Hello Richard:
With the below decison making I get the performance at par with trunk
changes and better than trunk for FP and INT SPEC 2017 benchmarks.
int best_bb_liveout_cnt
= bitmap_count_bits (&live->liveout[best_bb->index]);
int early_bb_liveout_cnt
= bitmap_count_bits (&live->liveou
Hello Richard:
Below are the performance numbers on CPU 2017 benchmarks with and without
register pressure
changes for code sinking.
INT Benchmarks:
With register pressure code sinking changes:

Hello All:
Currently code sinking heuristics are based on profile data like
basic block count and sink frequency threshold. We have removed
such heuristics and added register pressure heuristics based on
live-in and live-out of early blocks and immediate dominator of
use blocks of the same loop ne
