-
-/* An array_view is an abstraction that provides a non-owning view
- over a sequence of contiguous objects.
-
- A way to put it is that array_view is to std::vector (and
- std::array and built-in arrays with rank==1) like std::string_view
- is to std::string.
-
- The main intent of array_view is to use it as function input
- parameter type, making it possible to pass in any sequence of
- contiguous objects, irrespective of whether the objects live on the
- stack or heap and what actual container owns them. Implicit
- construction from the element type is supported too, making it easy
- to call functions that expect an array of elements when you only
- have one element (usually on the stack). For example:
-
- struct A { .... };
- void function (gdb::array_view<A> as);
-
- std::vector<A> std_vec = ...;
- std::array<A, N> std_array = ...;
- A array[] = {...};
- A elem;
-
- function (std_vec);
- function (std_array);
- function (array);
- function (elem);
-
- Views can be either mutable or const. A const view is simply
- created by specifying a const T as array_view template parameter,
- in which case operator[] of non-const array_view objects ends up
- returning const references. Making the array_view itself const is
- analogous to making a pointer itself be const. I.e., disables
- re-seating the view/pointer.
-
- Since array_view objects are small (pointer plus size), and
- designed to be trivially copyable, they should generally be passed
- around by value.
-
- You can find unit tests covering the whole API in
- unittests/array-view-selftests.c. */

-/* A forward_scope_exit is like scope_exit, but instead of giving it a

- captures the arguments passed to the ctor, and in turn passes those
- as arguments to the wrapped cleanup function, when it is called at
- scope exit time, from within the forward_scope_exit dtor. The
- forward_scope_exit class can take any number of arguments, and is
- cancelable if needed.
-
- This allows usage like this:
-
- void
- delete_longjmp_breakpoint (int arg)
- {
- // Blah, blah, blah...
- }
-
- using longjmp_breakpoint_cleanup
- = FORWARD_SCOPE_EXIT (delete_longjmp_breakpoint);

-
- obj.release (); // Optional cancel if needed.

- gdb::optional<longjmp_breakpoint_cleanup> cleanup;
- if (some condition)
- cleanup.emplace (thread);
- ...
- if (cleanup)

-
- since with scope exit, you would have to know the scope_exit's
- callable template type when you create the gdb::optional:
-
- gdb:optional<scope_exit<what goes here?>>
-

- exit time, and can also be used to "forward declare"

-#ifndef COMMON_FUNCTION_VIEW_H
-#define COMMON_FUNCTION_VIEW_H
-
-/* function_view is a polymorphic type-erasing wrapper class that
- encapsulates a non-owning reference to arbitrary callable objects.
-
- A way to put it is that function_view is to std::function like
- std::string_view is to std::string. While std::function stores a
- type-erased callable object internally, function_view holds a
- type-erased reference to an external callable object.
-
- This is meant to be used as callback type of a function that:
-
- #1 - Takes a callback as parameter.
-
- #2 - Wants to support arbitrary callable objects as callback type
- (e.g., stateful function objects, lambda closures, free
- functions).
-
- #3 - Does not store the callback anywhere; instead the function
- just calls the callback directly or forwards it to some
- other function that calls it.
-
- #4 - Can't be, or we don't want it to be, a template function
- with the callable type as template parameter. For example,
- when the callback is a parameter of a virtual member
- function, or when putting the function template in a header
- would expose too much implementation detail.
-
- Note that the C-style "function pointer" + "void *data" callback
- parameter idiom fails requirement #2 above. Please don't add new
- uses of that idiom. I.e., something like this wouldn't work;
-
- typedef bool (iterate_over_foos_cb) (foo *f, void *user_data),
- void iterate_over_foos (iterate_over_foos_cb *callback, void *user_data);
-
- foo *find_foo_by_type (int type)
- {
- foo *found = nullptr;
-
- iterate_over_foos ([&] (foo *f, void *data)
- {
- if (foo->type == type)
- {
- found = foo;
- return true; // stop iterating
- }
- return false; // continue iterating
- }, NULL);
-
- return found;
- }
-
- The above wouldn't compile, because lambdas with captures can't be
- implicitly converted to a function pointer (because a capture means
- some context data must be passed to the lambda somehow).
-
- C++11 gave us std::function as type-erased wrapper around arbitrary
- callables, however, std::function is not an ideal fit for transient
- callbacks such as the use case above. For this use case, which is
- quite pervasive, a function_view is a better choice, because while
- function_view is light and does not require any heap allocation,
- std::function is a heavy-weight object with value semantics that
- generally requires a heap allocation on construction/assignment of
- the target callable. In addition, while it is possible to use
- std::function in such a way that avoids most of the overhead by
- making sure to only construct it with callables of types that fit
- std::function's small object optimization, such as function
- pointers and std::reference_wrapper callables, that is quite
- inconvenient in practice, because restricting to free-function
- callables would imply no state/capture/closure, which we need in
- most cases, and std::reference_wrapper implies remembering to use
- std::ref/std::cref where the callable is constructed, with the
- added inconvenience that std::ref/std::cref have deleted rvalue-ref
- overloads, meaning you can't use unnamed/temporary lambdas with
- them.
-
- Note that because function_view is a non-owning view of a callable,
- care must be taken to ensure that the callable outlives the
- function_view that calls it. This is not really a problem for the
- use case function_view is intended for, such as passing a temporary
- function object / lambda to a function that accepts a callback,
- because in those cases, the temporary is guaranteed to be live
- until the called function returns.
-
- Calling a function_view with no associated target is undefined,
- unlike with std::function, which throws std::bad_function_call.
- This is by design, to avoid the otherwise necessary NULL check in
- function_view::operator().
-
- Since function_view objects are small (a pair of pointers), they
- should generally be passed around by value.
-
- Usage:
-
- Given this function that accepts a callback:
-
- void
- iterate_over_foos (gdb::function_view<void (foo *)> callback)
- {
- for (auto &foo : foos)
- callback (&foo);
- }
-
- you can call it like this, passing a lambda as callback:
-
- iterate_over_foos ([&] (foo *f)
- {
- process_one_foo (f);
- });
-
- or like this, passing a function object as callback:
-
- struct function_object
- {
- void operator() (foo *f)
- {
- if (s->check ())
- process_one_foo (f);
- }
-
- // some state
- state *s;
- };
-
- state mystate;
- function_object matcher {&mystate};
- iterate_over_foos (matcher);
-
- or like this, passing a function pointer as callback:
-
- iterate_over_foos (process_one_foo);
-
- You can find unit tests covering the whole API in
- unittests/function-view-selftests.c. */

