Update the ARC disassembler to supply style information to the
disassembler output. The output formatting remains unchanged.
opcodes/ChangeLog:
* disassemble.c (disassemble_init_for_target): Set
created_styled_output for ARC based targets.
* arc-dis.c (find_format_from_table): Use fprintf_styled_ftype
instead of fprintf_ftype throughout.
(find_format): Likewise.
(print_flags): Likewise.
(print_insn_arc): Likewise.

In commit 9d9dd861e98 ("[gdb/testsuite] Fix regression in
step-indirect-call-thunk.exp with gcc 7") I accidentally committed a duplicate
of supports_gnuc, which caused:
...
DUPLICATE: gdb.base/gdb-caching-proc.exp: supports_gnuc: consistency
...
Fix this by removing the duplicate.
Tested on x86_64-linux.

It is possible that a system might have a python3 executable, but no
python executable. For example, on my Fedora system the python2
package provides /usr/bin/python2, the python3 package provides
/usr/bin/python3, and the python-unversioned-command package provides
/usr/bin/python, which picks between python2 and python3.
It is quite possible to only have python3 available on a system.
Currently, when GDB configures, it looks for a 'python' executable.
If non is found then GDB will be built without python support. Or the
user needs to configure using --with-python=/usr/bin/python3.
This commit updates GDB's configure.ac script to first look for
'python', and then 'python3'. Now, on a system that only has a
python3 executable, GDB will automatically find, and use that in order
to provide python support, no user supplied configure arguments are
needed.
I've tested this on my local machine by removing the
python-unversioned-command package, confirming that there is no longer
a 'python' executable in my $PATH, and then rebuilding GDB from
scratch. GDB with this patch has python support.

Both forms were missing VexW0 (thus allowing Evex.W=1 to be encoded by
suitable means, which would cause #UD). The memory operand form further
was using the wrong Masking value, thus allowing zeroing-masking to be
encoded for the store form (which would again cause #UD).
|
|
This saves quite a number of shift instructions: The "operands" field
can now be retrieved by just masking (no shift), and extracting the
"extension_opcode" field now only requires a (signed) right shift, with
no prereq left one. (Of course there may be architectures where, in a
cross build, there might be no difference at all, e.g. when there are
suitable bitfield extraction insns.)

When running a task using parallel_for_each, we get the following
distribution:
...
Parallel for: n_elements: 7271
Parallel for: minimum elements per thread: 10
Parallel for: elts_per_thread: 1817
Parallel for: elements on worker thread 0 : 1817
Parallel for: elements on worker thread 1 : 1817
Parallel for: elements on worker thread 2 : 1817
Parallel for: elements on worker thread 3 : 0
Parallel for: elements on main thread : 1820
...
Note that there are 4 active threads, and scheduling elts_per_thread on each
of those handles 4 * 1817 == 7268, leaving 3 "left over" elements.
These leftovers are currently handled in the main thread.
That doesn't seem to matter much for this example, but for say 10 threads and
99 elements, you'd have 9 threads handling 9 elements and 1 thread handling 18
elements.
Instead, distribute the left over elements over the worker threads, such that
we have:
...
Parallel for: elements on worker thread 0 : 1818
Parallel for: elements on worker thread 1 : 1818
Parallel for: elements on worker thread 2 : 1818
Parallel for: elements on worker thread 3 : 0
Parallel for: elements on main thread : 1817

Use set_sanitizer_default for ASAN_OPTIONS in lib/gdb.exp.
This allows us to override the default detect_leaks=0 setting, by manually
doing:
...
$ export ASAN_OPTIONS=detect_leaks=1
$ make check

test-case gdb.dwarf2/gdb-add-index.exp with and without
"export ASAN_OPTIONS=detect_leaks=1".

