Handle pending stops from the Windows kernel
PR gdb/22992 concerns an assertion failure in gdb when debugging a
certain inferior:
int finish_step_over(execution_control_state*): Assertion `ecs->event_thread->control.trap_expected' failed.
Initially the investigation centered on the discovery that gdb was not
suspending other threads when attempting to single-step. This
oversight is corrected in this patch: now, when stepping a thread, gdb
will call SuspendThread on all other threads.
However, the bug persisted even after this change. In particular,
WaitForDebugEvent could see a stop for a thread that was ostensibly
suspended. Our theory of what is happening here is that there are
actually simultaneous breakpoint hits, and the Windows kernel queues
the events, causing the second stop to be reported on a suspended
thread.
In Windows 10 or later gdb could use the DBG_REPLY_LATER flag to
ContinueDebugEvent to request that such events be re-reported later.
However, relying on that did not seem advisable, so this patch instead
arranges to queue such "pending" stops, and then to report them later,
once the step has completed.
In the PR, Pedro pointed out that it's best in this scenario to
implement the stopped_by_sw_breakpoint method, so this patch does this
as well.

gdb: stop using host-dependent signal numbers in windows-tdep.c
The signal enumeration in windows-tdep.c is defined differently whether
it is compiled on Cygwin or not. This is problematic, since the code in
tdep files is not supposed to be influenced by the host platform (the
platform GDB itself runs on).
This makes a difference in windows_gdb_signal_to_target. An obvious
example of clash is SIGABRT. Let's pretend we are cross-debugging a
Cygwin process from a MinGW (non-Cygwin Windows) GDB. If GDB needs to
translate the gdb signal number GDB_SIGNAL_ABRT into a target
equivalent, it would obtain the MinGW number (22), despite the target
being a Cygwin process. Conversely, if debugging a MinGW process from a
Cygwin-hosted GDB, GDB_SIGNAL_ABRT would be converted to a Cygwin signal
number (6) despite the target being a MinGW process. This is wrong,
since we want the result to depend on the target's platform, not GDB's
platform.
This known flaw was accepted because at the time we had a single OS ABI
(called Cygwin) for all Windows binaries (Cygwin ones and non-Cygwin
ones). This limitation is now lifted, as we now have separate Windows
and Cygwin OS ABIs. This means we are able to detect at runtime whether
the binary we are debugging is a Cygwin one or non-Cygwin one.
This patch splits the signal enum in two, one for the MinGW flavors and
one for Cygwin, removing all the ifdefs that made it depend on the host
platform. It then makes two separate gdb_signal_to_target gdbarch
methods, that are used according to the OS ABI selected at runtime.
There is a bit of re-shuffling needed in how the gdbarch'es are
initialized, but nothing major.

symbols, so when we run the test-case using either target board readnow,
cc-with-gdb-index or cc-with-debug-names, we run into:
...
FAIL: gdb.dwarf2/imported-unit.exp: no static partial symbols in importing unit
...
Fix this by marking the test unsupported if there are no partial symbols.
Tested on x86_64-linux.

* lib/gdb.exp (psymtabs_p): New proc.
* gdb.dwarf2/imported-unit.exp: Mark "no static partial symbols in

This failure is due to a gcc bug that declares two instead of one symbols,

gdb: small cleanups in dwarf2_psymtab constructors
I noticed that only one of the two dwarf2_psymtab constructors are
actually used. The one that is used accepts an `addr` parameter (the
base text offset), but its sole caller passes a constant, 0. We want to
keep calling the three-arguments standard_psymtab constructor form,
however, since it differs from the two-arguments form in subtle ways.
Also, I believe the dwarf2_per_cu_data associated to the created
dwarf2_psymtab should be passed as a constructor argument. That will
help me in a future patchset, to convince myself that the `per_cu_data`
field can't be NULL.
So this patch:
- Removes the two-parameters constructor of dwarf2_psymtab, as it is
unused.
- Removes the `addr` parameter of the remaining constructor, passing 0
directly to the base class' constructor.
- Adds a `per_cu` parameter, to assign the `per_cu_data` field at
construction.
gdb/ChangeLog:
* dwarf2/read.h (struct dwarf2_psymtab): Remove two-parameters
constructor. Remove `addr` parameter from other constructor and
add `per_cu` parameter.
* dwarf2/read.c (create_partial_symtab): Update.

