In a bigger series I'm working on, it is convenient to have a
libiberty hash table that manages objects allocated with 'new'. To
make this simpler, I wrote a small template function to serve as a
concise wrapper. Then I realized that this could be reused in a few
other places.

* dwarf2/read.c (allocate_type_unit_groups_table)

htab_delete_entry.

Now that libiberty includes htab_eq_string, we can remove the
identical function from gdb.

After seeing Simon's patch, I thought maybe it was finally time to
remove printfi_filtered and fprintfi_filtered, in favor of using the
"%*s" approach to indenting.
In this patch I took the straightforward approach of always adding a
leading "%*s", even when the format already started with "%s", to
avoid the trickier form of:
printf ("%*s", -indent, string)
Regression tested on x86-64 Fedora 32.
Let me know what you think.

This changes gdb/compile to use gdb_argv directly, rather than

Introduce the gdb_argv::as_array_view method, as a way to easily pass
the parsed arguments array to a function taking an array view. There is
currently one caller where we can use this (which prompted the
suggestion to implement this method).
Add some selftests for the new method, which at the same time test a
little bit gdb_argv. As far as I know, it's not tested currently.
gdb/ChangeLog:
* utils.h (class gdb_argv) <as_array_view>: New method.
* utils.c (gdb_argv_as_array_view_test): New.
(_initialize_utils): Register selftest.
* maint.c (maintenance_selftest): Use the new method.

I noticed a couple of spots that call malloc_failure, but that don't
need to.
* In xml-support.c, "concat" uses xmalloc, so cannot return NULL.
* In utils.c, "buildargv" also uses xmalloc, so can only return NULL
if the argument is empty.
Tested by the buildbot.

This function is not just slower than xxhash, it is slower than
even libiberty's iterative_hash, so there does not seem to be
a reason for it to exist.

I accidentally pushed the wrong version of the patch for commit
7bb43059820c5febb4509b15202a93efde442bc6 (where the review
comments were not fixed), and I did a bad conflict resolution
for ccb1ba62299edce72053dd567b9d384814e11885 leading to a
compile error when libxxhash is available. This fixes both
issues.

XXHash is faster than htab_hash_string:
------------------------------------------------------------
Benchmark Time CPU Iterations
------------------------------------------------------------
BM_xxh3 11 ns 11 ns 65887249
BM_xxh32 19 ns 19 ns 36511877

BM_hash_string 182 ns 182 ns 3853125
BM_iterative_hash 77 ns 77 ns 9087638
Unfortunately, XXH3 is still experimental (see
https://github.com/Cyan4973/xxHash#user-content-new-experimental-hash-algorithm)
However, regular XXH64 is still a lot faster than
htab_hash_string per my benchmark above. I used the
following string for the benchmark:
static constexpr char str[] = "_ZZZL13make_gdb_typeP7gdbarchP10tdesc_typeEN16gdb_type_creator19make_gdb_type_flagsEPK22tdesc_type_with_fieldsE19__PRETTY_FUNCTION__";
htab_hash_string is currently 4.35% + 7.98% (rehashing) of gdb
startup when attaching to Chrome's content_shell.
An additional 5.21% is spent in msymbol_hash, which does not use
this hash function. Unfortunately, since it has to lowercase the
string, it can't use this hash function.
BM_msymbol_hash 52 ns 52 ns 13281495
It may be worth investigating if strlen+XXHash is still faster than
htab_hash_string, which would make it easier to use in more places.
Debian ships xxhash as libxxhash{0,-dev}. Fedora ships it as xxhash-devel.

This introduces a few gdb-specific %p format suffixes. This is useful
for emitting gdb-specific output in an ergonomic way. It also yields
code that is more i18n-friendly.
The comment before ui_out::message explains the details.
Note that the tests had to change a little. When using one of the gdb
printf functions with styling, there can be spurious style changes
emitted to the output. This did not seem worthwhile to fix, as the
low-level output functions are rather spaghetti-ish already, and I
didn't want to make them even worse.
This change also necessitated adding support for "*" as precision and
width in format_pieces. These are used in various spots in gdb, and
it seemed better to me to implement them than to remove the uses.

I touched symtab.h and was surprised to see how many files were
rebuilt. I looked into it a bit, and found that defs.h includes
gdbarch.h, which in turn includes many things.
gdbarch.h is only needed by a minority ofthe files in gdb, so this
patch removes the include from defs.h and updates the fallout.
I did "wc -l" on the files in build/gdb/.deps; this patch reduces the
line count from 139935 to 137030; so there are definitely future
build-time savings here.
Note that while I configured with --enable-targets=all, it's possible
that some *-nat.c file needs an update. I could not test all of
these. The buildbot caught a few problems along these lines.