- And also, since they're implemented as "enum class" strong
- typedefs, they're still integers ABI-wise, making them a bit more
- efficient than wrapper structs on some ABIs.
-
- Some properties of offset types, loosely modeled on pointers:
-
- - You can compare offsets of the same type for equality and order.
- You can't compare an offset with an unrelated type.
-
- - You can add/substract an integer to/from an offset, which gives
- you back a shifted offset.
-
- - You can subtract two offsets of the same type, which gives you
- back the delta as an integer (of the enum class's underlying
- type), not as an offset type.
-
- - You can't add two offsets of the same type, as that would not
- make sense.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
+# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH. The drawback is that using absolute paths prevent a

+/* An array_view is an abstraction that provides a non-owning view
+ over a sequence of contiguous objects.
+
+ A way to put it is that array_view is to std::vector (and
+ std::array and built-in arrays with rank==1) like std::string_view
+ is to std::string.
+
+ The main intent of array_view is to use it as function input
+ parameter type, making it possible to pass in any sequence of
+ contiguous objects, irrespective of whether the objects live on the
+ stack or heap and what actual container owns them. Implicit
+ construction from the element type is supported too, making it easy
+ to call functions that expect an array of elements when you only
+ have one element (usually on the stack). For example:
+
+ struct A { .... };
+ void function (gdb::array_view<A> as);
+
+ std::vector<A> std_vec = ...;
+ std::array<A, N> std_array = ...;
+ A array[] = {...};
+ A elem;
+
+ function (std_vec);
+ function (std_array);
+ function (array);
+ function (elem);
+
+ Views can be either mutable or const. A const view is simply
+ created by specifying a const T as array_view template parameter,
+ in which case operator[] of non-const array_view objects ends up
+ returning const references. Making the array_view itself const is
+ analogous to making a pointer itself be const. I.e., disables
+ re-seating the view/pointer.
+
+ Since array_view objects are small (pointer plus size), and
+ designed to be trivially copyable, they should generally be passed
+ around by value.
+
+ You can find unit tests covering the whole API in
+ unittests/array-view-selftests.c. */

+\`configure' configures gdbsupport 1.0 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]