[gdb/symtab] Add symbol with inherited DW_AT_const_value to psymtabs
Consider the test-case added in this patch, with resulting dwarf (related to
variable aaa):
...
<0><d2>: Abbrev Number: 2 (DW_TAG_partial_unit)
<1><eb>: Abbrev Number: 4 (DW_TAG_variable)
<ec> DW_AT_name : aaa

<10e> DW_AT_name : <artificial>
<1><11b>: Abbrev Number: 3 (DW_TAG_variable)
<11c> DW_AT_abstract_origin: <0xeb>
...
When running the test-case, we see:
...
(gdb) p aaa^M
No symbol "aaa" in current context.^M
(gdb) FAIL: gdb.dwarf2/imported-unit-abstract-const-value.exp: p aaa
...
while with target board readnow.exp, we have:
...
(gdb) p aaa^M
$1 = 1^M
...
This is due to the fact that there's no aaa symbol in the partial symtabs:
...
Partial symtab for source file <artificial>@0x101 (object 0x351cf40)^M
...
Global partial symbols:^M
`main', function, 0x4004a7^M
^M
...
which is due to the fact that when attempting to add the symbol corresponding
to DIE 0x11b in add_partial_symbol:
...
(gdb) p /x pdi->sect_off
$4 = 0x11b
(gdb) p pdi.has_const_value
$5 = 0
...
it seems the DW_AT_const_value was not inherited from DIE 0xeb, and
consequently we leave without adding a partial symbol.
Fix this by making sure that partial_die_info::has_const_value is inherited
in partial_die_info::fixup.
Build and reg-tested on x86_64-linux.
Tested test-case with target boards readnow, cc-with-gdb-index and

[gdb/symtab] Fix check-psymtab failure for inline function
Consider test-case inline.c, containing an inline function foo:

Implement basic threading support in the NetBSD target
Use sysctl(3) as the portable interface to prompt NetBSD threads on

and newer.
Implement as part of nbsd_nat_target:

- thread_alive() - check whether a thread is alive
- post_attach() - updates the list of threads after attach
- update_thread_list() - updates the list of threads
- pid_to_str() - translates ptid to a descriptive string
There are two local static functions:
- nbsd_thread_lister() - generic LWP lister for a specified pid
- nbsd_add_threads() - utility to update the list of threads
Now, GDB on NetBSD can attach to a multithreaded process, spawn

Handle complex error type in read_base_type
It turns out there was one more bug in the earlier complex series:
read_base_type could cause an assertion failure on some platforms. I
found this running the AdaCore internal test suite, but you can also
see it by running gdb's "gdb.cp" tests for x86 (not x86-64).
In particular, the DW_ATE_complex_float case calls
dwarf2_init_complex_target_type, which calls dwarf2_init_float_type,
which can return a type using TYPE_CODE_ERROR.
This patch changes the DWARF reader to handle this case, the same way
that the f-lang.c patch did. Perhaps init_complex_type really should

gdb: use bfd_get_section_contents to read section contents in is_linked_with_cygwin_dll
The function is_linked_with_cygwin_dll currently uses
gdb_bfd_map_section to get some section contents. This is not ideal
because that memory, which is only used in this function, can't be
released. Instead, it was suggested to use
bfd_get_full_section_contents.
However, bfd_get_full_section_contents returns a newly allocated buffer,
which is not very practical to use with C++ automatic memory management
constructs. I decided to make gdb_bfd_get_full_section_contents, a
small alternative to bfd_get_full_section_contents. It is a small
wrapper around bfd_get_section_contents which returns the full contents
of the section in a gdb::byte_vector.
gdb_bfd_get_full_section_contents could be used at many places that
already allocate a vector of the size of the section and then call
bfd_get_section_contents. I think these call sites can be updated over
time.

Avoid assertion failure due to complex type change
Tankut Baris Aktemur pointed out that the recent series to change how
complex types are handled introduced a regression.
This assert in init_complex_type was firing:
gdb_assert (TYPE_CODE (target_type) == TYPE_CODE_INT
|| TYPE_CODE (target_type) == TYPE_CODE_FLT);
The problem was that f-lang.c could call init_complex_type with a type
whose code was TYPE_CODE_ERROR.
It seemed best to me to fix this in f-lang.c, rather than to change
init_complex_type to accept error types.

