With the multi-target work, each inferior will have its own target
stack, so to call a target method, we'll need to make sure that the
inferior in question is the current one, otherwise target->beneath()
calls will find the target beneath in the wrong inferior.
In some places, it's much more convenient to be able to check whether
an inferior has execution without having to switch to it in order to
call target_has_execution on the right inferior/target stack, to avoid
side effects with switching inferior/thread/program space.
The current target_ops::has_execution method takes a ptid_t as
parameter, which, in a multi-target world, isn't sufficient to
identify the target. This patch prepares to address that, by changing
the parameter to an inferior pointer instead. From the inferior,
we'll be able to query its target stack to tell which target is
beneath.
Also adds a new inferior::has_execution() method to make callers a bit
more natural to read.

The "set remote exec-file" setting is per-inferior, but the "show
remote exec-file" command always shows the last set exec-file,
irrespective of the current inferior. E.g.:
# Set inferior 1's exec-file:
(gdb) set remote exec-file prog1
# Add inferior 2, switch to it, and set its exec-file:
(gdb) add-inferior
Added inferior 2
(gdb) inferior 2
(gdb) set remote exec-file prog2
# Switch back to inferior 1, and show its exec-file:
(gdb) inferior 1
(gdb) show remote exec-file
prog2

The multi-target patch sets inferior_ptid to null_ptid before handling
a target event, and thus before calling target_wait, in order to catch
places in target_ops::wait implementations that are incorrectly
relying on inferior_ptid (which could otherwise be a ptid of a
different target, for example). That caught this instance in
record-full.c.
Fix it by saving the last resumed ptid, and then using it in
record_full_wait_1, just like how the last "step" argument passed to
record_full_target::resume is handled too.
gdb/ChangeLog:
2020-01-10 Pedro Alves <palves@redhat.com>
* record-full.c (record_full_resume_ptid): New global.
(record_full_target::resume): Set it.
(record_full_wait_1): Use record_full_resume_ptid instead of
inferior_ptid.
In non-stop mode, if you resume the program in the background (with
"continue&", for example), then gdb makes sure to not switch the
current thread behind your back. That means that you can be sure that
the commands you type apply to the thread you selected, even if some
other thread that was running in the background hits some event just
while you're typing.
In all-stop mode, however, if you resume the program in the
background, gdb let's the current thread switch behind your back.
This is bogus, of course. All-stop and non-stop background
resumptions should behave the same.
This patch fixes that, and adds a testcase that exposes the bad
behavior in current master.
The fork-running-state.exp changes are necessary because that
preexisting testcase was expecting the old behavior:
Before:
continue &
Continuing.
(gdb)
[Attaching after process 8199 fork to child process 8203]
[New inferior 2 (process 8203)]
info threads
Id Target Id Frame
1.1 process 8199 "fork-running-st" (running)
* 2.1 process 8203 "fork-running-st" (running)
(gdb)
After:

Continuing.
(gdb)

* 1.1 process 24660 "fork-running-st" (running)
2.1 process 24664 "fork-running-st" (running)
(gdb)
Here we see that before this patch GDB switches current inferior to
the new inferior behind the user's back, as a side effect of handling
the fork.
The delete_exited_threads call in inferior_appeared is there to fix an
issue that Baris found in a previous version of this patch. The
fetch_inferior_event change increases the refcount of the current
thread, and in case the fetched inferior event denotes a thread exit,
the thread will not be deleted right away. A non-deleted but exited
thread stays in the inferior's thread list. This, in turn, causes the
"init_thread_list" call in inferior.c to be skipped. A consequence is
that the global thread ID counter is not restarted if the current
thread exits, and then the inferior is restarted:
(gdb) start

According to the SystemTap documentation on user-space probes[0], stap
probe points without semaphores are denoted by setting the semaphore
address in the probe's note to zero. At present the code does do a
comparison of the semaphore address against zero, but only after it's
been relocated; as such it will (almost?) always fail, commonly
resulting in GDB trying to overwrite the ELF magic located at the
image's base address.
This commit tests the address as specified in the SDT note rather than
the relocated value in order to correctly detect absent probe
semaphores.

This patch resolves a couple of issues with the test case for SystemTap
user-space probe points:
1. The preprocessor macro guarding the semaphore variables in the C
file is (rather confusingly) named USE_PROBES. This has been
renamed to USE_SEMAPHORES, to better reflect its function.
2. The test procedures in the expect file improperly pass the flag
defining USE_PROBES to prepare_for_testing; as such, the test
binary that's supposed to have probes with semaphores is the same
as the one without. This has also been fixed.
3. No test is performed to check that `info probes' returns
information about probe semaphores. Such a test is included in this
patch.

With static PIE linking undefined weak symbols are resolved to 0, so no

This changes the fix to PR 25210 by removing the ELF class change.
As it turns out the correct change was only the change in compress.c.
Everything else is unneeded and setting the elf class is making the linker
behave very oddly under LTO. The first stub is correctly written out but for
the rest the suddenly don't have a pointer to the stub section anymore.
This caused SPEC to fail as the program would branch to the stub and it wouldn't
be filled in.

Until recently when the source window was scrolled the assembler
window would scroll in sync - keeping the disassembly for the current
line in view.
This was broken in commit:
commit b4b49dcbff
Date: Wed Nov 13 16:47:58 2019 -0700
Don't call tui_show_source from tui_ui_out
This commit restores the synchronised scrolling and also maintains the
horizontal scroll within the source view when it is vertically
scrolled, something that was broken before.
This commit does not mean that scrolling the assembler view scrolls
the source view. The connection this way never existed, though maybe
it should, but I'll leave adding this feature for a separate commit.