Since commit 43127ae5714 ("Fix gdb.base/step-indirect-call-thunk.exp") I run
into:

gdb compile failed, gcc: error: unrecognized command line option \
'-fcf-protection=none'; did you mean '-flto-partition=none'?
UNTESTED: gdb.base/step-indirect-call-thunk.exp: failed to prepare

The problem is that -fcf-protection is supported starting gcc 8, but I'm using
system gcc 7.5.0.
Fix this by only adding -fcf-protection=none for gcc 8 and later.

gdb-add-index runs gdb with -iex 'set debuginfod enabled off'. If gdb
is not compiled against libdebuginfod this causes an unnecessary error
message to be printed to stderr indicating that gdb was not built with
debuginfod support.
Fix this by changing the 'set debuginfod enabled off' command to a
no-op when gdb isn't built with libdebuginfod.

gdb.base/maint.exp was using several gdb_expect statements, probably
because this test case predates the existance of gdb_test_multiple. This
commit updates the test case to use gdb_test_multiple, making it more
resilient to internal errors and such.
The only gdb_expect left in the testcase is one that specifically looks
for an internal error being triggered as a PASS.

The test gdb.base/infcall-nested-structs-c.exp fails on a gdb assert
in function ppc64_sysv_abi_return_value in file gdb/ppc-sysv-tdep.c. The
assert is due to the missing IEEE 128-bit support in file
gdb/ppc-sysv-tdep.c.
The IBM long double was the initial float 128-bit support added by IBM
The IEEE 128-bit support, which is similar IBM long double support, was
made the default starting with GCC 12. The floating point format
differences include the number of bits used to encode the exponent
and significand. Also, IBM long double values are passed in a pair of
floating point registers. The IEEE 128-bit value is passed in a single
vector register.
This patch fixes the gdb_assert (ok); in function
ppc64_sysv_abi_return_value in gdb/ppc-sysv-tdep.c by adding IEEE FLOAT
128-bit type support for PowerPC.
The patch has been tested on Power 10, ELFv2. It fixes the following list
of regression failures on Power 10:
gdb.base/infcall-nested-structs-c.exp 192
gdb.base/infcall-nested-structs-c++.exp 76
gdb.base/structs.exp 9
The patch has been tested on Power 8 BE which is ELFv1.

This adds a 'summary' mode to Value.format_string and to
gdb.print_options. For the former, it lets Python code format values
using this mode. For the latter, it lets a printer potentially detect
if it is being called in a backtrace with 'set print frame-arguments'
set to 'scalars'.
I considered adding a new mode here to let a pretty-printer see
whether it was being called in a 'backtrace' context at all, but I'm
not sure if this is really desirable.
|
|
PR python/17291 asks for access to the current print options. While I
think this need is largely satisfied by the existence of
Value.format_string, it seemed to me that a bit more could be done.
First, while Value.format_string uses the user's settings, it does not
react to temporary settings such as "print/x". This patch changes
this.
Second, there is no good way to examine the current settings (in
particular the temporary ones in effect for just a single "print").
This patch adds this as well.

Disable the Traceback Table generation on PowerPC for this test. The
Traceback Table consists of a series of bit fields to indicate things like
the Traceback Table version, language, and specific information about the
function. The Traceback Table is generated following the end of the code
for every function by default. The Traceback Table is defined in the
PowerPC ELF ABI and is intended to support debuggers and exception
handlers. The Traceback Table is displayed in the disassembly of functions
by default and is part of the function length. The table is typically
interpreted by the disassembler as data represented by .long xxx entries.
Generation of the Traceback Table is disabled in this test using the
PowerPC specific gcc compiler option -mtraceback=no, the xlc option
additional_flags-qtable=none and the clang optons
-mllvm -xcoff-traceback-table=false. Disabling the Traceback Table
generation in this test results in the gdb_test_multiple statement
correctly locating the address of the bclr instruction before the statement
"End of assembler dump." in the disassembly output.

Somehow, above, GDB re-added the zombie leader back before printing
"No unwaited-for children left.". The "only thread 3 left, main
thread terminated" test should have caught this, but didn't. That is
because the test's regexp has a ".*" after the part that matches
thread 3. This commit tightens that regexp to catch such a bug. It
also tightens the "only main thread left, thread 2 terminated" test's
regexp in the same way.

to be "-fcf-protection=none" for the test to compile on Intel.
The gcc command line "-mindirect-branch' is an Intel specific and will give
an error on other platforms. A check for X86 is added so the test will
only run on X86 platforms.
The patch has been tested and verified on Power 10 and Intel X86-64 systems

