There are a handful of spots in gdb that validly call abort. This
patch adds the appropriate ARI marker to these lines, to silence the
ARI report. This also removes the "fix" call for "abort" from
gdb_ari.sh; it was incorrect and now is not needed.
gdb/ChangeLog
2019-12-13 Tom Tromey <tromey@adacore.com>
* contrib/ari/gdb_ari.sh: Remove "fix" call for abort.
* utils.c (abort_with_message, dump_core, internal_vproblem): Add
ARI marker to abort.
* event-top.c (handle_sigsegv): Add ARI marker to abort.

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.

2019-12-12 Tom Tromey <tromey@adacore.com>
* xml-support.c (xml_fetch_content_from_file): Don't call
malloc_failure.
* utils.h (class gdb_argv): Remove malloc_failure comment.
* utils.c (gdb_argv::reset): Don't call malloc_failure.

On irc, Christian pointed out that print_sys_errmsg could be
simplified by avoiding alloca entirely. This patch implements this.

Also stores the result in a thread-local static variable and
changes the return value to a const char*.
This is already important because Guile creates threads and
Python can create threads, but with the patch series here:
https://gnutoolchain-gerrit.osci.io/r/c/binutils-gdb/+/176
GDB itself will create threads, too.

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.
gdb/ChangeLog:
2019-10-22 Christian Biesinger <cbiesinger@google.com>
* symtab.c (struct demangled_name_entry): Add a constructor.
(free_demangled_name_entry): New function to call the destructor
for demangled_name_entry.

htab_create_alloc.
(symbol_set_names): Call placement new for demangled_name_entry.
* utils.c: No longer include xxhash.h here, now that fast_hash
is inlined in the header.
* utils.h: Instead, include it here.

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_xxh64 16 ns 16 ns 42964585
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.

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).

This adds more styling to the disassemble command. In particular,
addresses and function names in the disassembly are now styled.
This required fixing a small latent bug in set_output_style. This
function always passed NULL to emit_style_escape; but when writing to
a file other than gdb_stdout, it should emit the style escape
directly. (FWIW this is another argument for better integrating the
pager with ui_file and getting rid of this entire layer.)

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.

The deprecated_interactive_hook is not used within GDB. It is used in
gdbtk, however this patch removes that use:
https://sourceware.org/ml/insight/2019-q2/msg00001.html

This patch removes it. There should be no user visible changes after
this commit.

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.

When merging commit 99f20f ("Fix style bug when paging") to master, I
had to make some changes to get it to compile again. Unfortunately, I
must not have added these to the index at the correct time, because
they were not committed.
This patch fixes the problem.

Philippe pointed out a styling bug that would occur in some conditions
when paging:
https://sourceware.org/ml/gdb-patches/2019-04/msg00101.html
I was finally able to reproduce this, and this patch fixes the bug.
The problem occurred when text overflowed the line, causing a
pagination prompt, but when no wrap column had been set. In this
case, the current style was reset to show the prompt, but then not
reset back to the previously applied style before emitting the rest of
the line.
The fix is to record the applied style in this case, and re-apply it
afterward -- but only if the pager prompt was emitted, something that
the existing style.exp pointed out on the first, more naive, version
of the patch.
Tested on x86-64 Fedora 29.

'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.

A customer noticed some mildly odd MI output, where CLI output was
split into multiple MI strings at unusual boundaries, like this:
~"$1 = (b => true"
~", p => 0x407260"
This is technically correct according to the MI spec, but still
unusual, in that there's no particular reason for the string to be
split where it is.
I tracked this down to a call to gdb_flush in generic_val_print.
Then, I went through all calls to gdb_flush and removed the ones I
thought were superfluous. In particular:
* Any call in the value-printing code;
* Likewise the type-printing code (just a single call); and
* Any call that immediately followed a printf that obviously
ended with a newline, my belief being that gdb's standard output
streams are line buffered (by inheriting the behavior from stdio)
Regression tested on x86-64 Fedora 29.
I didn't add a new test case. I tend to think we don't necessarily
want to specify this behavior in the tests. Let me know what you
think of this.

When we cap the height/width sizes before passing to readline, tweak
the corresponding command variable to show "unlimited":
(gdb) set height 0x8000
(gdb) show height
Number of lines gdb thinks are in a page is unlimited.
Instead of the current output:
(gdb) set height 0x8000
(gdb) show height
Number of lines gdb thinks are in a page is 32768.