Micro-optimize partial_die_info::read
While profiling the DWARF reader, I noticed that
partial_die_info::read creates a vector to store attributes. However,
the vector is not needed, as this code only processes a single
attribute at a time.
This patch removes the vector. On my machine, this improves the time
of "./gdb ./gdb" from 2.22 seconds to 1.92 seconds (mean times over 10
runs).
Note that the attribute is initialized by read_attribute, so it does
not need any special initialization. Avoiding this also improves
performance a bit.

gdb: Don't remove duplicate entries from the line table

gdb: Add support for tracking the DWARF line table is-stmt field
A change was made in buildsym_compunit::record_line to remove
duplicate line table entries in some cases. This was an invalid
change, as these duplicate line table entries are used in _some_ cases
as part of prologue detection (see skip_prologue_using_sal).
It might be possible to identify those line table entries that are
required by skip_prologue_using_sal and only keep those duplicates
around, however, I have not done this here. The original duplicate
removal was done because (a) it was easy to implement, and (b) it
seemed obviously harmless.
As (b) is now known to be false, and implementation would be more
complex, and so (a) is also false. As such, it seems better to keep
all duplicates until an actual reason presents itself for why we
should remove any.
The original regression was spotted on RISC-V, which makes use of
skip_prologue_using_sal as part of riscv_skip_prologue. Originally I
created the test gdb.dwarf2/dw2-inline-small-func.exp, however, this
test will not compile on RISC-V as this target doesn't support
.uleb128 or .sleb128 assembler directives containing complex
expressions. As a result I added the gdb.opt/inline-small-func.exp
test, which exposes the bug on RISC-V, but obviously depends on the
compiler to produce specific DWARF information in order to expose the
bug. Still this test does ensure we always get the desired result,
even if the DWARF changes.
Originally the gdb.dwarf2/dw2-inline-small-func.exp test passed on
x86-64 even with the duplicate line table entries incorrectly
removed. The reason for this is that when a compilation unit doesn't
have a 'producer' string then skip_prologue_using_sal is not used,
instead the prologue is always skipped using analysis of the assembler
code.
However, for Clang on x86-64 skip_prologue_using_sal is used, so I
modified the gdb.dwarf2/dw2-inline-small-func.exp test to include a
'producer' string that names the Clang compiler. With this done the
test would fail on x86-64.
One thing to note is that the gdb.opt/inline-small-func.exp test might
fail on some targets. For example, if we compare sparc to risc-v by
looking at sparc32_skip_prologue we see that this function doesn't use
skip_prologue_using_sal, but instead uses find_pc_partial_function
directly. I don't know the full history behind why the code is like
it is, but it feels like sparc32_skip_prologue is an attempt to
duplicate some of the functionality of skip_prologue_using_sal, but
without all of the special cases. If this is true then the new test
could easily fail on this target, this would suggest that sparc should
consider switching to use skip_prologue_using_sal like risc-v does.

coff-go32-exe: support variable-length stubs
The stub size in GO32 executables has historically been fixed at 2048
bytes, due to hardcoded limitations in bfd. Recent patches to djgpp by
Stas Sergeev (CC'd) have pushed the stub right up to this limit, so if
any further expansion is desired, this must first be patched in bfd.
This series includes three patches: The first changes the meaning of
the bfd->origin field slightly, so that target code can use this to
specify an offset into the file where the actual bfd is located.
The second patch then uses this to enable support for variable-sized
stubs in the coff-go32-exe format.
The final patch is only a cleanup, it normalizes function and variable

gdbserver/linux-low: start turning linux target ops into methods
This is the beginning of a series of patches that convert the linux
low targets into classes derived from linux_process_target. At the
end of the series we obtain a class hierarchy that looks like this:
process_stratum_target
^
|
|-- linux_process_target
^
|
|-- x86_target (defined in linux-x86-low)
|-- aarch64_target (defined in linux-aarch64-low)
|-- ppc_target (defined in linux-ppc-low)
|-- ...
In several cases, linux_process_target simply forwards a target op
request to a corresponding linux_target_ops function. For these
cases, the definition in linux_process_target will be removed and the
definition will be left to the deriving linux low target class; using
inheritance provides a nice and natural, object-oriented
simplification in these cases.
The series converts linux_target_ops into protected methods of
linux_process_target one by one. Throughout the series, based on the
needs, static functions defined in linux-low.cc are converted to
private methods of linux_process_target as well. This is done either
as separate patches or as integrated into a patch that convert a
particular linux_target_op into a method.
The series ends with the patch titled "gdbserver/linux-low: delete
'linux_target_ops' and 'the_low_target'".
Built and regression-tested on x86_64-linux. The following linux low
targets have been built (but not tested) via cross-compilation:
aarch64, arm, m68k, mips, ppc, riscv, s390, sh, sparc. The other
targets (bfin, cris, crisv32, ia64, m32r, nios2, tic6x, tile, xtensa)
were neither built nor tested.

