[LLVMdev] Instruction Scheduling
Hi, guys,
I am comparing the performance of the default scheduler (seems to be
the one that minimizes register pressure) with no scheduler
(-pre-RA-sched=none), and I got these numbers. The ratio is
low_reg_pressure/none, that is, the lower the number, the better the
performance with low register pressure:
