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.c-torture/execute/simd-5.c | 59 ++++++++++++++++++++++++++++ 1 file changed, 59 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/simd-5.c (limited to 'gcc/testsuite/gcc.c-torture/execute/simd-5.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/simd-5.c b/gcc/testsuite/gcc.c-torture/execute/simd-5.c new file mode 100644 index 000000000..f05843287 --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/simd-5.c @@ -0,0 +1,59 @@ +/* Test saving and restoring of SIMD registers. */ + +typedef short Q __attribute__((vector_size(8))); + +Q q1 = {1, 2}, q2 = {3, 4}, q3 = {5, 6}, q4 = {7, 8}; + +Q w1, w2, w3, w4; +Q z1, z2, z3, z4; + +volatile int dummy; + +void __attribute__((__noinline__)) +func0 (void) +{ + dummy = 1; +} + +void __attribute__((__noinline__)) +func1 (void) +{ + Q a, b; + a = q1 * q2; + b = q3 * q4; + w1 = a; + w2 = b; + func0 (); + w3 = a; + w4 = b; +} + +void __attribute__((__noinline__)) +func2 (void) +{ + Q a, b; + a = q1 + q2; + b = q3 - q4; + z1 = a; + z2 = b; + func1 (); + z3 = a; + z4 = b; +} + +int +main (void) +{ + func2 (); + + if (memcmp (&w1, &w3, sizeof (Q)) != 0) + abort (); + if (memcmp (&w2, &w4, sizeof (Q)) != 0) + abort (); + if (memcmp (&z1, &z3, sizeof (Q)) != 0) + abort (); + if (memcmp (&z2, &z4, sizeof (Q)) != 0) + abort (); + + return 0; +} -- cgit v1.2.3
