x86: Replace VexW=3 with VexWIG

* i386-opc.tbl (VexWIG): New.
Replace VexW=3 with VexWIG.

python: Make gdb.execute("show commands") work (PR 23669)

Since commit

  56bcdbea2bed ("Let gdb.execute handle multi-line commands")

trying to use a command like gdb.execute("show commands") in Python
fails.  GDB ends up trying to run the "commands" command.

The reason is that GDB gets confused with the special "commands"
command.  In process_next_line, the lookup_cmd_1 function returns the
cmd_list_element representing the "commands" sub-command of "show".
Lower, we check the cmd_list_element to see if it matches various
control commands by name, including the "commands" command.  This is
where we wrongfully conclude that the executed command must be
"commands", when in reality it was "show commands".

The fix proposed in this patch removes the comparisons by name, instead
comparing the cmd_list_element object by pointer with the objects
created at initialization time.

Tested on the buildbot, though on a single builder (Fedora-x86_64-m64).

Don't steal references in the gdb Python code

Some Python APIs steal references from their caller, and the refcount
checker supports this via an attribute.

However, in gdb with C++ we have a better idiom available: we can use
std::move on a gdbpy_ref<> instead.  This makes the semantics obvious
at the point of call, and is safer at runtime as well, because the
callee's gdbpy_ref<> will be emptied.

This patch changes the reference-stealing code in gdb to use rvalue
references instead.

Tested on x86-64 Fedora 28.

Expand "show disassembler-options" output

I typed this:

x86: Set Vex=1 on VEX.128 only vmovq

AVX "VMOVQ xmm1, xmm2/m64" and "VMOVQ xmm1/m64, xmm2" can only be
encoded with VEX.128.  Set Vex=1 on VEX.128 only vmovq and update
assembler tests.

Consolidate run_dump_test

This merges the three versions of run_dump_test.  Improved warning
handling versus the old gas version shows up a number of tests that
need their disassembly updating:
arm-linuxeabi  +FAIL: ARM v1 instructions
arm-linuxeabi  +FAIL: Accepted v8-a with ARMv8.1 AdvSIMD.
arm-linuxeabi  +FAIL: bl local instructions for v4t.
arm-linuxeabi  +FAIL: UDF
and some that now fail due to detecting assembly warnings:
h8300-elf  +FAIL: binutils-all/strip-13
h8300-elf  +FAIL: binutils-all/strip-14
h8300-elf  +FAIL: binutils-all/strip-15

I've generally kept the union of all run_dump_test features, except
that the ld target aliases "cfi" and "shared" have disappeared, as has
the binutils substitution of $srcdir as $scrdir/$subdir.

binutils/

run_dump_test replace PROG with DUMPPROG in gas and ld

To be compatible with the binutils version, that uses PROG for the
tool under test and DUMPPROG for the dump tool.

source file name, like the current ld version.

gas run_dump_test rename stderr and error-output

Use warning_output and error_output, like the ld version of
run_dump_test.  Note that some tests used the wrong option, and this
went undetected since the gas version of run_dump_test doesn't
properly check tool error status.  This patch corrects wrong options,
in preparation for a later patch that will check error status.

Remove run_dump_test support for objcopy as a dump program

We have three copies of run_dump_test in the testsuite.  This is a first
step towards consolidating them.

A few tests use objcopy to convert to verilog or srec output, then
check that output is as expected.  Those tests can just as easily use
objdump, keeping the set of dump programs (addr2line, nm, objdump,
readelf, size) separate from utilities under test.  That in turn makes
auto-detecting the dump program possible in more places.

Fix possible exception leak in python.c

In the Python code, gdb exceptions may not leak into the Python core.
execute_gdb_command was calling bpstat_do_actions outside of a
TRY/CATCH; which seemed risky.  I don't have a test case for this, but
if bpstat_do_actions could ever throw, it could crash gdb.

