--- Comment #5 from amker at gcc dot gnu.org --- Author: amker Date: Wed Oct 19 11:02:23 2016 New Revision: 241339 URL: https://gcc.gnu.org/viewcvs?rev=241339&root=gcc&view=rev Log: PR tree-optimization/78005 * tree-vect-loop-manip.c (vect_gen_prolog_loop_niters): Compute upper (included) bound for niters of prolog loop. (vect_gen_scalar_loop_niters): Change parameter VF to VFM1. Compute niters of scalar loop above which vectorized loop is preferred, as well as the upper (included) bound for the niters. (vect_do_peeling): Record niter bound for loops accordingly. gcc/testsuite PR tree-optimization/78005 * gcc.dg/vect/pr78005.c: New. * gcc.target/i386/l_fma_float_1.c: Revise test. * gcc.target/i386/l_fma_float_2.c: Ditto. * gcc.target/i386/l_fma_float_3.c: Ditto. * gcc.target/i386/l_fma_float_4.c: Ditto. * gcc.target/i386/l_fma_float_5.c: Ditto. * gcc.target/i386/l_fma_float_6.c: Ditto. * gcc.target/i386/l_fma_double_1.c: Ditto. * gcc.target/i386/l_fma_double_2.c: Ditto. * gcc.target/i386/l_fma_double_3.c: Ditto. * gcc.target/i386/l_fma_double_4.c: Ditto. * gcc.target/i386/l_fma_double_5.c: Ditto. * gcc.target/i386/l_fma_double_6.c: Ditto.
