When running test-case gdb.dwarf2/fission-reread.exp with target board
cc-with-gdb-index, we run into:
...
gdb compile failed, warning: Could not find DWO TU \
fission-reread.dwo(0x9022f1ceac7e8b19) referenced by TU at offset 0x0 \
[in module outputs/gdb.dwarf2/fission-reread/fission-reread]
...
The problem is that the .dwo file is not found.
There's code added in the .exp file to make sure the .dwo can be found:
...
# Make sure we can find the .dwo file, regardless of whether we're
# running in parallel mode.
gdb_test_no_output "set debug-file-directory [file dirname $binfile]" \
"set debug-file-directory"
...
This works normally, but not for the gdb invocation done by cc-with-tweaks.sh
for target board cc-with-gdb-index.
Fix this by finding the full path to the .dwo file and passing it
to the compilation.
Tested on x86_64-linux with native and target boards cc-with-gdb-index,
cc-with-debug-names and readnow.

2021-02-01 Tom de Vries <tdevries@suse.de>
* gdb.dwarf2/fission-base.S: Pass -DDWO=$dwo.
* gdb.dwarf2/fission-loclists-pie.S: Same.
* gdb.dwarf2/fission-loclists.S: Same.
* gdb.dwarf2/fission-multi-cu.S: Same.

This makes --defsym support the same expressions as assignment in a
script. For example, --defsym 'HIDDEN(foo=0)', will define a hidden
visibility foo.
* ldgram.y (defsym_expr): Use assignment rule.
* ldlex.h (ldlex_defsym): Delete.
* ldlex.l (DEFSYMEXP, ldlex_defsym): Delete.
Parsing symbol or file/section names in ld linker scripts is a little
complicated. Inside SECTIONS, a name might be the start of an
expression or an output section. Is ".foo=x-y" a fancy section name
or is it the expression ".foo = x - y"? It isn't possible for a
single lookahead parser to decide, so the answer in this case is
that it's a section name. This is the reason why everyone writes
linker script assignment expressions with lots of white-space.
However, there are many places where the parser knows for sure that an
expression is expected. Those could be written without whitespace
given the first change to ldlex.l below. Unfortunately, that runs
into a lookahead problem. Optional expressions at the end of an
output section statement require the parser to look ahead one token in
expression context. For this example from standard scripts
.interp : { *(.interp) }
.note.gnu.build-id : { *(.note.gnu.build-id) }
at the end of the .interp closing brace, the parser is looking for
a possible memspec, phdr, fill or even an optional comma. The next
token is a NAME, but in expression context that NAME now doesn't
include '-' as a valid char. So the lookahead NAME is
".note.gnu.build" with an unexpected "-id" syntax error before the
colon. The rest of the patch involving ldlex_backup arranges to
discard that NAME token so that it will be rescanned in the proper
script context.
* ldgram.y (section): Call ldlex_backup. Remove empty action.
* ldlex.h (ldlex_backup): Declare.
* ldlex.l (<EXPRESSION>NAME): Don't use NOCFILENAMECHAR set of
chars, use SYMBOLNAMECHAR.
(ldlex_backup): New function.
While reviewing the Linux and FreeBSD core dumping code within GDB for
another patch series, I noticed that the code that collects the
registers for each thread and writes these into ELF note format is
basically identical between Linux and FreeBSD.
This commit merges this code and moves it into the gcore.c file,
which seemed like the right place for generic writing a core file
code.
The function find_signalled_thread is moved from linux-tdep.c despite
not being shared. A later commit will make use of this function.
There are a couple of minor changes to the FreeBSD target after this
commit, but I believe that these are changes for the better:
(1) For FreeBSD we always used to record the thread-id in the core file by
using ptid_t.lwp (). In contrast the Linux code did this:
/* For remote targets the LWP may not be available, so use the TID. */
long lwp = ptid.lwp ();
if (lwp == 0)
lwp = ptid.tid ();
Both target now do this:
/* The LWP is often not available for bare metal target, in which case
use the tid instead. */
if (ptid.lwp_p ())
lwp = ptid.lwp ();
else
lwp = ptid.tid ();
Which is equivalent for Linux, but is a change for FreeBSD. I think
that all this means is that in some cases where GDB might have
previously recorded a thread-id of 0 for each thread, we might now get
something more useful.
(2) When collecting the registers for Linux we collected into a zero
initialised buffer. By contrast on FreeBSD the buffer is left
uninitialised. In the new code the buffer is always zero initialised.
I suspect once the registers are copied into the buffer there's
probably no gaps left so this makes no difference, but if it does then
using zeros rather than random bits of GDB's memory is probably a good
thing.
Otherwise, there should be no other user visible changes after this
commit.
Tested this on x86-64/GNU-Linux and x86-64/FreeBSD-12.2 with no
regressions.

