GDB has a function named "current_inferior" and gdbserver has a global
variable named "current_inferior", but the two are not equivalent;
indeed, gdbserver does not have any real equivalent of what GDB calls
an inferior. What gdbserver's "current_inferior" is actually pointing
to is a structure describing the current thread. This commit renames
current_inferior as current_thread in gdbserver to clarify this. It
also renames the function "set_desired_inferior" to "set_desired_thread"
and renames various local variables from foo_inferior to foo_thread.

This adds a test that makes sure GDB knows whether the target has
continuable, or non-continuable watchpoints.
That is, the test confirms that GDB presents a watchpoint value change
at the first instruction right after the instruction that changes
memory.

In the recent review to my patch about copying files to remote host,
we find that we need a board file which is more closely mapped real
remote host testing to improve coverage. With the board file
local-remote-host-native.exp, DejaGNU copies files to
$build/gdb/testsuite/remote-host to emulate the effect of remote host.
Is it OK?

Refactor each relaxation pattern to raise the maintainability.
In origin, all patterns is analysed in nds32_elf_relax_section,
so it is hard to debug and maintain. Therefore, we classify all
patterns into different functions in this patch.
Moreover, we adjust all optimizations into nds32_elf_relax_section
to take these optimizations in turn. This can promise all relaxation
being done after calling gld${EMULATION_NAME}_after_allocation.
|
|
First, add nds32 audio ISA extension including opcodes and registers.
Second, redesign the disassemble implement.
The original disassemble decode instruction opcode using switch-case.
It is hard to synchronize when adding new instructions.
Therefore, the new implement reuses nds32_opcodes to dump the instructions.

The test does a backtrace to see which thread (#2 or #3) is assigned
to which SIGUSR (1 or 2). If the main thread gets to all_threads_running
before the sigusr threads get to their entry point, then the function
name isn't in the backtrace and the test fails.
Alas this version of the code is within epsilon of what I started with,
and then over-simplified things.

If I want to change the signalled state of multiple threads
it's a bit cumbersome to do with the "signal" command.
What you really want is a way to set the signal state of the
desired threads and then just do "continue".
This patch adds a new command, queue-signal, to accomplish this.
Basically "signal N" == "queue-signal N" + "continue".
That's not precisely true in that "signal" can be used to inject
any signal, including signals set to "nopass"; whereas "queue-signal"
just queues the signal as if the thread stopped because of it.
"nopass" handling is done when the thread is resumed which
"queue-signal" doesn't do.
One could add extra complexity to allow queue-signal to be used to
deliver "nopass" signals like the "signal" command. I have no current
need for it so in the interests of incremental complexity, I have
left such support out and just have the code flag an error if one
tries to queue a nopass signal.

I had occasion to use with_gdb_prompt in a test for the patch for PR 17314
and was passing the plain text prompt as the value, "(top-gdb)",
instead of a regexp, "\(top-gdb\)" (expressed as "\\(top-gdb\\)" in TCL).
I then discovered that in order to restore the prompt gdb passes the
original value of $gdb_prompt to "set prompt", which works because
"set prompt \(gdb\) " is equivalent to "set prompt (gdb) ".
Perhaps I'm being overly cautious but this feels a bit subtle,
but at any rate as an API choice I'd much rather pass the plain text
form to with_gdb_prompt.
I also discovered that the initial value of gdb_prompt is set in
two places to two different values.
At the global level gdb.exp sets it to "\[(\]gdb\[)\]"
and default_gdb_init sets it to "\\(gdb\\)".
The former form is undesirable as an argument to "set prompt",
but it's not clear to me that just deleting this code won't break
anything. Thus I just changed the value to be consistent and added
a comment.
gdb/testsuite/ChangeLog:
* lib/gdb.exp (gdb_prompt): Add comment and change initial value to
be consistent with what default_gdb_init uses.

