a8d2e5856f Do not emit "field_type" var if not needed on "maint print c-tdesc" 
While fiddling a bit with -Wunused-variable, Sergio noticed that "maint
print c-tdesc" was always generating code for the "tdesc_type
*field_type" variable, even when it wasn't used.  This is caught by GCC
when using -Wunused-variable, of course.

This patch changes the print_c_tdesc class to only output the field
declaration when we actually need it.

It shouldn't be necessary to do the same with the other variable
declarations (type_with_fields and element_type), because they are
always if they are declared.

The C files in features/ are regenerated, some declarations of
field_type are removed, as expected, while some others move to where
they are used for the first time.

gdb/ChangeLog:

	* target-descriptions.c (print_c_tdesc) <visit>: Don't output
	field_type declaration, use printf_field_type_assignment
	instead.

a994fec4f8 gdb: Add OpenRISC or1k and or1knd target support 
This patch prepares the current GDB port of the OpenRISC processor from
https://github.com/openrisc/binutils-gdb for upstream merging.

Testing has been done with a cgen sim provided in a separate patch. This
has been tested with 2 toolchains. GCC [1] 5.4.0 from the OpenRISC
project with Newlib [2] and GCC 5.4.0 with Musl [3] 1.1.4.

It supports or1knd (no delay slot target).
The default target is or1k (with delay slot).

You can change the target arch with:

(gdb) set architecture or1knd
The target architecture is assumed to be or1knd

d4a0e8b57d Split tdesc_type into multiple classes 
This patch makes tdesc_type an abstract base class and creates three
subclasses:

- tdesc_type_builtin, for builtin types
- tdesc_type_vector, for vector types
- tdesc_type_with_fields, for struct, union, flag and enum types

This allows getting rid of the union in tdesc_type and to not allow the
std::vector separately.  I tried to go further and create separate
classes for struct, union, flag and enum, but it proved too difficult.
One problem is that from the point of the of the target description
code, the types tdesc_type_* are opaque (only forward-declared).
Therefore, it doesn't know about inheritance relationship between those
classes.  This makes it impossible to make functions that accept a
pointer to a base class and pass a pointer to a derived class, for
example.  I think this patch here is a good compromise, and if somebody
wants to improve things further, the door is open.

A make_gdb_type virtual pure method is added to tdesc_type, which
replaces the current tdesc_gdb_type function.  Calling this method on a
tdesc_type returns the corresponding built gdb type.

a8142ee195 Make tdesc_reg string fields std::string 
Make the name, group and type fields of tdesc_reg std::strings.  This
way, we don't have to manually free them in ~tdesc_reg.

Doing so results in a small change in the generated tdesc.  Instead of
passing an empty string for the group parameter of tdesc_create_reg, the
two modified tdesc now pass NULL.  The end result should be the same.

2399fe6ab0 Simplify tic6x and s390x expedite registers 
Nowadays, we have six tic6x expedite registers, which are duplicated.

tic6x-c64xp-expedite = A15,PC
tic6x-c64x-expedite = A15,PC
tic6x-c62x-expedite = A15,PC
tic6x-c64xp-linux-expedite = A15,PC
tic6x-c64x-linux-expedite = A15,PC
tic6x-c62x-linux-expedite = A15,PC

in features/Makefile, we have

   echo "expedite:$(if $($*-expedite),$($*-expedite),$($(firstword $(subst -, ,$(notdir $*)))-expedite))" \
        >> $(outdir)/$*.tmp

which means for a given bar/foo-baz.xml, we'll look for either
bar/foo-baz-expedite or foo-expedite.  We can define only one generic
expedite register for all different ti6cx and s390x target descriptions.
Actually, we've done that for x86 target descriptions.

Re-run 'make GDB=/path/build/gdb all' to regenerate regformats/*.dat files,
and they are not changed.

0abe8a8992 Dynamically composite xml in reply to GDB 
GDBserver still uses pre-generated target descriptions in order to
reply to GDB's query on target description (see xml-builtin-generated.c
in GDBserver build directory).  This patch teaches GDBserver to
create XML contents according to the target descriptions rather than
using pre-generated ones.

First, change target feature c files to pass the feature xml file
name to tdesc_create_feature, so that target description in GDBserver
can record them, and create XML contents from these features in
buffer, like

  ...
  <xi:include href="$FEATURE1_XML_NAME"/>
  <xi:include href="$FEATURE2_XML_NAME"/>
  ...

and send this buffer back to GDB.

Note that this patch reuses target_desc.xmltarget a little bit, which is
to hold the XML contents dynamically generated in tdesc_get_features_xml.
However, it is not xfree'ed in ~target_desc, because we can't tell it is
from xstrdup or a literal string.  Since we don't delete target_desc,
there is no memory leak yet.  After we change all target descriptions to
the new style, target_desc.xmltarget is from xstrdup, then, we can safely
xfree it in ~target_desc.

f49ff00066 [GDBserver] Centralize tdesc for i386-linux 
tdesc_i386_XXX_linux is used in many places in linux-x86-low.c and this
patch adds a new function i386_linux_read_description to return the right

the counterpart in GDB, and the following patch will share the duplicated

ea03d0d3c3 Lazily and dynamically create i386-linux target descriptions 
Instead of using pre-generated target descriptions, this patch
changes GDB to lazily and dynamically create target descriptions
according to the target hardware capability (xcr0 in i386).
This support any combination of target features.

