6eb1e6a8c1 Use visitor pattern for "maint print c-tdesc"
Target description can be modeled as a tree, the target description
is the root node, features are children nodes, registers and types are
grand-children nodes.  So command "maint print c-tdesc" in effect
traverse/visit each node, and print them in c.  This can be
implemented by visitor pattern, this is the first reason.  Secondly,
I want to this command prints c files in a different way for some
specific xml files, but still print c files the same way for the rest
of xml files.  Third, I even want to print xml files from target
descriptions, so that GDBserver can use it to reply GDB's query
qXfer:features:read:target.xml.

ee8da4b839 Make "end" field in feature specs required again.
Newer gdbservers may be talking to older gdbs,
and older gdbs will flag a missing "end" as an error.
So just make "end" required again, and for compatibility
change the default field type to "bool".

2016-10-06  Doug Evans  <dje@google.com>

	* features/aarch64-core.xml (cpsr_flags): Elide "type" and specify
	"end" in all fields.
	* features/aarch64.c: Regenerate.
	* features/i386/32bit-mpx.xml (_bndcfgu): Specify type of "preserved"
	and "enabled" fields. Correct size of "enabled" field.
	* features/i386/64bit-mpx.xml (_bndcfgu): Specify type of "preserved"
	and "enabled" fields.
	* features/i386/i386-avx-mpx-linux.c: Regenerate.

	* features/arc-v2.c: Regenerate.
	* xml-tdesc.c (tdesc_start_field): Require "end" spec.  Single bit
	fields default to "bool" type.

ad0a504f7e arc: New Synopsys ARC port
ARC is a family of licensable processors developed by Synopsys.

This is an initial patch that doesn't yet support some of the features, that
are already available in Synopsys' fork of GDB, namely:

  * longjmp support
  * signal frame handling
  * prologue analysis
  * Linux targets support
  * native Linux support

ARC cores are configurable and extensible, which means from debugger
perspective that some registers and debug capabilities are optional, therefore
it is up to the GDB stub to determine exact list of register available on
target and supply it to GDB via XML target descriptions.  List of registers
that is known to GDB and is required is intentionally kept small to simplify
requirements to GDB stub and implementation of a GDB client.

gdb/ChangeLog:

	* Makefile.in (ALL_TARGET_OBS): Add arc-tdep.o.
	(HFILES_NO_SRCDIR): Add arc-tdep.h.
	(ALLDEPFILES): Add arc-tdep.c.
	* NEWS: Mention new ARC port.
	* configure.tgt: Add ARC.
	* arc-tdep.c: New file.
	* arc-tdep.h: New file.
	* features/Makefile (XMLTOC): Add arc-v2.xml and arc-arcompact.xml.
	* features/arc-v2.xml: New file.
	* features/arc-v2.c: New file (generated).
	* features/arc-arcompact.xml: New file.
	* features/arc-arcompact.c: New file (generated).

gdb/doc/ChangeLog:

	* gdb.texinfo (Embedded Processors): Document ARC.
	(Synopsys ARC): New section.
	(Standard Target Features): Document ARC features.
	(ARC Features): New section.

gdb/testsuite/ChangeLog:

	* gdb.xml/tdesc-regs.exp: set core-regs for arc*-*-elf32.
