This fixes all the straightforward -Wshadow=local warnings in gdb. A
few standard approaches are used here:
* Renaming an inner (or outer, but more commonly inner) variable;
* Lowering a declaration to avoid a clash;
* Moving a declaration into a more inner scope to avoid a clash,
including the special case of moving a declaration into a loop header.
I did not consider any of the changes in this patch to be particularly
noteworthy, though of course they should all still be examined.

I noticed a couple of unnecessary casts in cli-cmds.c. This patch
removes them.
Tested by rebuilding. I'm checking this in.

This patch adds support for disassembly of blocks with non-contiguous
ranges. These blocks are printed as follows:
(gdb) disassemble foo
Dump of assembler code for function foo:
Address range 0x401136 to 0x401151:
0x0000000000401136 <+0>: push %rbp
0x0000000000401137 <+1>: mov %rsp,%rbp
0x000000000040113a <+4>: callq 0x401134 <bar>
0x000000000040113f <+9>: mov 0x2eef(%rip),%eax # 0x404034 <e>
0x0000000000401145 <+15>: test %eax,%eax
0x0000000000401147 <+17>: je 0x40114e <foo+24>
0x0000000000401149 <+19>: callq 0x401128 <foo+4294967282>
0x000000000040114e <+24>: nop
0x000000000040114f <+25>: pop %rbp
0x0000000000401150 <+26>: retq
Address range 0x401128 to 0x401134:
0x0000000000401128 <+-14>: push %rbp
0x0000000000401129 <+-13>: mov %rsp,%rbp
0x000000000040112c <+-10>: callq 0x401126 <baz>
0x0000000000401131 <+-5>: nop
0x0000000000401132 <+-4>: pop %rbp
0x0000000000401133 <+-3>: retq
End of assembler dump.
This is an actual dump from the test case that I constructed for
this work. The ranges are printed in the order encountered in the
debug info. For the above example, note that the second range occupies
lower addresses than the first range.
Functions with contiguous ranges are still printed as follows:
(gdb) disassemble main
Dump of assembler code for function main:
0x0000000000401151 <+0>: push %rbp
0x0000000000401152 <+1>: mov %rsp,%rbp
0x0000000000401155 <+4>: callq 0x401136 <foo>
0x000000000040115a <+9>: mov $0x0,%eax
0x000000000040115f <+14>: pop %rbp
0x0000000000401160 <+15>: retq
End of assembler dump.

* cli/cli-cmds.c (block.h): Include.
(print_disassembly): Handle printing of non-contiguous blocks.
(disassemble_current_function): Likewise.

I happened to notice recently that "gdb --version" says:

For help, type "help".
Type "apropos word" to search for commands related to "word".
This is a bit on the wordy side, but also references interactive
commands, which I think doesn't really make sense for --version.
This patch removes some text from --version, while leaving it in the
"show version" output. It also adds a newline between the URLs and
the "For help, ..." text, because I thought that was easier to read.
Finally, it indents one of the URLs, since that was simpler to read,
but not the other URL, because the current format is specified by the
GNU coding standards section on "--version".
Now the --version output looks like:

This patch constifies add_info and updates all the info commands. The
bulk of this patch was written using a script; and then I did a manual
pass to fix up the remaining compilation errors.
I could not compile every changed file; in particular nto-procfs.c,
gnu-nat.c, and darwin-nat-info.c; but I at least tried to check the
correctness by inspection.

This changes add_com to take a cmd_const_cfunc_ftype, and then fixes

In most cases this is trivial.
In a couple of places I had to again introduce a temporary non-const
overload. These overloads will be removed when add_info is
constified.

The "x", "list", and "show commands" commands have special repetition
behavior: repeating the command doesn't re-run it with the same
arguments
This is currently implemented by modifying the passed-in argument; but
that won't work properly with const arguments (and seems pretty
obscure besides).
This patch adds a new "set_repeat_arguments" function and changes the
relevant places to call it.

This changes add_prefix_cmd to accept a const-taking function as an
argument; then fixes up all the callers.
In a couple of spots I had to add a non-const overload of a function,
because the function is passed to two different command-adding
"constructors". These overloads are temporary; once constification is
complete they can be removed.
This patch also fixes a typo I happened to notice while constifying.
Note that this touches a couple of files (gnu-nat.c and go32-nat.c)
that I can't build. So, while I made a best-effort there, I am not
certain they will still compile.
Tested by rebuilding.

