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-shift-2.c | 190 +++++++++++++++++++++++++++++++ 1 file changed, 190 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/vect/vect-shift-2.c (limited to 'gcc/testsuite/gcc.dg/vect/vect-shift-2.c') diff --git a/gcc/testsuite/gcc.dg/vect/vect-shift-2.c b/gcc/testsuite/gcc.dg/vect/vect-shift-2.c new file mode 100644 index 000000000..83211eba4 --- /dev/null +++ b/gcc/testsuite/gcc.dg/vect/vect-shift-2.c @@ -0,0 +1,190 @@ +/* { dg-require-effective-target vect_shift } */ +/* { dg-require-effective-target vect_int } */ +/* Check the standard integer types for left and right shifts to see if the + compiler replaced a scalar instruction with a vector instruction whether the + correct value is generated. */ + +#ifdef TRACE +#endif + +#include +#include "tree-vect.h" + +#ifndef ALIGN +#define ALIGN __attribute__((__aligned__(__BIGGEST_ALIGNMENT__))) +#endif + +#ifndef NOINLINE +#define NOINLINE __attribute__((__noinline__)) +#endif + +#ifdef TRACE +#define TRACE_FUNC(PREFIX, NAME) printf (#PREFIX #NAME "\n") +#define TRACE_DONE() printf ("done!\n") +#define TRACE_ABORT(I,E,G) \ +do { \ + printf ("Element %d, expected 0x%lx, got 0x%lx\n", \ + I, (long)(E), (long)(G));
