2011-07-28Fix PR48648: Handle CLAST assignments.Sebastian Pop4-0/+79
The CLAST produced by CLooG-ISL contains an assignment and GCC chokes on it. The exact CLAST contains an assignment followed by an if: scat_1 = max(0,ceild(T_4-7,8)); if (scat_1 <= min(1,floord(T_4-1,8))) { S7(scat_1); } This is equivalent to a loop that iterates only once, and so CLooG generates an assignment followed by an if instead of a loop. This is an important optimization that was improved in ISL, that allows if-conversion: imagine GCC having to figure out that a loop like the following actually iterates only once, and can be converted to an if: for (scat_1 = max(0,ceild(T_4-7,8)); scat_1 <= min(1,floord(T_4-1,8)); scat_1++) S7(scat_1); This patch implements the translation of CLAST assignments.