While we still have cleanups (i.e., make_cleanup & co), we must be
sure to add END_CATCH at the end of a TRY/CATCH/END_CATCH construct.
However, it's currently too easy to miss adding the END_CATCH, because
the code compiles anyway without it. I realized this when I noticed
that another patch I was working on missed several adding END_CATCH in
several new TRY/CATCH uses.
This commit fixes that by making TRY open a new scope that is only
closed by END_CATCH. This way, if you forget to add the END_CATCH,
then compilation fails due to the unbalanced curly braces.
This caught a couple places where we were missing END_CATCH in current
master, also fixed by the patch.

This commit adds new "set/show cwd" commands, which are used to
set/show the current working directory of the inferior that will be
started.
The idea here is that "set cwd" will become the de facto way of
setting the inferior's cwd. Currently, the user can use "cd" for
that, but there are side effects: with "cd", GDB also switches to
another directory, and that can impact the loading of scripts and
other files. With "set cwd", we separate the logic into a new
command.
To maintain backward compatibility, if the user issues a "cd" command
but doesn't use "set cwd", then the inferior's cwd will still be
changed according to what the user specified. However, "set cwd" has
precedence over "cd", so it can always be used to override it.
"set cwd" works in the following way:
- If the user sets the inferior's cwd by using "set cwd", then this
directory is saved into current_inferior ()->cwd and is used when
the inferior is started (see below).
- If the user doesn't set the inferior's cwd by using "set cwd", but
rather use the "cd" command as before, then this directory is
inherited by the inferior because GDB will have chdir'd into it.
On Unix-like hosts, the way the directory is changed before the
inferior execution is by expanding the user set directory before the
fork, and then "chdir" after the call to fork/vfork on
"fork_inferior", but before the actual execution. On Windows, the
inferior cwd set by the user is passed directly to the CreateProcess
call, which takes care of the actual chdir for us.
This way, we'll make sure that GDB's cwd is not affected by the user
set cwd.

This adds two add_cmd overloads: one whose callback takes a const char *,
and one that doesn't accept a function at all. The no-function overload
was introduced to avoid ambiguity when NULL was passed as the function.
Long term the goal is for all commands to take const arguments, and
for the non-const variants to be removed entirely.

Currently we have "current_directory" and "gdb_dirbuf" globals, which
means that we basically have two possible places to consult when we
want to know GDB's current working directory.
This is not ideal and can lead to confusion. Moreover, the way we're
using "gdb_difbuf" along with "getcwd" is problematic because we
declare the buffer with "1024" elements hardcoded, which does not take
into account longer pathnames that are possible in many filesystems.
Using "PATH_MAX" would also not be a solution because of portability
problems. Therefore, the best solution is to rely on the fact that
"getcwd (NULL, 0)" will "do the right thing" and return a
heap-allocated string containing the full path. With the new "getcwd"
module from gnulib, it is now possible to do that without worrying
about breaking some host.
With this patch "current_directory" is now the only place to check for
GDB's cwd.

Currently, with an ambiguous "list first,last", we get:
(gdb) list bar,main
Specified first line 'bar' is ambiguous:
file: "src/gdb/testsuite/gdb.cp/overload.cc", line number: 97
file: "src/gdb/testsuite/gdb.cp/overload.cc", line number: 98
This commit makes gdb's output above a bit clearer by printing the
symbol name as well:
(gdb) list bar,main
Specified first line 'bar' is ambiguous:
file: "src/gdb/testsuite/gdb.cp/overload.cc", line number: 97, symbol: "bar(A)"
file: "src/gdb/testsuite/gdb.cp/overload.cc", line number: 98, symbol: "bar(B)"
And while at it, makes gdb print the symbol name when actually listing
multiple locations too. I.e., before (with "set listsize 2"):
(gdb) list bar
file: "src/gdb/testsuite/gdb.cp/overload.cc", line number: 97
96
97 int bar (A) { return 11; }
file: "src/gdb/testsuite/gdb.cp/overload.cc", line number: 98
97 int bar (A) { return 11; }
98 int bar (B) { return 22; }
After:
(gdb) list bar
file: "src/gdb/testsuite/gdb.cp/overload.cc", line number: 97, symbol: "bar(A)"
96
97 int bar (A) { return 11; }
file: "src/gdb/testsuite/gdb.cp/overload.cc", line number: 98, symbol: "bar(B)"
97 int bar (A) { return 11; }
98 int bar (B) { return 22; }
Currently, the result of decoding a linespec loses information about
the original symbol that was found. All we end up with is an address.
This makes it difficult to find the original symbol again to get at
its print name. Fix that by storing a pointer to the symbol in the
sal. We already store the symtab and obj_section, so it feels like a
natural progression to me. This avoids having to do any extra symbol
lookup too.

