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.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs.html for how to report bugs usefully.
