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/abi/empty6.C | 14 ++++++++++++++ 1 file changed, 14 insertions(+) create mode 100644 gcc/testsuite/g++.dg/abi/empty6.C (limited to 'gcc/testsuite/g++.dg/abi/empty6.C') diff --git a/gcc/testsuite/g++.dg/abi/empty6.C b/gcc/testsuite/g++.dg/abi/empty6.C new file mode 100644 index 000000000..1b14a6d03 --- /dev/null +++ b/gcc/testsuite/g++.dg/abi/empty6.C @@ -0,0 +1,14 @@ +// { dg-options "-Wabi -fabi-version=1" } + +struct A {}; + +struct B { + A a; // { dg-warning "empty" "" { xfail mmix-*-* } } + virtual void f () {} +} __attribute__((aligned(2 * sizeof (void *)))); +/* The preceding attribute is necessary on targets with + BIGGEST_ALIGNMENT <= POINTER_SIZE to trigger the warning, as + otherwise the offset of 'a' (i.e. POINTER_SIZE) is split into a + non-zero DECL_FIELD_OFFSET and a zero DECL_FIELD_BIT_OFFSET, + and then there is no discrepancy between DECL_FIELD_OFFSET and + byte_position to warn about. */ -- cgit v1.2.3
