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-1.c | 90 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 90 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/vect/vect-1.c (limited to 'gcc/testsuite/gcc.dg/vect/vect-1.c') diff --git a/gcc/testsuite/gcc.dg/vect/vect-1.c b/gcc/testsuite/gcc.dg/vect/vect-1.c new file mode 100644 index 000000000..21975afa0 --- /dev/null +++ b/gcc/testsuite/gcc.dg/vect/vect-1.c @@ -0,0 +1,90 @@ +/* { dg-do compile } */ +/* { dg-require-effective-target vect_int } */ +/* { dg-require-effective-target vect_float } */ + +#define N 16 + +void fbar (float *); +void ibar (int *); +void sbar (short *); + +/* multiple loops */ + +foo (int n) +{ + float a[N+1]; + float b[N]; + float c[N]; + float d[N]; + int ia[N]; + int ib[N]; + int ic[N]; + int i,j; + int diff = 0; + char cb[N]; + char cc[N]; + char image[N][N]; + char block[N][N]; + + /* Vectorizable. */ + diff = 0; + for (i = 0; i < N; i++) { + diff += (cb[i] - cc[i]); + } + ibar (&diff); + + + /* Vectorizable. */ + diff = 0; + for (i = 0; i < N; i++) { + for (j = 0; j < N; j++) { + diff += (image[i][j] - block[i][j]); + } + } + ibar (&diff); + + + /* Vectorizable. */ + for (i = 0; i < N; i++){ + a[i] = b[i]; + } + fbar (a); + + + /* Vectorizable. */ + for (i = 0; i < N; i++){ + a[i] = b[i] + c[i] + d[i]; + } + fbar (a); + + + /* Strided access.
