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/vector6.C | 12 ++++++++++++ 1 file changed, 12 insertions(+) create mode 100644 gcc/testsuite/g++.dg/ext/vector6.C (limited to 'gcc/testsuite/g++.dg/ext/vector6.C') diff --git a/gcc/testsuite/g++.dg/ext/vector6.C b/gcc/testsuite/g++.dg/ext/vector6.C new file mode 100644 index 000000000..9caf8c2f6 --- /dev/null +++ b/gcc/testsuite/g++.dg/ext/vector6.C @@ -0,0 +1,12 @@ +// { dg-options "" } +// { dg-do compile } +// C++/30016, we were allowing conversion between vector types +// and union types which is invalid. + +typedef float __v_4F __attribute__ ((vector_size (16))); +typedef union {__v_4F v; float a[4];} __v4F; +void f(void) +{ + __v_4F b; + (reinterpret_cast<__v4F>(b).a)[1] = 1; // { dg-error "" } +} -- cgit v1.2.3
