__isl_give isl_space *isl_space_set_alloc(isl_ctx *ctx,
unsigned nparam, unsigned dim);
__isl_give isl_space *isl_space_copy(__isl_keep isl_space *space);

unsigned isl_space_dim(__isl_keep isl_space *space,

#include <isl/space.h>
int isl_space_is_params(__isl_keep isl_space *space);
int isl_space_is_set(__isl_keep isl_space *space);
+ int isl_space_is_map(__isl_keep isl_space *space);
+
+Spaces can be compared using the following functions:
+
+ #include <isl/space.h>
+ int isl_space_is_equal(__isl_keep isl_space *space1,
+ __isl_keep isl_space *space2);
+ int isl_space_is_domain(__isl_keep isl_space *space1,
+ __isl_keep isl_space *space2);
+ int isl_space_is_range(__isl_keep isl_space *space1,
+ __isl_keep isl_space *space2);
+
+C<isl_space_is_domain> checks whether the first argument is equal
+to the domain of the second argument. This requires in particular that
+the first argument is a set space and that the second argument
+is a map space.
It is often useful to create objects that live in the
same space as some other object. This can be accomplished
__isl_give isl_printer *isl_printer_to_file(isl_ctx *ctx,
FILE *file);
__isl_give isl_printer *isl_printer_to_str(isl_ctx *ctx);
- void isl_printer_free(__isl_take isl_printer *printer);
+ void *isl_printer_free(__isl_take isl_printer *printer);
__isl_give char *isl_printer_get_str(
__isl_keep isl_printer *printer);
Sets and relations can be converted to union sets and relations
using the following functions.
- __isl_give isl_union_map *isl_union_map_from_map(
- __isl_take isl_map *map);
+ __isl_give isl_union_set *isl_union_set_from_basic_set(
+ __isl_take isl_basic_set *bset);
+ __isl_give isl_union_map *isl_union_map_from_basic_map(
+ __isl_take isl_basic_map *bmap);
__isl_give isl_union_set *isl_union_set_from_set(
__isl_take isl_set *set);
+ __isl_give isl_union_map *isl_union_map_from_map(
+ __isl_take isl_map *map);
The inverse conversions below can only be used if the input
union set or relation is known to contain elements in exactly one
void isl_basic_set_free(__isl_take isl_basic_set *bset);
void *isl_set_free(__isl_take isl_set *set);
void *isl_union_set_free(__isl_take isl_union_set *uset);
- void isl_basic_map_free(__isl_take isl_basic_map *bmap);
+ void *isl_basic_map_free(__isl_take isl_basic_map *bmap);
void isl_map_free(__isl_take isl_map *map);
void *isl_union_map_free(__isl_take isl_union_map *umap);
__isl_give isl_map *isl_map_remove_divs(
__isl_take isl_map *map);
+It is also possible to only remove those divs that are defined
+in terms of a given range of dimensions or only those for which
+no explicit representation is known.
+
+ __isl_give isl_basic_set *
+ isl_basic_set_remove_divs_involving_dims(
+ __isl_take isl_basic_set *bset,

+ unsigned first, unsigned n);
+ __isl_give isl_set *isl_set_remove_divs_involving_dims(

+

+ __isl_take isl_set *set);
+ __isl_give isl_map *isl_map_remove_unknown_divs(
+ __isl_take isl_map *map);
+
To iterate over all the sets or maps in a union set or map, use
int isl_union_set_foreach_set(__isl_keep isl_union_set *uset,
Similarly, the following functions can be used to check whether
a given dimension is involved in any lower or upper bound.
- int isl_set_dim_has_lower_bound(__isl_keep isl_set *set,
+ int isl_set_dim_has_any_lower_bound(__isl_keep isl_set *set,
enum isl_dim_type type, unsigned pos);
- int isl_set_dim_has_upper_bound(__isl_keep isl_set *set,
+ int isl_set_dim_has_any_upper_bound(__isl_keep isl_set *set,
enum isl_dim_type type, unsigned pos);
The identifiers or names of the domain and range spaces of a set
__isl_give isl_basic_map *isl_basic_map_set_tuple_name(

To check whether two multiple affine expressions are
obviously equal to each other, use
__isl_give isl_local_space **ls);
__isl_give isl_pw_multi_aff *isl_pw_multi_aff_coalesce(
__isl_take isl_pw_multi_aff *pma);
