[PATCH 2/5] Move vec to common/


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.

gdb:

2012-03-16  Yao Qi  <yao@codesourcery.com>

	* Makefile.in (SFILES): Add common/vec.c and remove vec.c.
	(vec.o): New rule.
	* vec.c: Move it ...
	* common/vec.c: ... here.
	* vec.h: Move it ...
	* common/vec.h: ... here.

gdb/gdbserver:

2012-03-16  Yao Qi  <yao@codesourcery.com>

	* Makefile.in (SFILES): Add common/vec.c.
	(OBS): Add vec.o.
	(vec.o): New rule.

+/* 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 }
