At line 276, lra_assert (spill_class != NO_REGS); would trigger whenever execution reached here with spill_class equal to NO_REGS. Seems to me that would never happen. Because one of the conditions in the if statement right above it (line 265) catches spill_class == NO_REGS and causes the rest of the for loop to be skipped by executing continue in the consequent of the if. So lra_assert never sees spill_class == NO_REGS. That makes line 276 dead code, right?
Thanks. GT.
