[gdb/testsuite] Fix gdb.tui/basic.exp with check-read1
With gdb.tui/basic.exp and check-read1, we run into (using -v for
verbose log):
...
^[[0+++ _csi_0 <<<>>>
ERROR: (DejaGnu) proc "_csi_0" does not exist.
...
In contrast, without check-read1, we have:
...
^[[0;10m<SNIP>+++ _csi_m <<<0;10>>>
...
The problem is that this regexp in _accept:
...
-re "^\x1b\\\[(\[0-9;\]*)(\[0-9a-zA-Z@\])" {
...
while matching the longer sequence '^[' '[' '0' ';' '1' '0' 'm', also matches
the shorter sequence '^[' '[' '0'.
The regexp attempts to match a CSI (Control Sequence Introducer) sequence, and
the final byte of such a sequence cannot be a digit.
Fix the regexp accordingly:
...
- -re "^\x1b\\\[(\[0-9;\]*)(\[0-9a-zA-Z@\])" {
+ -re "^\x1b\\\[(\[0-9;\]*)(\[a-zA-Z@\])" {

AArch64 pauth: Indicate unmasked addresses in backtrace
Armv8.3-a Pointer Authentication causes the function return address to be
obfuscated on entry to some functions. GDB must unmask the link register in
order to produce a backtrace.
The following patch adds markers of [PAC] to the bracktrace, to indicate
which addresses needed unmasking. This includes the backtrace when using MI.
For example, consider the following backtrace:
(gdb) bt
0 0x0000000000400490 in puts@plt ()
1 0x00000000004005dc in foo ("hello") at cbreak-lib.c:6
2 0x0000000000400604 [PAC] in bar () at cbreak-lib.c:12
3 0x0000000000400620 [PAC] in main2 () at cbreak.c:17
4 0x00000000004005b4 in main () at cbreak-3.c:10
The functions in cbreak-lib use pointer auth, which masks the return address
to the previous function, causing the addresses of bar (in the library) and main2
(in the main binary) to require unmasking in order to unwind the backtrace.
An extra bool is added alongside the prev_pc in the frame structure. At the
point at which the link register is unmasked, the AArch64 port calls into frame
to sets the bool. This is the most efficient way of doing it.
The marker is also added to the python frame printer, which is always printed if
set. The marker is not explicitly exposed to the python code.
I expect this will potentially cause issues with some tests in the testsuite
when Armv8.3 pointer authentication is used. This should be fixed up in the
the future once real hardware is available for full testsuite testing.

ld: use a specific linker script in BPF targets
This patch makes the elf64bpf emulation to use it's own linker script,
based on elf.sc. At the moment, the only change is that the BPF
executable doesn't define an entry symbol (BPF programs feature
several entry points scattered in several sections.)
This is a step towards the goal of generating proper ELF executables
that would be loaded by the kernel's libbpf. We are not there yet:
BPF "programs" should still be linked with -r.
This change removes a warning while linking executables, decreases the
number of unsupported tests in the target from 47 to 29, and increases
the number of expected passes from 104 to 145.
Regtested in x86_64 for all targets.

Add a selftest that checks documentation invariants.
Several approaches were discussed (mail or irc) to verify the invariants of
the GDB help documentation : checking with apropos ., modifying add_cmd
to do the check and output a warning, implement maintenance check-doc.
A selftest was finally chosen as:
* this can be run on demand, including by users if they want
to check user defined commands.
* it does not interact with the normal behaviour of apropos, define,
python, ...

