◆ getRunCondition()

isl::ast_expr IslAstInfo::getRunCondition ( )

Get the run condition.

Only if the run condition evaluates at run-time to a non-zero value, the assumptions that have been taken hold. If the run condition evaluates to zero/false some assumptions do not hold and the original code needs to be executed.
