Informally, a loop is P-solvable if the following conditions are satisfied: (i) the loop body consists only of nested conditionals and assignments, (ii) assignments to scalars form a linear recurrence system with constant coefficients, (iii) closed forms of scalar variables can be represented by a polynomial system over loop counters and some extra variables where there are polynomial relations among the extra variables, and (iii) updates to arrays can be handled as uninterpreted functions over array and scalar variables.
