MIPS: Fix the encoding of immediates with microMIPS JALX

The microMIPS JALX instruction shares the R_MICROMIPS_26_S1 relocation
with microMIPS J/JAL/JALS instructions, however unlike the latters its
encoded immediate argument is unusually shifted left by 2 rather than 1
in calculating the value used for the operation requested.

We already handle this exception in `mips_elf_calculate_relocation' in
LD, in a scenario where JALX is produced as a result of relaxing JAL for
the purpose of making a cross-mode jump.  We also get it right in the
disassembler in `decode_micromips_operand'.

What we don't correctly do however is processing microMIPS JALX produced
by GAS from an assembly source, where a non-zero constant argument or a
symbol reference with a non-zero in-place addend has been used.  In this
case the same calculation is made as for microMIPS J/JAL/JALS, causing
the wrong encoding to be produced by GAS on making an object file, and
then again by LD in the final link.  The latter in particular causes the
calculation, where the addend fits in the relocatable field, to produce
different final addresses for the same source code depending on whether
REL or RELA relocations are used.

Correct these issues by special-casing microMIPS JALX in the places that
have been previously missed.

gas/arc: Fix array overrun when checking opcode array

The opcode array iterator mechanism can, in some situations, result in
reading memory outside of the opcode array.  When using the
iterator-next mechanism to find the next possible arc_opcode, if we find
an opcode where the name field is NULL, or the name does not match, then
the cached opcode pointer is not set to NULL.  The result is that
another call to iterator-next will again increment the opcode
pointer (which might now point outside the opcode array) and attempt to
access the name field of this undefined opcode.

Fixed in this commit by clearing the cached opcode pointer.

I've added a test case, which currently shows the bug, however, this
will only expose this bug while the opcode used (dsp_fp_cmp) is the last
opcode in the table.

Add a new test for PR 20039.  The test spawns new threads, then tries to

commit 5fe966540d6b748f825774868463003700f0c878 in master, but gdb 7.11
is affected (so if you try it on the gdb-7.11-branch right now, the test
will fail).

New in v2, the test now handles mi-async on mode properly.  The failure
was specific to mi-async off, but I don't think it's bad to test the
same thing under async on mode.  I added a little hack when running in
async mode to work around bug 20045.

I also removed one continue/interrupt pair, as a single one was enough to
trigger the problem.

Fix double prompt output after run control MI commands with mi-async on (PR 20045)

When you use a run control command (-exec-run, -exec-continue,
-exec-next, ...) with mi-async on, an extra (gdb) prompt is displayed:

  -exec-continue
  ^running
  *running,thread-id="all"
  (gdb)
  (gdb)

It doesn't seem to be a big problem for front-ends, since this behavior
started in gdb 7.9 and we haven't heard anything about that.  However,
it caused me some trouble while writing a test for PR 20039 [1].

The problem comes from an extra (gdb) prompt that we write when running
in mi-async off mode to emulate a past buggy behavior.  When executing a
run control command synchronously, previous gdbs always printed a prompt
right away, even though they are not ready to accept new MI commands
until the target stops.  Only at this time should they display a prompt.
But to keep backwards compatibility apparently, we print it anyway.
Since commit 198297aaf, the condition that decides whether we should
print that "bogus" prompt or not has become true, even when running with
mi-async on.  Since we already print a prompt at the end of the
asynchronous command execution, it results in two prompts for one
command.

The proposed fix is to call target_can_async_p instead of
target_is_async_p, to make the condition:

  if (!target_can_async_p () || sync_execution)
    ... show prompt ...

That shows the prompt if we are emulating a synchronous command on top
of an asynchronous target (sync_execution) or if the target simply can't
run asynchronously (!target_can_async_p ()).

Note that this code is changed and this bug fixed by Pedro's separate
console series, but I think it would be nice to have it fixed in the
mean time.

I ran the gdb.mi directory of the testsuite with mi-async on and off, I
didn't see any regressions.

gdb/ChangeLog:

* mi/mi-main.c (mi_on_resume): Call target_can_async_p instead
of target_is_async_p.

MIPS/opcodes: Correct mixed MIPS16 and microMIPS disassembly

Mixing MIPS16 and microMIPS code in a single binary isn't usually
supported but GAS happily produces such code if requested.  However it
is not correctly disassembled even if a symbol table is available and
function symbols are correctly anotated with the ISA mode.  This is
because the ELF-header global microMIPS ASE flag takes precedence over
MIPS16 function annotation, causing them to be treated as regular MIPS
code.

of the ELF-header flag.

Fix -exec-run not running asynchronously with mi-async on (PR gdb/18077)

When doing -exec-run on a freshly started GDB, the only target on the
target stack at the time the dummy one.  When mi_async_p is called to
know whether the run should be async, it queries whether the current
target (dummy) supports async, and the answer is no.  The fix is to make
the code query the target that will be used for the run, which is not
necessarily the current target.

No regressions in the gdb.mi directory using the unix, native-gdbserver
and native-extended-gdbserver boards.  The test doesn't pass when
forcing maint set target-async off, obviously, since it makes mi-async
have no effect.  It doesn't seem like other tests are checking for that
eventuality, so I didn't in the new test.

gdb/ChangeLog:

* mi/mi-main.c (run_one_inferior): Use run target to determine
whether to run async or not.

Add self-test framework to gdb

I wanted to unit test the Rust lexer, so I added a simple unit testing
command to gdb.

The intent is that self tests will only be compiled into gdb in
development mode.  In release mode they simply won't exist.  So, this
exposes $development to C code as GDB_SELF_TEST.

In development mode, test functions are registered with the self test
module.  A test function is just a function that does some checks, and
throws an exception on failure.

Then this adds a new "maint selftest" command which invokes the test
functions, and a new dejagnu test case that invokes it.

Match shell_prompt # in batch-preserve-term-settings.exp

batch-preserve-term-settings.exp fails if the shell prompt isn't $.  It
is # in our testing env.  In fact, the shell prompt can be anything.

The perfect solution would be "set_board_info shell_prompt" in the
host board file, and use board_info shell_prompt in
batch-preserve-term-settings.exp.  This is a little bit overkill to
me, and we still need to figure out the different prompts on different
shells.  I also tried to start shell with the prompt preset, but there is
not unique way to set shell prompt in different shells, so I give up.

It is reasonably simple to match either $ or # for the shell prompt, and
we can easily extend it to match other char, like >.

gdb/testsuite:

extending the call to `_bfd_elf_copy_private_bfd_data' with

(stub_hash_newfunc): Initialize source_value field amd remove
initialization for target_addend.

arm_stub_a8_veneer_b_cond specific code in it.  Remove
stub_entry->target_addend from points_to computation.
(cortex_a8_erratum_scan): Store in a8_erratum_fix structure the offset
to target symbol from start of section rather than the offset from the
stub address.
(elf32_arm_size_stubs): Set stub_entry's source_value and target_value
fields from struct a8_erratum_fix's offset and target_offset
respectively.
(make_branch_to_a8_stub): Rename target variable to loc.  Compute
veneered_insn_loc and loc using stub_entry's source_value.
