Walking basic blocks with FOR_EACH_BB_REVERSE gives: Only FOR_EACH_BB_REVERSE: Compressing live ranges: from 1742579 to 429746 - 24% pre_count 41106212, post_count 34376494 Compressing live ranges: from 1742569 to 63000 - 3% pre_count 40835340, post_count 11055747 FOR_EACH_BB_REVERSE + need_curr_point_incr: Compressing live ranges: from 726184 to 416529 - 57% pre_count 40743516, post_count 34376846 Compressing live ranges: from 726174 to 61840 - 8% pre_count 40472806, post_count 11055747 The combination of the two changes takes ~20s off the ~180s for "LRA create live ranges".