We renamed these years ago, but it looks like the cgen core missed the
TRACE_EXTRACT function, so these new ports still used the incompatible
common name. Fix those ports to use the right func.
When compiling we get the following warnings:
common/cgen-accfp.c: In function 'fixsfsi':
common/cgen-accfp.c:370:18: warning: pointer targets in passing argument 1 of 'sim_fpu_to32i' differ in signedness [-Wpointer-sign]

This port only had one minor warning left in it, so fix it and then
enable -Werror behavior by deleting the macro call. We'll use the
common default now (which is -Werror).
My recent rewrite of the nltvals generator fixed a bug where SYS_times
was not being exported for v850. But that in turn uncovered this bug
where the SYS_times codepath had a compile error.
This port only had one minor warning left in it, so fix it and then
enable -Werror behavior by deleting the macro call. We'll use the
common default now (which is -Werror).
Existing ports already have sizeof_pc set to the same size as sim_cia,
so simply make that part of the core code. We already assume this in
places by way of sim_pc_{get,set}, and this is how it's documented in
the sim-base.h API.
There is code to allow sims to pick different register word sizes from
address sizes, but most ports use the defaults for both (32-bits), and
the few that support multiple register sizes never change the address
size (so address defaults to register). I can't think of any machine
where the register hardware size would be larger than the address word
size either. We have ABIs that behave that way (e.g. x32), but the
hardware is still equivalent register sized.
When the target's PC is 64-bits, this shift expands into a range of
8 * 8 - 1 which doesn't work with 32-bit constants. Force it to be
a 64-bit value all the time and let the compiler truncate it.
This port doesn't build if these hardware modules are omitted, and
there's no reason we need to make it conditional at build time, so
always enable it. The hardware devices only get turned on if the
user requests it at runtime via hardware settings.
Consider the test-case small.c:
...
$ cat -n small.c
1 __attribute__ ((noinline, noclone))
2 int foo (char *c)
3 {
4 asm volatile ("" : : "r" (c) : "memory");
5 return 1;
6 }
7
8 int main ()
9 {
10 char tpl1[20] = "/tmp/test.XXX";
11 char tpl2[20] = "/tmp/test.XXX";
12 int fd1 = foo (tpl1);
13 int fd2 = foo (tpl2);
14 if (fd1 == -1) {
15 return 1;
16 }
17
18 return 0;
19 }
...
Compiled with gcc-8 and optimization:
...
$ gcc-8 -O2 -g small.c
...
We step through the calls to foo, but fail to visit line 13:
...
12 int fd1 = foo (tpl1);
(gdb) step
foo (c=c@entry=0x7fffffffdea0 "/tmp/test.XXX") at small.c:5
5 return 1;
(gdb) step
foo (c=c@entry=0x7fffffffdec0 "/tmp/test.XXX") at small.c:5
5 return 1;
(gdb) step
main () at small.c:14
14 if (fd1 == -1) {
(gdb)
...
This is caused by the following. The calls to foo are implemented by these
insns:
....
4003df: 0f 29 04 24 movaps %xmm0,(%rsp)
4003e3: 0f 29 44 24 20 movaps %xmm0,0x20(%rsp)
4003e8: e8 03 01 00 00 callq 4004f0 <foo>
4003ed: 48 8d 7c 24 20 lea 0x20(%rsp),%rdi
4003f2: 89 c2 mov %eax,%edx
4003f4: e8 f7 00 00 00 callq 4004f0 <foo>
4003f9: 31 c0 xor %eax,%eax
...
with corresponding line table entries:
...
INDEX LINE ADDRESS IS-STMT
8 12 0x00000000004003df Y
9 10 0x00000000004003df
10 11 0x00000000004003e3
11 12 0x00000000004003e8
12 13 0x00000000004003ed
13 12 0x00000000004003f2
14 13 0x00000000004003f4 Y
15 13 0x00000000004003f4
16 14 0x00000000004003f9 Y
17 14 0x00000000004003f9
...
Once we step out of the call to foo at 4003e8, we land at 4003ed, and gdb
enters process_event_stop_test to figure out what to do.
That entry has is-stmt=n, so it's not the start of a line, so we don't stop
there. However, we do update ecs->event_thread->current_line to line 13,
because the frame has changed (because we stepped out of the function).
Next we land at 4003f2. Again the entry has is-stmt=n, so it's not the start
of a line, so we don't stop there. However, because the frame hasn't changed,
we don't update update ecs->event_thread->current_line, so it stays 13.
Next we land at 4003f4. Now is-stmt=y, so it's the start of a line, and we'd
like to stop here.
But we don't stop because this test fails:
...
if ((ecs->event_thread->suspend.stop_pc == stop_pc_sal.pc)
&& (ecs->event_thread->current_line != stop_pc_sal.line
|| ecs->event_thread->current_symtab != stop_pc_sal.symtab))
{
...
because ecs->event_thread->current_line == 13 and stop_pc_sal.line == 13.
Fix this by resetting ecs->event_thread->current_line to 0 if is-stmt=n and
the frame has changed, such that we have:
...
12 int fd1 = foo (tpl1);
(gdb) step
foo (c=c@entry=0x7fffffffdbc0 "/tmp/test.XXX") at small.c:5
5 return 1;
(gdb) step
main () at small.c:13
13 int fd2 = foo (tpl2);
(gdb)
...

