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-3.C | 54 +++++++++++++++++++++++++++++ 1 file changed, 54 insertions(+) create mode 100644 gcc/testsuite/g++.dg/ext/attribute-test-3.C (limited to 'gcc/testsuite/g++.dg/ext/attribute-test-3.C') diff --git a/gcc/testsuite/g++.dg/ext/attribute-test-3.C b/gcc/testsuite/g++.dg/ext/attribute-test-3.C new file mode 100644 index 000000000..050cbb4ed --- /dev/null +++ b/gcc/testsuite/g++.dg/ext/attribute-test-3.C @@ -0,0 +1,54 @@ +// { dg-do run } + +#define vector __attribute__((vector_size(16))) + +extern "C" void abort(); + +class Star +{ + public: + inline vector float foo() const; + + Star() + { + data.f[0] = 1.0; data.f[1] = 2.0; data.f[2] = 3.0, data.f[3] = 4.0; + } + + private: + union { + float f[4]; + vector float v; + } data; + + friend vector float fTest(const Star &); +}; + +vector float Star::foo() const +{ + return data.v; +} + +vector float fTest(const Star & val) +{ + vector float vf = val.foo(); + return vf; +} + +int main() { + + Star s; + + union u { + float f[4]; + vector float v; + } data; + + data.v = fTest(s); + for (int i=0 ; i < 4; i++) + if (data.f[i] != (float)(i+1)) + 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