The IRIX support wants to set a breakpoint to be hit when the startup
phase is complete, which is where shared libraries have been mapped
in. AFAIU, for most IRIX ports, that location is the entry point.
For MIPS IRIX however, GDB needs to set a breakpoint earlier, in
__dbx_link, as explained by:
#ifdef SYS_syssgi
/* On mips-irix, we need to stop the inferior early enough during
the startup phase in order to be able to load the shared library
symbols and insert the breakpoints that are located in these shared
libraries. Stopping at the program entry point is not good enough
because the -init code is executed before the execution reaches
that point.
So what we need to do is to insert a breakpoint in the runtime
loader (rld), more precisely in __dbx_link(). This procedure is
called by rld once all shared libraries have been mapped, but before
the -init code is executed. Unfortuantely, this is not straightforward,
as rld is not part of the executable we are running, and thus we need
the inferior to run until rld itself has been mapped in memory.
For this, we trace all syssgi() syscall exit events. Each time
we detect such an event, we iterate over each text memory maps,
get its associated fd, and scan the symbol table for __dbx_link().
When found, we know that rld has been mapped, and that we can insert
the breakpoint at the symbol address. Once the dbx_link() breakpoint
has been inserted, the syssgi() notifications are no longer necessary,
so they should be canceled. */
proc_trace_syscalls_1 (pi, SYS_syssgi, PR_SYSEXIT, FLAG_SET, 0);
#endif
The loop in irix_solib_create_inferior_hook then runs until whichever
breakpoint is hit first, the one set by solib-irix.c or the one set by
procfs.c.
Note the comment in disable_break talks about __dbx_init, but I think
that's a typo for __dbx_link:
- /* Note that it is possible that we have stopped at a location that
- is different from the location where we inserted our breakpoint.
- On mips-irix, we can actually land in __dbx_init(), so we should
- not check the PC against our breakpoint address here. See procfs.c
- for more details. */
This looks very much like referring to the loop in
irix_solib_create_inferior_hook stopping at __dbx_link instead of at
the entry point.
What this patch does is convert these deprecated raw breakpoints to
standard solib_event breakpoints. When the first solib-event
breakpoint is hit, we delete all solib-event breakpoints. We do that
in the so_ops->handle_event hook.
This allows getting rid of the loop in irix_solib_create_inferior_hook
completely, which should allow properly handling signals and other
events in the early startup phase, like in SVR4.
Built on x86_64 Fedora 20 with --enable-targets=all (builds
solib-irix.c).
Joel tested that with an earlier version of this patch "info shared"
after starting a program gave the same list of shared libraries as
before.

This patch fixes two related problems:
- By default gas is supposed to bump the current architecture
(starting with v6) as it finds "higher" instructions as the
assembling progresses. There are four possible cases depending on
the usage of the -A and -bump options:
(a) No -A and -bump are specified. In this case max_architecture
must be the highest architecture not conflicting with the
default architecture. The default opcode architecture is
indirectly set in configure.tgt and is "v9" in sparc64 systems
(from "v9-64"). Thus the maximum architecture in sparc64
systems must be "v9b". No warnings are echoed when the assembly
of an instruction bumps the current architecture.
(b) Only -bump is specified. This is like (a) but warnings are
always issued when the assembly of an instruction bumps the
current architecture.
(c) Only -A is specified. In this case bumping to a new
architecture is an error.
(d) Both -A and -bump are specified. In this case max_architecture
must be the highest architecture not conflicting with the
default architecture, but warnings are only to be issued when
bumping to an architecture higher than the architecture selected
in the -A option.
`max_architecture' is a global variable defined in tc-sparc.c which
is initialized to the opcode architecture corresponding to the
default architecture ("sparclite" for sparc-* targets and "v9" for
sparc64-* targets). Then in `md_begin' it is set to the highest
non-conflicting architecture, but only when both -A and -bump are
specified.
Thus (a) does not work:
$ echo "fzero %f0" | as
{standard input}: Assembler messages:
{standard input}:1: Error: Architecture mismatch on "fzero".
{standard input}:1: (Requires v9a|v9b; requested architecture is v9.)
Neither (b):
$ echo "fzero %f0" | as -bump
{standard input}: Assembler messages:
{standard input}:1: Error: Architecture mismatch on "fzero".
{standard input}:1: (Requires v9a|v9b; requested architecture is v9.)
Only (d) does:
$ echo "fzero %f0" | as -Av9 -bump
{standard input}: Assembler messages:
{standard input}:1: Warning: architecture bumped from "v6" to "v9a" on "fzero"
This patch fixes that function to "upgrade" `max_architecture' also
in the (a) and (b) cases.
Note that this problem becomes apparent only in sparc64-* targets
because in sparc-* targets the default architecture is the "higher"
among the 32bit architectures ("sparclite").
- Gas maintains a set of hardware capabilities associated with each
gas architecture, in `sparc_arch_table'. On the other hand
libopcodes maintains a set of hardware capabilities needed by each
individual sparc instruction.
When an instruction is assembled in `sparc_ip' gas checks for the
presence of the hardware capabilities required by the instruction,
emitting an error if some capability is missing.
However, this mechanism does not work properly if the current
architecture is bumped due to an instruction requiring new hw
capabilities not present on either the default architecture or an
architecture specified with -A:
$ echo "fzero %f0" | as -bump
{standard input}: Assembler messages:
{standard input}:1: Warning: architecture bumped from "v6" to "v9a" on "fzero"
{standard input}:1: Error: Hardware capability "vis" not enabled for "fzero".
This patch fixes this by adding the set of required hw caps of an
instruction if it triggers an architecture bump.
The patch has been tested in sparc64-unknown-linux-gnu.

