From c91e822398d80d51e7b0e0884fa3e8c7c32d6ae7 Mon Sep 17 00:00:00 2001 From: dorit Date: Tue, 17 Aug 2004 16:17:14 +0000 Subject: * tree-vectorizer.c: New File: loop vectorization on SSAed GIMPLE trees. * tree-vectorizer.h: New File: Same. * Makefile.in (tree-vectorizer.c, tree-vectorizer.h): Add new files. * common.opt (ftree-vectorize): New flag to enable vectorization. * timevar.def (TV_TREE_VECTORIZATION): New dump file for vectorization pass. * tree-data-ref.h (init_data_ref): Additional argument. (array_base_name_differ_p): Moved to tree-data-ref.c. * tree-data-ref.c (array_base_name_differ_p): Revised. (initialize_data_dependence_relation): Call array_base_name_differ_p with an extra argument. (analyze_all_data_dependences): Same. (init_data_ref): Additional argument is_read to set DR_IS_READ. * tree-ssa-phiopt.c (empty_block_p): Expose for usage out of this file. * tree-flow.h (vectorize_loops, empty_block_p): Add declaration. * tree-optimize.c (pass_vectorize): Schedule the vectorization pass. * tree-pass.h (tree_opt_pass pass_vectorize): Declare the new vectorization pass. * tree-ssa-loop.c (tree_ssa_loop_init): Call scev_initialize. (tree_ssa_loop_done): Call scev_finalize. (tree_vectorize): Define the new vectorization pass. * defaults.h (UNITS_PER_SIMD_WORD): Allow targets to specify the size of the vector they support (until support for multiple vector sizes is added to the vectorizer). * config/i386/i386.h (UNITS_PER_SIMD_WORD): Define. * config/rs6000/rs6000.h (UNITS_PER_SIMD_WORD): Define. * invoke.texi (fdump-tree-vect, ftree-vectorize): Add documentation. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@86131 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/testsuite/gcc.dg/vect/vect-18.c | 129 ++++++++++++++++++++++++++++++++++++ 1 file changed, 129 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/vect/vect-18.c (limited to 'gcc/testsuite/gcc.dg/vect/vect-18.c') diff --git a/gcc/testsuite/gcc.dg/vect/vect-18.c b/gcc/testsuite/gcc.dg/vect/vect-18.c new file mode 100644 index 00000000000..88b0fc020c2 --- /dev/null +++ b/gcc/testsuite/gcc.dg/vect/vect-18.c @@ -0,0 +1,129 @@ +/* { dg-do run { target powerpc*-*-* } } */ +/* { dg-do run { target i?86-*-* x86_64-*-* } } */ +/* { dg-options "-O2 -ftree-vectorize -fdump-tree-vect-stats -maltivec" { target powerpc*-*-* } } */ +/* { dg-options "-O2 -ftree-vectorize -fdump-tree-vect-stats -msse2" { target i?86-*-* x86_64-*-* } } */ + +#include +#include "tree-vect.h" + +#define N 64 + +int +main1 () +{ + int i; + int ia[N]; + int ib[N]= + {1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0}; + int ic[N] = + {1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0}; + + char ca[N]; + char cb[N] = + {1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0}; + + char cc[N] = + {1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0}; + + short sa[N]; + short sb[N] = + {1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0}; + + short sc[N] = + {1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0, + 1,1,0,0,1,0,1,0}; + + /* Check ints. */ + + for (i = 0; i < N; i++) + { + ia[i] = (ib[i] | ic[i]); + } + + /* check results: */ + for (i = 0; i