This renames a few functions -- skip_spaces_const,
skip_to_space_const, get_number_const, extract_arg_const -- to drop
the "_const" suffix and instead rely on overloading.
This makes future const fixes simpler by reducing the number of lines
that must be changed. I think it is also not any less clear, as all
these functions have the same interface as their non-const versions by
design. Furthermore there's an example of using an overload in-tree
already, namely check_for_argument.
This patch was largely created using some perl one-liners; then a few
fixes were applied by hand.

For some reason I ended up staring at some of the "int flags" in
btrace-related code, and I got confused because I had no clue what the
flags where supposed to indicate.
Fix that by using enum_flags, so that:
#1 - it's clear from the type what the flags are about, and
#2 - the compiler can catch mismatching mistakes

Instead, make symtab_and_line initialize its members itself. Many
symtab_and_line declarations are moved to where the object is
initialized at the same time both for clarity and to avoid double
initialization. A few functions, like e.g., find_frame_sal are
adjusted to return the sal using normal function return instead of an
output parameter likewise to avoid having to default-construct a sal
and then immediately have the object overwritten.

This replaces "struct symtabs_and_lines" with
std::vector<symtab_and_line> in most cases. This removes a number of
cleanups.
In some cases, the sals objects do not own the sals they point at.
Instead they point at some sal that lives on the stack. Typically
something like this:
struct symtab_and_line sal;
struct symtabs_and_lines sals;
// fill in sal
sals.nelts = 1;
sals.sals = &sal;
// use sals
Instead of switching those cases to std::vector too, such usages are
replaced by gdb::array_view<symtab_and_line> instead. This avoids
introducing heap allocations.

Currently, with "list LINESPEC1,LINESPEC2", if one of the linespecs is
ambiguous, i.e., if it expands to multiple locations, you get this
seemingly odd output:
(gdb) list foo,bar
file: "file0.c", line number: 26
file: "file1.c", line number: 29
Since "foo" above expands to multiple locations, the specified range
is indeterminate, and GDB is trying to be helpful by showing you what
was ambiguous. It looks confusing to me, though. I think it'd be
much more user friendly if GDB actually told you that, like this:
(gdb) list foo,bar
Specified first line 'foo' is ambiguous:
file: "file0.c", line number: 26
file: "file1.c", line number: 29
(gdb) list bar,foo
Specified last line 'foo' is ambiguous:
file: "file0.c", line number: 26
file: "file1.c", line number: 29
Note, I'm using "first" and "last" in the output because that's what
the manual uses:
~~~
list first,last
Print lines from first to last. [...]
~~~
Tested on x86-64 GNU/Linux.

file: "overload.cc", line number: 1
file: "overload.cc", line number: 2
It would be better for GDB to list the actual code around those two
locations, not just print the location. Like:
(gdb) list bar
file: "overload.cc", line number: 1
1 int bar() { return 0;}
2 int bar(int) { return 0; }
file: "overload.cc", line number: 2
1 int bar() { return 0;}
2 int bar(int) { return 0; }
That's what this this commit implements.
Tested on x86-64 GNU/Linux.

Now, GDB is able to dynamically create i386-linux target descriptions
from features, instead of using pre-generated target descriptions. These
pre-generated target descriptions are no longer used by GDB (note that
they are still used by GDBserver).