With a test like this:
1 #include <dlfcn.h>
2 int
3 main ()
4 {
5 dlsym (RTLD_DEFAULT, "FOO");
6 return 0;
7 }
and then "start" followed by "until 6", GDB currently incorrectly
stops inside the runtime loader, instead of line 6. Vis:
...
Temporary breakpoint 1, main () at until.c:5
4 {
(gdb) until 6

206 dl-error-skeleton.c: No such file or directory.
(gdb)
The problem is related to longjmp handling -- dlsym internally
longjmps on error. The testcase can be reduced to this:
1 #include <setjmp.h>
2 void func () {
3 jmp_buf buf;
4 if (setjmp (buf) == 0)
5 longjmp (buf, 1);
6 }
7
8 int main () {
9 func ();
10 return 0; /* until to here */
11 }
and then with "start" followed by "until 10", GDB currently
incorrectly stops at line 4 (returning from setjmp), instead of line
10.
The problem is that the BPSTAT_WHAT_CLEAR_LONGJMP_RESUME code in
infrun.c fails to find the initiating frame, and so infrun thinks that
the longjmp jumped somewhere outer to "until"'s originating frame.
Here:
case BPSTAT_WHAT_CLEAR_LONGJMP_RESUME:
{
struct frame_info *init_frame;
/* There are several cases to consider.
1. The initiating frame no longer exists. In this case we
must stop, because the exception or longjmp has gone too
far.
...
init_frame = frame_find_by_id (ecs->event_thread->initiating_frame);
if (init_frame) // this is NULL!
{
...
}
/* For Cases 1 and 2, remove the step-resume breakpoint, if it
exists. */
delete_step_resume_breakpoint (ecs->event_thread);
end_stepping_range (ecs); // case 1., so we stop.
}
The initiating frame is set by until_break_command ->
set_longjmp_breakpoint. The initiating frame is supposed to be the
frame that is selected when the command was issued, but
until_break_command instead passes the frame id of the _caller_ frame
by mistake. When the "until LINE" command is issued from main, the
caller frame is the caller of main. When later infrun tries to find
that frame by id, it fails to find it, because frame_find_by_id
doesn't unwind past main.
The bug is that we passed the caller frame's id to
set_longjmp_breakpoint. We should have passed the selected frame's id
instead.

minimal to ada to c. */

This improves the "set scheduler-locking" documentation in the GDB
manual:
- Use a table to describe the four available modes.
- Describe "step" in terms of "on" and "off".
- Tweak the "replay" mode's description to describe replay first
instead of recording, and also mention how the mode behaves during
normal execution.
- Say what is the default mode.

The cu->per_cu->lang field was added to carry information from the initial
partial symtabs phase to the symtab expansion phase, for the benefit of a
particular optimization in process_imported_unit_die.
Other uses have been added, but since the first phase now has been
parallelized, those have become problematic and sources of race conditions.
Fix this by adding dwarf2_cu::lang () and using it where we can to replace
cu->per_cu->lang () with cu->lang ().
Also assert in dwarf2_cu::lang () that we're not returning language_unknown.

When building gdb with -fsanitize=address we run into:
...
builtin_spawn gdb -nw -nx -iex set height 0 -iex set width 0 -data-directory \
build/gdb/data-directory^M
==10637==ASan runtime does not come first in initial library list; you \
should either link runtime to your application or manually preload it with \
LD_PRELOAD.^M
ERROR: GDB process no longer exists
...
Prevent the ASan runtime error by using
ASAN_OPTIONS=verify_asan_link_order=0. This makes both test-cases pass.
Tested on x86_64-linux.

Add a new file tsan-suppressions.txt, to suppress the "unlock unlocked mutex"
problem in ncurses, filed in PR29328.
The file is added to the TSAN_OPTIONS in lib/gdb.exp.

When building gdb with gcc 4.8.5, we run into problems due to unconditionally
using:
...
gdb_static_assert (std::is_trivially_copyable<packed>::value);
...
in gdbsupport/packed.h.
Fix this by guarding the usage with HAVE_IS_TRIVIALLY_COPYABLE.
Tested by doing a full gdb build with gcc 4.8.5.