Some reg in target description has "regnum" attribute, so its register
number is got from the attribute value instead from sequential allocation.

  <reg name="xmm0" bitsize="128" type="vec128" regnum="32"/>

when target description is created, it should match the regnum, so this
patch adds a new field m_next_regnum to track it, if attribute number is
greater than the m_next_regnum, print the code to set register number
explicitly.

25aa13e522 Generate c for feature instead of tdesc 
This patch changes Makefile and command "maint print c-files" so
that GDB can print c files for features instead target description.
Previously, we feed GDB a target description xml file, which generate
c files including multiple features.

With this patch, in Makefile, we wrap each feature xml file, and
create a temp target description which include only one feature.
Then, adjust the target description printer for them, and print
a c function for each given feature, so that we can use these
c functions later to create target description in a flexible way.

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.

8e2141c6fb Add optional argument to command "maint prints c-tdesc" 
Nowadays, we need two steps to print c files for xml target description,
that is, 1) read xml target description in, update the current tdesc,
2) visit the current tdesc, print the c file.  It is unnecessary to
involve in current tdesc, and some validations in each gdbarch are
performed unnecessarily, which will reject some target descriptions if
they are missing some mandatory feature.

This patch adds an optional argument to "maint print c-tdesc", which
is an XML file target description, so that we can combine the two
steps above into one step, and don't have to involve in global current
tdesc.

51547df62c Add support for Intel PKRU register to GDB and GDBserver. 
This patch adds support for the registers added by the
Memory Protection Keys for Userspace (PKU aka PKEYs) feature.
Native and remote debugging are covered by this patch.

The XSAVE area is extended with a new state containing
the 32-bit wide PKRU register. The new register is added to
amd64-avx-mpx_avx512-* tdesc, thus it is renamed accordingly. Also,
respective xstate mask X86_XSTATE_AVX_MPX_AVX512_MASK is renamed to
X86_XSTATE_AVX_MPX_AVX512_PKU_MASK to reflect the new feature set
it supports.

a1fa17ee15 Add target description for avx-avx512. 
Add a dedicated target description for the feature combination
avx-avx512 as implemented by certain IA CPU models.

The corresponding X86_XSTATE_AVX_AVX512_MASK already exists, but shared
the tdesc with X86_XSTATE_AVX_MPX_AVX512_MASK. This caused MPX registers
displayed as undefined on CPUs that only implemented
X86_XSTATE_AVX_AVX512_MASK, which is undesired. This patch solves this issue.

This patch also corrects the wrong usage of x32-avx-mpx-avx512, which is
replaced by x32-avx-avx512. The MPX feature is not implemented in x32 mode.

22049425ce Rename target descriptions to reflect actual content of description. 
To better reflect the actual feature set covered by the IA target
descriptions, the existing descriptions are renamed. Each feature of
the extended state is added to the name of a description or xstate mask
starting from AVX.
For example, amd64-mpx-avx512-linux becomes amd64-avx-mpx-avx512-linux,
while amd64-avx-linux remains unchanged.
Likewise, the corresponding xstate masks are changed, e.g. from
X86_XSTATE_MPX_AVX512_MASK to X86_XSTATE_AVX_MPX_AVX512_MASK.

414c838a72 Simplify i386, amd64 and x32 expedite registers 
Nowadays, there are a lot of duplication about
i386/{i386, amd64, x32}*-expedite in features/Makefile.  However,
in features/Makefile, we have

 echo "expedite:$(if $($*-expedite),$($*-expedite),$($(firstword $(subst -, ,$(notdir $*)))-expedite))" \
	  >> $(outdir)/$*.tmp

which means for a given bar/foo-baz.xml, we'll look for either
bar/foo-baz-expedite or foo-expedite.  In x86 expedite registers, we
use the former now, but it will be much simpler if we use the latter.
This is what this patch does.  This patch removes them, and defines
three generic expedite.  Re-run 'make GDB=/path/build/gdb all' to
regenerate regformats/*.dat files, and they are not changed.

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.

6a17ca318b Regenerate some target description files 
I regenerated all target description .c files from scratch, and got
this spurious diff.

It's a simple mid-air collision - these files were clearly generated
before commit 73b4f516a0 ("maint_print_c_tdesc_cmd: Use type for
TYPE_CODE_FLAGS instead of field_type."), which did the global
s/field_type/type/, and pushed to master afterwards.

f42bf748e4 Re-factor (i386|amd64)mpx target descriptions. 
In the previous patch a new set of target descriptions
(i386|amd64)-avx-mpx were added  being same as the (i386|amd64)-mpx.
This patch removes AVX feature from  (i386|amd64)-mpx target
description set.

This way the (i386|amd64)avx_mpx(_linux|) set has AVX and MPX features
and (i386|amd64)mpx(_linux|) only MPX.