The problem is that the test-case expects to step past the retry line,
which is optional.
Fix this by removing the state tracking logic from the gdb_test_multiples. It

I spotted that every time thr_try_catch_cmd is called GDB has already
switched to the required thread. The call to switch_to_thread at the
head of thr_try_catch_cmd is therefore redundant.

that we already have the required thread selected.

The locator window, or status window as it is sometimes called is
handled differently to all the other windows.
The reason for this is that the class representing this
window (tui_locator_window) does two jobs, first this class represents
a window just like any other that has space on the screen and fills
the space with content. The second job is that this class serves as a
storage area to hold information about the current location that the
TUI windows represent, so the class has members like 'addr' and
'line_no', for example which are used within this class, and others
when they want to know which line/address the TUI windows should be
showing to the user.
Because of this dual purpose we must always have an instance of the
tui_locator_window so that there is somewhere to store this location
information.
The result of this is that the locator window must never be deleted
like other windows, which results in some special case code.
In this patch I propose splitting the two roles of the
tui_locator_window class. The tui_locator_window class will retain
just its window drawing parts, and will be treated just like any other
window. This should allow all special case code for this window to be
deleted.
The other role, that of tracking the current tui location will be
moved into a new class (tui_location_tracker), of which there will be
a single global instance. All of the places where we previously use
the locator window to get location information will now be updated to
get this from the tui_location_tracker.
There should be no user visible changes after this commit.

I think this makes the names of the methods clearer, especially for the

(which returns an arch no matter what). The name "arch_owner" will make
it intuitive that the method returns NULL if the type is not arch-owned.
Also, this frees the type::arch name, so we will be able to morph the
get_type_arch function into the type::arch method.

gdb: use get_standard_config_dir when looking for .gdbinit
GDB has been checking for ${XDG_CONFIG_HOME}/gdb/gdbinit on startup.
Most tests pass -nx to GDB to block loading of gdbinit files, but
there are a few tests (e.g. gdb.base/gdbinit-history.exp) that don't
use -nx and instead setup a fake HOME directory containing a gdbinit
file.
However, since the above commit, if XDG_CONFIG_HOME is set then once
-nx is no longer being passed GDB will load any gdbinit file it finds
in that directory, which could cause the test to fail.
As a concrete example:
$ mkdir -p fake_xdg_config_home/gdb/
$ cat <<EOF >fake_xdg_config_home/gdb/gdbinit
echo goodbye\n
quit
EOF
$ export XDG_CONFIG_HOME=$PWD/fake_xdg_config_home
$ make check-gdb TESTS="gdb.base/gdbinit-history.exp"
Should result in the test failing.
The solution I propose is to unset XDG_CONFIG_HOME in
default_gdb_init, we already unset a bunch of environment variables in
this proc.
gdb/testsuite/ChangeLog:
* lib/gdb.exp (default_gdb_init): Unset XDG_CONFIG_HOME.

...
The failure to access memory happens in i386_get_longjmp_target and is due to
glibc having pointer encryption (aka "pointer mangling" or "pointer guard") of
the long jump buffer. This is a known problem.
In create_longjmp_master_breakpoint (which attempts to install a master
longjmp breakpoint) a preference scheme is present, which installs a
probe breakpoint if a libc:longjmp probe is present, and otherwise falls back
to setting breakpoints at the names in the longjmp_names array.
But in fact, both the probe breakpoint and the longjmp_names breakpoints are
set. The latter ones are set when processing libc.so.debug, and the former
one when processing libc.so. In other words, this is the longjmp variant of
PR26881, which describes the same problem for master exception breakpoints.
This problem only triggers when the glibc debug info package is installed,
which is not due to the debug info itself in libc.so.debug, but due to the
minimal symbols (because create_longjmp_master_breakpoint uses minimal symbols
to translate the longjmp_names to addresses).
The problem doesn't trigger for -m64, because there tdep->jb_pc_offset is not
set.
Fix this similar to commit 1940319c0e (the fix for PR26881): only install
longjmp_names breakpoints in libc.so/libc.so.debug if installing the
libc:longjmp probe in libc.so failed.
Tested on x86_64-linux.

When running test-case gdb.ada/out_of_line_in_inlined.exp with target board
unix/-m32 on a system with gcc-10 default compiler, we run into:
...
(gdb) break foo_o224_021.child1.child2^M
Breakpoint 1 at 0x804ba59: foo_o224_021.child1.child2. (3 locations)^M
(gdb) FAIL: gdb.ada/out_of_line_in_inlined.exp: scenario=all: \
break foo_o224_021.child1.child2
...
The test does not expect the "3 locations" part.
Fix this by using gdb_breakpoint instead of gdb_test.
Tested on x86_64-linux.
