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/g++.dg/ext/attribute-test-1.C | 38 +++++++++++++++++++++++++++++ 1 file changed, 38 insertions(+) create mode 100644 gcc/testsuite/g++.dg/ext/attribute-test-1.C (limited to 'gcc/testsuite/g++.dg/ext/attribute-test-1.C') diff --git a/gcc/testsuite/g++.dg/ext/attribute-test-1.C b/gcc/testsuite/g++.dg/ext/attribute-test-1.C new file mode 100644 index 000000000..7df68930f --- /dev/null +++ b/gcc/testsuite/g++.dg/ext/attribute-test-1.C @@ -0,0 +1,38 @@ +// { dg-do run } +// { dg-options "" } +// PR c++/13989 + +extern "C" void abort(); + +#define vector __attribute__((vector_size(16))) + +struct Constants { + inline vector unsigned int deadbeef(void) const { + return (vector unsigned int){0xdeadbeef, 0xabababab, 0x55555555, 0x12345678}; + }; +}; + +inline vector unsigned int const_deadbeef(Constants &C) +{ + return C.deadbeef(); +} + +union u { + unsigned int f[4]; + vector unsigned int v; +} data; + +int main() +{ + Constants c; + data.v = const_deadbeef(c); + + if (data.f[0] != 0xdeadbeef || data.f[1] != 0xabababab + || data.f[2] != 0x55555555 || data.f[3] != 0x12345678) + abort(); + + return 0; +} + +/* Ignore a warning that is irrelevant to the purpose of this test. */ +/* { dg-prune-output ".*GCC vector returned by reference.*" } */ -- cgit v1.2.3
