler to drive the alignment and avoid undefined
	behavior.

	Drop -undef -ansi from cpp flags
	Since GNU Mach commit d30481122a5d24ad6b921062f93b9172ef922fc3,
	i386/machine_types.defs defines types based on defined(__x86_64__).
	Supressing the built-in macro definitions will now result in the wrong
	type being silently selected.

	-undef was initially introduced in commit
	78b6a7665db7b2eae367e17102821cbdca231d19 without much of an explanation.
	-ansi was introduced in commit 6940fb91859e46b2e96a331a029f2dc2a0ee51c9
	"to avoid -Di386=1 and the like".

	Since glibc has been using MIG with CPP set to a custom GCC invocation
	which did *not* use either flag, it appears that everything works well
	enough even without them. On the other hand, not having __x86_64__
	defined most definetely causes issues for anything that does not set a
	custom CPP when invoking MIG (i.e., most users). Other built-in
	definitions could be used in the future in a similar way (e.g. on other
	architectures); it's really more of a coincidence that they have not
	been used until now, and things kept working with -undef.

	fix message fields alignment for 64 bit

	For simplicity we keep the same 4-byte alignment as used on

	and also it seems not worth as an optimization, as we would need to

	add separate port_size and mach_port_name_size definitions
	* cpu.sym: retrieve size of vm_offset_t and mach_port_name_t from
	  gnumach headers at compile type.
	* global.{c,h}: add port size as a variable and initialize it to the
	  port name size.
	* lexxer.l: apply port or port name size to the corresponding types,
	  instead of using the word size.
	* parser.y: update port size if we're generating for kernel-space
	  (server or client). Also re-initialize default port types to account
	  for this change.
	* type.c: use port size instead of word size in default port types and
	  runtime checks.

	There are many assumptions about mach_port_t:
	 - on kernel side, its size is the same as a pointer. This allows to
	   replace the port name with the address of the corresponding data
	   structure during copyin in mach_msg()
	 - in mig, this is also the "word size", which is derived from gnumach
	   headers as the size of integer_t
	 - its size is also the same as natural_t, so it's possible to model
	   structures like mach_port_status_t as an array of integer_t in
	   mig. This is convenient since arrays and structures can't have
	   mixed types.
	 - its size is always the same as the port name size

	This patch does not change the current behaviour on 32-bit kernels,
	but allows for some of these assumptions to be broken on 64-bit
	kernels. This is needed to have 32-bit port names on 64-bit kernels
	and be able to support a 32-bit userspace.  It still leaves the choice
	for a 64-bit userspace, if all integer_t and natural_t are to be
	extended to 64 bit.

	However keeping 32-bit port names seems to be the right thing, based on
	previous discussions [1], even for a 64-bit kernel.

	The only assumption kept is that in kernel-space ports are always the
	size of a pointer, as they refer to a data structure and not to a
	specific port name.  To ensure this is true for various user/kernel
	combinations, we dynamically change the port size if we're generating
	code for kernel-space server or clients, and keep the size of a port the
	same of a port name for user-space servers and clients.

	Do not generate code dereferencing type-punned pointers
	For variable-length arrays, up to 2048 bytes are transmitted inline.
	If the array is larger, the data is transmitted out-of-line, and a
	pointer to a vm_allocated region is stored at the beginning of the
	array.

	Previously, the generated code casted the field.  Use a union instead.

	This fixes the gcc warning `dereferencing type-punned pointer will
	break strict-aliasing rules [-Wstrict-aliasing]'.

	* global.c (OOLPostfix): New variable.

	* server.c (WriteDefaultRoutine): New function.
	(WriteRoutine): Call WriteDefaultRoutine.

2014-10-10  Justus Winter  <4winter@informatik.uni-hamburg.de>

	Add support for protected payloads
	Add support for protected payloads. The new `intranpayload' option can
	be used to specify a translation function translating payloads to
	values of the translated type.  This function will be used instead of
	the `intran' function to to look up the receiving object of a message
	in a server.

	This makes it easy to use the protected payloads introduced in GNU
	Mach 1.5.

	An inTransPayload function translates payloads to objects, like an
	inTrans function translates from port names to objects.  Generate code
	in the server routine to optimize lookups to the receiver of the
	message.

	Additionally, if no intran function is provided, but an intranpayload
	function is, it is expected to translate from payloads to port names.
	This is used to preserve the semantics in case the server routine
	expects a port name.

	* NEWS: Add item.
	* lexxer.l: Emit syInTranPayload.
	* parser.h: Define syInTranPayload.
	* parser.y (TransTypeSpec): Handle syInTranPayload.
	* type.h (struct ipc_type): Add itInTransPayload.
	* server.c (WriteExtractArgValue): If a payload-aware intrans function
	has been specified, use it to get a reference to the receiving object.
	* routine.c (rtAugmentArgKind): Force the use of a local variable if a
	payload-aware translate-in function is defined.

	Update NEWS file

2014-02-21  Justus Winter  <4winter@informatik.uni-hamburg.de>

	Fix variable-sized c strings
	Previously, the terminating zero of variable-sized c strings was only
	included when copying the message if the length of the string was not
	a multiple of four.  mig_strncpy returns the length of the string
	excluding the terminating zero.  Fix this by properly accounting for
	the byte for the terminating zero in the array length.

	* server.c (WritePackArgValue): Account for the terminating zero in
	the array length.
	* user.c (WritePackArgValue): Likewise.

	* server.c (WriteSubsystemServerRoutine): New function.
	(WriteEpilog): Adjust accordingly.
	* write.h (WriteSubsystemServerRoutine): New declaration.

	Clean up generated sources
	* Makefile (CLEANFILES): Add generated source files lexxer.c and parser.c.

Fri Nov 25 13:56:32 MST 1994  Bryan Ford  (baford@cs.utah.edu)

	Merged in diffs from UK02p6 to UK02p7:

	* MIG now compiles under BSD without 'vm_???_t' types
	  conflicting between host (BSD) and target (Mach)
	  header files.  Basically, the MIG source files compiled
	  to run on the host machine no longer include mach/message.h;
	  instead they get the needed defines through cpu.h
	  which is built by compiling cpu.sym for the target machine.

Mon Aug 29 18:31:21 1994  Bryan Ford  (baford@cs.utah.edu)

	* got rid of /usr/bin pathname in call to basename:

	we get one of the send errors that can cause the message to be
	partially sent and then destroyed; otherwise we might later get a
