Convert tid_range_parser and get_number_or_range to classes
This converts tid_range_parser and get_number_or_range to be classes.
The various tid_range_parser_* and get_number_or_range_* functions
become methods on the respective classes. Then it updates the users
to follow.
The rationale for the change is that this provides better
encapsulation. For example, this forced me to think of a better
interface between tid_range_parser and get_number_or_range, since the
former peeked into the latter's internals a bit too much. That ended
up resulting mostly in these two not-just-straight-1-1 changes:
void
-tid_range_parser_skip (struct tid_range_parser *parser)
+tid_range_parser::skip_range ()
{
...
- tid_range_parser_init (parser, parser->range_parser.end_ptr,
- parser->default_inferior);
+ m_range_parser.skip_range ();
+ init (m_range_parser.string (), m_default_inferior);
}
and:
/* If we successfully parsed a thread number or finished parsing a
thread range, switch back to assuming the next TID is
inferior-qualified. */
- if (parser->range_parser.end_ptr == NULL
- || parser->range_parser.string == parser->range_parser.end_ptr)
+ if (!m_range_parser.in_range ())
{
For the same reason (encapsulation), this moves the enum
tid_range_state definition to within the tid_parser class's scope,
since that is private implementation detail.
While at it, switch to use "bool" for booleans.

Fixup gdb.python/py-value.exp for bare-metal aarch64-elf
I noticed that testing aarch64-elf gdb with a physical board
ran into issues with gdb.python/py-value.exp. Further investigation showed
that we were actually trying to dereference a NULL pointer (argv) when trying
to access argv[0].
Being bare-metal, argv is not guaranteed to be valid. So we need to make sure
argv is sane before accessing argv[0].
The following patch fixes up the test program to check for a NULL argv and also
improves the testcase a bit so it doesn't have to work with a hardcoded argc
value.
Regression-tested on x86-64 Ubuntu 16.04.

Always descend into output section statements in lang_do_assignments
See https://sourceware.org/ml/binutils/2016-07/msg00091.html
This patch stop --gc-sections elf_gc_sweep_symbol localizing symbols
that ought to remain global.
The difficulty with always descending into output section statements
is that symbols defined by the script in such statements don't have
a bfd section when lang_do_assignments runs early in the link process.
There are two approaches to curing this problem. Either we can
create the bfd section early, or we can use a special section. This
patch takes the latter approach and uses bfd_und_section. (Creating
bfd sections early results in changed output section order, and thus
lots of testsuite failures. You can't create all output sections
early to ensure proper ordering as KEEP then stops empty sections
from being stripped.)
The wrinkle with this approach is that some code that runs at
gc-sections time needs to be made aware of the odd defined symbols
using bfd_und_section.

MIPS64: Adjust cfi* testcases.
The CFI* testcases fail on MIPS64 because the augmentation string does
not match the regexp. This is because MIPS64 doesn't use the default of
4 for DWARF2_FDE_RELOC_SIZE which ends up as "b" in the augmentation
string. MIPS64 uses the address size which is 8 resulting in "c".
Adding c to the regexp fixes a couple of them. Others also need
adjustments in the FDE header lines due to different