Hannes Domani pointed out that my previous patch to fix the "list"
command in the TUI instead broke vertical scrolling. While looking at
this, I found that do_scroll_vertical calls print_source_lines, which
seems like a very roundabout way to change the source window. This
patch removes this oddity and fixes the bug at the same time.
I've added a new test case. This is somewhat tricky, because the
obvious approach of sending a dummy command after the scroll did not
work -- due to how the TUI works, sennding a command causes the scroll
to take effect.

Currently if a user starts the tui with 'layout asm' then they will be
presented with the 'src' layout.
What happens is:
1. Layout command enables TUI, selecting the SRC layout by default.
2. As part of tui_enable we call tui_display_main, which calls
tui_get_begin_asm_address, which calls
set_default_source_symtab_and_line. This changes core GDBs
current symtab and line, which triggers a call to the symtab
changed hook tui_symtab_changed, which sets the flag
from_source_symtab.
3. Back in the layout command, the layout is changed from SRC to
ASM. After this the layout command completes and we return to
core GDB which prints the prompt, however...
4. The before prompt hook is called which sees the
from_source_symtab flag is set and forces the SRC window to be
displayed. This switches us back to SRC view.
The solution I propose here is to delay installing the hooks into core
GDB until after we have finished setting up the tui and selecting the
default frame to view. In this way we effectively ignore the first
symtab changed event triggered when making main the default symtab.

The Term::dump_screen routine currently dumps the screen using calls
to 'verbose', this means it will only dump the screen when the
testsuite is running in verbose mode.
However, the Term::dump_screen is most often called when a test fails,
in this case I think it is useful to have the screen dumped even when
we're not in verbose mode.
This commit changes the calls to 'verbose' to be 'verbose -log' so we
always get the screen dump.

In this commit:
commit 5024637fac
Date: Sun Dec 15 11:05:47 2019 +0100
Fix skip.exp test failure observed with gcc-9.2.0
A race condition was introduced into the gdb.base/skip.exp test when
this line:
gdb_test "step" "foo \\(\\) at.*" "step 3"
Was changed to this:
gdb_test "step" "foo \\(\\) at.*" "step 3" "main \\(\\) at .*" "step"
Before the above change we expected GDB to behave like this:
(gdb) step
foo () at /path/to/gdb/testsuite/gdb.base/skip.c:42
42 return 0;
(gdb)
However, when the test is compiled with GCC 9.2.0 we get a different
behaviour, and so we need a second 'step', like this:
(gdb) step
main () at /path/to/gdb.base/skip.c:32
32 x = baz ((bar (), foo ()));
(gdb) step
foo () at /path/to/gdb/testsuite/gdb.base/skip.c:42
42 return 0;
(gdb)
Now the change to the test matches against 'main () at .*', however if
GDB or expect is being slow then we might only get to see output like
this:
(gdb) step
main () at /path/to/g
This will happily match the question pattern, so we send 'step' to GDB
again. Now GDB continues to produce output which expect accepts, we
now see this:
b.base/skip.c:32
32 x = baz ((bar (), foo ()));
(gdb)
This has carried on from where the previous block of output left off.
This doesn't match the final pattern 'foo \\(\\) at.*', but it does
match the prompt pattern that gdb_test_multiple adds, and so we report
the test as failing.
The solution is to simply ensure that the question consumes everything
up to, and including the prompt. This ensures that the prompt can't
then match the failure case. The new test line becomes:
gdb_test "step" "foo \\(\\) at.*" "step 3" \
"main \\(\\) at .*\r\n$gdb_prompt " "step"

Checking just the base opcode without also checking this isn't a VEX
encoding, and without there being other insn properties avoiding a match
once respective VEX/XOP/EXEX-encoded insns would appear, is at least
dangerous. Add respective checks. At the same time there's no real need
to check the extension opcode to be None for the 0xA8 form - there's
nothing it can be confused with, and non-VEX-and-alike forms also can't
appear.
Commit ac0ab1842d ("i386: Also check R12-R15 registers when optimizing
testq to testb") didn't go quite far enough: In order to avoid confusing
other code registers would better be converted to byte ones uniformly.
The disassembler change is such that in default mode we'd disassemble
the insns (for there not ebing any conflicts), but when AMD64 mode was
explicitly requested, we'd show them as "(bad)".

The fix is the additional ARRAY_SIZE test, the rest just tidies
variable types rather than adding a cast to avoid warnings.

PR build/24937 concerns an error given by the clang provided by a
particular version of macOS. In particular, it reports
error: default initialization of an object of const type 'const
stap_static_probe_ops' without a user-provided default constructor
Although (at least according to sources I found online) this was
resolved as a bug in the standard, it seemed simple enough to work
around this.
Given that this is a trivial build fix, I think it should go on the
gdb 9 branch as well.

Cygwin meets the expectations of gdb for styling (if TERM is set and not
'DUMB', the terminal supports 'ANSI' (ECMA-48) escape sequences.

* cli/cli-style.c: Set cli_styling to 'true' in the Cygwin build.
We use gas' expression function to parse the operands of an
instruction in a generic way. There are situations when we have labels
and registers having the same name as well as the substraction sign
doesn't always stands for the arithmetical operation but for the
register range (e.g. enter instruction). This patch improves parsing
symbols found in a instruction operand, cleans up code and avoids
using default or undefined variables.