This is the next patch in the ongoing series to move gdbsever to the
top level.
This patch just renames the "common" directory. The idea is to do
this move in two parts: first rename the directory (this patch), then
move the directory to the top. This approach makes the patches a bit
more tractable.
I chose the name "gdbsupport" for the directory. However, as this
patch was largely written by sed, we could pick a new name without too
much difficulty.
Tested by the buildbot.

Have 'show style' and its subcommands using a style to style its output.
This allows the GDB user or developer to use 'show style' to visually see
with one command how all the current styles look like.
Add 2 new styles highlight style, title style and fputs_highlighted function.
Highlight style is used by fputs_highlighted to highlight the parts of
its char *STR argument that match a HIGHLIGHT regexp.
This (and the title style) will be used in a following patch.

'thread|frame apply CMD' launches CMD so that CMD output goes to a string_file.
This patch ensures that string_file for such CMD output contains
style escape sequences that 'thread|frame apply' will later on
output on the real terminal, so as to have CMD output properly styled.
The idea is to have the class ui_file having overridable methods
to indicate that the output to this ui_file should be done using
'terminal' behaviour such as styling.
Then these methods are overriden in string_file so that a specially
constructed string_file will get output with style escape sequences.
After this patch, the output of CMD by thread|frame apply CMD is styled
similarly as when CMD is launched directly.
Note that string_file (term_out true) could also support wrapping,
but this is not done (yet?).
Tested on debian/amd64.

This adds a function that can be used to reset terminal styles,
regardless of what style the low-level output routines currently think
is applied.
This is used to make "echo" and "printf" work properly when emitting
ANSI terminal escapes -- now gdb will reset the style at the end of
the command.

This adds some output styling to the CLI.
A style is currently a foreground color, a background color, and an
intensity (dim or bold). (This list could be expanded depending on
terminal capabilities.)
A style can be applied while printing. For ui-out, this is done by
passing the style constant as an argument. For low-level cases,
fprintf_styled and fputs_styled are provided.
Users can control the style via a number of new set/show commands. In
the interest of not typing many nearly-identical documentation
strings, I automated this. On the down side, this is not very
i18n-friendly.
I've chose some default colors to use. I think it would be good to
enable this by default, so that when users start the new gdb, they
will see the new feature.
Stylizing is done if TERM is set and is not "dumb". This could be
improved when the TUI is available by using the curses has_colors
call. That is, the lowest layer could call this without committing to
using curses everywhere; see my other patch for TUI colorizing.
I considered adding a new "set_style" method to ui_file. However,
because the implementation had to interact with the pager code, I
didn't take this approach. But, one idea might be to put the isatty
check there and then have it defer to the lower layers.

Some unaligned watchpoints were currently missed.
On old kernels as specified in
kernel RFE: aarch64: ptrace: BAS: Support any contiguous range (edit)
https://sourceware.org/bugzilla/show_bug.cgi?id=20207
after this patch some other unaligned watchpoints will get reported as false
positives.
With new kernels all the watchpoints should work exactly.
There may be a regresion that it now less merges watchpoints so that with
multiple overlapping watchpoints it may run out of the 4 hardware watchpoint
registers. But as discussed in the original thread GDB needs some generic
watchpoints merging framework to be used by all the target specific code.
Even current FSF GDB code does not merge it perfectly. Also with the more
precise watchpoints one can technically merge them less. And I do not think
it matters too much to improve mergeability only for old kernels.
Still even on new kernels some better merging logic would make sense.
There remains one issue:
kernel-4.15.14-300.fc27.armv7hl
FAIL: gdb.base/watchpoint-unaligned.exp: continue
FAIL: gdb.base/watchpoint-unaligned.exp: continue
(gdb) continue
Continuing.
Unexpected error setting watchpoint: Invalid argument.
(gdb) FAIL: gdb.base/watchpoint-unaligned.exp: continue
But that looks as a kernel bug to me.
(1) It is not a regression by this patch.
(2) It is unrelated to this patch.

Enabling "set debug lin-lwp 1" with the MI interpreter doesn't work.
When the sigchld_handler function wants to print a debug output
("sigchld\n"), it uses ui_file_write_async_safe. This ends up in the
default implementation of ui_file::write_async_safe, which aborts GDB.
This patch implements the write_async_safe method for mi_console_file.
The "normal" MI output is line buffered, which means the output
accumulates in m_buffer until a \n is written, at which point it's
flushed in m_raw. The implementation of write_async_safe provided by
this patch bypasses this buffer and writes directly to m_raw. There are
two reasons for this:
(1) Appending to m_buffer (therefore to an std::string) is probably not
async-safe, as it may allocate memory.
(2) We may have a partial output already in m_buffer, so that would lead
to some nested MI output, not so great.
There is probably still a chance to have bad MI output, if
sigchld_handler is invoked in the middle of mi_console_file's flush, and
the line being flushed is only partially sent to m_raw. The solution
would probably be to block signals during flushing. Since this is only
used for debug output, I don't know if it's worth the effort to do that.
To implement write_async_safe, I needed to use the fputstrn_unfiltered,
which does the necessary escaping (e.g. replace \n with \\n). I started
by adding printchar's callback parameters to fputstrn_unfiltered, to be
able to pass async-safe versions of them. It's not easy to provide an
async-safe version of do_fprintf, but it turns out that we can easily
replace printchar's callbacks with a single do_fputc quite easily. The
async-safe version of do_fputc simply calls the underlying ui_file's
write_async_safe method.

