-
-#include "traits.h"
-#include <type_traits>
-
-/* 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. */

- foo (1, 2, {values, (size_t) nargs});

- 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.
-

- 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. */

-
- 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.

-/* The macros here implement a set of templated vector types and
- associated interfaces. These templates are implemented with
- macros, as we're not in C++ land. The interface functions are
- typesafe and use static inline functions, sometimes backed by
- out-of-line generic functions.
-
- Because of the different behavior of structure objects, scalar
- objects and of pointers, there are three flavors, one for each of
- these variants. Both the structure object and pointer variants
- pass pointers to objects around -- in the former case the pointers
- are stored into the vector and in the latter case the pointers are
- dereferenced and the objects copied into the vector. The scalar
- object variant is suitable for int-like objects, and the vector
- elements are returned by value.
-
- There are both 'index' and 'iterate' accessors. The iterator
- returns a boolean iteration condition and updates the iteration
- variable passed by reference. Because the iterator will be
- inlined, the address-of can be optimized away.
-
- The vectors are implemented using the trailing array idiom, thus
- they are not resizeable without changing the address of the vector
- object itself. This means you cannot have variables or fields of
- vector type -- always use a pointer to a vector. The one exception
- is the final field of a structure, which could be a vector type.
- You will have to use the embedded_size & embedded_init calls to
- create such objects, and they will probably not be resizeable (so
- don't use the 'safe' allocation variants). The trailing array
- idiom is used (rather than a pointer to an array of data), because,
- if we allow NULL to also represent an empty vector, empty vectors
- occupy minimal space in the structure containing them.
-
- Each operation that increases the number of active elements is
- available in 'quick' and 'safe' variants. The former presumes that
- there is sufficient allocated space for the operation to succeed
- (it dies if there is not). The latter will reallocate the
- vector, if needed. Reallocation causes an exponential increase in
- vector size. If you know you will be adding N elements, it would
- be more efficient to use the reserve operation before adding the
- elements with the 'quick' operation. This will ensure there are at
- least as many elements as you ask for, it will exponentially
- increase if there are too few spare slots. If you want reserve a
- specific number of slots, but do not want the exponential increase
- (for instance, you know this is the last allocation), use a
- negative number for reservation. You can also create a vector of a
- specific size from the get go.
-
- You should prefer the push and pop operations, as they append and
- remove from the end of the vector. If you need to remove several
- items in one go, use the truncate operation. The insert and remove
- operations allow you to change elements in the middle of the
- vector. There are two remove operations, one which preserves the
- element ordering 'ordered_remove', and one which does not
- 'unordered_remove'. The latter function copies the end element
- into the removed slot, rather than invoke a memmove operation. The
- 'lower_bound' function will determine where to place an item in the
- array using insert that will maintain sorted order.
-
- If you need to directly manipulate a vector, then the 'address'
- accessor will return the address of the start of the vector. Also
- the 'space' predicate will tell you whether there is spare capacity
- in the vector. You will not normally need to use these two functions.
-
- Vector types are defined using a DEF_VEC_{O,P,I}(TYPEDEF) macro.
- Variables of vector type are declared using a VEC(TYPEDEF) macro.
- The characters O, P and I indicate whether TYPEDEF is a pointer
- (P), object (O) or integral (I) type. Be careful to pick the
- correct one, as you'll get an awkward and inefficient API if you
- use the wrong one. There is a check, which results in a
- compile-time warning, for the P and I versions, but there is no
- check for the O versions, as that is not possible in plain C.
-
- An example of their use would be,
-
- DEF_VEC_P(tree); // non-managed tree vector.
-
- struct my_struct {
- VEC(tree) *v; // A (pointer to) a vector of tree pointers.
- };
-
- struct my_struct *s;
-
- if (VEC_length(tree, s->v)) { we have some contents }
- VEC_safe_push(tree, s->v, decl); // append some decl onto the end
- for (ix = 0; VEC_iterate(tree, s->v, ix, elt); ix++)
- { do something with elt }

+
+/* 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
+ callable, you instead specialize it for a given cleanup function,
+ and the generated class automatically has a constructor with the
+ same interface as the cleanup function. forward_scope_exit
+ 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);

