To: gdb-patches
ITSET need a type `struct inferior' to represent a process. Its counter part
in GDBserver is `struct process_info'. This patch is to rename `struct process_info'
to `struct inferior', so that ITSET code in gdb/common can use 'struct inferior'
unconditionally.
gdb/gdbserver:
* inferiors.c (struct process_info): Renamed to struct inferior.
* linux-arm-low.c, linux-low.c, linux-low.h: Update usage.
* linux-x86-low.c, lynx-low.c, mem-break.c, mem-break.h: Likewise.
* nto-low.c, remote-utils.c, server.c, server.h: Likewise.
* spu-low.c, target.h, thread-db.c, win32-low.c: Likewise.

ITSET is using vec, so when moving ITSET bits to gdb/common/, it is
straightforward to move vec.c and vec.h to gdb/common as well.

+/* 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 }
+

-/* 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 }
