From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- gcc/testsuite/gcc.dg/vect/vect-95.c | 69 +++++++++++++++++++++++++++++++++++++ 1 file changed, 69 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/vect/vect-95.c (limited to 'gcc/testsuite/gcc.dg/vect/vect-95.c') diff --git a/gcc/testsuite/gcc.dg/vect/vect-95.c b/gcc/testsuite/gcc.dg/vect/vect-95.c new file mode 100644 index 000000000..c03d1965d --- /dev/null +++ b/gcc/testsuite/gcc.dg/vect/vect-95.c @@ -0,0 +1,69 @@ +/* { dg-require-effective-target vect_float } */ + +#include +#include "tree-vect.h" + +#define N 256 + +__attribute__ ((noinline)) +void bar (float *pd, float *pa, float *pb, float *pc) +{ + int i; + + /* check results: */ + for (i = 0; i < N; i++) + { + if (pa[i] != (pb[i] * pc[i])) + abort (); + if (pd[i] != 5.0) + abort (); + } + + return; +} + + +__attribute__ ((noinline)) int +main1 (int n, float * __restrict__ pd, float * __restrict__ pa, float * __restrict__ pb, float * __restrict__ pc) +{ + int i; + + for (i = 0; i < n; i++) + { + pa[i] = pb[i] * pc[i]; + pd[i] = 5.0; + } + + bar (pd,pa,pb,pc); + + return 0; +} + +int main (void) +{ + int i; + float a[N] __attribute__ ((__aligned__(__BIGGEST_ALIGNMENT__))); + float d[N+1] __attribute__ ((__aligned__(__BIGGEST_ALIGNMENT__))); + float b[N] = {0,3,6,9,12,15,18,21,24,27,30,33,36,39,42,45,48,51,54,57}; + float c[N] = {0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19}; + + check_vect (); + + main1 (N,&d[1],a,b,c); + main1 (N-2,&d[1],a,b,c); + + return 0; +} + +/* { dg-final { scan-tree-dump-times "vectorized 1 loops" 1 "vect" } } */ +/* { dg-final { scan-tree-dump-times "Alignment of access forced using peeling" 0 "vect" { xfail {vect_element_align} } } } */ + +/* For targets that support unaligned loads we version for the two unaligned + stores and generate misaligned accesses for the loads.