+ than can then be used like this:

+ longjmp_breakpoint_cleanup obj (thread);
+
+ // Blah, blah, blah...
+
+ 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?>>
+

+#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. */

+ - You can add/substract an integer to/from an offset, which gives

+/* The macros here implement a set of templated vector types and
+ associated interfaces. These templates are implemented with
+ macros, as we're not in C++ land. The interface functions are
+ typesafe and use static inline functions, sometimes backed by
+ out-of-line generic functions.
+
+ Because of the different behavior of structure objects, scalar
+ objects and of pointers, there are three flavors, one for each of
+ these variants. Both the structure object and pointer variants
+ pass pointers to objects around -- in the former case the pointers
+ are stored into the vector and in the latter case the pointers are
+ dereferenced and the objects copied into the vector. The scalar
+ object variant is suitable for int-like objects, and the vector
+ elements are returned by value.
+
+ There are both 'index' and 'iterate' accessors. The iterator
+ returns a boolean iteration condition and updates the iteration
+ variable passed by reference. Because the iterator will be
+ inlined, the address-of can be optimized away.
+
+ The vectors are implemented using the trailing array idiom, thus
+ they are not resizeable without changing the address of the vector
+ object itself. This means you cannot have variables or fields of
+ vector type -- always use a pointer to a vector. The one exception
+ is the final field of a structure, which could be a vector type.
+ You will have to use the embedded_size & embedded_init calls to
+ create such objects, and they will probably not be resizeable (so
+ don't use the 'safe' allocation variants). The trailing array
+ idiom is used (rather than a pointer to an array of data), because,
+ if we allow NULL to also represent an empty vector, empty vectors
+ occupy minimal space in the structure containing them.
+
+ Each operation that increases the number of active elements is
+ available in 'quick' and 'safe' variants. The former presumes that
+ there is sufficient allocated space for the operation to succeed
+ (it dies if there is not). The latter will reallocate the
+ vector, if needed. Reallocation causes an exponential increase in
+ vector size. If you know you will be adding N elements, it would
+ be more efficient to use the reserve operation before adding the
+ elements with the 'quick' operation. This will ensure there are at
+ least as many elements as you ask for, it will exponentially
+ increase if there are too few spare slots. If you want reserve a
+ specific number of slots, but do not want the exponential increase
+ (for instance, you know this is the last allocation), use a
+ negative number for reservation. You can also create a vector of a
+ specific size from the get go.
+
+ You should prefer the push and pop operations, as they append and
+ remove from the end of the vector. If you need to remove several
+ items in one go, use the truncate operation. The insert and remove
+ operations allow you to change elements in the middle of the
+ vector. There are two remove operations, one which preserves the
+ element ordering 'ordered_remove', and one which does not
+ 'unordered_remove'. The latter function copies the end element
+ into the removed slot, rather than invoke a memmove operation. The
+ 'lower_bound' function will determine where to place an item in the
+ array using insert that will maintain sorted order.
+
+ If you need to directly manipulate a vector, then the 'address'
+ accessor will return the address of the start of the vector. Also
+ the 'space' predicate will tell you whether there is spare capacity
+ in the vector. You will not normally need to use these two functions.
+
+ Vector types are defined using a DEF_VEC_{O,P,I}(TYPEDEF) macro.
+ Variables of vector type are declared using a VEC(TYPEDEF) macro.
+ The characters O, P and I indicate whether TYPEDEF is a pointer
+ (P), object (O) or integral (I) type. Be careful to pick the
+ correct one, as you'll get an awkward and inefficient API if you
+ use the wrong one. There is a check, which results in a
+ compile-time warning, for the P and I versions, but there is no
+ check for the O versions, as that is not possible in plain C.
+
+ An example of their use would be,
+
+ DEF_VEC_P(tree); // non-managed tree vector.
+
+ struct my_struct {
+ VEC(tree) *v; // A (pointer to) a vector of tree pointers.
+ };
+
+ struct my_struct *s;
+
+ if (VEC_length(tree, s->v)) { we have some contents }
+ VEC_safe_push(tree, s->v, decl); // append some decl onto the end
+ for (ix = 0; VEC_iterate(tree, s->v, ix, elt); ix++)
