-Subject: [PATCH 23/54] [Patch] OPT: Update heuristics for loop-invariant for
- address arithme. .tic.
-
-The changes are made in the patch to update the heuristics
-for loop invariant for address arithmetic. The heuristics is
-changed to calculate the estimated register pressure cost when
-ira based register pressure is not enabled. The estimated
-register pressure cost modifies the existing calculation cost
-associated to perform the Loop invariant code motion for address
-arithmetic.

- * loop-invariant.c (gain_for_invariant): update the
- heuristics for estimate_reg_pressure_cost.
