In that case there are other reload related bits that are snarfing up time: % cumulative self self total time seconds seconds calls s/call s/call name 36.00 227.89 227.89 102804 0.00 0.01 find_equiv_reg 26.39 394.97 167.08 703271664 0.00 0.00 single_set_2 23.97 546.71 151.74 1749021956 0.00 0.00 true_regnum 3.01 565.78 19.07 162045491 0.00 0.00 subreg_regno_offset I'm not planning to look into this further. *** This bug has been marked as a duplicate of 17503 *** -- What |Removed |Added ---------------------------------------------------------------------------- Status|ASSIGNED |RESOLVED Component|rtl-optimization |c Resolution| |DUPLICATE http://gcc.gnu.org/bugzilla/show_bug.cgi?id=16834
