3.1.1.1 isl

#include <cloog/isl/cloog.h>
CloogState *cloog_isl_state_malloc(isl_ctx *ctx);

When using the isl backend, CLooG will internally create many isl objects. If the user creates any CLooG objects from isl objects (e.g., through cloog_domain_from_isl_set below), then the user needs to make sure that these isl objects live in the same isl_ctx as those created by CLooG internally. The best way to ensure this property is to pass the isl_ctx created by the user to CLooG by calling cloog_isl_state_malloc to create a CloogState. Note that this makes the created CloogState a user of the given isl_ctx, meaning that the CloogState needs to be freed before the isl_ctx is freed.
