[4.8, 4.9] Backport of additional SLM tuning.
Six patches from trunk, reg-tested via 'make check': 2014-05-07 Evgeny Stupachenko <evstupac@gmail.com> * tree-vect-data-refs.c (vect_grouped_load_supported): New check for loads group of length 3. (vect_permute_load_chain): New permutations for loads group of length 3. * tree-vect-stmts.c (vect_model_load_cost): Change cost of vec_perm_shuffle for the new permutations. 2014-04-17 Evgeny Stupachenko <evstupac@gmail.com> * config/i386/i386.c (x86_add_stmt_cost): Fix vector cost model for Silvermont. 2014-04-17 Evgeny Stupachenko <evstupac@gmail.com> * config/i386/x86-tune.def (TARGET_SLOW_PSHUFB): New tune definition. * config/i386/i386.h (TARGET_SLOW_PSHUFB): New tune flag. * config/i386/i386.c (expand_vec_perm_even_odd_1): Avoid byte shuffles for TARGET_SLOW_PSHUFB 2014-04-17 Evgeny Stupachenko <evstupac@gmail.com> * config/i386/i386.c (slm_cost): Adjust vec_to_scalar_cost. * config/i386/i386.c (intel_cost): Ditto. 2014-06-18 Evgeny Stupachenko <evstupac@gmail.com> * config/i386/i386.c (ix86_reassociation_width): Add alternative for vector case. * config/i386/i386.h (TARGET_VECTOR_PARALLEL_EXECUTION): New. * config/i386/x86-tune.def (X86_TUNE_VECTOR_PARALLEL_EXECUTION): New. * tree-vect-data-refs.c (vect_shift_permute_load_chain): New. Introduces alternative way of loads group permutaions. (vect_transform_grouped_load): Try alternative way of permutations. 2014-06-05 Evgeny Stupachenko <evstupac@gmail.com> * config/i386/sse.md (*ssse3_palignr<mode>_perm): New. * config/i386/predicates.md (palignr_operand): New. Indicates if permutation is suitable for palignr instruction. Change-Id: I5e505735ce3dc0ec3c2a1151713a119b24d712fe Signed-off-by: Alexander Ivchenko <alexander.ivchenko@intel.com>