This patch introduces a new scope in order to preserve the current
semantics, so it is looks a bit bigger than it really is.

gdb: Don't leak memory with TYPE_ALLOC / TYPE_ZALLOC

This patch started as an observation from valgrind that GDB appeared
to be loosing track of some memory associated with types.  An example
valgrind stack would be:

  24 bytes in 1 blocks are possibly lost in loss record 419 of 5,361
     at 0x4C2EA1E: calloc (vg_replace_malloc.c:711)
     by 0x623D26: xcalloc (common-utils.c:85)
     by 0x623D65: xzalloc(unsigned long) (common-utils.c:95)
     by 0x72A066: make_function_type(type*, type**) (gdbtypes.c:510)
     by 0x72A098: lookup_function_type(type*) (gdbtypes.c:521)
     by 0x73635D: gdbtypes_post_init(gdbarch*) (gdbtypes.c:5439)
     by 0x727590: gdbarch_data(gdbarch*, gdbarch_data*) (gdbarch.c:5230)
     by 0x735B99: builtin_type(gdbarch*) (gdbtypes.c:5313)
     by 0x514D95: elf_rel_plt_read(minimal_symbol_reader&, objfile*, bfd_symbol**) (elfread.c:542)
     by 0x51662F: elf_read_minimal_symbols(objfile*, int, elfinfo const*) (elfread.c:1121)
     by 0x5168A5: elf_symfile_read(objfile*, enum_flags<symfile_add_flag>) (elfread.c:1207)
     by 0x8520F5: read_symbols(objfile*, enum_flags<symfile_add_flag>) (symfile.c:794)

When we look in make_function_type we find a call to TYPE_ZALLOC
(inside the INIT_FUNC_SPECIFIC macro).  It is this call to TYPE_ZALLOC
that is allocating memory with xcalloc, that is then getting lost.

The problem is tht calling TYPE_ALLOC or TYPE_ZALLOC currently
allocates memory from either the objfile obstack or by using malloc.
The problem with this is that types are allocated either on the
objfile obstack, or on the gdbarch obstack.

As a result, if we discard a type associated with an objfile then
auxiliary data allocated with TYPE_(Z)ALLOC will be correctly
discarded.  But, if we were ever to discard a gdbarch then any
auxiliary type data would be leaked.  Right now there are very few
places in GDB where a gdbarch is ever discarded, but it shouldn't hurt
to close down these bugs as we spot them.

This commit ensures that auxiliary type data is allocated from the
same obstack as the type itself, which should reduce leaked memory.

The one problem case that I found with this change was in eval.c,
where in one place we allocate a local type structure, and then used
TYPE_ZALLOC to allocate some space for the type.  This local type is
neither object file owned, nor gdbarch owned, and so the updated
TYPE_ALLOC code is unable to find an objstack to allocate space on.

My proposed solution for this issue is that the space should be
allocated with a direct call to xzalloc.  We could extend TYPE_ALLOC
to check for type->gdbarch being null, and then fall back to a direct
call to xzalloc, however, I think that making this rare case of a
local type require special handling is not a bad thing, this serves to
highlight that clearing up the memory will require special handling
too.

This special case of a local type is interesting as the types owner
field (contained within the main_type) is completely null.  While
reflecting on this I looked at how types use the get_type_arch
function.  It seems clear that, based on how this is used, it is never
intended that null will be returned from this function.  This only
goes to reinforce, how locally alloctaed types, with no owner, are
both special, and need to be handled carefully.  To help spot errors
earlier, I added an assert into get_type_arch that the returned arch
is not null.

Inside gdbarch.c I found a few other places where auxiliary type data
was being allocated directly on the heap rather than on the types
obstack.  I have fixed these to call TYPE_ALLOC now.

Finally, it is worth noting that as we don't clean up our gdbarch
objects yet, then this will not make much of an impact on the amount
of memory reported as lost at program termination time.  Memory
allocated for auxiliary type information is still not freed, however,
it is now on the correct obstack.  If we do ever start freeing our
gdbarch structures then the associated type data will be cleaned up
correctly.

Tested on X86-64 GNU/Linux with no regressions.