One of the most annoying (to me) things about GDB's completion is when
you have overloads in your program, and you want to set a breakpoint
in one of them:
void function(int); // set breakpoint here.
void function(long);
(gdb) b -f func[TAB]
(gdb) b -f function( # ok, gdb completed as much as possible.
(gdb) b -f function([TAB] # show me the overloads, please.
<_all_ symbols in the program are shown...>
E.g., when debugging GDB, that'd be:
(gdb) b -f function([TAB]
(anonymous namespace)::get_global()::global pt_insn_get_offset@plt scm_new_port_table_entry
asprintf pt_pkt_alloc_decoder scm_new_port_table_entry@plt
asprintf@plt pt_pkt_alloc_decoder@plt scm_out_of_range
bt_ctf_get_char_array pt_pkt_sync_forward scm_out_of_range@plt
bt_ctf_get_char_array@plt pt_pkt_sync_forward@plt scm_putc
bt_ctf_get_uint64 pwrite scm_putc@plt
bt_ctf_get_uint64@plt pwrite@plt scm_reverse_x
bt_ctf_iter_read_event PyErr_Restore scm_reverse_x@plt
bt_ctf_iter_read_event@plt PyErr_Restore@plt scm_set_port_filename_x
<snip...>
Now that's a load of completely useless completions.
The reason GDB offers those is that the completer relies on readline
figuring out the completion word point in the input line based on the
language's word break characters, which include "(". So readline
tells the completer to complete on "", the string that is after '('.
Likewise, if you type "function(i[TAB]" to try to complete to "int",
you're out of luck. GDB shows you all the symbols in the program that
start with "i"... This makes sense for the expression completer, as
what you'd want to type is e.g., a global variable, say:
(gdb) print function(i[TAB]
but, it makes no sense when specifying a function name for a
breakpoint location.
To get around that limitation, users need to quote the function name,
like:
(gdb) b -f 'function([TAB]
function(int) function(long)
(gdb) b 'function(i[TAB]
(gdb) b 'function(int)' # now completes correctly!
Note that the quoting is only necessary for completion. Creating the
breakpoint does not require the quoting:
(gdb) b -f function(int) [RET]
Breakpoint 1 at ....
This patch removes this limitation.
(
Actually, it's a necessary patch, though not sufficient. That'll
start working correctly by the end of the series. With this patch, if try it,
you'll see:
(gdb) b -f function(i[TAB]
(gdb) b -f function
i.e., gdb strips everything after the "(". That's caused by some code
in symtab.c that'll be eliminated further down the series. These
patches are all unfortunately interrelated, which is also the reason
new tests only appear much later in the series.
But let's ignore that reality for the remainder of the description.
)
So... this patch gets rid of the need for quoting.
It does that by adding a way for a completer to control the exact
completion word point that readline should start the completion
request for, instead of letting readline try to figure it out using
the current language's word break chars array, and often failing.
In the case above, we want the completer to figure out that it's
completing a function name that starts with "function(i". It now
does.
It took me a while to figure out a way to ask readline to "use this
exact word point", and for a while I feared that it'd be impossible
with current readline (and having to rely on master readline for core
functionality is something I'd like to avoid very much). Eventually,
after several different attempts, I came up with what is described in
the comment above gdb_custom_word_point_brkchars in the patch.
With this patch, the handle_brkchars phase of the explicit location
completer advances the expected word point as it parses the input line
left to right, until it figures out exactly what we're completing,
instead of expecting readline to break the string using the word break
characters, and then having the completer heuristically fix up a bad
decision by parsing the input string backwards. This allows correctly
knowning that we're completing a symbol name after -function, complete
functions without quoting, etc.
Later, we'll make use of this same mechanims to implement a proper
linespec completer that avoids need for quoting too.

The linespec/locations/completer testcase added later in the series
tests every completion with both TAB completion and the "complete"
command. This exposed problems in the "complete" command, around
determining the completion word point.
First, the complete command has a too-simple approximation of what
readline's TAB-completion code does to find the completion word point.
Unfortunately, readline doesn't expose the functionality it uses
internally, so to fix this this patch copies over the relevant code,
and adjusts it a bit to better fit the use cases we need it for.
(Specifically, our version avoids relying on the
rl_word_break_characters, etc. globals, and instead takes those as
arguments.)
A following patch will want to use this function for TAB-completion
too, but the "complete" command was a good excuse to split this to a
separate patch.
Then, notice how the complete_command does not call into the completer
for the command being completed to determine the right set of word
break characters. It always uses the default set. That is fixed by
having the "complete" command call into complete_line_internal for a
full handle_brkchars phase, just TAB-completion.

This patch reworks the whole completion machinery, and prepares it
for later enhancements.
Adds a new "completion_tracker" class that is meant to hold everything
about the state of the current completion operation.
This class now has the responsibility of tracking the list of
completion matches, and checking whether the max completions limit has
been reached. You can look at this as this patch starting out by
C++fying the existing "completion_tracker" in symtab.c (it's just an
htab_t typedef currently), moving it to completer.h/c, and then making
it a class/generalizing/enhancing it.
Unlike with the current tracking, completion_tracker now checks
whether the limit has been reached on each completion match list
insertion. This both simplifies the max-completions handling code
(maybe_add_completion_enum is gone, for example), and is a
prerequisite for follow up patches.
The current completion_tracker is only used for symbol completions,
and the symbol code gets at the current instance via globals. This
patch cleans that up by adding a completion_tracker reference to the
signature of the completion functions, and passing the tracker around
everywhere necessary.
Then, the patch changes how the completion match list is handed over
to readline. Currently, we're using the rl_completion_entry_function
readline entry point, and the patch switches to
rl_attempted_completion_function. A following patch will want to let
GDB itself decide the common completion prefix between all matches
(what readline calls the "lowest common denominator"), instead of
having readline compute it, and that's not possible with the
rl_completion_entry_function entry point. Also,
rl_attempted_completion_function lets GDB hand over the match list to
readline as an array in one go instead of passing down matches one by
one, so from that angle it's a nicer entry point anyway.
Lastly, the patch catches exceptions around the readline entry points,
because we can't let C++ exceptions cross readline. We handle that in
the readline input entry point, but the completion entry point isn't
guarded, so GDB can abort if completion throws. E.g., in current
master:
(gdb) b -function "fun<tab>
terminate called after throwing an instance of 'gdb_exception_RETURN_MASK_ERROR'
Aborted (core dumped)
This patch fixes that. This will be exercised in the new tests added
later on in the series.

