PR remote/19496, timeout in forking-threads-plus-bkpt

This patch addresses a failure in
gdb.threads/forking-threads-plus-breakpoint.exp:

FAIL: gdb.threads/forking-threads-plus-breakpoint.exp: cond_bp_target=1:
detach_on_fork=on: inferior 1 exited (timeout)

Cause:

A fork event was reported to GDB before GDB knew about the parent
thread, followed immediately by a breakpoint event in a different
thread.  The parent thread was subsequently added via
remote_notice_new_inferior in process_stop_reply, but when the thread
was added the thread_info.state was set to THREAD_STOPPED.  The fork
event was then handled correctly, but when the fork parent was resumed
via a call to keep_going, the state was unchanged.

The breakpoint event was then handled, which caused all the
non-breakpoint threads to be stopped.  When the breakpoint thread was
resumed, all the non-breakpoint threads were resumed via
infrun.c:restart_threads.  Our old fork parent wasn't restarted,
because it still had thread_info.state set to THREAD_STOPPED.
Ultimately the program under debug hung waiting for a pthread_join
while the old fork parent was stopped forever by GDB.

Fix:

Since this is non-stop, then the bug is that the thread should have
been added in THREAD_RUNNING state.  Consider that infrun may be
pulling target events out of the target_ops backend into its own event
queue, but, not process them immediately.  E.g., infrun may be
stopping all threads temporarily for a step-over-breakpoint operation
for thread A (stop_all_threads).  The waitstatus of all threads is
thus left pending in the thread structure (save_status), including the
fork event of thread B.  Right at this point, if the user does "info
threads", that should show thread B (the fork parent) running, not
stopped, even if internally, gdb is holding it paused for a little
bit.

Thus if in non-stop mode, always add new threads in the external
user-visible THREAD_RUNNING state.  Change remote_notice_new_inferior
to accept the internal executing state of the thread instead, with
EXECUTING set to 1 when we discover a thread that is running on the
target (such as through remote_update_thread_list), and 0 when the
thread is really paused (such as when we see a stop reply).

Tested on x86_64 Linux and Nios II Linux target with x86 Linux host.

linux-record: Simplify with record_mem_at_reg()

The function record_linux_system_call() often records a memory area
whose address is contained in a register.  So far this required two
function calls: one for fetching the register value, and another one for
recording the memory area.  These two function calls are now merged into
a new local helper function, and all occurrences are adjusted.  This
reduces the source code and makes it more readable.

PR remote/19496, interrupted syscall in forking-threads-plus-bkpt

This patch addresses "fork:Interrupted system call" (or wait:) failures
in gdb.threads/forking-threads-plus-breakpoint.exp.

The test program spawns ten threads, each of which do ten fork/waitpid
sequences.  The cause of the problem was that when one of the fork
children exited before the corresponding fork parent could initiate its
waitpid for that child, a SIGCHLD and/or SIGSTOP was delivered and
interrupted a fork or waitpid in another thread.

The fix was to wrap the system calls in a loop to retry the call if
it was interrupted, like:

do
  {
    pid = fork ();
  }
while (pid == -1 && errno == EINTR);

Since this is a Linux-only test I figure it is OK to use errno and EINTR.
I tried a number of alternative fixes using SIG_IGN, SA_RESTART,
pthread_sigblock, and bsd_signal, but none of these worked as well.

Tested on Nios II Linux target with x86 Linux host.

PR 18303, Tolerate malformed input for lookup_symbol-called functions

lookup_symbol is often called with user input.  Consequently, any
function called from lookup_symbol{,_in_language} should attempt to
deal with malformed input gracefully.  After all, malformed user
input is not a programming/API error.

This patch does not attempt to find/correct all instances of this.  It
only fixes locations in the code that trigger test suite failures.

This patch fixes PR breakpoints/18303, "Assertion: -breakpoint-insert
with windows paths of file in non-current directory".

The patch includes three new tests related to this.  One is just
gdb.linespec/ls-errs.exp copied and converted to use C++ instead of C, and
to add a case using a file name containing a Windows-style logical drive
specifier.  The others include an MI test to provide a regression test for
the specific case reported in PR 18303, and a C++ test for proper error
handling of access to a program variable when using a file scope specifier
that refers to a non-existent file.

fallback to using it.