PR ld/21375: MIPS: Fix non-zero run-time value for undefined weaks

We have an issue in the MIPS backend, with the handling of undefined
hidden and internal weak symbols.  References to such symbols are
supposed to resolve to 0 according to the ELF gABI[1]:

"Unresolved weak symbols have a zero value."

and the 64-bit MIPS psABI[2]:

"If a symbol with one of these [hidden or internal] attributes has no
definition within the executable/DSO being linked, then it must be
resolved to allocated space if common, resolved to zero if weak, or an
error reported otherwise."

however if a GOT relocation is used, then a local GOT entry is created
and used to satisfy the reference.  Such an entry is then (in DSO and
PIE binaries) subject to the usual load-time relocation, which means a
non-zero value will be returned if the base address is non-zero.  This
will defeat the usual run-time sequence like:

void a (void) __attribute__ ((visibility ("hidden"), weak));

void
x (void)
{
  if (a)
    a ();
}

This can be reproduced with this simple code:

$ cat libtest.c
extern int a __attribute__ ((visibility ("hidden"), weak));

int *
x (void)
{
  return &a;
}
$ cat test.c

int *x (void);

int
main (void)
{
  printf ("a: %p\n", x ());

  return 0;
}
$ gcc -shared -fPIC -o libtest.so libtest.c
$ gcc -o test test.c -Wl,-rpath,$(pwd) libtest.so
$ ./test
a: 0x77184000
$

The usual approach targets take is making all the steps required to
assign a GOT entry for the symbol referred, and then leave its contents
at zero with no dynamic relocation attached, therefore ensuring that the
value does not change at load time.  However this is not going to work
with the implicitly relocated GOT the MIPS psABI specifies[3]:

"The dynamic linker relocates the global offset table by first adding
the difference between the base where the shared object is loaded and
the value of the dynamic tag DT_MIPS_BASE_ADDRESS to all local global
offset table entries."

and we cannot therefore use the local GOT part.

And we cannot offhand use the global part either, as the symbol would
then have to be exported and possibly wrongly preempt symbols in other
modules involved in the dynamic load, because as per the ELF gABI[1] we
are not allowed to enter a hidden or internal symbol into the dynamic
symbol table (and then use its associated GOT entry):

"A hidden symbol contained in a relocatable object must be either
removed or converted to STB_LOCAL binding by the link-editor when the
relocatable object is included in an executable file or shared object."

and:

"An internal symbol contained in a relocatable object must be either
removed or converted to STB_LOCAL binding by the link-editor when the
relocatable object is included in an executable file or shared object."

So we have to choose something else.

Our choice is further limited by the need for the reference associated
with the GOT relocation to stay within the signed 16-bit limit from the
GOT pointer base register, while being compliant with the ELF gABI and
the MIPS psABI.  However as Alan Modra has observed[4] one possibility
is to edit (relax) the code such that the GOT reference is removed
altogether.

Based on these observations then modify MIPS BFD linker backend code to:

1. Interpret code associated with GOT relocations and relax the usual LW
   or LD instructions into a corresponding immediate load operation that
   places the value of 0 in the intended register, while leaving the GOT
   entry allocated and initialized as usually.

2. Leave any other instructions associated with GOT relocations in place
   and instead redirect the reference to a global GOT entry associated
   with a special `__gnu_absolute_zero' symbol created for this purpose,
   whose value is 0, SHN_ABS section marks it absolute, binding is
   global and export class protected, ensuring that the locally provided
   value is always used at load time, and that the value is not
   relocated by the dynamic loader.

3. Adjust any high-part GOT relocation used, typically associated with
   a LUI instruction, accordingly, so that run-time consistency is
   maintained, either by resolving to the original entry if the
   instruction associated with the corresponding low-part GOT relocation
   has been relaxed to an immediate load (in which case the value loaded
   with LUI will be overwritten), or by also redirecting the reference
   to `__gnu_absolute_zero' to complete the GOT access sequence if that
   symbol has been used.

4. Add a target `elf_backend_hide_symbol' hook, for the three MIPS ABIs,
   which prevents the `__gnu_absolute_zero' symbol from being forced
   local, to ensure that the redirection works and the symbol remains
   global/protected with existing linker scripts unchanged.

5. Observing the issue with handling SHN_ABS symbols in the GNU dynamic
   loader, covered by glibc PR 19818, set the EI_ABIVERSION field in the
   ELF file header produced to 4 (ABI_ABSOLUTE) if `__gnu_absolute_zero'
   symbol has been produced and the target configured indicates the GNU
   operating system, so that broken versions of the GNU dynamic loader
   gracefully reject the file in loading rather than going astray.  Keep
   EI_ABIVERSION at the original value for other operating systems or if
   no `__gnu_absolute_zero' symbol has been made.