mips-tdep: Make FCRs always 32-bit
Fix a regression from commit
f8b73d13b7ca ("Target-described register
support for MIPS"),
<https://sourceware.org/ml/gdb-patches/2007-05/msg00340.html>,
<https://sourceware.org/ml/gdb-patches/2007-06/msg00256.html>, which
caused Floating Point Control Registers (FCRs) to be shown as 64-bit
with 64-bit targets.
This came from the legacy register format where all raw registers
matched the width of the architecture regardless of their actual size.
The correct size was then set in `mips_register_type' for cooked
registers presented to the user, which in the case of FCRs meant the
cooked size was always forced to 32 bits, reflecting their actual
hardware size, even though the raw format carried them in 64-bit
quantities on 64-bit targets. The upper 32 bits carried in the raw FCR
format have always been don't-cares, not actually retrieved from
hardware and never written back.
With the introduction of XML register descriptions the layout of
previously defined raw registers has been preserved, so as to keep
existing register handling code unchanged and make it easier for GDB and
`gdbserver' to interact with each other whether neither, either or both
parties talking over RSP support XML register descriptions. For the
XML-described case however `mips_register_type' is not used in raw to
cooked register conversion, so any special cases coded there are not
taken into account.
Instead a new function, `mips_pseudo_register_type', has been introduced
to handle size conversion, however lacking the special case for FCRs for
the Linux and the now defunct IRIX target. The correct size has been
maintained for embedded targets however, due to the bundling of FCRs
with the embedded registers under the `rawnum >= MIPS_EMBED_FP0_REGNUM +
32' condition.
Add the missing case to `mips_pseudo_register_type' then, referring to
the FCR indices explicitly, and observing that between
`MIPS_EMBED_FP0_REGNUM + 32' and `MIPS_FIRST_EMBED_REGNUM' there is an
unused register slot whose contents are ignored so with the removal of
embedded FCRs from under that condition we don't have to care about it
and we can refer to the embedded registers starting from
MIPS_FIRST_EMBED_REGNUM instead.
Add a test case too so that we have means to check automatically that
the correct user-visible size of FCRs is maintained.

This is GDB trying to print the location spec of the JIT event
breakpoint, but that's an internal breakpoint without one.
If I add a NULL check, then we see that the JIT breakpoint is now
pending (because its location has shlib_disabled set):
(gdb) maint info breakpoints
Num Type Disp Enb Address What
[...]
-8 jit events keep y <PENDING> inf 1
[...]
But that's incorrect. GDB should have managed to recreate the JIT
breakpoint's location for the second run. So the problem is
elsewhere.
The problem is that if the JIT loads at the same address on the second
run, we never recreate the JIT breakpoint, because we hit this early
return:
static int
jit_breakpoint_re_set_internal (struct gdbarch *gdbarch,
struct jit_program_space_data *ps_data)
{
[...]
if (ps_data->cached_code_address == addr)
return 0;
[...]
delete_breakpoint (ps_data->jit_breakpoint);
[...]
ps_data->jit_breakpoint = create_jit_event_breakpoint (gdbarch, addr);
Fix this by deleting the breakpoint and discarding the cached code
address when the objfile where the previous JIT breakpoint was found
is deleted/unloaded in the first place.
The test that was originally added for PR11094 doesn't trip on this
because:
#1 - It doesn't test the case of the JIT descriptor's address _not_
changing between reruns.
#2 - And then it doesn't do "maint info breakpoints", or really
anything with the JIT at all.
#3 - and even then, to trigger the problem the JIT descriptor needs
to be in a separate library, while the current test puts it in
the main program.
The patch extends the test to cover all combinations of these
scenarios.

Fix a few gdb.base/jit-simple.exp problems

(gdb) PASS: gdb.base/jit-simple.exp: blah 1

(gdb) print &__jit_debug_descriptor
$2 = (struct jit_descriptor *) 0x601040 <__jit_debug_descriptor>
(gdb) PASS: gdb.base/jit-simple.exp: blah 1
All tests PASSed, but note the "Unsupported JIT protocol version 4"
message.
Also notice that "__jit_debug_descriptor" has the same address before
and after the rerun, while the test is built in a way that should make
that address change between runs.
The test doesn't catch any of this because it doesn't compare
before/after addresses.
And then notice the "blah 1" test messages. "blah" is clearly a WIP
message, but it should be at least "blah 2" the second time. :-)
The reason this sometimes happens is that the test recompiles the
program and expects gdb to reload it automaticallyt on "run". However,
if the original program and the new recompilation happen to be in the
same second, then gdb does not realize that the binary needs to be
reloaded. (This is an old problem out of scope of this series.) If
that happens, then GDB ends up using the wrong symbols for the program
that it spawns, reads the JIT descriptor out of the wrong address,
finds garbage, and prints that "unsupported version" notice.
Fix that in the same way gdb.base/reread.exp handles it -- by sleeping
one second before recompiling.