+ CXX C++ compiler command

+#ifndef COMMON_FUNCTION_VIEW_H
+#define COMMON_FUNCTION_VIEW_H
+
+/* function_view is a polymorphic type-erasing wrapper class that
+ encapsulates a non-owning reference to arbitrary callable objects.
+
+ A way to put it is that function_view is to std::function like
+ std::string_view is to std::string. While std::function stores a
+ type-erased callable object internally, function_view holds a
+ type-erased reference to an external callable object.
+
+ This is meant to be used as callback type of a function that:
+
+ #1 - Takes a callback as parameter.
+
+ #2 - Wants to support arbitrary callable objects as callback type
+ (e.g., stateful function objects, lambda closures, free
+ functions).
+
+ #3 - Does not store the callback anywhere; instead the function
+ just calls the callback directly or forwards it to some
+ other function that calls it.
+
+ #4 - Can't be, or we don't want it to be, a template function
+ with the callable type as template parameter. For example,
+ when the callback is a parameter of a virtual member
+ function, or when putting the function template in a header
+ would expose too much implementation detail.
+
+ Note that the C-style "function pointer" + "void *data" callback
+ parameter idiom fails requirement #2 above. Please don't add new
+ uses of that idiom. I.e., something like this wouldn't work;
+
+ typedef bool (iterate_over_foos_cb) (foo *f, void *user_data),
+ void iterate_over_foos (iterate_over_foos_cb *callback, void *user_data);
+
+ foo *find_foo_by_type (int type)
+ {
+ foo *found = nullptr;
+
+ iterate_over_foos ([&] (foo *f, void *data)
+ {
+ if (foo->type == type)
+ {
+ found = foo;
+ return true; // stop iterating
+ }
+ return false; // continue iterating
+ }, NULL);
+
+ return found;
+ }
+
+ The above wouldn't compile, because lambdas with captures can't be
+ implicitly converted to a function pointer (because a capture means
+ some context data must be passed to the lambda somehow).
+
+ C++11 gave us std::function as type-erased wrapper around arbitrary
+ callables, however, std::function is not an ideal fit for transient
+ callbacks such as the use case above. For this use case, which is
+ quite pervasive, a function_view is a better choice, because while
+ function_view is light and does not require any heap allocation,
+ std::function is a heavy-weight object with value semantics that
+ generally requires a heap allocation on construction/assignment of
+ the target callable. In addition, while it is possible to use
+ std::function in such a way that avoids most of the overhead by
+ making sure to only construct it with callables of types that fit
+ std::function's small object optimization, such as function
+ pointers and std::reference_wrapper callables, that is quite
+ inconvenient in practice, because restricting to free-function
+ callables would imply no state/capture/closure, which we need in
+ most cases, and std::reference_wrapper implies remembering to use
+ std::ref/std::cref where the callable is constructed, with the
+ added inconvenience that std::ref/std::cref have deleted rvalue-ref
+ overloads, meaning you can't use unnamed/temporary lambdas with
+ them.
+
+ Note that because function_view is a non-owning view of a callable,
+ care must be taken to ensure that the callable outlives the
+ function_view that calls it. This is not really a problem for the
+ use case function_view is intended for, such as passing a temporary
+ function object / lambda to a function that accepts a callback,
+ because in those cases, the temporary is guaranteed to be live
+ until the called function returns.
+
+ Calling a function_view with no associated target is undefined,
+ unlike with std::function, which throws std::bad_function_call.
+ This is by design, to avoid the otherwise necessary NULL check in
+ function_view::operator().
+
+ Since function_view objects are small (a pair of pointers), they
+ should generally be passed around by value.
+
+ Usage:
+
+ Given this function that accepts a callback:
+
+ void
+ iterate_over_foos (gdb::function_view<void (foo *)> callback)
+ {
+ for (auto &foo : foos)
+ callback (&foo);
+ }
+
+ you can call it like this, passing a lambda as callback:
+
+ iterate_over_foos ([&] (foo *f)
+ {
+ process_one_foo (f);
+ });
+
+ or like this, passing a function object as callback:
+
+ struct function_object
+ {
+ void operator() (foo *f)
+ {
+ if (s->check ())
+ process_one_foo (f);
+ }
+
+ // some state
+ state *s;
+ };
+
+ state mystate;
+ function_object matcher {&mystate};
+ iterate_over_foos (matcher);
+
+ or like this, passing a function pointer as callback:
+
+ iterate_over_foos (process_one_foo);
+
+ You can find unit tests covering the whole API in
+ unittests/function-view-selftests.c. */

+ Some properties of offset types, loosely modeled on pointers:
+
+ - You can compare offsets of the same type for equality and order.
+ You can't compare an offset with an unrelated type.
+
+ - You can add/substract an integer to/from an offset, which gives

+ - You can subtract two offsets of the same type, which gives you
+ back the delta as an integer (of the enum class's underlying