S390: Add use of unavailable-stack frame ID

When determining the frame ID of an inline frame, GDB currently asserts
that a valid ID of the underlying real frame is found, and that it does
not match outer_frame_id.  From inline_frame_this_id():

  /* For now, require we don't match outer_frame_id either (see
     comment above).  */
  gdb_assert (!frame_id_eq (*this_id, outer_frame_id));

However, this assertion may fail when the real frame's unwinder can not
determine the frame ID.  This happened on an s390x target with a binary
that lacked call frame information and also confused the prologue
analyzer, because then s390_frame_this_id() left the frame ID at its
default.

To fix this, this change enhances s390_frame_this_id such that an

8 years agoAvoid spaces in osabi names
Pedro Alves [Wed, 9 Mar 2016 15:52:43 +0000 (15:52 +0000)]
Avoid spaces in osabi names

It's not possible today to select some of the osabis by name.
Specifically, those that have spaces in their names and then the first
word is ambiguous...

For example:
 (gdb) set osabi <TAB>
 [...]
 FreeBSD ELF
 FreeBSD a.out
 [...]
 (gdb) set osabi FreeBSD ELF
 Ambiguous item "FreeBSD ELF".

In reality, because "set osabi" is an enum command, that was
equivalent to trying "set osabi FreeBSD", which is then obviously
ambiguous, because of "FreeBSD ELF" and "FreeBSD a.out".

Also, even if the first word is not ambiguous, we actually ignore
whatever comes after the first word:

 (gdb) set osabi GNU/Linux
 (gdb) show osabi
 The current OS ABI is "GNU/Linux".
 The default OS ABI is "GNU/Linux".
 (gdb) set osabi Windows SomeNonsense
                         ^^^^^^^^^^^^
 (gdb) show osabi
 The current OS ABI is "Windows CE".
 The default OS ABI is "GNU/Linux".
 (gdb)

Fix this by avoiding spaces in osabi names.

We could instead make "set osabi" have a custom set hook, or
alternatively make the enum set hook (in cli-setshow.c) handle values
with spaces, but OTOH, I have a feeling that could cause trouble.
E.g., in cases where we might want to write more than one enum value
in the same line.  We could support quoting as workaround, but, not
sure we want that.  "No spaces" seems like a simpler rule.

Fix v850 bfd arch info printable names

Currently, it's not possible to manually set some of the v850 archs in
gdb:

 (gdb) set architecture v850<TAB>
 v850 (using old gcc ABI)
 v850-rh850
 v850e
 v850e (using old gcc ABI)
 v850e1
 [...]
 (gdb) set architecture v850 (using old gcc ABI)
 Ambiguous item "v850 (using old gcc ABI)".

The problem is that "set architecture" is a GDB "enum command", and
GDB only considers an enum value to be the string up until the first
space.  So writing "v850 (using old gcc ABI)" is the same as writing
"v850", and then that's not an unambiguous arch printable name prefix.

v850 is actually the only arch that has spaces in its printable name.
One can conveniently see that with e.g.:

 (gdb) set max-completions unlimited
 (gdb) complete set architecture
 ...

Rather than hack GDB into accepting this somehow, make v850 arch
printable names more like the printable names of the other archs, and
put the abi variant in the "machine" part, after a ':'.

We now get:

 (gdb) set architecture v850<TAB>
 v850:old-gcc-abi
 v850:rh850
 v850e
 v850e1
 v850e1:old-gcc-abi
 v850e2
 v850e2:old-gcc-abi
 [...]

And now "set architecture v850:old-gcc-abi" works as expected.

I ran the binutils/gas/ld testsuites, and found no regressions.  I
don't have a cross compiler handy, but I ran the gdb tests anyway,
which covers at least some snoke testing.

I think that the OUTPUT_ARCH in ld/scripttempl/v850.sc may have got
broken with the previous 2012 change, since I hacked v850_rh850.sc to
output "v850" and ld failed to grok it.  I think it only works if the
old GCC ABI is the configured v850 default ABI.  That's now fixed by
changing to use explicit v850:old-gcc-abi.

Also, this actually "fixes" an existing GDB test, which isn't likewise
expecting spaces in arch names, when GDB is configured for
--target=v850:
