target.h (builtin_vectorization_cost): Add new target builtin.
2007-07-12 Dorit Nuzman <dorit@il.ibm.com> * target.h (builtin_vectorization_cost): Add new target builtin. * target-def.h (TARGET_VECTORIZE_BUILTIN_VECTORIZATION_COST): New. * tree-vectorizer.h (TARG_SCALAR_STMT_COST): New. (TARG_SCALAR_LOAD_COST, TARG_SCALAR_STORE_COST): New. * tree-vect-analyze.c (vect_analyze_slp_instance): Initisliaze uninitialized variables. * tree-vect-transform.c (cost_for_stmt): New function. (vect_estimate_min_profitable_iters): Call cost_for_stmt instead of using cost 1 for all scalar stmts. Be less conservative when estimating the number of prologue/epulogue iterations. Call targetm.vectorize.builtin_vectorization_cost. Return min_profitable_iters-1. (vect_model_reduction_cost): Use TARG_SCALAR_TO_VEC_COST for initialization cost instead of TARG_VEC_STMT_COST. Use TARG_VEC_TO_SCALAR_COST instead of TARG_VEC_STMT_COST for reduction epilogue code. Fix epilogue cost computation. * config/spu/spu.c (spu_builtin_vectorization_cost): New. (TARGET_VECTORIZE_BUILTIN_VECTORIZATION_COST): Implement. * config/spu/spu.h (TARG_COND_BRANCH_COST, TARG_SCALAR_STMT_COST): (TARG_SCALAR_LOAD_COST, TARG_SCALAR_STORE_COST, TARG_VEC_STMT_COST): (TARG_VEC_TO_SCALAR_COST, TARG_SCALAR_TO_VEC, TARG_VEC_LOAD_COST): (TARG_VEC_UNALIGNED_LOAD_COST, TARG_VEC_STORE_COST): Define. 2007-07-12 Dorit Nuzman <dorit@il.ibm.com> * gcc.dg/vect/costmodel/ppc/costmodel-vect-reduc-1char.c: Loops now get vectorized. * gcc.dg/vect/costmodel/i386/costmodel-vect-reduc-1char.c: Loops now get vectorized. * gcc.dg/vect/costmodel/spu/spu-costmodel-vect.exp: New. * gcc.dg/vect/costmodel/spu/costmodel-fast-math-vect-pr29925.c: New. * gcc.dg/vect/costmodel/spu/costmodel-vect-31a.c: New. * gcc.dg/vect/costmodel/spu/costmodel-vect-31b.c: New. * gcc.dg/vect/costmodel/spu/costmodel-vect-31c.c: New. * gcc.dg/vect/costmodel/spu/costmodel-vect-31d.c: New. * gcc.dg/vect/costmodel/spu/costmodel-vect-iv-9.c: New. * gcc.dg/vect/costmodel/spu/costmodel-vect-33.c: New. * gcc.dg/vect/costmodel/spu/costmodel-vect-76a.c: New. * gcc.dg/vect/costmodel/spu/costmodel-vect-76b.c: New. * gcc.dg/vect/costmodel/spu/costmodel-vect-76c.c: New. * gcc.dg/vect/costmodel/spu/costmodel-vect-68a.c: New. * gcc.dg/vect/costmodel/spu/costmodel-vect-68b.c: New. * gcc.dg/vect/costmodel/spu/costmodel-vect-68c.c: New. * gcc.dg/vect/costmodel/spu/costmodel-vect-68d.c: New. * lib/target-supports.exp (check_effective_target_vect_int_mul): Add spu.