Make first and last lines of 'command help documentation' consistent.
With this patch, the help docs now respect 2 invariants:
* The first line of a command help is terminated by a '.' character.
* The last character of a command help is not a newline character.
Note that the changes for the last invariant were done by Tom, as part of :
[PATCH] Remove trailing newlines from help text
https://sourceware.org/ml/gdb-patches/2019-06/msg00050.html
but some occurrences have been re-introduced since then.
Some help docs had to be rephrased/restructured to respect the above
invariants.
Before this patch, print_doc_line was printing the first line
of a command help documentation, but stopping at the first '.'
or ',' character.
This was giving inconsistent results :
* The first line of command helps was sometimes '.' terminated,
sometimes not.
* The first line of command helps was not always designed to be
readable/understandable/unambiguous when stopping at the first
'.' or ',' character.
This e.g. created the following inconsistencies/problems:
< catch exception -- Catch Ada exceptions
< catch handlers -- Catch Ada exceptions
< catch syscall -- Catch system calls by their names
< down-silently -- Same as the `down' command
while the new help is:
> catch exception -- Catch Ada exceptions, when raised.
> catch handlers -- Catch Ada exceptions, when handled.
> catch syscall -- Catch system calls by their names, groups and/or numbers.
> down-silently -- Same as the `down' command, but does not print anything.
Also, the command help doc should not be terminated by a newline
character, but this was not respected by all commands.
The cli-option -OPT framework re-introduced some occurences.
So, the -OPT build help framework was changed to not output newlines at the
end of %OPTIONS% replacement.
This patch changes the help documentations to ensure the 2 invariants
given above.
It implied to slightly rephrase or restructure some help docs.
Based on the above invariants, print_doc_line (called by
'apropos' and 'help' commands to print the first line of a command
help) now outputs the full first line of a command help.
This all results in a lot of small changes in the produced help docs.
There are less code changes than changes in the help docs, as a lot
of docs are produced by some code (e.g. the remote packet usage settings).

[PR build/24886] disable glibc mcheck support
This patch drops gdb's configury support for glibc's mcheck function.
It has been observed to cause false abort()s, because it is
thread-unsafe yet interposes every malloc/free operation. So if any
library transitively used by gdb also uses threads, then these
functions can easily corrupt their own checking data. These days, gcc
ASAN and valgrind provide high quality checking, and mcheck is
apparently itself being slowly deprecated.
So, let's stop linking to it. Attached patch drops the
autoconf/Makefile machinery for both gdb and gdbserver. No
testsuite-visible impact. IMHO not worth mentioning in NEWS.

Clean up source file error reporting
print_source_lines_base reopens the source file every time that a
source line is to be printed. However, there's no need to do this so

otherwise rely on the cache.
The code seems to try to avoid these multiple opens; at a guess I'd

Add file offsets to the source cache
Currently, gdb stores the number of lines and an array of file offsets
for the start of each line in struct symtab. This patch moves this
information to the source cache. This has two benefits.
First, it allows gdb to read a source file less frequently.
Currently, a source file may be read multiple times: once when
computing the file offsets, once when highlighting, and then pieces
may be read again while printing source lines. With this change, the
file is read once for its source text and file offsets; and then
perhaps read again if it is evicted from the cache.
Second, if multiple symtabs cover the same source file, then this will
share the file offsets between them. I'm not sure whether this
happens in practice.

to pull in objects from lib2.a as necessary, but not from lib1.a.

Use _() in calls to build_help
Currently some code in gdb uses build_help with N_(), like:
static const std::string compile_print_help
= gdb::option::build_help (N_("\
I believe this is incorrect. The N_ macro is used to mark text that
should end up in the message catalog, but which will be translated by
a later call to gettext.
However, in this case, there is no later call to gettext, so (if gdb
had translations), this text would remain untranslated.
Instead, I think using the ordinary _() macro is correct here.
Translators will have to know to preserve "%OPTIONS%" in the text --
but that seems both unavoidable and fine.
Tested by rebuilding as there's not much else to do.

The test-case is compiled once with nopie and once with pie, but in both cases

Allow nested function displays
In Ada, it's possible to have nested functions. However,
block.c:contained_in does not recognize this. Normally, this is no
problem, but if gdb is stopped inside a nested function, then you can
end up in the unexpected situation that "print" of an expression will
work, whereas "display" of the same expression will not -- because
contained_in returns 0.
This patch simply removes the BLOCK_FUNCTION check from contained_in.
The rationale here is that in languages without nested functions, this
will not cause any issues.

