gdb/testsuite: Avoid infinite loop in gdb.reverse/step-reverse.exp
This testcase sometimes gets stuck in a loop for hours when running in our
CI. The problem is that due to an issue unrelated to reverse debugging the
inferior exits early, and because of the overly generic ".*" pattern the
testcase keeps sending the "next" command without noticing that the
inferior is gone.
gdb_test_multiple has a pattern to detect that "The program is not being
run.", but since it is placed after the patterns from the caller it won't
be triggered. It also has a timeout pattern but because it is triggered
between successful matches, each time the test matches the '-re -wrap ".*"'
this counts as a successful match and the timeout is reset.
Since the test binary is compiled with debug information, fix by changing
one of the generic patterns to match entering the main function and the
other one to match the source code line number that is shown by GDB right
after the "step" command.
Also, as a precaution add a maximum number of times the "next" command will
be sent.

[GOLD] PowerPC64 huge branch dynamic relocs
PowerPC64 gold and ld.bfd implement an indirect branch trampoline,
used when the destination of a branch exceeds a bounce through another
"b" instruction. When generating PIEs or shared libraries, the
addresses need dynamic relocations. This was implemented in gold
using a dedicated relocation section, but this means the relative
relocations for these addresses are not sorted properly with other
dynamic relative relocations: gold doesn't support merging relocation
sections, then sorting. Instead we need to use a single .rela.dyn
section.

account for needed dynamic relocations, delaying adding the actual
relocations until the end of relaxation once the layout has

b7b77500dc5 ("[gdb/testsuite] Clean standard_output_file dir in

This caused a regression when using "make check -j 2", due to the cleanup
removing the active gdb.log, so I reverted the commit.
Try again, this time handling the two cases separately.
If the standard_output_file directory contains an active gdb.log, check that
the directory contains no files other than gdb.log and gdb.sum. This puts
the reponsibility for the cleanup at the callers in gdb/testsuite/Makefile.in
which use --outdir.
If the standard_output_file directory doesn't contain an active gdb.log, clean
it by removing the entire directory.
An exception is made for performance tests, where cleaning up the
standard_output_file dir is the wrong thing to do, because an invocation with
GDB_PERFTEST_MODE == run is intended to reuse binaries left there by an
earlier invocation with GDB_PERFTEST_MODE == compile.

gdb/DAP Few bug fixes & Evaluate Array Watch vars

EvaluateResult does not need a name, just as what Tom pointed out in
previous review. It's only the *children* that need to be made sure that
their names are valid. An identifier for a variable, can't ever have an
integer as a name, anyhow (not as far as I am aware, no programming
languages allow for that).
Removed the f-strings and use str() instead as pointed out that
f-strings might not be supported fully.

This patch fixes a few bugs.
First of all, name of VariableReferences must always be of string type.
This patch makes sure that this is the case by formatting the name. If
(when) the name is an integer, this will cause clients to fail or throw
errors.
Fixes a bug in NoOpArrayPrinter that calculated children to be N, but
only ever retrieves N-1 children, which makes Python at some time later
(during fetch_children -> fetch_one_child(N) ) raise an exception (out
of list index) which makes the entire request go bad.
The result[self.result_name] also f-strings the printer.to_string()
value, because this can potentially be a LazyString (which is a Python
object, not a string) and is not serializable by json.dumps.

[gdb/testsuite] Reimplement Term::command_no_prompt_prefix
Say we run test-case gdb.tui/basic.exp. It calls Term::enter_tui, which does:
...
command_no_prompt_prefix "tui enable"
...
The proc command_no_prompt_prefix is documented as:
...
# As proc command, but don't wait for an initial prompt. This is used for
# initial terminal commands, where there's no prompt yet.
...
Indeed, before the "tui enable" command, the tuiterm is empty, so there is no
prompt and just before switching to TUI we have in the tuiterm:
...
tui enable
...
The reason that there is no prompt, is that:
- in order for tuiterm to show something, its input processing procs need to
be called, and
- the initial gdb prompt, and subsequent prompts generated by gdb_test-style
procs, are all consumed by those procs instead.
This is in principle not a problem, but the absence of a prompt makes a
tuiterm session look less like a session on an actual xterm.
Add a new proc gen_prompt, that:
- generates a prompt using echo
- consumes the response before the prompt using gdb_expect
- consumes the prompt using Term::wait_for "".
This allows us to reimplement Term::command_no_prompt_prefix using
Term::command, and just before switching to TUI we have in the tuiterm:

