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-multitypes-6.c | 66 +++++++++++++++++++++++++++ 1 file changed, 66 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/vect/vect-multitypes-6.c (limited to 'gcc/testsuite/gcc.dg/vect/vect-multitypes-6.c') diff --git a/gcc/testsuite/gcc.dg/vect/vect-multitypes-6.c b/gcc/testsuite/gcc.dg/vect/vect-multitypes-6.c new file mode 100644 index 000000000..5bb4be8c3 --- /dev/null +++ b/gcc/testsuite/gcc.dg/vect/vect-multitypes-6.c @@ -0,0 +1,66 @@ +/* { dg-require-effective-target vect_int } */ + +#include +#include "tree-vect.h" + +#define N 32 + +unsigned int ic[N] __attribute__ ((__aligned__(__BIGGEST_ALIGNMENT__))) = + {0,3,6,9,12,15,18,21,24,27,30,33,36,39,42,45,0,3,6,9,12,15,18,21,24,27,30,33,36,39,42,45}; +unsigned int ib[N] __attribute__ ((__aligned__(__BIGGEST_ALIGNMENT__))) = + {0,3,6,9,12,15,18,21,24,27,30,33,36,39,42,45,0,3,6,9,12,15,18,21,24,27,30,33,36,39,42,45}; +unsigned short sc[N] __attribute__ ((__aligned__(__BIGGEST_ALIGNMENT__))) = + {0,3,6,9,12,15,18,21,24,27,30,33,36,39,42,45,0,3,6,9,12,15,18,21,24,27,30,33,36,39,42,45}; +unsigned short sb[N] __attribute__ ((__aligned__(__BIGGEST_ALIGNMENT__))) = + {0,3,6,9,12,15,18,21,24,27,30,33,36,39,42,45,0,3,6,9,12,15,18,21,24,27,30,33,36,39,42,45}; +unsigned char cc[N] __attribute__ ((__aligned__(__BIGGEST_ALIGNMENT__))) = + {0,3,6,9,12,15,18,21,24,27,30,33,36,39,42,45,0,3,6,9,12,15,18,21,24,27,30,33,36,39,42,45}; +unsigned char cb[N] __attribute__ ((__aligned__(__BIGGEST_ALIGNMENT__))) = + {0,3,6,9,12,15,18,21,24,27,30,33,36,39,42,45,0,3,6,9,12,15,18,21,24,27,30,33,36,39,42,45}; + +__attribute__ ((noinline)) +int main1 (int n, + unsigned int * __restrict__ pic, unsigned int * __restrict__ pib, + unsigned short * __restrict__ psc, unsigned short * __restrict__ psb, + unsigned char * __restrict__ pcc, unsigned char * __restrict__ pcb) +{ + int i; + unsigned int ia[N]; + unsigned short sa[N]; + unsigned char ca[N]; + + /* Multiple types with different sizes, used in independent + computations.