The problem is that rs6000_frame_cache attempts to read the stack backchain via
read_memory_unsigned_integer, which throws an exception if the stack pointer is
invalid. With this patch, it calls safe_read_memory_integer instead, which
doesn't throw an exception and allows for safe handling of that situation.

I have started seeing occasional runaway 'attach' processes these days.
I cannot be certain it is really caused by this patch, for example
grep 'FAIL.*cmdline attach run' does not show anything in my logs.
But as I remember this 'attach' runaway process always happened in GDB (but
I do not remember it in the past months) I think it would be most safe to just
solve it forever by [attached].

Doing:
gdb --pid=PID -ex run
Results in GDB getting a SIGTTIN, and thus ending stopped. That's
usually indicative of a missing target_terminal_ours call.
E.g., from the PR:
$ sleep 1h & p=$!; sleep 0.1; gdb -batch sleep $p -ex run
[1] 28263
[1] Killed sleep 1h
[2]+ Stopped gdb -batch sleep $p -ex run
The workaround is doing:
gdb -ex "attach $PID" -ex "run"
instead of
gdb [-p] $PID -ex "run"
With the former, gdb waits for the attach command to complete before
moving on to the "run" command, because the interpreter is in sync
mode at this point, within execute_command. But for the latter,
attach_command is called directly from captured_main, and thus misses
that waiting. IOW, "run" is running before the attach continuation
has run, before the program stops and attach completes. The broken
terminal settings are just one symptom of that. Any command that
queries or requires input results in the same.
The fix is to wait in catch_command_errors (which is specific to
main.c nowadays), just like we wait in execute_command.

This commit adds a new global flag show_debug_regs to common-debug.h
to replace the flag debug_hw_points used by gdbserver and by the
Linux x86 and AArch64 ports, and to replace the flag maint_show_dr
used by the Linux MIPS port.
Note that some debug printing in the AArch64 port was enabled only if
debug_hw_points > 1 but no way to set debug_hw_points to values other
than 0 and 1 was provided; that code was effectively dead. This
commit enables all debug printing if show_debug_regs is nonzero, so
the AArch64 output will be more verbose than previously.

This fixes two FAIL results on this testcase which were caused by a
misplaced "continue" command. This testcase used to end inferior's
execution too soon, causing the following tests to fail. Now we break
right after inferior's loop and perform the rest of the tests there.
gdb/testsuite/ChangeLog:
* gdb.fortran/array-element.exp: Remove unexpected "continue"
command in testcase. Simplify testcase.