This removes make_cleanup_delete_event_location and instead changes
the various location functions to return an event_location_up, a new
unique_ptr typedef.
This is largely straightforward, but be sure to examine the
init_breakpoint_sal change. I believe the code I deleted there is
dead, because "location != NULL" can never be true in that branch; but
you should double-check.

gdb/ChangeLog:
Update copyright year range in all GDB files.

This patch finalizes the C++ conversion of the ui-out subsystem, by
turning the ui_out and ui_out_impl structures into a single class
hierarchy. ui_out functions are turned into virtual methods of that new
class, so as a result there are a lot of call sites to update.
In the previous version of the patchset, there were separate ui_out and
ui_out_impl classes, but it wasn't really useful and added boilerplate.
In this version there is simply an ui_out base class that is
extended for CLI, TUI and MI.
It's a bit hard to maintain a ChangeLog for such a big patch, I did my
best but I'm sure there are some missing or outdated info in there...

This patch changes some code in cli-cmds.c to use std::string rather
than dyn-string, removing some cleanups. Since this was the last use
of dyn-string in gdb, this patch also removes
make_cleanup_dyn_string_delete.

This fixes PR gdb/20604. The bug here is that passing an invalid
expression to "quit" -- e.g., "quit()" -- causes gdb to enter a
non-functioning state.
The immediate problem is that quit_force resets the terminal before
evaluating the expression. However, it seemed to me that it doesn't
really make sense to pass the quit_force argument to kill_or_detach
(which passes it to to_detach), first because conflating the exit
status for "quit" and the signal to pass when detaching doesn't make
sense, and second because to_detach implementations generally only
accept a constant here, while "quit" accepts an expression. So, I
removed that.
As an aside, I think the "detach SIGNO" functionality is not
documented.
Built and regtested on x86-64 Fedora 24.

Currently, we always re-set all locations of all breakpoints. This
commit makes us re-set only locations of the current program space.
If we loaded symbols to a program space (e.g., "file" command or some
shared library was loaded), GDB must run through all breakpoints and
determine if any new locations need to be added to the breakpoint.
However, there's no reason to recreate locations for _other_ program
spaces, as those haven't changed.
Similarly, when we create a new inferior, through e.g., a fork, GDB
must run through all breakpoints and determine if any new locations
need to be added to the breakpoint. There's no reason to destroy the
locations of the parent inferior and other inferiors. We know those
won't change.
In addition to being inneficient, resetting breakpoints of inferiors
that are currently running is problematic, because:
- some targets can't read memory while the inferior is running.
- the inferior might exit while we're re-setting its breakpoints,
which may confuse prologue skipping.
I went through all the places where we call breakpoint_re_set, and it
seems to me that all can be changed to only re-set locations of the
current program space.
The patch that reversed threads order in "info threads" etc. happened
to make gdb.threads/fork-plus-thread.exp expose this problem when
testing on x86/-m32. The problem was latent and masked out by chance
by the code-cache:
https://sourceware.org/ml/gdb-patches/2016-01/msg00213.html
Tested on x86-64 F20, native (-m64/-m32) and extended-remote
gdbserver.
Fixes the regression discussed in the url above with --target_board=unix/-m32:
-FAIL: gdb.threads/fork-plus-threads.exp: detach-on-fork=off: inferior 1 exited
+PASS: gdb.threads/fork-plus-threads.exp: detach-on-fork=off: inferior 1 exited
-FAIL: gdb.threads/fork-plus-threads.exp: detach-on-fork=off: no threads left (timeout)
-FAIL: gdb.threads/fork-plus-threads.exp: detach-on-fork=off: only inferior 1 left (the program exited)
+PASS: gdb.threads/fork-plus-threads.exp: detach-on-fork=off: no threads left
+PASS: gdb.threads/fork-plus-threads.exp: detach-on-fork=off: only inferior 1 left
