2020-07-10Fix spurious unhandled remote %Stop notificationsPedro Alves2-1/+23
In non-stop mode, remote targets mark an async event source whose callback is supposed to result in calling remote_target::wait_ns to either process the event queue, or acknowledge an incoming %Stop notification. The callback in question is remote_async_inferior_event_handler, where we call inferior_event_handler, to end up in fetch_inferior_event -> target_wait -> remote_target::wait -> remote_target::wait_ns. A problem here however is that when debugging multiple targets, fetch_inferior_event can pull events out of any target picked at random, for event fairness. This means that when remote_async_inferior_event_handler returns, remote_target::wait may have not been called at all, and thus pending notifications may have not been acked. Because async event sources auto-clear, when remote_async_inferior_event_handler returns the async event handler is no longer marked, so the event loop won't automatically call remote_async_inferior_event_handler again to try to process the pending remote notifications/queue. The result is that stop events may end up not processed, e.g., "interrupt -a" seemingly not managing to stop all threads. Fix this by making remote_async_inferior_event_handler mark the event handler again before returning, if necessary. Maybe a better fix would be to make async event handlers not auto-clear themselves, make that the responsibility of the callback, so that the event loop would keep calling the callback automatically. Or, we could try making so that fetch_inferior_event would optionally handle events only for the target that it got passed down via parameter. However, I don't think now just before branching is the time to try to do any such change. gdb/ChangeLog: PR gdb/26199 * remote.c (remote_target::open_1): Pass remote target pointer as data to create_async_event_handler. (remote_async_inferior_event_handler): Mark async event handler before returning if the remote target still has either pending events or unacknowledged notifications.

2020-07-09Don't compare the pid returned from 'wait' against inferior_ptid.John Baldwin2-1/+6
'inf_ptrace::wait' needs to discard termination events reported by detached child processes. Previously it compared the returned pid against the pid in inferior_ptid to determine if a termination event should be discarded or reported. The multi-target changes cleared inferior_ptid to null_ptid in 'wait' target methods, so this was always failing and never reporting exit events. Instead, report termination events whose pid matches any inferior belonging to the current target. Several tests started failing on FreeBSD after the multi-target changes and pass again after this change. gdb/ChangeLog: * inf-ptrace.c (inf_ptrace_target::wait): Don't compare against inferior_ptid.

2020-07-09pr18841 tests on powerpc64Alan Modra2-9/+14
The PR18841 test does cross-module calls from within an ifunc resolver, which is nasty, and not supported in general since the called function may not be relocated. In this case the called function (zoo) is just a stub so doesn't need relocating, but on ppc64 the function descriptor for zoo in the executable won't be relocated at the time the shared library ifunc resolver runs. That means the test will fail if your compiler generates PIEs by default. PR 18841 * testsuite/ld-ifunc/ifunc.exp: Run pr18841 tests non-pie.

2020-07-08Use read_memory in ada_exception_message_1Tom Tromey5-3/+17
Testing using the internal AdaCore test suite showed a regression from the target string reading changes. In particular, now ada_exception_message_1 can get the wrong answer in some cases. In particular, when an Ada exception catchpoint is hit, sometimes the exception name will be incorrect. The case I was seeing changed from the correct: Catchpoint 2, CONSTRAINT_ERROR (catch C_E) at [...] to: Catchpoint 2, CONSTRAINT_ERROR (catch C_EE) at [...] I was not able to reproduce this failure with the Fedora gnat. Perhaps it is related to some local change to gnat; I do not know. Meanwhile, because ada_exception_message_1 knows the length of the string to read, we can use read_memory here. This fixes the bug. I've updated the test suite to at least exercise this code path. However, as mentioned above, the new test does not actually provoke the failure. gdb/ChangeLog 2020-07-08 Tom Tromey <tromey@adacore.com> * ada-lang.c (ada_exception_message_1): Use read_memory. gdb/testsuite/ChangeLog 2020-07-08 Tom Tromey <tromey@adacore.com> * gdb.ada/catch_ex/foo.adb: Pass string to raise. * gdb.ada/catch_ex.exp: Examine catchpoint text.

2020-07-08x86: various XOP insns lack L and/or W bit decodingJan Beulich2-123/+630
While some insns support both XOP.W based operand swapping and 256-bit operation (XOP.L=1), many others don't support one or both.

2020-07-07XCOFF ld segfaults when running ld testsuiteAlan Modra2-7/+30
The binutils XCOFF support doesn't handle random linker scripts very well at all. These tweaks to final_link fix segfaults when some linker created sections are discarded due to "/DISCARD/ : { *(.*) }" in scripts. The xcoff_mark change is necessary to not segfault on symbols defined in scripts, which may be bfd_link_hash_defined yet have u.def.section set to bfd_und_section_ptr. (Which might seem odd, but occurs during early stages of linking before input sections are mapped.) * xcofflink.c (xcoff_mark): Don't mark const sections. (bfd_xcoff_record_link_assignment): Add FIXME. (_bfd_xcoff_bfd_final_link): Don't segfault on assorted magic sections being discarded by linker script.
2020-07-07XCOFF deterministic archivesAlan Modra2-0/+20

2020-07-07XCOFF C_HIDEXT and C_AIX_WEAKEXT classificationAlan Modra2-0/+15
If C_HIDEXT and C_AIX_WEAKEXT symbols aren't handled as globals by coff_classify_symbol then we run into "warning: .. local symbol `some garbage name' has no section". These are of course both global symbols, but C_HIDEXT is like a local in some respects and returning COFF_SYMBOL_LOCAL for C_HIDEXT keeps nm output looking the same. Fixes these fails on rs6000-aix5.1: -FAIL: weakref tests, relocations -FAIL: weakref tests, global syms -FAIL: weakref tests, strong undefined syms -FAIL: weakref tests, weak undefined syms * coffcode.h (coff_classify_symbol): Handle C_HIDEXT and C_AIX_WEAKEXT.