gdbserver: make linux target op 'cannot_store_register' a predicate function
The comment for the linux target op 'cannot_store_register' states the
following:
/* Returns 0 if we can store the register, 1 if we can not
store the register, and 2 if failure to store the register
is acceptable. */
There is only one low target, linux-ppc-low, that potentially returns
2. There are two places that call the 'cannot_store_register' target
op in linux-low.cc. None of these locations distinguish a '2' from a
'1'. Hence, to simplify the definition, make the function a predicate
that returns either 0 or 1. This is also consistent with the
companion function, 'cannot_fetch_register'.

FAIL: ld-ifunc/ifunc-10-x86-64
although ld -V does report the elf_x86_64 emulation as supported:
$ ./ld/ld-new -V
GNU ld (GNU Binutils) 2.34.50.
20200328
Supported emulations:
elf_x86_64_sol2
elf_x86_64
[...]
When using ld -m elf_x86_64_sol2 instead, one of the testcases links
successfully.
However, there's no point in pursuing this: Solaris does not support
ifunc, as can be seen in <sys/elf.h>:
/*
* GNU/Linux specific symbol type not used by Solaris
*/
#define STT_GNU_IFUNC 10
and never will, given that it has symbol capabilities as solution to
effectively the same problem:
http://www.linker-aliens.org/blogs/rie/entry/symbol_capabilitie/
Therefore this patch disables ifunc testing on Solaris completely by
removing Solaris from binutils/testsuite/lib/binutils-common.exp
(supports_gnu_osabi). The ifunc part is justified above. SHF_GNU_MBIND is
in the OS-specific range and conflicts with
#define SHF_SUNW_REALLOC 0x01000000 /* internal: krtld realloc */
While the comment suggests this might be relocatable without too much
problems, the description of mbind (no formal spec AFAICS, just the
comment in the binutils patch submission) strongly suggests that this
isn't relevant to Solaris at all.
Indirectly, clearing supports_gnu_osabi on Solaris disables
supports_gnu_unique. Again, Solaris <sys/elf.h> has
/*
* GNU/Linux specific binding not used by Solaris
*/
#define STB_GNU_UNIQUE 10
so this seems the right thing to do.
Afterwards, one can remove the explicit mentions of *-*-solaris2* in
quite a number of (but not all) the ld-ifunc dump file notarget lists.
There's one fallout, though: two gas tests now XPASS because they are
xfail'ed for !supports_gnu_osabi:
XPASS: mbind sections 12
XPASS: mbind section contents 16
XPASS: mbind sections 16
XPASS: mbind section contents 16
To fix that, I've changed
#xfail: ![supports_gnu_osabi]
to notarget.

x86_64-pc-linux-gnu, and i686-pc-linux-gnu.

[gdb/testsuite] Fix silent timeout in gdb.multi/multi-target.exp
While running test-case gdb.multi/multi-target.exp, I observed a silent
timeout related to "monitor exit".
By making the timeout explicit in an expect clause in gdbserver_gdb_exit:
...
+ timeout {
+ warning "Timed out waiting for EOF in server after $monitor_exit"
+ }
...
we get in the log:
...
monitor exit^M
"monitor" command not supported by this target.^M
(gdb) WARNING: Timed out waiting for EOF in server after monitor exit
...
What happens is the following:
- the inferior 5 is selected
- a breakpoint is set in inferior 1
- the breakpoint triggers and we switch to inferior 1
- setup is called by test_continue, which calls clean_restart, which calls
gdbserver_gdb_exit (due to load_lib gdbserver-support.exp)
- gdbserver_gdb_exit issues "monitor exit"
- gdb responds with "not supported by this target" because inferior 1 is
native
Fix this by keeping a list of server_spawn_id, and cleaning those up before
calling gdbserver_gdb_exit.
This reduces testing time from 1m22s to 32s.
gdb/testsuite/ChangeLog:
2020-04-02 Tom de Vries <tdevries@suse.de>
* lib/gdbserver-support.exp (gdbserver_exit): Factor out of ...
(gdbserver_gdb_exit): ... here. Add timeout warning.
* gdb.multi/multi-target.exp (server_spawn_ids): New global var.
(connect_target_extended_remote): Append new server_spawn_id to
server_spawn_ids.
(cleanup): New proc.
(setup, <toplevel>): Call cleanup.
