all_match is write only, though:
+ bool all_match = true;
+ unsigned int i, j;
+
+ gcc_assert (have_regs_of_mode[m]);
+ for (i = 0; i < N_REG_CLASSES; i++)
+ if (contains_reg_of_mode[i][m])
+ for (j = 0; j < N_REG_CLASSES; j++)
+ {
+ int cost;
+ if (!contains_reg_of_mode[j][m])
+ cost = 65535;
+ else
+ {
+ cost = REGISTER_MOVE_COST (m, i, j);
+ gcc_assert (cost < 65535);
+ }
+ all_match &= (last_move_cost[i][j] == cost);