GDB calls rl_set_screen_size in readline with the current screen size,
measured in rows and columns. To represent "infinite" sizes, GDB
passes in INT_MAX; however, since rl_set_screen_size internally
multiplies the number of rows and columns, this causes a signed
integer overflow. To prevent this we can instead pass in the
approximate square root of INT_MAX (which is still reasonably large),
so that even when the number of rows and columns is "infinite" we
don't overflow.

I believe this fixes all the pager output problems with styling that
Philippe pointed out, plus at least one more. The patch is somewhat
hard to reason about, so you may wish to give it a try. Even writing
the tests was hard.
This removes the style caching, because it was difficult to keep the
style cache correct in all cases. Since this would cause more style
escapes to be emitted, instead it changes fputs_styled to try to avoid
unnecessary changes.
Another bug was that the wrap buffer was not flushed in the case where
wrap_column==0. In the old (pre-patch series) code, characters were
directly emitted in this case; so flushing the wrap buffer here
restores this behavior.
On error the wrap buffer must be emptied. Otherwise, interrupting
output can leave characters in the buffer that will be emitted later.
As discussed on gdb-patches, this fixes the ada-lang.c problem where
filtered and unfiltered printing were mixed. Now user_select_syms
uses filtered printing, which is what its callees were already doing.
Finally, it was possible for source line highlighting to be garbled
(and invalid escape sequences emitted) if the pager was invoked at the
wrong spot. To fix this, the patch arranges for source line escapes
to always be emitted as a unit.

This commit applies all changes made after running the gdb/copyright.py
script.
Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header
was sent to gcc-patches first.

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.

Currently wrap buffering is implemented by allocating a string that is
the same width as the window, and then writing characters into it.
However, if gdb emits terminal escapes, then these could possibly
overflow the buffer.
To prevent this, change the wrap buffer to be a std::string and update
the various uses.
This also changes utils.c to always emit characters to the wrap
buffer. This simplifies future patches which emit terminal escape
sequences, and also makes it possible for the "echo" and "printf"
commands to be used to emit terminal escapes and have these work in
the TUI.

configure checks for declarations of free, malloc, and realloc; but
the results are only used in a single spot: utils.c. I think these
checks are long since obsolete, so this patch removes them.
Grepping the entire tree for these HAVE_DECL_ symbols, the only uses
of possible interest to gdb come from bfd/sysdep.h; but this is not
(nor should be) included by gdb. (And furthermore I think the code
there is probably also obsolete.)

This adds a "continue" response to the pager. If the user types "c"
in response to the pager prompt, pagination will be disabled for the
duration of one command -- but re-enabled afterward. This is handy if
you type a command that produces a lot of output, and you don't want
to baby-sit it by typing "return" each time the prompt comes up.

This patch fixes a bug introduced by fix to AArch64 pointer tagging.
In our fix for tagged pointer support our agreed approach was to sign
extend user-space address after clearing tag bits. This is not same
for all architectures and this patch allows sign extension for
addresses on targets which specifically set significant_addr_bit.
More information about patch that caused the issues and discussion
around tagged pointer support can be found in links below:

The function interp_ui_out simply calls the interp_ui_out method.
However, if it is passed a NULL interpreter, it first finds the
current interpreter. I believe, though, that NULL is never passed
here, and I think it's simpler to just remove this function and
require callers to be more explicit.

This patch fixes tagged pointer support for AArch64 GDB. Linux kernel
debugging failure was reported after tagged pointer support was committed.
After a discussion around best path forward to manage tagged pointers
on GDB side we are going to disable tagged pointers support for
aarch64-none-elf-gdb because for non-linux applications we cant be
sure if tagged pointers will be used by MMU or not.
Also for aarch64-linux-gdb we are going to sign extend user-space
address after clearing tag bits. This will help debug both kernel
and user-space addresses based on information from linux kernel
documentation given below:
According to AArch64 memory map:
https://www.kernel.org/doc/Documentation/arm64/memory.txt
"User addresses have bits 63:48 set to 0 while the kernel addresses have
the same bits set to 1."
According to AArch64 tagged pointers document:
https://www.kernel.org/doc/Documentation/arm64/tagged-pointers.txt
The kernel configures the translation tables so that translations made
via TTBR0 (i.e. userspace mappings) have the top byte (bits 63:56) of
the virtual address ignored by the translation hardware. This frees up
this byte for application use.
Running gdb testsuite after applying this patch introduces no regressions
and tagged pointer test cases still pass.