[gdb/testsuite] Fail in gdb_compile if nopie results in PIE executable

The FAIL happens because although the test specifies nopie, the exec is
in fact compiled as PIE. The "-fPIE -pie" options specified using the

overriding the nopie flags.
Fix this by checking in gdb_compile if the resulting exec is PIE despite of

Implement 'set print frame-info|frame-arguments presence'.
New settings allow to better control what frame information is printed.
'set print frame-info' allows to override the default frame information
printed when a GDB command prints a frame.
The backtrace command has a new option -frame-info to override
this global setting.
It is now possible to have very short frame information by using the
new 'set print frame-arguments presence' and
'set print frame-info short-location'.
Combined with 'set print address off', a backtrace will only show
the essential information to see the function call chain, e.g.:
(gdb) set print address off
(gdb) set print frame-arguments presence
(gdb) set print frame-info short-location
(gdb) bt
#0 break_me ()
#1 call_me (...)
#2 main ()
(gdb)
This is handy in particular for big backtraces with functions having
many arguments.
Python frame filter printing logic has been updated to respect the new
setting in non MI mode.
Also, the default frame information printed was inconsistent when
backtrace was printing the frame information itself, or when the python
frame filtering code was printing the frame information.
This patch changes the default of python frame filtering to have a
consistent behaviour regarding printed frame-information, whatever
the presence/activity/matches of python filters.

[gdb/testsuite] Fix gdb.base/define.exp with check-read1
When running gdb.base/define.exp with check-read1, we get:
...
show prompt^M
Gdb's prompt is "(gdb) ".^M
(gdb) PASS: gdb.base/define.exp: save gdb_prompt
set prompt \(blah\) ^M
(blah) PASS: gdb.base/define.exp: set gdb_prompt
set prompt (gdb) PASS: gdb.base/define.exp: reset gdb_prompt
^M
(gdb) FAIL: gdb.base/define.exp: define do-define
...
The problem is that the "$gdb_prompt $" regexp here:
...
gdb_test_multiple "set prompt $prior_prompt " "reset gdb_prompt" {
-re "$gdb_prompt $" {
pass "reset gdb_prompt"
}
}
...
triggers for the echoing of the command "set prompt $prior_prompt " rather
than for the prompt after the command has executed.
Fix this by changing the regexp to "\r\n$gdb_prompt $".
Tested on x86_64-linux.

[gdb/testsuite] Don't expect gdb_prompt in mi_skip_python_test
When running gdb.python/py-mi-events.exp with make check-read1, we get:
...
(gdb) ^M
python print ('test')^M
&"python print ('test')\n"^M
~"test\n"^M
^done^M
(gdb) FAIL: gdb.python/py-mi-events.exp: verify python support
^M
python print (sys.version_info[0])^M
&"python print (sys.version_info[0])\n"^M
~"2\n"^M
^done^M
(gdb) FAIL: gdb.python/py-mi-events.exp: check if python 3
^M
...
The FAILs happen as follows.
On one hand, skip_python_tests_prompt uses the prompt_regexp parameter for the
user_code argument of gdb_test_multiple:
...
proc skip_python_tests_prompt { prompt_regexp } {
global gdb_py_is_py3k
gdb_test_multiple "python print ('test')" "verify python support" {
-re "not supported.*$prompt_regexp" {
unsupported "Python support is disabled."
return 1
}
-re "$prompt_regexp" {}
}
gdb_test_multiple "python print (sys.version_info\[0\])" "check if python 3" {
-re "3.*$prompt_regexp" {
set gdb_py_is_py3k 1
}
-re ".*$prompt_regexp" {
set gdb_py_is_py3k 0
}
}
...
On the other hand, gdb_test_multiple itself uses $gdb_prompt:
...
-re "\r\n$gdb_prompt $" {
if ![string match "" $message] then {
fail "$message"
}
set result 1
}
...
So when mi_skip_python_test calls skip_python_tests_prompt with prompt_regexp
set to $mi_gdb_prompt:
...
proc mi_skip_python_tests {} {
global mi_gdb_prompt
return [skip_python_tests_prompt "$mi_gdb_prompt$"]
}
...
and expect reads "(gdb) " and tries to match it (due to the READ1=1 setting),
the user_code regexps using $prompt_regexp (set to $mi_gdb_prompt) don't match,
but the $gdb_prompt regexp in gdb_test_multiple does match.
Fix this by adding a prompt_regexp parameter to gdb_test_multiple, and using the
parameter in skip_python_tests_prompt.
Tested gdb.python/py-mi-events.exp with make check READ1=1 x86_64-linux.