I wanted to use streq with std::unique in another (upcoming) patch in
this seres, so I changed it to return bool. To my surprise, this lead
to regressions. The cause turned out to be that streq was used as an
htab callback -- by casting it to the correct function type. This
sort of cast is invalid, so this patch adds a variant which is
directly suitable for use by htab. (Note that I did not add an
overload, as I could not get that to work with template deduction in
the other patch.)

This commit moves the path manipulation routines found on utils.c to a
new common/pathstuff.c, and updates the Makefile.in's accordingly.
The routines moved are "gdb_realpath", "gdb_realpath_keepfile" and
"gdb_abspath".
This will be needed because gdbserver will have to call "gdb_abspath"
on my next patch, which implements a way to expand the path of the
inferior provided by the user in order to allow specifying just the
binary name when starting gdbserver, like:
$ gdbserver :1234 a.out
With the recent addition of the startup-with-shell feature on
gdbserver, this scenario doesn't work anymore if the user doesn't have
the current directory listed in the PATH variable.
I had to do a minor adjustment on "gdb_abspath" because we don't have
access to "tilde_expand" on gdbserver, so now the function is using
"gdb_tilde_expand" instead. Otherwise, the code is the same.
Regression tested on the BuildBot, without regressions.

ARMv8 supports tagged address, that is, the top one byte in address
is ignored. It is always enabled on aarch64-linux. See
https://www.kernel.org/doc/Documentation/arm64/tagged-pointers.txt
The tag in the tagged address is modeled as non-significant bits in
address, so this patch adds a new gdbarch method significant_addr_bit and
clear the non-significant bits (the top byte in ARMv8) of the virtual
address at the point before passing address to target cache layer. IOW,
the address used in the target cache layer is already cleared.
Before this patch,
(gdb) x/x 0x0000000000411030
0x411030 <global>: 0x00000000
(gdb) x/x 0xf000000000411030
0xf000000000411030: Cannot access memory at address 0xf000000000411030
After this patch,
(gdb) x/x 0x0000000000411030
0x411030 <global>: 0x00000000
(gdb) x/x 0xf000000000411030
0xf000000000411030: 0x00000000
Note that I used address_significant in paddress, but it causes a
regression gdb.base/long_long.exp, because gdb clears the non-significant
bits in address, but test still expects them.
p/a val.oct^M
$24 = 0x2ee53977053977^M
(gdb) FAIL: gdb.base/long_long.exp: p/a val.oct

Trying to set a breakpoint in a function with an ABI tag does not work
currently. E.g., debugging gdb itself, we see this with the
"string_printf" function:
(top-gdb) b string_print [TAB]
(top-gdb) b string_printf[abi:cxx11](char const*, ...) [RET]
No source file named string_printf[abi.
Make breakpoint pending on future shared library load? (y or [n])
Quoting doesn't help:
(top-gdb) b 'string_printf[abi:cxx11]'(char const*, ...)
malformed linespec error: unexpected string, "(char const*, ...)"
(top-gdb) b 'string_printf[abi:cxx11](char const*, ...)'
No source file named string_printf[abi.
Make breakpoint pending on future shared library load? (y or [n]) n
This patch fixes this, and takes it a bit further.
The actual symbol name as demangled by libiberty's demangler is really
string_printf[abi:cxx11](char const*, ...)
however, this patch makes it possible to set the breakpoint with
string_printf(char const*, ...)
too. I.e., ignoring the ABI tag.
And to match, it teaches the completer to complete the symbol name
without the ABI tag, i.e.,
"string_pri<TAB>" -> "string_printf(char const*, ...)"
If however, you really want to break on a symbol with the tag, then
you simply start writing the tag, and GDB will preserve it, like:
"string_printf[a<TAB>" -> "string_printf[abi:cxx11](char const*, ...)"
Grows the gdb.linespec/ tests like this:
-# of expected passes 8977

currently "b func tion" manages to set a breakpoint at "function" !
All these years I had never noticed this, but now that the linespec
completer actually works, this easily happens by accident, with:
"b func t<tab>"
expecting to get "thread", but getting instead:
"b func tion"
...
Also, this:
"b rettypefunc<int>"
manages to set a breakpoint on "rettype func<int>()".
These things happen due to strcmp_iw "magic".
Fix it by teaching strcmp_iw about when can it skip whitespace. This
required handling user-defined operators, and scope operators,
complicating the code a bit, unfortunately. I added unit tests for
all the corner cases I stumbled on, as I was developing this, and then
in the end wrote a testsuite testcase covering many of the same things
and more (to be added later).