Eli:
Updated docs & NEWS to reflect new changes. Added
a reference from the .ptid attribute of the ThreadExitedEvent
to the ptid attribute of InferiorThread. To do this,
I've added an anchor to that attribute.
Tom:
Tom requested that I should probably just emit the thread object;
I ran into two issues for this, which I could not resolve in this patch;
1 - The Thread Object (the python type) checks it's own validity
by doing a comparison of it's `thread_info* thread` to nullptr. This
means that any access of it's attributes may (probably, since we are
in "async" land) throw Python exceptions because the thread has been
removed from the thread object. Therefore I've decided in v3 of this
patch to just emit most of the same fields that gdb.InferiorThread has, namely
global_num, name, num and ptid (the 3-attribute tuple provided by
gdb.InferiorThread.ptid).
2 - A python user can hold a global reference to an exiting thread. Thus
in order to have a ThreadExit event that can provide attribute access
reliably (both as a global reference, but also inside the thread exit
handler, as we can never guarantee that it's executed _before_ the
thread_info pointer is removed from the gdbpy thread object),
the `thread_info *` thread pointer must not be null. However, this
comes at the cost of gdb.InferiorThread believing it is "valid" - which means,
that if a user holds takes a global reference to that
exiting event thread object, they can some time later do `t.switch()` at which
point GDB will 'explode' so to speak.
v2:
Fixed white space issues and NULL/nullptr stuff,
as requested by Tom Tromey.
v1:
Currently no event is emitted for a thread exit.
This adds this functionality by emitting a new gdb.ThreadExitedEvent.
It currently provides four attributes:
- global_num: The GDB assigned global thread number
- num: the per-inferior thread number
- name: name of the thread or none if not set
- ptid: the PTID of the thread, a 3-attribute tuple, identical to
InferiorThread.ptid attribute
Added info to docs & the NEWS file as well.
Added test to test suite.
Fixed formatting.

remote_file host delete [standard_output_file prog.o]
remote_file host delete [standard_output_file prog.ali]

Replace this with cleaning up the entire directory instead, for all
test-cases.

[gdb/testsuite] Remove f-string in gdb.python/py-unwind.py
on openSUSE Leap 42.3, with python 3.4, I run into a

gdb.python/py-unwind.py.
Fix this by using string concatenation using '+' instead.

[gdb/testsuite] Add nopie in a few test-cases
When running test-case gdb.arch/i386-disp-step.exp with target board

...
gdb compile failed, ld: i386-disp-step0.o: warning: relocation in read-only section `.text'
ld: warning: creating DT_TEXTREL in a PIE

Fix this by adding nopie in the compilation flags.

[gdb/testsuite] Clean up before compilation in gdb.ada/call-no-debug.exp
Running test-case gdb.ada/call-no-debug.exp with target board unix/-m64 works
fine, but if we run it again with target board unix-m32, we run into:
...
gnatlink prog.ali -m32 -g -o prog^M
ld: i386:x86-64 architecture of input file `b~prog.o' is incompatible with \
i386 output^M
...
This is due to compiling with no-force.
The test-case:
- first compiles pck.adb into pck.o (without debug info), and
- then compiles prog.adb and pck.o into prog (with debug info).
Using no-force in the second compilation make sure that pck.adb is not
compiled again, with debug info.
But it also means it will pick up intermediate files related to prog.adb from
a previous compilation.
Fix this by removing prog.o and prog.ali before compilation.

0f2cd53cf4f ("[gdb/testsuite] Handle missing .note.GNU-stack") I

but failed to do so for gdb.arch/thumb*.S. Fix this oversight.

LoongArch: Fix ld "undefined reference" error with --enable-shared
Because _bfd_read_unsigned_leb128 is hidden visibility, so it can't
be referenced out of shared object.
The new function loongarch_get_uleb128_length just used to call
_bfd_read_unsigned_leb128.

x86: shrink Masking insn attribute to a single bit (boolean)
The logic can actually be expressed with less code that way, utilizing
that there are common patterns of when which form of masking is
permitted. This then also eliminates the large set of open-codings of
BOTH_MASKING in the opcode table.

Correct ld-elf/eh5 test for hppa64
Commit
3c0afdb78988 regressed this test for hppa64, because the test
had been enabled for hppa64 in the time between the mips changes and
their reversion. This patch isn't just a simple reapply, I recreated
the testsuite change by hand for hppa64: Two lines in eh5.d might need
further changes for mips.