Allow DW_OP_GNU_uninit in dwarf_expr_require_composition
In DWARF expression handling, some operators are required to be either
at the end of an expression or followed by a composition operator. So
far only the operators DW_OP_reg0-31 were allowed to be followed by
DW_OP_GNU_uninit instead, and particularly DW_OP_regx was not, which is
obviously inconsistent.
This patch allows DW_OP_GNU_uninit after all operators requiring a
composition, to simplify the code and make it more consistent. This

leads to a DWARF location description resulting in an uninitialized

Fold arithmetic integer expressions
Commit

ASSERT (((__hyp_idmap_text_end - (__hyp_idmap_text_start
& ~ (((0x1 << 0xc) - 0x1))))
<= (0x1 << 0xc)), HYP init code too big or misaligned)
Due to some insanity in ld expression evaluation, the integer values
0x1 and 0xc above are treated as absolute addresses (ie. they have an
associated section, *ABS*, see exp_fold_tree_1 case etree_value) while
the expression (0x1 << 0xc) has a plain number result. The left hand
side of the inequality happens to evaluate to a "negative" .text
section relative value. Comparing a section relative value against an
absolute value works since the section relative value is first
converted to absolute. Comparing a section relative value against a
number just compares the offsets, which fails since the "negative"
offset is really a very large positive number.
This patch works around the problem by folding integer expressions, so
the assert again becomes
ASSERT (((__hyp_idmap_text_end - (__hyp_idmap_text_start
& 0xfffffffffffff000))
<= 0x1000), HYP init code too big or misaligned)

Add test for user context selection sync
This patch adds a test to verify that events are sent properly to all

The goal of the C test file is to provide two threads that are stopped with the

helps us know when the child threads are started. Then, scheduler-locking is

Emit inferior, thread and frame selection events to all UIs
With this patch, when an inferior, thread or frame is explicitly
selected by the user, notifications will appear on all CLI and MI UIs.
When a GDB console is integrated in a front-end, this allows the
front-end to follow a selection made by the user ont he CLI, and it
informs the user about selection changes made behind the scenes by the
front-end.
This patch addresses PR gdb/20487.
In order to communicate frame changes to the front-end, this patch adds
a new field to the =thread-selected event for the selected frame. The
idea is that since inferior/thread/frame can be seen as a composition,
it makes sense to send them together in the same event. The vision
would be to eventually send the inferior information as well, if we find
that it's needed, although the "=thread-selected" event would be
ill-named for that job.
Front-ends need to handle this new field if they want to follow the
frame selection changes that originate from the console. The format of
the frame attribute is the same as what is found in the *stopped events.
Here's a detailed example for each command and the events they generate:
thread
------
1. CLI command:
thread 1.3
MI event:
=thread-selected,id="3",frame={...}
2. MI command:

inferior
--------
Inferior selection events only go from the console to MI, since there's
no way to select the inferior in pure MI.
1. CLI command:
inferior 2
MI event:
=thread-selected,id="3"
Note that if the user selects an inferior that is not started or exited,
the MI doesn't receive a notification. Since there is no threads to
select, the =thread-selected event does not apply...
2. MI command (CLI-in-MI):
inferior 2
MI event/reply:
&"inferior 2\n"
~"[Switching to inferior 2 ...]"
=thread-selected,id="4",frame={level="0"...}
^done
Internal implementation detail: this patch makes it possible to suppress
notifications caused by a CLI command, like what is done in mi-interp.c.
This means that it's now possible to use the
add_com_suppress_notification function to register a command with some
event suppressed. It is used to implement the select-frame command in
this patch.
The function command_notifies_uscc_observer was added to extract
the rather complicated logical expression from the if statement. It is
also now clearer what that logic does: if the command used by the user
already notifies the user_selected_context_changed observer, there is
not need to notify it again. It therefore protects again emitting the
event twice.
No regressions, tested on ubuntu 14.04 x86 with target boards unix and
native-extended-gdbserver.

PR 20627: Use resume_stop to stop lwp
Commit
049a8570 (Use target_continue{,_no_signal} instead of target_resume)
replaces the code stopping lwp with target_continue_no_signal in
target_stop_and_wait, like this,
- resume_info.thread = ptid;
- resume_info.kind = resume_stop;
- resume_info.sig = GDB_SIGNAL_0;
- (*the_target->resume) (&resume_info, 1);
+ target_continue_no_signal (ptid);
the replacement is not equivalent, and it causes PR 20627. This patch
is just to revert that change.