Summary:
- This is preparation for supporting wild name matching on C++ too.
- This is also preparation for TAB-completion fixes.
- Makes symbol name matching (think strcmp_iw) be based on a per-language method.
- Merges completion and non-completion name comparison (think
language_ops::la_get_symbol_name_cmp generalized).
- Avoid re-hashing lookup name multiple times
- Centralizes preparing a name for lookup (Ada name encoding / C++ Demangling),
both completion and non-completion.
- Fixes Ada latent bug with verbatim name matches in expressions
- Makes ada-lang.c use common|symtab.c completion code a bit more.
Ada's wild matching basically means that
"(gdb) break foo"
will find all methods named "foo" in all packages. Translating to
C++, it's roughly the same as saying that "break klass::method" sets
breakpoints on all "klass::method" methods of all classes, no matter
the namespace. A following patch will teach GDB about fullname vs
wild matching for C++ too. This patch is preparatory work to get
there.
Another idea here is to do symbol name matching based on the symbol
language's algorithm. I.e., avoid dependency on current language set.
This allows for example doing
(gdb) b foo::bar< int > (<tab>
and having gdb name match the C++ symbols correctly even if the
current language is C or Assembly (or Rust, or Ada, or ...), which can
easily happen if you step into an Assembly/C runtime library frame.
By encapsulating all the information related to a lookup name in a
class, we can also cache hash computation for a given language in the
lookup name object, to avoid recomputing it over and over.
Similarly, because we don't really know upfront which languages the
lookup name will be matched against, for each language we store the
lookup name transformed into a search name. E.g., for C++, that means
demangling the name. But for Ada, it means encoding the name. This
actually forces us to centralize all the different lookup name
encoding in a central place, resulting in clearer code, IMO. See
e.g., the new ada_lookup_name_info class.
The lookup name -> symbol search name computation is also done only
once per language.
The old language->la_get_symbol_name_cmp / symbol_name_cmp_ftype are
generalized to work with both completion, and normal symbol look up.
At some point early on, I had separate completion vs non-completion
language vector entry points, but a single method ends up being better
IMO for simplifying things -- the more we merge the completion /
non-completion name lookup code paths, the less changes for bugs
causing completion vs normal lookup finding different symbols.
The ada-lex.l change is necessary because when doing
(gdb) p <UpperCase>
then the name that is passed to write_ write_var_or_type ->
ada_lookup_symbol_list misses the "<>", i.e., it's just "UpperCase",
and we end up doing a wild match against "UpperCase" lowercased by
ada_lookup_name_info's constructor. I.e., "uppercase" wouldn't ever
match "UpperCase", and the symbol lookup fails.
This wouldn't cause any regression in the testsuite, but I added a new
test that would pass before the patch and fail after, if it weren't
for that fix.
This is latent bug that happens to go unnoticed because that
particular path was inconsistent with the rest of Ada symbol lookup by
not lowercasing the lookup name.
Ada's symbol_completion_add is deleted, replaced by using common
code's completion_list_add_name. To make the latter work for Ada, we
needed to add a new output parameter, because Ada wants to return back
a custom completion candidates that are not the symbol name.
With this patch, minimal symbol demangled name hashing is made
consistent with regular symbol hashing. I.e., it now goes via the
language vector's search_name_hash method too, as I had suggested in a
previous patch.
dw2_expand_symtabs_matching / .gdb_index symbol names were a
challenge. The problem is that we have no way to telling what is the
language of each symbol name found in the index, until we expand the
corresponding full symbol, which is off course what we're trying to
avoid. Language information is simply not considered in the index
format... Since the symbol name hashing and comparison routines are
per-language, we now have a problem. The patch sorts this out by
matching each name against all languages. This is inneficient, and
indeed slows down completion several times. E.g., with:
$ cat script.cmd
set pagination off
set $count = 0
while $count < 400
complete b string_prin
printf "count = %d\n", $count
set $count = $count + 1
end
$ time gdb --batch -q ./gdb-with-index -ex "source script-string_printf.cmd"
I get, before patch (-O2, x86-64):
real 0m1.773s
user 0m1.737s
sys 0m0.040s
While after patch (-O2, x86-64):
real 0m9.843s
user 0m9.482s
sys 0m0.034s
However, the following patch will optimize this, and will actually
make this use case faster compared to the "before patch" above:
real 0m1.321s
user 0m1.285s
sys 0m0.039s
