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
__isl_give isl_map *isl_map_copy(__isl_keep isl_map *map);
__isl_give isl_union_map *isl_union_map_copy(
__isl_keep isl_union_map *umap);

+ void *isl_map_free(__isl_take isl_map *map);
void *isl_union_map_free(__isl_take isl_union_map *umap);
Other sets and relations can be constructed by starting
__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.

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,