The name of the special `__gnu_absolute_zero' has no meaning other than
how a human reader can interpret it, as it is ignored in dynamic loading
in the handling of the scenarios concerned.  This is because the symbol
resolves locally, and it's only the symbol's attributes that matter so
that the associated GOT entry remains unchanged at load time.

Therefore the name is somewhat arbitrary, observing however the need to
use the name space reserved for the system so that it does not conflict
with a possible user symbol, and hence the leading underscore, and also
the `gnu' infix to denote a GNU feature.  Other implementations wishing
to address the problem in a similar way may choose a different name and
have the solution still work, possibly with a mixture of modules used in
a dynamic having symbols of different names provided, which will however
not interact with each other due to the protected export class.

The symbol can be referred explicitly, however the name is an internal
implementation detail rather than a part of the ABI, and therefore no
specific semantics is guaranteed.

One limitation of this change is that if `__gnu_absolute_zero' has been
already defined, then we do not wipe the old definition and all kinds of
odd behavior can result.  This is however like with other symbols we
internally define, such as `_GLOBAL_OFFSET_TABLE_' or `__rld_map', and
therefore left as a possible future enhancement.

As an optimization the relaxation of LW and LD instructions to a load of
immediate zero is always made, even SVR4 PIC code for code that will end
up in a regular (non-PIE) executable, because there is a cache advantage
with the avoidance of a load from the GOT, even if it is otherwise
guaranteed to remain zero.  It does not reliably happen though, due to a
symbol exportation issue affecting executables, covered by PR ld/21805.

One existing test case needs to be updated, as it triggers relaxation
introduced with this change and consequently linker output does not
match expectations anymore.  As we want to keep the original issue
covered with the test case modify it then to use the LWL instruction in
place of LW, and adjust the output expected accordingly.

dwarf2.c code reasonably assumes that debug info is local to a file,
an assumption now violated by gcc, resulting in "DWARF error: invalid
abstract instance DIE ref" or wrong details when attempting to print
linker error messages with file, function and line reported.

This is because find_abstract_instance is only prepared to handle
DW_FORM_ref_addr when the .debug_info section referenced is in the
current file.  When that isn't the case, relocations to access another
file's .debug_info will typically be against a symbol defined at the
start of that .debug_info section, plus an addend.  Since the dwarf2.c
code only considers the current file's debug info, that symbol will be
undefined, resolving to zero.  In effect the ref_addr will wrongly
resolve to the current file's .debug_info.

This patch avoids the problem by treating relocations in debug
sections against undefined symbols in a similar manner to the way
relocations against symbols defined in discarded sections are
resolved.  They result in a zero value (except in .debug_ranges)
regardless of the addend.

Fix crash with empty Rust enum

While testing my Rust compiler patch to fix the DWARF representation
of Rust enums (https://github.com/rust-lang/rust/pull/54004), I found
a gdb crash coming from one of the Rust test cases.

The bug here is that the new variant support in gdb does not handle
the case where there are no variants in the enum.

This patch fixes the problem in a straightforward way.  Note that the
new tests are somewhat lax because I did not want to try to fully fix
this corner case for older compilers.  If you think that's
unacceptable, let meknow.

Tested on x86-64 Fedora 28 using several versions of the Rust
compiler.  I intend to push this to the 8.2 branch as well.

python: Provide textual representation for Inferior and Objfile

Printing a GDB Python object is notoriously not helpful:

>>> print(gdb.selected_inferior())
<gdb.Inferior object at 0x7fea59aed198>
>>> print(gdb.objfiles())
[<gdb.Objfile object at 0x7fea59b57c90>]

This makes printing debug traces more difficult than it should be.  This
patch provides some repr() implementation for these two types (more to
come if people agree with the idea, but I want to test the water first).
Here's the same example as above, but with this patch:

>>> print(gdb.selected_inferior())
<gdb.Inferior num=1>
>>> print(gdb.objfiles())
[<gdb.Objfile filename=/home/emaisin/build/binutils-gdb-gcc-git/gdb/test>]

I implemented repr rather than str, because when printing a list (or
another container I suppose), Python calls the repr method of the
elements.  This is useful when printing a list of inferiors or objfiles.
The print(gdb.objfiles()) above would not have worked if I had
implemented str.

I found this post useful to understand the difference between repr and
str:
